WHEN we confider the variety of channels through which literary Improvements are diffufed to the Public, it appears a matter of aftonifhment that, while the ProfelTors of Literature have monthly in- creafed their intelledtual treafures, the Architedls, Surveyors, Carpenters, and Mafons, have been unnoticed, and pafled by as unworthy of the Inftrudtion or afliftance of thofe who are eminent in their refpedlive pro- feffions. Whence this omiflion could proceed, it is not eafy to invefti- gate ; but as it is time that this tribute fliould be paid, a fet of Gentle- men have formed themfelves into a Society to promote the improvement of Architediure. Each of them has dedicated his labours to that particu- lar department, in which he has been principally engaged, and in which he has obtained the palm of excellence. Architedlure, or the art of eredling edifices, is, doubtlefs, of very great antiquity J and was, perhaps, preceded only by agriculture itfelf : Hence Theodore calls the latter the eldeft fifter of Architedlure. The exceiiive heats of fummer, and feverity of winter, the inconvenience of rain, and the violence of wind, foon inftrucled mankind to feek for flielter, and pro- vide themfelves with proper retreats, to defend themfelves againfl the incle- mency of the weather. But thefe at firft were only fmall huts, built very rudely with the branches of trees, and very indifferently covered. In the time of Vitruvius, they fhewed at Athens, as a curious relic of antiquity, the roof of the Areopagus, made of clay ; and at Rome, in the temple of the Capitol, the cottage of Romulus thatched with ftraw. After thefe rude eflays, buildings of wood were introduced, and thefe fuggefted the ideas of columns and aichitraves. But the workmen became every day more induftrious and more expert. Inftead of thofe flight huts which fatisfied them at firft, they began to eredl great walls of Hone and brick upon folid foundations, and to cover them with boards and tiles. And, in procefs of time, their reflections, founded on experience, led them to difcover the juft rules of proportion. Mofes informs us, that Cain built a city. Afia was therefore the cradle of Architedlure, there it had its birth, and there it attained a confiderable degree of perfedlion, and thence it fpread into other parts of the world. It is indeed to be lamented, that not one fingle Treatile, written by the Greeks upon Architedlure, has reached our hands. Tlie only books we have of theirs upon the i'ubjedl, are the ftrudlurts of thole antient niafters ffill fubfifting, whofe beauty is univerfally acknowledged, and which have been the admiration of all good Judges. Thefe ftrudtures are fuperior to all the precepts they could have left us. The Romans borrowed the art from the Greeks; and under Auguftus, when good tafte univerfally prevailed, carried PREFACE. carried it to a great degree of perfection. But it fell with the Weftern empire, and was not recovered for the fpace of twelve centuries. In the two lall: centuries, the Architedls ot Italy, England and France, cm ploy 'd thcmfelves wholly in retrieving the primitive fimplicity and beauty of antient Architecture. Every thing in Architecture is, or fhould be, proportioned to the bulk, flrength, delicacy, richnefs, or fimplicity that is required. Such we mean to reprelent every article in the courfe of this Work. The Public may be afl'ured that the Gentlemen concerned in this performance, will fpare neither labour or expence to render it univerfally ufeful ; and they flatter themfelves they are not unequal to the tafk they have undertaken. Architedts, in general, have, in their publications, confidered the mag- nificence of building, rather than its ufej it fliall be our tafk to unite both } for architedture cannot be more grand than it is ufeful ; nor is its dignity more to be conlidered than its convenience. Though it is our intention lo take the pupil by the hand, and lead him through every branch of Architecture, till he attains the higheft degree of perfection in that noble fcience; yet, in order to render it worthy the attention of every one connected with it, we fhall in every number give Icmething that may be ufeful to adepts in the fcience, as well as to thofe who have but juft entered upon the ftudy of it. We fhall, indeed, in each number, endeavour to introduce fomething in the common way, lomething in a tafte fuperior to that, and fomething elegant and fuperb. By purfuing this method, every clafs of our Readers will find fomething toinftruCt and entertain. This Performance will confift of two parts, viz. theoretical and pradti- cal. The theoretical parts fhall confift of fuch inflrudtions as are necef- fary to form the complete Architedt ; and the pradtical part fhall furnifh Plans, Elevations, Sedtions, &c. with their Explanations, as models for the pradliical Builder. The two parts are feparately paged, that, at the conclufion of the Work, tliey may be bound feparate : and we flatter ourlelves, that the Purcha- fers will then be poflefTed of a Complete Body of Theoretical and Prac- tical Architedture. As we propofe to begin our Theory with the moll fimple inftrudtions, and advance progreflively to the fublime parts, we propofe, as a founda- tion, to give an alphabetical defcription of all the terms of art which are ufed in Baildinir. •a' ALPHA- C I 1 ALPHABETICAL [DESCRIPTION^ o r T H £ Terms of Art which are ufed in Building ; fORMiNG AtSO A COMPLETE BUILDER 'S DICTIONARY. ABACUS, the fuperior member of the capital, to which it ferves as a kind of crown, on which the architrave refts ; tenuinating the co- lumn w>th its capital at the top, as the Plinth, another fquare pitce, does Vi'ith its bafe at the bottom. It is faid the original of the Abacus was a fquare tile, laid over a bafket, round which leaves of the Acanthus or Bear's breech grew ; whence the Corinthian capital was derived. But the Abacus is certainly of earlier orit^in It is well known, that the Doric order was long prior to the C orinthian ; and there is an Abacus on that in^ the remains of the Parthenion at Athens, though the columns have no bafe. It reprelents a tile indeed in the Corinthian order, but its four fides are fegments of circle^. In the earlieft inrtances it ferved only to give breadth to the top of the columns, and a level fupport to the entablature. For this reafon we fee the Abacus of the Doric capital, very large in the moft ancient buildings. In the infancy of Agriculture, trunks of trees were railed upright for columns, and others laid acrofs them to bear the roof. The Abacus was then a Iqiare piece, added to the top of the column, to iupport thofe others more conveniently. The Abacus was then made fquare and plain on the fides, as in the ancient Doric; and in the Tufcan, added by the Romans ; but in the Corinthian and Compofite, it i- altered. Its four IJdes are hallowed or arched inwa;ds, and it is decorated in the center with a flovver or other ornament, Jn the Tuican order, the Abacus is of a great thicknefs, and is called, bv fome the dye of the capital ; in the later Doric, a cymatium is fometimes put over it, fo that it lofes even- its place: an.l in the Ionic, it is wrought with ^n oval crowned with a fillet ; or it is compofed ot a ct>na rever a and filL t only. In the Tufcan order, the Abacus is ut the fame form >a ith the plinth of the bafe. In the richer orders, it lofcs its native; lorm, the fou. fides or faces uf it beinp-; arched or cut inwards with lome ornament as a rofe, or othei fiower; the tail of a fifh, ficc. in the ii;ijdle of each arch.- Oth'its tell us, that in theCoiin hian and Co polite, it is compofed of an ovokx, a fiitet, and a cavctto. Andrea Falliaio, in the Tufcan order, gives the name of Aba- cus to the phnth above ths echynus, or boultin ; which he fays is ulually B called I ] called a dado or dye, from its form, and is one-third of the whole height of the capital. He alfo defcribes the Abacus of the Corinthian order to be one-feventh part of the whole capital, divided into three parts, the up- permofl: of which is a boultin, and one-third of the next third below is the fillet, and the remaining part below, which is one and two-thirds, is the plinth and the Abacus. The Abacus is not always reflrained to the capital of the column, Scamozzi ufing it in a very different fenfe; viz. a concave moulding in the capital of the Tufcan pedeftal. AbreuvoiRj or Abrevoir, in Mafonry, llgnifies the joint or junfture of two ftones, or the fpace or interftice to be filled up with mortar or cement. Abuttals, (from Aboiith, fr. to border upon) the buttings and boundings of land, either to the eaO, weft, north, or fouth, fliewing on whatever lands, ftreets, highways, &c. the leveral extremes abut or ter- minate. Camden obferves, that limits were formerly diftinguilhed by hillocks raifed on purpofe, which were called botentines, whence we have the word buttings. Abscisse or Abscissa, in Conies, any part of the diameter or axis of a curve, contained between its vertex, or lome other fixed point, and the jnterfedion of an ordinate. Such is the line AO, contained between the vertex A of the curve BAC. The \^■'6'rd is dsrlvcd from a^.fcindete, ito cut off. In the parabola, the abfcifle is a third proportional tothe parameter and the ordinate. Jn the ellipfis, the iquareof the ordinate is equal to. the rcdtangle under the pa- rameter and the abfciffe, kffened by another rtdtangle under the faid ab- fciffc. In the hyperbola, the Iquares of the ordinates arc as the redan- gles of the abfciffe, by aaother line compounded of the abfciffe, and the tranfverfe axis. !n ihefe two propofitions, relating to th.e ellipfis and the hyperbola, the origin of the abfciffes, on the point A, from whence they begin to bcfeckone^l, k fuppofed to be the vertex of the curve, or, which amounts to the fame, the point where the axis meets it^ for if the origin of the abfcifles be taken from the center, as is frequently done, then the two foregoing thei^rems no longer hold good. Acanthus, r 3 ] Acanthus, in Botany, a plant producing an irregular, monopetalous flower, terminated in a ring at the bottom. It is called in Englifli Bear's Breech; the leaves of which make an ornament in the Corinthian and Compofite orders. There are two fpecies of plants of the fa-ne name; one of which is wild, and the other cultivated in gardens. The firfl; is, called in Greek Acantha, which fignifies a thorn, oh account of its having prickly leaves ; and in that which the major part of the Gothic fculptors have imitated in their ornaments. The fecond is called in Latin Branca urfina, becaufe they pretend it refembles a bear's foot. The ancient and modern fculptors have preferred the latter, and make ufe of it particularly in their capitals. Vitruvius'fays, that this plant gave occafion to Cailima- chus, the Grecian fculptor, to compofe the Corinthian capital. It hap- pened as follows. An old woman of Athens, happening to place a bafket, covered with a little tile, over the root of an Acanthus, which grew on a young lady's grave at Corinth ; the plant (hooting up the fol- lowing fpring, entirely encompafled the bafkct, till, meeting with the tile, it curled back in a kind of fcrolls. Pafling by, he obferved ir, and immediately executed a capital on this plan, reprefenting the tile by the abacus, and the leaves of the Acanthus by the volutes or fcrolls; and the baiket (which the French call Tambour) by the vafe or body of the capital. Garden Acanthus is more indented than the wild, and more re- fembles parfley or fmallage, as it is found reprefented in the Compofite capitals of Titus, and Septimius Severus, at Rome. The place of the Acanthus leaves is on the ball of the capital, which they cover ; and they are the diftindlion of the two rich orders from the three others ; and their difpofition, in a feparate manner on ihefe two, diflinguiflies them from one another. The Greek fculptors have taken feme liberties in their rcprefen- tations of the leaves of th'rs plant. Sometirnes the indentings are tou deep, i and ofien too numerous for nature. They alfo introduce olive leaves and laurel leaves in the divifion ; but they crave them with fo much freedom^ ' and with fo little regard to truth, that, like herald-paintings, if we' were not told what they reprefent, we fhould find it dithcult to«gusfs. ■ ' AccELiERA'TED MoTiON, in Mcchinics, is that whofe velocity is ' conftantly increafed ; and if the accefTions of velocity be equil in tq lal * times, the motion is faid to be unifotmly accelerated. 1 his cofr.es chiefly t under confideration, in the defcent of heavy bodies, by the force of gra- vity. Notwithftanding various opinions on this fubjedt, thecaufec;t dc~ ' cchratioii is nothing myfterious; the principle of gravitation, which deter- mints the body to defcend, determining it to be accelcratea by a neceC-''" fary confequence. A body having once began to defcend through thd im- pulfe of gravity, that ftate is now, by Sir Ifaac Newton's firfblaw; become as it were natural to it, infomuch that, were it left to itielf, it would for ever continue to defcend, though the firftcaufeof its defcent ihould cesle. I 4 } But, befides this determination to defcend, imprelTed upon it by the firfl caufe, which would be fufficicnt to continue the degree of motion already began to infinity, new impulles are continually fuperadded by the fame caufe, which continue to ad: upon the body already in motion, in the fa nc manner as if it had remained at reft: there being then two caufes ot mo- tion, ading both in the fame diredion, it neceff.rily follow , that the motion which they unitedly produce, muil: ne more confiderable t an what either could produce feparately ; and, as long as thevel ^city is thus increafed, the fame caufe ftill fubfifting to increafe it yet tnore. the delccnt muft of necedity be continually accelerated Suppofing that gravity, from whatever principle, ads uniformly upon all bodies, at the fame diliance from the center of the earth, dividing the time which the heav/ booy takes up in falling to the earth into infinitely fmall equal parts, ti is gra« vity will imptll the body towards the ce iter of the earth, in the fit ft infi- nitely fhort inftant of the defcent. If, after this, we fuppo e t! e adion of gravity to ceafe, the body will continue perpetually to advance uniform- ly towards the earth's center, with an infinitely imall velocity, equal to that which refulted from the firft impulfe. But then, if we luj-ipole that the adion of gravity continues in the fecond inftant, the body will receive a new impulfe towards the earth, tqual to that which it received in the firft inftant, confequently its velocity will be doubled j in the third iniiant it will be tripled j in the fourth quadrupled ; and fo on. For the impulie made in any preceding inftant, is no ways altered by that which is made in the following one ; but they are accumulated on each other: whcrclore, the infiants of time being fuppofed infinitely fmall, and all tqual, the ve- locity acquired by the falling body will be, in every inftant, as the times from the beginning of the defcent, and conftquently the velocity will be proportional t© the time in which it is acquired. The motion of an af- cending body, or of one tJjat is impelled upwards, is diminifhcd or re- tarded by the fame principle of gravity, ading in a contrary dircdion, -after the fame manner that a falling body is accelerated. A body piojeded upwards, alcends until it has loft all its motion, which it does m the ^'ame interval of time that the fame body would have taken up in acquiring by falling, a velocity equal to that with which the falling body begun to be projeded upwards, and confequently the heights to wnich bodies projeded upwards, with oifTcrcnt velocities, arrive, are to each other as the Iquare of tho:e vtlociiits. AcciDHNTAL Point, in Perfpedive, the point in the horizontal line, where the projedions of two lines, parallel to each othei, meet the re- fpedive plane. AccL.viTY, the flope or afcent of a line or plane, confidered in its af- cending diredion ; as the alcent of an hill is the acclivity ; and, on the contrary, the defcent is the declivity. The woid is compounded of ad, and clivus, a llope. Some writers have ufed the term Acclivity as fynoni* mous AJU '^S Vri'ous With talus ; but the latter properly fignlfies the flope in general, whether it be confidered as afcending or defcending. AcROTERiA, improperly called Acroters, in Architedure, fmall pedeftals, upon which globes, vafes, or Itatucs, are placed at the end or center of pediments, or frontiipieces. According to Vitruvius, the height of the Acroteria, at the extremities, fliould be only one-half of that of the tympanum; whereas that in the center ought to be one eighth more. Acroteria alfo fignify the figures placed as ornaments or crownings on the tops of churches J and fometimes thofe {harp pinnacles, ftanding in rows about flat buildings, with rails and balufters, are called Acroteria. The word is Greek, and fignifics the fummit or higheft p:iint of any thing. Aerial Perspective, that which is reprefented both weak and di- minished, in proportion to the diftance from the eye. It is founded on this, that the longer a column of air an objed: is feen through, the weaker do the vifual rays emitted from it affed the eye. The obj .ft of Aerial Perfpedlive is principally colours of objeds, whofe force and luftreit takes ■off more or lefs, to make them appear as if more or lefs remote. Ajutage, or Adjutage, in Hydraulics, a imall pipe ntted to the aperture of a Jet d'eau, or fountain. Experiments have (hewn, that a re- fervoir of 12 feet height above the orifice of an Ajutage of three lines dia- meter, delivers 14 Paris pints of water in a minute. This may ferve as a fundamental rule for fountains, affifl:ed by the following principles. When tlie height of the refervoirs is the fame, and the orifices of the Ajutages different, the expence of water is proportional to the fqaares of the dia- meters of the Ajutages, when the expence of water, through different Ajutages, is thus computed. If 9, the fquare of 3, gives, by experiment, 14 pints, what will an Ajutage of 5 or 6 lines give. The anfwtr is, 39 pints for 5, and 56 pints for 6. If the expence of two refervoirs of un- equal heights, and different Ajutages, be required, proceed by the follow- ing rule. The expence of water of two reiervoirs, whofe heights are different, and alfo their Ajutages, are in the compound ratio of the fqua-es of the diameters of the Ajutages, and of the fubduplicate ratio of the heights. Water fpouting upwards, through an Ajutage, would alcend to thefame height as that of its upper furface in the relervoir, wero it not for the refillance of the air, the fridlion at the fides of the Ajutai,e, and fome little impediments at the motion of the water in itielf; on account of v>'hich, the height of the rife is always defedive. It i? found, by ex- perience, that if the diredlion of the Ajutage be a fmall matter inclineJ, the waier will rife higher than if it be truly upright ; ani that a poliflieJ round hole, in a thin plate of metal, at the top of the pipe, by way ot Ajutage, will fuffer the water to fpout higher than when it is cylindrical dr oonical. Experience alfo fliews, that the bignefs of the pipe oi the Ajil- ^age (hould be enlarged at and near the fuiface of the water in the reier- C voir. 6 ALA voir, and that fuch pipe fliould he much larger than the Ajutage : alfo that there is a certain length among the feveral diameters of the Aiutages, which will fpout the greateft height poiiihle, and which muft not exceed an inch and a quarter. Likewife, tiie height of the fpout muft ha^e its limits,, loo feet being almoll- as much as it will bear. Let it be obferved, i. that tlie fquares of the quantities flowing out from the lame Ajutage in equal timep, arc in the ratio of the heit^hts of the liquid above the aperture. 2. The times in which cylindrical veirds ot the fame diameter and height are emp- tied, the liquid flawing from unequil apenures, are in the inverfe ratio of the areas of thofe aperture^. 3. Cylindrical vefTek of unequal bafes, but of equal heights, a-^e emptied through equal apertures in times that are in the ratio of their bafcs. 4. The ti iifs in whicli any cylindrical vellels are evacuated, are in a ratio compounded of the bafes, the inverfe ratio of the apertures, and diredl ratio of the Iquare roots of the heights, li the fide of a cylindrical veffel, beginning from the bale be divided into lengths, which are as i, 4, 9, 16, &c viz. the fquares of the natural numbers, 1, 2, 3, 4, &c. the furface of the water (running out through an hole or aperture at the bottom) will defcend from each of thole divifions to the next, in the fame time. In the above invefligations, we always juppofe the velocity of the efHuent water to remain conltant during the evacuation ; and therefore, when we fpeak of the time of emptying a cylindrical veflel^ we only mean that time in which (the veflel being kept ci.,nllant)y full; a quantity of the liquid, equal in magnitude to the capacity of the veflel, v/ill flow through the Ajutage, or aperture, in the fide of the perpendi- cular cylinder. Alabaster, A^cbaflrites, in Natural Hiftory, the name of a genus of foffils, nearly allied to marble. It is an elegant flone of great bnght- nefs, and will receive a finepolifh, but is brittle. Naturaliits enumerate feveral fpecies of alabafter j as, the Inow-white fhining alabafter. Boet informs us, that this flone is extremely white, and found in Taurus in pieces only large enough to make diflies and the like ; but it was formerly brought from Arabia. It is not very compadl, but heavy, and conlills of a multitude of broad flat particles, which are very bright, and per ediy white. It cuts very freely, and is capable of a fine polilh. There are very large ftrata of it in Arabia, Egypt, and many pirts of Italy. Whitifh yellow alabafter is of a foft conliilence, and Crlltd by Boet, the Phengites ot Pliny, who affirms it was found in C^ppadocia. It is of a loofe open texture, confiderably heavy, and nearly ot tne colour of honey 1 but ihe colour is more deep in fome places than in others, it conlills of irregular pieces lying in tiibles one over another, though with regularity, and altogether compofe a remarkable bright and very brittle mals. Bclidcs the places above-mentioned, it has been tound in Germany, France, and Dcrb)'{hire. Yellow and leddilh variegated Akbalicr is the common Alabarter A L D 7 Alabarter of the ancients. It is fo foft, that it may be cut with a knife ; and hi the fame name in all langn j therefore, for materials of the above quality, a mafter in jus- tice fhould have per rod 81. los. But in order to come at a real flan dard of prices for brick-work in any county, I beg my reader to have recourfe to the 1 Rowing table, calculated as univerfal, allowing the mafter for lime, iand, and making the mortar, jl. 3s. and for labour il. 5s. Aa univerfal Table of Brick-work, allowing il. 3s. Mortar, and li. 5s. Labour. At 10 — — 28 — — is Bricks per 1000..

If a mafter-bricklayer ftipulates all his work at one price, as fronts, foundations, and party-walls, one thing will m-ke amends for the lofs of another. The price fhould be what I have mentioned prior to the table ; though mafters would grumble at this price j becaufe being only allowed ll. per rod profit, which I think very fufficient; for by this rule, if a mafter can but employ twelve trowel-men the year round his bufinefs will be a good 500 1. per annum, allowing one hundred per ditto for bad debts, and keeping up his fcaffolding. Whether this is lufficient or not I leave to the judgment of the world, But I fay, if from fuch prices (which are confidenibly lefs than many maflers have) thefe genteel profits arife, what fhall we fay to lol. and 12 1. per rod, which I have known many bricklayers charge for common brick-work ? But the laft is exorbi- tant, and ought to be utterly aboliflied. There are indeed pariicular jobbs, as warchoufes of a particular height that ftand clofe to the Thames, where one labourer is not fufficient to half ferve one bricklayer, and where dou- ble the trouble is required to erect the fcafFold, &c. In thefe cafes 12 1. per rod may not be amifs I would not willingly infer, or be fuppoled to infinudte, that the above prices fhould be lowered ; but will take the liberty to fay, if a mafter is allowed 9 1. or 10 1. per rod, he ought to augment his journeymen's wages ; a thing which ought to be maturely tonlidered in every branch of building. I make no doub". but fome people will wonder how I can fo eafily re- concile this giving as much for labour to a country mailer as a London one, in bufinels like a bricklayer, and fo eafily attained. To the perlon that m.ikes this objection, I give the following anfvver ; that there is a flig! t in brick-work as well as in every other practice, and t at brick- Ia)'ers in London are obliged to do one-third more work than in the coun- try is ever dtfired : befides, in point of labourers with regard to their prices, uhich in London are confiderably more than the country, and with juliicc too; lor could you have a country labourer in London, you would ARC 19 would find he would not be able to half-ferve a bricklayer, without a year's experience A rod of brick-work in the country is, by men that have not had London pradice, five and a half days work, and in fome places fix j nay, I have even known a brick-layer in the country, and v/ho was efteemed a ^ood workman, to be eight days over-walling a rod, and all this time a labourer to attend him ; which, if we rightly confider, will produce the country mafters lefs profits by much, and not to have w ork forhalf the number of men. To a gentleman that finds his own materials, fcaffolding, &c. a mafter fliall have from il. Ss. to 1 1. 16 s. per rod labour, according to the good- nefs of the work. The ftandard price by many furveyors is il. 10 s. The marters prices, where no furveyor is concerned, are trom il. 16 s. to I 1. 18 s. which will allow for men to have 3 s. 6d. per day, which ought to be the journeyman's price, as brick-laying is but an half year's bufinefs. It is hoped our readers will pardon this digreflijn, as we fliall now re- turn to the fubje(ft of arches. .. ,. Arch of a circle, is a part of the circumference of it lefs than half a lemicircle. The bafe or line that joins the two extremes of the arch, is called the chord ; and the perpendicular raifed in the middle of that line, is the fine of the arch. Every circle is fuppofed to be divided into 360 deerees, and an arch is eflimated accordins: to the number of thefe de- grees it takes up. Thus an arch is faid to be 20, 30, 50, 80, 100 decrees Equal Arches, are thofe which contain the fame number of degrees, and are cut from the fame circle, Similar Arches are thofe which contain the fame number of degrees, but cut from unequal circles. Sir Henry Wooten fays, an arch is a narrow contradled vault, and a vault a dilated arch. Arches are ufed in large intercolumnations of fpacious edifices , in por- ticoes, both within and about temples ; in public halls, as cielings ; the courts of palaces, cloifters, theatres, and anti-theatres. An arch in geometiy, is any part of the circumference of a circle or curved line, extending from one point to another. An arch in mafonry, contains a number of fiiones, hewn out and wrought, which when fet in their proper places, are as one folid circular courle, whofe .lower ends form any part of .a circle or curved line, calcu- lated to fupport any wei^fht, proportionste to their ftrength and figure. Sir Henry Wooten, in his Theorems, oblervts, that "All lolid materials, free from impediments, defcend perpendicularly, becaufe pondercfity is a natural inclination to the center of the earth, and nature ptrforms her mo- tions by the fl:iorteft lines." This evidently proves, that all arch itones muil: 20 ARC muft be drawn from their central points to form the curve; othervvirc their bearings will be rendered imperfed:. Semicircular Archks, are thofe arches which are an exadl femicircle;; and have their center in the middle of the diameter (or chord of the: arch) or the right line that may be drawn between the feet of the arch. Of this form the arches of bridges, windows of churches, and' great gates, are. frequently made in modern buildings. Scheme or Skeen Arches, are thofe which are lefs than a femicircley. and confequently are flatter arches, containing fome go, fome jOt. and others 60 degrees. Semicircular arches are ealily diftinguiftied from fcheme arclies thus j That the chord or right line, drawn between the feet of a femicircular arch, is jull double to its height (being meafured from the middle of the chord to the key- piece or top of the archj whereas the chord of a fciieme arch of 96 degrees, will be more than four times its height, and the chord of a fcheme arch of 60 degrees, will be more than fix times its height. The famous Alberti, in h\s arc bit eSJiir a, has the following oblervations. In all openings, in which we make arches, we ought to contrive never to have the arch lefs than a femicircle, with the addition of the feventh part of half its diameter, the moft experienced workmen having found that arch to be much befi: adapted for enduring, in a manner, to perpetuity; all other arches being thought lefs flrong tor fupporting the weight, and more liable to ruin. It is alfo thought, that the half circle is the only arch that has noocca- fion, either for chain, or any other fortification ; whereas all others are found, bv experience, either to burft out, or fall to ruin by their own weight, if they are not chained, or have not fome weight placed againft them lor a counterpoife. I will not omit, continues he, what I have obferved among the antients, a very excelleat and commendable contrivance ; their bell archite(fls placed thefe apertures, and the arches of the roofs of temples, in fuch a manner, that if you even took away every column from under them, they would ftill remain firin and not fall down : the arches, on wh.ch the roof was placed, being drawn quite down \o the foundation, with aftonifhing art, known only to a few ; fo that the work upheld itfelt by being only fet upon arches j for as thofe arches had the folid earth for their cham, it is not to be wondered at that they flood firm without any fupport. The dodtrine and ufe of arches is well delivered by Sir Henry VVooten in the following Theorems. Theorem I. All matter, unlefs impeded, tends to the centre of the earth in a perpendicular line, or defcends perpendicularly downwards. Theorem II. All folid materials, as bricks, ifones, &c. moulded in their common reilangular form, if laid in numbers, one by the fiae of another, r- ARC 21 another, ki a level row, and their extreme ends fuftained between two fupporters, all the pieces between will neceffarily fink, even by their own natural gravity; and rnuft much more, if they are preffed down, or fuffcr any preffure by a (uper-incumbent weight ; becauie their fides being pa- rallel, they have room to defcend perpendicularly without impediment, according to the lormer theorem; therefore to make them ftand, either their figure or their pofition muff be altered. Theorem III. Stones, bricks, or other materials, being figured cune- atim, /. e. wedge-wife, fomewh.tt broader above than below, and laid in a level row. with their two extremes fupported, as in the preceding theorem, and pointing all to the lame centre ; none of the pieces between can fink, till the fupporters or butments give w^y, becaufe they want room in that fituation, t- defcend perpendicularly. But this is a weak flrufture ; be- cauie the fuppoiters are iubjed to too much impulfion, efpecially where the line is long ; for which realon, this form of ftraight arches is feldom ufed, but over doors and windows, where the line h (hort. Therefore, in order to fortify the work, the figure of the materials muft not only be changed, but the pofition of them too; as will appear in the following theorem. 7 heorem IV. If the materials be fhaped wedge-wife, and difpofed in the form of a circular Arch, and pointing to fome centre : in this cafe, neither the pieces of the faid Arch can fink downwards for want of room to defcend perpendicularlv, nor can the fupporters or butments of this Arch fuffer io much violence, as in the preceding platform, for the round- nefs, or rather cnvexity, will always make the incumbent weight rather reft upon the fupporters, than heave or fhove them outwards ; whence this corollary may be fairly deduced, that the lafeft or moft fecure ot all the Arches above-mentioned, is the lemicircular; and of all vaults ; the he- mifpherical, although not abfuljtely exempted from fome natural imbeci- lity, ( which is the fule prerogative of perpendicula • lines and right angles) as has been obferved by Bernardino Baki;, Abbot of Guaftalla, in his Commentary upon Ariftotle's Mechanics; where by the way, it is to be noted, that when any thing is demonftrated mathematically to be weak, it is much more fo mechanically ; errors alwa\s occurring more ealily m the management of gfols materials, than in lineal dcligns. Theorem V. As lemicircular Arches, or he nifphericai vaults, raifed on the whole diameter, are the ftrongeft and fecureft by the picceding theorem, fo they are alfo the moft beautiful ; which keeping precilely to the fame height, are yet diftended one louiteenth part knger than the faid diameter : which addition of width will contribute greatly to their bcituty, without diminiftiing any thing confideiar)le of their ftrength. However it is to be obierved, that according to geurattrical ftrid:aels, in G order 2> ARC order to have the iTirongeft: Arches, they muft not he portions of circles, but (f another curve, cal ed, the ca enaria ; the nature of which is fuch, tJiat a number of fpheres dilpoled in -his fo'in, will luftain each other; and form an Arch. Dr. Gregory, Phil. Tranl. No. 231, has fliewn, that Arches conftrutfled in other curves, only ftand or luftain tiiemfelves by virtue of the catenaria contained in their thicknefs ; lo that if they were made infinitely flender or thin, they muft of ccurle tumble j whereat the catenaria, though infinitely flender, muft ftand, by reafon that no one point of it tends downwards more than any other. Of meafuring Arches. Whether the arches befl:raightor circular, they -muft be meafured in the middle, i e. if a llraight arch be ten inches in height, or depth, the length muft be meafured in the middle of the ten inches ; which length will not be any longer, than if it were mea- fured at the under fide next to the head of the window, by fo much as one fide of the fpringing arch is turned back from the upright ot the jaumbs, peers, or coins of the windows. And alio in circular Arches, it is to be obferved, that the upper part of the Arch is longer (if girt about) than the under part, becaufe it is the fegment of a greater circle, cut off by the fame right line that the leiTer is, and therefore muft be girt in the middle. Architect, a perfon flcil'ed in architedture, who not only draws the plans of edifices, but alfo fuperintends and dirc-fts the artificers It is his bufinefs to confider the whole manner and method of the building, and alfo to calculate the expcnce. In the management of which he ought to have regard to its fituation, contrivance, ftrength, beauty, form, and ma- terials. 1 he term Architedl is alfo ukd forthe furveyor or fuperintendant of an ediiice, the management being wholly commit ed to his circum- fpedlion. Vitruvius enumerates twelve qualifications requifitefo- a com- plete Architedl, viz. that he be docile and ingenious, littrate, ilcilled in Defi^ning, in Geometry, Optics, Arithmetic, Hiftory, Philofophy, Mu- fic. Medicine, Law, and Alhology, The moft celebrated Archi edls among the antients, are Vitruvius, Palladio, Scamozzi Serlio, Vignola, ■Barbaro, Cataneo, Alberti, Vida, Bullant, Ue Lorme, and many others. Akchitectonip, fomething endowed with the power and fkill of i>uilding, or calculated to afiili the archited:. Architecture, the art or fcience of eicding edifices, either for ha- bitation or defence. It gives the rules for defigning and raifing all forts of rtrudures, according to the rules of Geometry and proportion, and includes, all thofe arts which conduce, in any degree, to the framing of houles, temples, palaces, Sec. The Icheme, or projection of a builoing, is ulually laid down in three feveral defigns or draughts. The firft i& a plan, which exhibits the extent, divifion, and diUribution of the ground into ARC 23 into apartments'and other conveniences. The fecond (hews the ftories, their heigh s, and the external appearances of the whole building: and this is ufualiy called the defign or elevation. The third is commonly called the fection, and fliews the infide of the fabrick. From thefe three defigns, the furveyor makes an eftimate of the charges of the v^hole building, and the time requifite to complete it. As to the antiquity of Architedure; Architedure is hardly inferior, in point of antiquity, to any other art. Nature and necelTity taught the firft inhabitants of the earth to build or eredl huts, tents and cottages ; from which in procefs of time, they gradually advanced to erefting more regular and ftately dwel- lings, adorned with variety of orn ^ments, proportions, &c. Antient writers alcnbe the carrying of Architedure to a confiderable height to the Tyrians, who were therefore fent for by Solomon to ered his temple. But Villapandus will not allow thofe who were fent for from Tyre, to be any more than inferior workmen, fuch as artificers in gold, filver, brafs, &c. and fuppofes that the rules of Architcdlure were delivered by God himfelf to Solomon. So that the Tyrians rather learned Architecture from Solomon, than Solomon irom them; which they afterwards com- municated to the Egyptians, the Egyptians to the Greeks, and the Greeks to the Romans. He undertakes to prove, that all the beauty and advan- tages of the Greek and Roman fabricks were borrowed from Solomon's temple. Sturmius produces feveral paffages in Vitruvius in confirma- tion of this, where the rules, laid down in his lib. iv. c?.p. 11. and lib. v. cap. I. correfpond exadlly with what Jofephus relates of the Jewifh tem- ples, in his fixth book. But the twenty-third chapter of Ifaiah, ver. 8. informs us to what a pitch of magnificence the Tyrians and Egyptians had carried Architediure before it came to the Greeks ; and Vitruvius alfo gives an account of the Egyptian occus, their pyramids, obeliiTcs, &c. Yet, in the general account, Architedture feems to be wholly of Greek original. Three of the regular orders or manners take their names from the Greeks, as Corinthian, Ionic, and Doric ; and we have fcarce a part, a fingle member, or moulding, but what is tranfmitted to us with a Greek name. And it is certain the Romans, from whom we take it, borrowed all they knew entirely from the Greeks j nor do they feem to have had, before, any other idea of the grandeur and beauty of fuperb buildings, but what arifes from magnitude, ftrength, &c. Archiiedfure is fuppofed to have arrived at its glory in the tinie of Au- guflus Caifar; but that, as well as other polite arts, were negledted under Tiberius. Nero, indeed, notwithftanding his vices, retained an uncom- mon paflion for Architecture; but luxury and dilfolutenefs had a greater fliare in it than real magnificence. In the time of Trajan, Apollodoius excelled in the art ; by which he obtained the favour of that prince, and ereded that famous column, called'Trajan's, which is remaining to this day. 24- A U C day. But after this time, Architefture began to decline ; though h was, fyrlbme time, fupported by the care and magnificence of Alexander Seve- rus ; yet it fell with the Wcftern empire, and funk into corruption ; from whence it did not recover for the fpace of 1200 years. All the moft beautiful monuments of antiquity were deftroyed by the ravages of the Vifigoths; and from that time, Architecfture became fo coarfe and artlefs, that their profeffed architects were totally ignorant of jufl: dcfigning, wherein the whole beauty of Architedlure confifts : hence a new manner of Architecfture, called Gothic, took its rife. Charlemagne induftrioufly laboured for tlie reftoration of Architefture : and the French applied themiclves to it with fuccefs, under the encou- ragement of Hugh Capet. His fon Robert profecuting the lame defign, the modern Architedture, by degrees, ran into as great an excefs of deli- cacy, as the Gothic had before done of maffivenefs. To thefe we may add the Arabefk, Morefk, or Moorifh Architecture, which were much of the fame nature with the Gothic; except, that as the former was brought from the North, by the Goths and Vandals, the Utter was hroii^ht from the South, by the Moors and Saracens. The Architeds of the thirteenth fourteenth, and fifteenth centuries, who had fome knowledge of fculp- ture, feemed to make perfedion confift wholly in the delicacy and multi- tude of ornaments, which they laviflily beftowed on their building; but frequently without condudt or tafle. In the two laft ceniurieb, the Ar- chitedts of Italy and France affiduoufly erideavoured to retrieve the pri- mitive fimplicity and beauty of antient Architedture ; nor did tliey fail of fuccefs : infomuch, that now our churches, palaces, 6cc. are built en- tirely after the antique. Civil Arcbitcdure may be diftinguiflied, with refped: to the feveral pe- riods or Rates of it, into Antique, Antient, Gothic, iModern, &c. Ano- ther divifion of Civil Architecture arifes from the different proportions, which the different kinds of buildings rendered necefTary ; that there might be Ibme adapted to every purpole, according to the buik, ftrength, delicacy, richnefs, or fimplicity required. Hence proceeded the five or- ders or manners of building, all invented by the ancients, at different times, and on different occafions, viz. Tulcan, Doric, Ionic, Corinthian, -and Compofite. That which forms an order, is the column, with its bafe and capital, furmounted by an entablature, confuting of architrave, freeze, and cornice, fuftained by a pedeftal. We have no Grttk authors now extant, on Architecture: the hrfl who wrote upon that fubjecft, was Agatnereus, the Athenian. He was feconded by Democritus aiid 1 heo- phraflus. Of all theantients, Vitruvius is the only author we have en- tire ; though he relates, that there were feven hundred Architedts in Rome in his time. Vitruvius, in the time of Auguftus, wrote a complete byl- tem of Architcituie, in tea books, which he dedicated to that prince. The A R C 25 The moderns cenfure two things in this excellent work, viz. want of method and obfcurity. The mixture of Latin and Greek in Vitruvius, is fuch, that Leon. Babtift. Alberti has obferved, that he wrote Latin to the Greeks, and Greek to the Latins : he alfo fays, that there are a- bundance of things fuperfluous and foreign to the purpofe contained in that performance. For this reafon, M. Perrault has extradled all the rules out of the prolix work of Vitruvius, methodized them, and pub- liflied them in a fmall abridgment. Several authors have attenipted to explain the text of Vitruvius, particularly Philander, Barbaro, and Sal- mafius, in notes added to their feveral editions in Latin ; Rivius and Per- rault, in the notes to their German and French verfions j and Baldus. in his Lexicon Vitruvianus. M. Perrault has alfo compofed an excellent treatife of the five orders, which may be confidered as a fupplcment to Vitruvius, he having left the dodfrine of the orders imperfect. The authors who have written on Architedlure fince Vitruvius, are Leon. Baptift. Alberti, who publifhed in Latin ten books of the art of building, defigning to outvie Vitruvius ; but he has not, however, fuc- ceeded in his defign, though his books contain a number of excellent things ; for he is deficient in the dodlrine of the orders. Sebaft. Serlio alfo wrote feven books of Architedture, five of which were concerning the five orders, and were publifhed in ibo2 ; through the whole of which he flridly adheres to Vitruvius's rule : the feventh was publidied afterwards, in the year 1675. Philip de Lorme publifh- ed nine books of Archite(fture, in French, in the year 1667. J. Baroz- zio de Vignola publi'hed his rules of the five orders, in Italian in the year i68r ; which have been fince tranflated, with confiderable additions, by Davilcr, under the title of Conrs d'ArckiteBure. Alio Vincent Scamozzi's Idea of Univerfal Architedlure was publiflied in Italian, in the year 1615 ; and Car. Phil. Dieuflart's Theatre of Civil Architeduie, was publilhed in High Dutch, in the year i6gj ; in which he not only de- livers the rules of ArchiteiSlure, but alfo explains and compares the five orders, as laid down by Palladio, Vignola, Scamozzi, &c. R. Freart de Cambray alfo purfutd the fame defign in French, in a parallel of the antient Architedlure with the modern, which was publifhed in 1650, and trandated into Englifh by Mr. Evelyn, with additions. Fr, Blondel, diredur ot the Royal Academy of Painting, 6cc. in 1698, gave a courfe of Architedure in French, which was a colledion from all the celebra- ted writers upon the fubjed of the orders, Sec. Nich Goldman has alfo done infinite fervice, by reducing the rules and orders ot Archit dur to a further degree of perfection, and fhewing how they may be eafily deli- neated, by means of certain infi:ruments invented by him. 1 his trea- tife wa; publifhed in Latin and fligh Dutch in 1661. Alfo, Sir Henry Wotton haS laid down the elements of Architedure, which have been H reduced 26 ARC reducecJ by Stnfmius and Wolfius, fo' certain roTfes and demonftrations. And, by thefe gradations, Architedure has been brought to d matheitia- tical art; by the firft in his Mathefis Juvenelis ; and by the iecdnd, in his Elementa Mathefeos, torn. ii. an. 1715. "'"-4 Military ARCHITECTURE, is the art ct ftrengthening and fortifying places, to fcreen and defend thttn from the infults of enemies, and the violence of Arms..

Of this kind is the celebrated pontifical flair-cafe of the Vatican, built in the time of Pope Alexander VII. by the cavalier Bernini. Coiinterjeit Architecture ; that which confifts of projedures, paint- ed either in black or white, or Colours after the manner of marble; as may be feen performed in the facades and palaces in Italy, and in the pa- villions of Marli. This painting is done infrefco, upon plaiftered walls, and in oil on ftone walls. Alfo, under the title of Counterfeit Architect tnre, is to be comprehended, that which may be alfo called fcene-work, /. e. what is painted on flight boards, or wOoden planks, on which co- lumns, pilafters, and other parts of building, ftem to ftand out in relievo ; the whole being coloured, in imitation of various marbles, metal, &;c. ferving for the decorations of theatres, £cc. Architrave, of i^'/ix;'' chief, zn<^trabs, L. a beam, is that part of a column, or order of columns, which lies immediately upon the capital ; the Architrave is the loweft member of the frize, and even of the whole entablature. The architrave is fuppcifed to rqpreient the principal beam in timber buildings; from whence it takes its name, as above. It is how- ever objected by fome, that they do not perfecftly underftand what is meant by the principal beam of a building; becaufe they do not luppcle it can properly be applied to all buildings, but to fome peculiar kinds, fuch as are called Porticos, Piazzas, and Cloifters ; by which are ufually under- ftood long galleries, or walking places, whofe roofs are fupported by co- lumns or pillars, at leafl, on one fide, which have not arches arifing from them, to fupport the fuperincumbent part of the fabrick ; but have a beam refling or lying upon the tops of the columns, by which the fupe- rior part of the edifice is fupported ; for which reafon 't is probably cal- led the principal beam. Inoced, according to Mr. Perrault's definition, it is the firlf member of the entc^blamcnt, being that which bears upon the column, and is made fometimcs ot a fingle iummer, as appears in the ARC r; he mofl ancient buildings ; and fometimes of feveral haunches, as fre- quently feen in the works of the moderns. Architrave is alfo fometimes called the reafon-piece or mafler-beam, in timber buildings -, as porticos> cloiflers, &c. In chimnits it is called the mantle-pieces, and over the jaumbs of doors, and lintels of windows, hyperthyron. Architrave doors, are thofe which have an architrave on the jaumbs, and over the door, upon the cap-piece, if ftreight, er upon the arch, if the top be curved. Archvrave ivindcivs, of timber, are ufually an ogee, railed out of the folid timber, with a lift over it j though It metimes the mouldings are , flruck, ind la'd en, and fometimes cut in britk. 'J he upper fatio is cal- led the header, or heading Architrave. Architcfts take great latitude as to Architraves, fome ufing more members than others, and many ot them having two or three forms of Architraves. Sometim.es tbty are according to one of the five orders of Architcdure, and fometimes they are accord- ing to the fancy of the workman. Some, for an Architrave round a door, have put firft a fmall he.d next the dcor, then a broad p'inth, or fatio, and above that an ogee ?ncl lirt. There are Architraves ot ftone and brick, as well as of timber. Brick Architraves are ufually, cut in the length of a brick, and fometimes in the length of a brick and a half, and then every other courfe alternately confifts of the breadth of two bricks j the upper one, on which the ogee is cut, and part of the upper fatio, they call header, or heading Architrave ; and the breadth or head of bricks, on which tl>e lower fatio, and part of the upper one is cut, they call a jack Architrave of ilone. Architraves are diftinguiihed into five kinds, viz* Tufcan, Doric, Ionic, Corinthian, and Compofite, according to the five orders of columns. Of the parts, or members of Architraves : ihefe are more numerous than the kind', becaufe there are two different iorts of Architraves to fome of the orders; and what greatly increi>fes the number is, that fome authors differ from others in the form of the fame orders. The 1 ufcan Architrave, according to Vitruvius, ought to be half a mode, or M. in height. This general member he has defcribed in twa forms : the firft confifts of three parts or members, viz. two fatios and a cymatium, and is thus divided : the whole height is divided into fix parts ^ which are divided after this manner, viz. the uppcmioft fixth part is the cymatium j which being lubdivided into three, the upper is to be the fillet, and the two lower parts the ogee. The five grand divifions which remain, are to be divided into nine parts, five ot which are to be the up- per fatio, and the other four the lower one. His fecond form, confifting of but three members, or parts, is as follows, viz. a large plinth or plan- chier, a cafement and a large fillet, and is fubdivided as follows : the whole height is divided into fix ; and the upper part is for the fillet ^which projedls in Iquare beyond the plinth; the fifth partis for thecafement, which lifes fiom the plane of the plinth, and ends in a quadrant at the lower cornels ^8 ARC corner of the fillet) the other four parts remaining are for the plinth, or planchier, or Fatio. Palladio has alio two diftincfl forms for the Tufcan Architrave : the firfl: confifts of two fatios and a lift : the lower fatio is twelve and a half M, high, the upper fatio is feventeen and a half M. ending with a quadrantal cafement, rifing with its plain, and ending with the loweft corner of the lift; the lift is five M. high; and fo the whole height of the Architrave is thirty-five M. His fecond Architrave is only a plain fatio of thirty-five M. high. Scamozzi, according to his delinea- tion, makes the Tufcan Architrave thirty-one and a half M. high; which he divides into fjur parts, or members, viz. two fatios, a lift, and a plinth. He makes his firft fatio ten M. his fecond fixteen and a half M. his lift one and a half M. and his plinth three and a half M. all which make thirty-one, one-third M. Though, according to this verbal ac- count, he fays, it muft be thirty-two and a half M, except it be a typo- graphical error. Vignola defcribes the architrave with the fame parts, height, and form, with Vitriivius's fecond. The Doric Architrave. This Architrave, according to Vitruvius, is half an M. in altitude, which he delineates in two forms : the firft he di- vides into feven parts ; the uppermoft of which is the taenia ; the other fix parts which remain, he makes a fafcia under the taenia, and places drops, whofe height are one-feventh of the Architrave : a fourth of this feventh is the fillet, to which the drops hang; the diops are in number fix; placed under, and of the fame breadth with the triglyphs. His fecond figure of his Architrave confifts of the fame members with the firft, and the whole height is equal to the firft. But he divides the altitudes only into fix parts j the upper one of which is his taenia, and the other five the fafcia ; the up- permoft of which is the altitude of his drops, which have a lift, which is one quarter of their height. Palladio makes this Architrave with the fame altitude with Vitruvius, but of a different form ; for he makes it to confift of three parts or members, viz. two fafcias and a taenia : he divides the ■whole altitude into fix parts, one of which, being five M. he afiigns for the guttae, drops, or bells, and the jiftella of the diops is one-fifth of the wiiole height, and one-third M. and the drops two and two-thirds M, the taenia above the drops (or rather of the Architrave) he alfo makes four and a half M. and tlie prima ^or upper) fafcia, fourteen one-half M. and the fecunda (or lower) eleven M. in all thirty M. which is the whole alti- tude. Scamozzi (according to the portraiture of this Architrave) makes it thirty -five M. in altitude ; and he makes this grand member to compre- hend three petty members, viz. two fafcias and a lift; the dimenfions of which are, beginning at the top, and lo defcendingj the lift he makes five M. the upper fa'cia eighteen M. and the lower one twelve M. in all thirty- five M. divides the drops or bellb^thus : he detignt. the lift above to be one- half M. and the bells or drops four oiie-halt M. fo that the whole height is fix M. Vignola makes this Architrave thirty M. in altitude, the lame as Vi- truvius ARC 29 truvius and Palladlo ; both which he alfo imitates in the leflTer member j for he has two diftindl forms ; one refembhng that of Vitruvius, which contains two members or parts, the one a htl:, the other a fafcia ; his other form is Hke that of Palladio, comprehending three petty mem- bers, viz. one tsnia, and two fatios. The Ionic Architrave : according to Vitruvius's order, this grand mem- ber ought to be half an M. in height. He defcrihes two forms of Archi- traves in the Ionic order, viz. one for the Ionic column, without a pe- deftal ; and the other with apedeflal. He compofes that without a pe- deftal of four minuter parts, viz. three fafcias, and a cymatium ; which is divided as toUows : he divides the whole altitude into feven parts, the uppermost of which he allots to the cymatium, which he fubdivides into three parts j the uppermolt of which is for thsiifl:, and the two remain- ing for the ogee. The other fix remaining parts are divided into twelve ; five of which he makes ti.e upper fafcia, four of the middle one, and three the lovveft. The other for the Ionic column, with a pedeftal, he proportions as follows, viz. he reckons the whole altitude of the Archi- trave, freeze and cornirti, to be two mod. which are divided into ten parts ; three of which are for the Architrave, (which is thirty-fix M.) which he diflinguifhes into fix minuter parts, or members ; which he names as follows, (beginning at the top, and lo defcending) viz. a fillet, a cima, a thorus, and three fafcias ; all which fmaller me:nbcrs he thus finds, viz. firfi: he divides the whole altitude into fix equal pirts ; the up- permoft of which parts he fubdivides into four parts, the highelt of thele four is for the fillet, the two next of the four are allotted to the cima, and the fourth, that remains, is for the thorus. The five grand divifions which remain are fubdivided into twelve, which arediftributed as follows, viz. five for the upper, four for the middle, and three for the lower tal- cia. Palladio afiigns thirty-four M. for the height of this Architrave. According to.his Icheme of this member, it is compofed of feven parts, viz. a lifi:, a cima, three fafcias, and two allragals ; which are propor- tioned as follows : to the lifi: (which is above the cima,) he allots two three-tenths M. to the cima, four three-fifths M. to the upper fafcia, he allows ten one-eighth M. to the aflragal, at its foot, one-third M. the middle fafcia is to contain (even fifty-two fixiictiis ; and tiie aflragal at its foot one-third xVl. to the lower fafcia he aliigns fix nine- tenths M. All which being added together, amount to thirty-four one half M. Scamozzi makes the Ionic Architrave thirty-five M. high, and of the fame form with that of the fecond of Vitruvius, confiiling of fix- parts, viz. a liil, cima, artragal, (cr thorus) and three fafcias j which he pro- portions as follows : he allots two one-half M. to the lifi, to the cima four, to the thorus two, to the upper fafcia eleven one-half, to the mid- dle one eight one-half, and to the lower one fix one-half. Vignola nl- 1 low* 30 ARC lows thirty-.feven one-half to the Tonic Architrave in altitude , and as to the form, it is niuch the fame with that of \''itruviu5's firil: order. The Corinthian Architrave, according to Vitruvius, ought to be half a mod. in height; but it is to be obferved, that this is for the Corinthian column without a pedeflal. This member he divides into kven parts, of which the uppermoft is the cymatium; the fix remaining parts he divides into twelve, of which he allots five to the upper fafcia, aUb allowing one-r eighth of this fafcia for a head at its foot, and makes the lower fafcia of "the three remaining parts. The Architrave for the Corinthian order wih a pedellal, according to Vitruvius, is allowed a greater altitude than that withoutj confifting of the fame members, both as to number and form with the former Architrave, but differing in dinienfions. The whole al- titude of the Architrave ought to be one quarter of the altitude of the column, nearly to two-eighths of the body of the column below, which is ■ to forty-one half M. This altitude he divides into {even equal partF, and makes a cymatium at the uppermoft of thefe feven, and divides the fix that remain into twelve equal divilions ; of which, five he allots to the upper fafcia, four to the middle, and three to the lower one. He fubdivJdes the upper and middle fafcia, each into eight parts, and allows one of thefe eighths for a bead at the foot of each of thefe facias. Palla- dio makes this Architrave to contain eight parts, viz. one lift, one cima, three beads, and three fafcias, the height of all which he allows to be thirty-fix M. Which are thus fubdivided, viz. to the lift, (or upper mem- ber) he allows two three-quarters M. the next in order is a cima, and the next in order is two M . high, at the foot of which is a beid; after this is the upper fafcia, its bead at its foot, both which contain about thir- teen one-half M. After this is the middle of the fafcia, and its bead at its foot, which contain eight one-eighth M. and lafl of all, the lower fifcia, which is fix one-quarter M. in height, Scamozzi makes the whole altitude of this Architrave to be forty M. which he fub- divides into nine fmall members, (beginning at the top, and defcend- inr^) a lift of two M. a cafement three one-quarter M. and an ogee of two three-quarters, a bead of one one-half M. a fafcia of twelve M. and its bead of two M. the middle fafcia eight one-half M. and its bead one three-fifths M. and the lower fafcia fix one-half M. which being all added together, make forty M. Vignola makes the Corinthian Archi- trave forty-five M. in height, and fubdivides it into eight fmalkr mem- bers, as Palladio does, viz. a lift, a cima, three beads, and three fafcias. The Compofite Architrave. Vitruvius makes the Architrave of this column, and freeze, and cornice ail of an equal height, viz. each or which is equal in height to the diameter of the column abov?, juft under the capital, which is ten-twelfths of a mod. fifty M. This Architrave he divides into fix parts, one of which is for the cymatium, and its boultin ARC 31 boultin under It : tills upper fixth part he divides Into four, and allows one of thefefojr for the fillet above the cima, and the two next for the cima itfejf j and appoints the fourth, that remains, for the fmall boultin under the cima ; and fubdivides the other five grand divifions into twelve minuter parts, afhgning five of them for the upper fafcia, four for ths middle one,' and three for the lower ; and alfo fubdivides the middle faf- cias each ir.to eight parts, allowing one of thefe eights for a bead at the foot of each of thefe fafclas. Palladio makes this Architrave forty-five M. in height, and diftributes them into (even particular minuter members (beginning at the top, and fo defcending ;j firfV, he allows two one-eighth M. tothelifi^, four one eighth to the cafement, to the ogee nine one-quar- ler, to the bead one one-quarter, to the upper fafcia fifteen M. two one-quar- ter to the ogee at. its foot, and eleven M. to the lower fafcia. Scamozzi makes this Architrave forty M. in height, which he dillributes among thefe eight following members, viz. (defcending :) firft, a lift of two M. fecond- ]y, an ogee of four biVt-half M. thirdly, an aftragal of twp M. fourthly, the upper fafcia of eleven three-quarters M. fifthly, a bead at its foot of two one-quarter M. fixthly, ihe middle fufcla of eight one-half M. le- venthly, at its foot, one-rhalfM. eighthly, the lower fafcia of fix one- half. Vignola makes this Architrave forty-five M. in height, which he divides into {even members, a lift, a cafement, a boultin, a fillet, a fafcia, a h^id, and a fafcia. . . ,_. ,''Meafuring of Architraves.:, Architraves In buildings (either of brick, or flone) are ufually done by the foot lineal ; and therefore, having taken the length in fact, you have, atlfo the content the fame time. Architraves,, fays Mr. Skaife, are taken , (or inealiired) with a firing over the top, and down both jambs for the Jength ;' and girted round the face and back to the wall for the breadth.

The Ionic Arcliitrave is divided Into nine, giving one and three-fourths to the firfl face, two and a half to the fecond, and three to the third ; one and one-fourtli to the ogee, and one half part to the fillet; the pro- jedion of the fecorid.and third faces have a quarter of a part each, and the whole two of thefe parts. The Corinthian Architrave is divided into nine, giving one and a half to the firft face, one-fpurth to the fmall bead, two to the fecond face, three- fourthiS to tlie fmall ogee, two and a half to the third face, half a part to tile bead, one to the ogee, and half a part to the fillet ; the projection of the fecond face hath one-fourth of a part, the third face one ol' thefe parts, and the whole two.

Area, in Architedlure, any plain furface whereon we walk, &c. Area, in Geometry, the fuperfici:tl content of any figure. Thus if a figure^ exempli gratia, a field be in the form of a fquare, and its fide be thirty feet long, its area is faid to be goo fqusre feet, or it contains 900 little fquares, each a foot every way. Arithmetic, the art or fcierice of computing by numbers. We have very little intelligence with regard to the invention of this inellimable fcience. Some attribute it to Seth, others to Noah, and the Turks to Enoch, whom they call Edris. Many imagine it had its rife with the introdudlion of commerce, and confequently fix its epocha with that of the Tyrians, who did not begin to fiourifh till about a thoufand years after the flood. Jofephus tells us, that Abraham taught the PIgyptians Arithmetic during the time of his fojourning in their country : though Pliny and Strabo fay, that the inundations of the Nile gave occafion to their inventing both Arithmetic and Geometry. ' It is however certain, both thefe fciences were held in the higheft veneration, and committed to the care of their prieAs, who founded their theology on them. The Greeks owed their knowledge in Arithmetic to the Egyptians j and Pythagoras built his philufophical fyftem upon numbers, affirming, that the nature of numbers extends through the whole univerle, and that the knowledge of numbers is the knowledge of the Deity. The antient Arithmetic, however, fell far fliort of the modern ; their notation was very imper- fect, and confequently the operations abftrufe and tedious. They wanted the cypher, or a character that of itlclf fignifies nothiog, to fill up a place, and change the value of their numbers in a decuple progrelTion, their feries extending only to nine. We owe our prefent notation to the genius of the eaftern nations, and received it from the Arabians, who learned it from the Indians. But when, or by whom it was invented, cannot be known. It was known in Europe before the year looo, and in Britain 1 1 50. The oldeii treatife extant on the theory of Arithimetic, is 7 th, 8th and 9th books of Euclid's Elements j where he has delivered the do(flrine of proportion, and that of the prime and com- pofite numbers. After the Arabian notation was known in Europe, we find many writers both upon the theoiy and practice ; and as learning advanced, fo did the knowledge of numbers, which by degrees received the grcateit improvements. The fundamental rules of Arithmetic are four, namely, addition, inh-t ftrat'tio.n, multiplication, and divifion. But befides theie, theie are other rules ASH 33 rules contrived for facilitating computations of every kind ; as the rule of proportion, rule of three, or golden rule, the rules of fellowfhip, barter, exchange, intereft, extraiftion of roots, &c. Injirumental Arithmetic, is that where the common rules are per- formed by means of inflruments, contrived for eafe and expedition, as by the lines on a Carpenter's rule, a fedor, 6cc. Ash, fraxinus, in botany, a genus of trees. Next to the oak itfelf, it is reckoned one of the rriofl ufeful forts of timber we have, ferving for fo many ufes for the carpenter, cooper, &c. and, like the elm, is good for mortoifes, tenons, &c. it hath pinnated leaves, which moftly end in an odd lobe: the male flowers, which grow at a remote diflance from the fruit, have no petals, but confift in nuany flamina ; the ovary becomes a feed- veffel, containing one feed at the bottom, {haped like a bird's tongue. There are fix fpecies of this tree j all which may be propagated by bud- ding them into comnioa Afli ; upon which they will all take very well, and become hardier than upon their owii flock : but thefe budded trees never grow fo large as thofe which are raifed from feeds ; nor will the ftock and bud keep pace in their growth ; fo that there will be a remark- able difference in the fize of the flem, and above the place where they are budded : but few of thefe foreign kinds have yet arrived at an age to pro- duce feeds in England, the nurfery gardeners having been obliged to pro- pagate thefe forts by budding and grafting. The common Afli is propagated by fowing the keys in Ocflober or No- vember, en a bed of frefh earth, which fliould be well dug, and cleanfed, from roots and noxious weeds. A fmall bed will be fufhcient to rail'e a great quantity of thele trees. The feeds Qiould be fown pretty thick, and covered about half an inch thick with earth. Thefe feeds many times continue until the fecond fpring before they come up ; you fliould, there- fore, let the bed remain undillurbed, and keep it clean from weeds. When your plants come up, you muft alio keep them very clear from weeds, and if the leafbn fliould prove very dry, if you give them now and then a little water, it will greatly promote their growth. In this bed they (hould remain no more than the autumn following, provided they have grown well ; at which time you fliould prepare a nurfery, which fliould be well dug and cleared as before ; then with your fpade loofen the roots of your plants before you draw them up, otherwife you will endan- ger the breaking of them. When you have drawn them out of the ground, ihorten the downright tap root, but do not cut off any of the lateral fibres ^ then, having prepared your ground, plant them in rows, three feet dif- tance, row from row, and a foot atunder in the rovv'S, clofing the earth to the rools with your feet. In this nurfery they may remain two or three ye^rs, obferving to keep them clear from weeds, as alio to trim up the fide branches every winter, and dig the ground between the rows; after K which 34 ASH which time you may remove them where they are to remain for good. This tree will grow upon almoft any Toil; but the better the foil is, the more the tree will incrdfe in bulk. Notwithftanding which, it Onould not, by anv means^ he planted too near the other trees or plants ; for it will exhauft'all the goodnefs of the foil from them ; and the (hade of this tree i§ malignant to moil: other plants. The diilance they fliould be planted is eight feet fquare ; and, after they have been planted one year, you may cut down eveiy other tree, choofing fuch of them as are crooked, within fix or eight inches of the ground j this will caufe them to make many ftrong, vigorous fhoots ; which, in fcven or eight years time, will be fit for arbour poles, or to make hoops ; and the other ftraight trees may be fuffered to grow for other timber; the number of which trets may be leflened, as they increafe in bulk, leaving flill the moft promifing ones to grow for larger timber. If a wood of thefe trees is rightly managed, it will turn greatly to the advantage of its owner, for by the underwood, which will be fit to cut every ftven or eight years, for the ufes abovemen- tioned, there will be a continual income, more than fufficient to pay the rent of the ground, and all other charges ; and ftill there will be a flock preferved for timber, which, in a few years, will be worth forty or fifty (billings per tree. This timber is of excellent ufe not only to the carpenters but to the wheel-wrighis, and cart-wrights, for ploughs, axle-trees, wheel-rings, harrows, bulls, oars, blocks for pullies, and many other purpofes. The beft feafon for falling of thefe trees is from November to February; for if it be done too early In autumn, or too late in the fpring, the timber will be fubjed: to be infefled with worms, and other inleds ; but, for lopp'ng of pollards, the fpnng is preferable for all foft woods. Ashlar, a term ufed by builders, by which they mean common free- flones, as they come out of the quarry, of different lengths and thick- neffes. As to the goodnefs of the ftones, either for their durablenefs or laroenefs: their durablenefs is only to be known by experience, for at the firil opening of a new quarry it is uncertain how the (tones may prove: for fome ftones, when they are firft taken out ot the qunrry, are very foft and fiiable, and will moulder to fand by being expo(ed to the air only a few years : whereas others of thofe foft Ifones, will be indurated or har- dened, by being expofed to the air. Tho(c ftones which come hard out of the quarry, arc generally durable, being of a more firm and folid con- liftence. As to their largeneis, I need only obferve, that large ftones muft certainly be better, and make firmer work than fmali ones j which are only fit for filling work in thick walls; or to be ufed in thofe places where the country affords no better.

Assemblage, the joining or uniting of feveral things together, alfo the things fo joined or united; of which aflemblages, there are various kinds and forms ufed by joiners, as with mortoifes, tenons, dove-tails, &;c. Assemblage of Orders. M. Le Clerc fays, when two columns are placed over one another, they muft be of different orders, the flronger always to fupport the weaker. For infl^ance, i. The Doric may be placed over the Tufcan, the Ionic over the Doric, the Roman over the Ionic, the Spanidi over the Roman, the Corinthian over the Spanifli. 2. That the upper order fhould always be lefs maflive than the under, agreeable to the maxim, that xhe. Jircng ought to fupport the weak. 3. That the columns ought to ftand exadlly over each other; fo that their two axis's may be both found in the fame perpendicular. 4 The diflances between the lower columns, rauft be determined by the intercolumniations of the order, that is, without pedeftals ; and the diftance of the upper columns, by the intercolumniations of the order, with pedeftals, taking care that the firft order be mounted on a pretty high zocle, or an afcent of feveral fteps, to fervc inltead of a continued pedeftal, or foot. He gives a pedeftal to the upper order ; becaufe being confined to the breadth oi the intercolum- niation of the lower order, its columns, by this means, are rendered fmaller, infomuch, that the diame;er of their bafe does not exceed that of the top of the under column j which, in his opinion, is a rule not to be difpenfed with. He remarks, that Vitruvius will not allow the upper order more than three quarters of the height of the under. But if this redudlion were followed, the columns would be too fmall, and conle- quently too far afunder, with refptct to ihcir height, if placed one over another. In order to find tlie mod. of an order that is to be placed over another, he propofes, for inftance, to place the Jonic over the Doric ; and advifes. To confider, firfl, that in the Doric order, without a pedeftal, which is to give the meafures of that firft order, that the columns are placed at the diilanceof eleven M. from each other, in portico's. That in the Ionic 36 ASS Ionic order with a pedeftal, the columns are fifteen M. a-part ; and that to place this order upon the Doric, you muft divide the intercolumn, or its equal, into fifteen equal parts j one of which fifteen will be the M. for raihng the Ionic order, with its pedeftal. He likewifc obferves, that when two porticos ?re placed over each other, the higher ought to be re- gulated by the lower : he means, that the width of the upper arch Oiould be made equal to that of the under ; it being proper, that the two arches fhould have the fame width. On fuch an occafion, the lower arch mav be made ten or twelve minutes narrower than ufual, that the width of the upper arch may be better proportioned. When columns are to be without porticos, he fays, there need be only four triglyphs made between the Doric columns, that is, an interval of eight mod. four minutes, which are equivalent to twelve M. in the Ionic, as appears by the rule of proportion ; and that the fame thing may be obferved of coupled columns. The Roman order, he obferves, does' not match perfedlly well with the Ionic; becaufe its capital is higher, with refpccl to its column, than the Ionic capital, with refpedl to the Ionic column ; and becaufe the denticles of the Ionic appear lomewhat weak underneath the modillions of the Roman. However, the Roman order, being in this place lefs than the Ionic, the difproportion between their capitals, becomes lefs fenfible, as well as that between the denticles of the one and the modillions of the other. To find the M. for raifing a Corinthian column over a Spanifli order he fays. It is evident, that the modillions of the upper order mufl: be the fame in number with thole of the under, in order to have them exadly ever one another. Now the inter-modillions of the Corinthian order contain- ing juft forty minutes, where the column has no pedeftal, thefe iorty mi- nutes muft be multiplied by the number of modillions, which being eleven, the produdl will be four hundred and forty j which being divided by thirty, the mod. the quotient will be fourteen M. twenty minutes ; whicli is the divifion of the fcale for raifiiig the Corinihian order. He oblerves, that there is a difficulty in placing three orders over each other, which confifls in this; that the fecond order having a pedeftal, the columns of the third become a little tco large, at the bottom; th' ugh fo very little, that the eye can hardly perceive it. But this inconveniency, however, may be remedied, by taking the excefs away imperceptibly, wholly from the bafe of the column. This will indeed occafion a little fwelling ; but t"hat will do no prejudice. Again, he is of opinion, it would not be pro- ptr to undertake the placing of more than three orders of columns over one another. For, beijdes that in the fourth order, the columns would be too far afup.dcr ; in refpet^ to their height, it ought likewife to be con- fid ered. ATT 37 fidered, that four columns raifed over one another, cannot be very ftrong: indeed, the firft may have a Ruflic, whereon it is railed, and which may ferve it as a foot. Astragal, in architedlure, a little round moulding, in the form of a ring, or bracelet, fcrving as an ornament at the tops and battoms of co- lumns. The Aftragal is alfo fometimes ufed to feparate the fafcIiE of the archi- trave ; in which cafe it is wrought in chaplets, or beads and berries. It is likewife ufed both above and below the lifts, adjoining immedi- ately to the edge or fquare of the pedeftal. M. le Clerc obfervss, that the Aftragal of a column ought always to- be plain, excepting in the Ionic order, where the Aftragal of the Ihaft is converted into a chaplet of pearls and olives for the capital. Aftragal or Baguette, has the figure of a ftaff, when it is joined to a fillet J the height of which fillet, M. Lc Clerc divides into three parts; two of which he gives to the Aftragal. And this rule, he lays, he ob- fervps upon all occafions. This Aftragal is fometimes carved with pearls and olives, which the French call Pater-nofters. Asymptotes, are properly ftraight lines, which approach nearer and nearer to the curve, they are faid to be Afymptotes of; but if they and their curves are indefinitely continued, they will never meet. Afymptotes are alfo tangents to their curves, at an infinite diftance. And two curves are faid to h^Afymptotical, when they continually approach to each other, and if indefinitely continued do not meet. Atlasses, in archited:ure, a name given to thofe figures, or half figures of men, fo frequently made ufe of inftead of columns orpilaftcrs, to fupport any member in architecture, as a balcony, or the like. Thcfe are alfo called Telamone. Attic, in its general fenfe, fignifies fomething relating to Attica, or the city of Athens. It is ufed in architecture for a kind of building, wherein there is no roof or covering to be itfa ; being thus called becaufe ufual at Athens. Attic, cr Attic Order, is a fort of little order raifed upon a larger one, byway of crowning, or tofinilh the building. It is alio fometimes ufed for the conveniency of having a wardrobe, &c and, inftead of regular columns, has only pilafters of a particular form. Attic Order, according to M. Le Clerc, is a kind of rich pedeftal. Some architects give it the feveral capitals of all the orders of columns ; but, he fays the Ionic, Roman, and Corinthian, do not in the leaft be- come it. It is his opinion, that it is beft only to diftinguifh the capitals by a difference in their mouldings; which may be made more or lefs fimple, and more or lets delicate, according to the relation they are to bear to the architecture underneath. L The 38 A X I The name Aflic, is alfo given to a whole ftory, into which this order enters ; this little order being always found over another ihat is greater. The pcdeftal, cr falfe pilafter, he obferves, ought always to have the fame breadth with the column or pilafter underneath ; and its height may be equal to a third, or even half of the lame column or pilafter, fay which it is fupported. jlttk of a roof, is a kind of a parapet to a terras, platform, &c. Aitic continued, that which encompaffes the whole pourtour of a build- ing, without any kind of interruption, following all the jets, the returns of the pavilions, 6cc. • Attic i/itcrpofeJ, is one fituate between two tall ftones, frequently adorned with columns or pilafters. Attic Base, a peculiar kind of Bafe, ufed in the Ionic order by an- cient architects j and alfo by Palladio, and other moderns, in the Doric. It is the moft beautiful of all the Bafes.

Attributes, in fculpture, &;c. fymbols added to feveral figures, to denote their peculiar otfice and character j as a club is the attrioute of Hercules; a trident, of Neptune; a palm, of Vidtory ; the eagle, of Jupiter; a peacock, of Juno, &c. Aureola, a kind of crown of glory, given by ftatuaries, Sec. to iaints, martyrs, 6cc. as a mark of the viclory they have obtained. Axis, in its primary fignification, fignifics a line, or long piece of iron or wood, parting through the center of a fphere, which is moveable upon the fame. Spiral Axis, in archite at, the diflance. of a fourth of an inch from the circumference of the wheel C D (which is the fame as if a new wheel was added of half an inch more diameter); then a power equal to no more than 4J of a pound, will keep the weight in equili- brio, and raife it, if its intenfity be increafed ever fo little. B BACK NAILS, a kind of nails made with flat llianks, fo as to hold fafl without opening the grain of the wood, ufed in nailing guts to- gether, for faving water under the eaves of a houfe; or by back- makers, in nailing of boards together for coolers, or any veflels made of planks or boards for containing liquors. Bagnio, an Italian word, fignifying a bath : we ufe it for a houfe with conveniency for bathing, cupping, fweating, and otherwife clean- fino- the body, and very frequently for worfe purpofes. Bake-House, a room or office, or an apartment belonging to noble buildings, and other private buildings in which an oven is built. As to the pofition, it ought, according to the rules laid down by Sir Henry Wotton, to be placed on the fouth-fide of any building. Baguette, in architcdure, a little round moulding, lefs than an aftragal ; it is fcmetimes carved and enriched with foliages, pearls, rib- bons, laurels, &c. Though, according to M. Le Clerc, when a Ba- guette is enriched with ornaments, its name is changed, and it is called a chaplet. Baguette is alfo a term ufed by the carpenters for a kind of aftra- gal or hip-moulding, by which is underftood the outward angle or the hips or corners of a roof; which, in fquare frames, where the roof is three quarters pitch, contains an angle of one hundred and fixteen degrees, and twelve minutes. Balance, B A L 41 Balance, or Ballance, Libra, one of the fix fimple powers in mechanics, principally ufed in determining the difference of weights in heavy bodies, and confequently their maffes or quantities of matter. The balance is of two kinds, the ancient and the modern. The ancient or Roman, called alfo the flatera Romana, or fteel-yard, confifls of a lever or beam, moveable on a center, and fufpended near one of its ext^^emi- ties : the bodies to be weighed are applied on one fide of the center, and their weight is fliewn by the divifion marked on the beam, where the weight, which is moveable along the lever, keeps the fteel-yard in equili- brio. This balance is ftill frequently ufed in weighing heavy articles. The modern balance now generally ufed confifts of a lever or beam fuf- pended exadlly in the middle, having fcales hung to each extremity. •• The lever is called the jurgum or beam, and the two moieties thereof on each fide of the axis, the brachiaor arms. The line on which the beam turns, or which divides its brachia, is called the axis ; and when con- fidered with regard to the length of the brachia, is efteemed a point only* and called the center of the balance : the handle whereby it is held, or by which the whole apparatus is fufpended, is called trutina, and the flender part perpendicular to the beam, whereby either the equilibrium, or preponderancy of bodies is indicated, is called the tongue of the balance. Balcon y a projedlure beyond the naked part of a wall or building, fupported by pillars or confoles, and encompaffed with a baluftrade. Or it is a kind of open gallery for people to ftand in to behold any public (hew, as pageants, cavalcades, public entries of embafTadqrs, &c. in cities J or for taking the air, &c. This jutty or projeiftive building is ulually placed in the middle of a front of a houfe, or public hall, &c. if there be but one; and is ufually level with the firft floor, up one pair of ftairs. Some of thefe are made with wood, and others with iron j wooden balconies confift of rails and baluftcrs, and fo fome- times do thofe of iron; but at other times they are made of ca(} iron, of various figures in femi-relief; and fome again, of wrought iron in crail'd work, or flourishes in different forms, according to the fancy of the workman, 6cc. It may be proper here to take notice of what Sir Henry Wotten fays concerning all in-lets and out-lets, fuch as balconies, window?, &c. that they ought not to approach too near the corner of walls? it being an e(- fential error, to weaken that part which is to ftrengthen all the reft. This, he fays, is a precept well recorded, but is ill pradlifed, even by the Italians themfelves ; particularly at Venice? where he had obferved divers Pergoli, or MaucJna, (as they fecm to be called by Vitruvius,) which are certain baluftraded out-flandings, made for ftanding in, to fatiify the curioljty M of; 42 B A L of the fight, very dangeroufly fet forth upon the very point itfdf of '-the murnl angle. - '-!'jv:. - •. fi" .0 M. Le Clerc, favs, the parts of a balcony are the terras/ the balgftrade that indole? ir, and the confoles which fupport it: or, to explain hiihfelf more accuratelv, a balcony is a piece of architecflure raifen in t!ie air', inclofed with a baluflrade, and fupported by a little entablature, whereof the cornice, or uopernioft part, makes a terras; the frieze and architrave being only continued at the bottom and fides ; and the whole fealc-ony fur-' ther fupported by confoles. The frieze is made with a little'fweep, that the zocle of the pcdeftM above may hot appear ill lupported j and that the conlole coming to ccntradl, or fhraighten itlelf at the bottom, may do it the more gracefully, wi'hout which, it would appear foo heavy. The height of the confoles may be equal to the proj'ectu-rlf r but it will be an addition both to the beauty and ftrength of the worfc,' If' they are 'made higher. - ■ ^"-' ■ A balcony may be continued quite through the ftcade of a building by adding confoles, from ipace to fpace j to be difpofed between the windows, which will be underneath. He is of opinion, thut iron balconies will do much better than thofe of flone, as being lightfer, and lefs fuhjed: to de- cay ; which, if gilt, will be exceedingly magnificent, and a vtry proper 01 nament for a palace. According to the modern mode of building, fmall balconies of iron are made before each window in the firft floor ; and the apertures, and confe- quently the windows, are begun on a level with the floor, and yet carried up to the fame height, as if they had began in the ufual manner. Baldachin, oi Baldachino, Ital. Ba'dagium, Fr. a piece of architedure- in the form of a canopy, fupported with columns, lerving as a crown or covering to an altar. It properly fignifies a canopy carried over tlie boil: in Roman catholic countries. Some aJfo give the name of Badalchin to a fhcll over the front of a houfe. Balks, poles or rafters, over out-houfes or barns ; and among brick- layers, great beams, fuch as are ufed in making fcaffolds; this term is alfo applied to great pieces of timber coming from beyond the feas by floats. Ballon, in Architefture a French term, uled to fignify the round globe on the top of a peer, or pillar. Balustrade, aconneiftion of a number of baluflers ufed for defence or ornament, on balconies, terraces, and the like, and round altars. The ba- lufters are of iron, wood, ftone, or other materials, and the Baluftrade, when finely executed, has an elegant appearance. We have ot late, in fome handfome buildings, miferably lupplicd the place of the antient Baluftrade by Chinefe rails. The Balustrade may confift of i or more rows of ba- luflers, and may ferve as a reft in the front of terraces, and as a defence on levels J and it is fometimes ufed, with great propriety and beauty, by way of B A S 43 of reparation between one part of a building and another. The baths a- mong the antients were thus encompafled with rails, and the word expref- fitig that reparation was Baluftrum ; hence comes our word Balullrade ; and balufler for the fingle pillar. Baluster, (vulgarly called banifter) a fmall pillar or pilafter, ferving to fiipport area!, and making, when joined and continued with others, the ba- luttradc we have jiifl: named. The Balufler may be either round or fquare, but it fliould be adorned with mouldings and other decorations, acconiing to the richnefs intended to be given to the baluftrade. Our Balullers of wood are ufually turned, and often very handfome. Band, a term often ufed to exprefs what we more ufually call the face, orfaces, fafcix, of an architrave; but it properly expreffcs any flat and low member, whatever be its place ; if it is not very deep. Bandelet, derived from the French Bandclette, a- little fillet or band, is any little band, or flat moulding, as that which crowns the Doric archi- trave. It is alfo called Tenia, from the Latin Tania, which Vitruvius ules for the fame thing. It is alfo ufed by a'chiteils, to fignify the three parts which compole an architrave. Base, a part placed at the bottom of a column or pihfter, as the capi- tal is at the top. The words fignifies a fupport of any kind, and for any thing i its derivation being from the Latin batis, of which this is the kvfe } but we have appropriated it in a manner to this lower part of column-. The antients, in the early times of architedlure, ufed no Bafes. The Doiic columns, in the temple of Minerva at Athens, have none, but ftand immediately upon the floor of the porch. Columns afterwards came to be fupportcd on fquare pieces called pliiuhs, and after that on pedeftals. When we fee a column, of whatfoever order, on a pedeftal, the Bafe is that part which comes between the top of the pedeftal and the bottom of the rtiift of the column ; when there is no pedeftal, it is the part be- tween the bottom of the column and the plinth ; fome have included the plinth as a part of the Bafe, but it is properly the piece on which the Bafe rtands, as the column ftands upon that. The pedcftal alfo has its Bafe as well as the column and the pilafter. The Bafe of columns is differently formed in the different orders, but in general it is compofed of certain fpires or circles, and was thence in early times called the fpire of a column. Thefe circles were in this cafe fup- pofed to reprefent the folds of a fnake as it lies rolled up ; but tiiey are properly the reprefentations of feveral larger and fmaller rings or circles of iron, with which the trunks of trees, which were the antient columns, were furrounded, to prevent their buriling : thefe were rude and irregular, but the fculptor who imitated them in ftone, found the way to make them elegant. The 44 B A S The Txifcan Bafe confifls only of a fingle torus, or round member upon the plinth ; this is the moft fimple of all. The Doric Bafe has a torus aqd an inverted cima in the colifeum; the Ionic Bafe has a fingle large torus, which is placed over two flenderfcotias, that are feparated by two altragals. The Corinthian Bafe has two torus's, two fcotias, or hollow members, and two aftragals. And the Compofite has a double aftragal in thi- middle. Thefe feveral terms will be explained in their places. We haveobferved, that the Doric had antiently no Bafe; Vitruvius allows none, and other antique buildings befide the Parthenian of Athens might be produced as inflances. Even the Ionic in feme very antient pieces has no Bafe ; fo that we fee what is done in this matter is arbitrary, and has been intro- duced of later time than the period of many buildings of which we have remains ; but this muft not be confidered as an improper deviation from the mofl antient manner, but as an improvement upon it j for the Bafe is a very natural and very beautiful part of every order. We have named the Bafe aopropriated by writers to each order, but there is bsfides thefe five, another called the Attic, or the Atticurgick Bafe, which excels them all in beauty; and was firfl; given to the Doric, and fince to alraofi: every other column. This Bafe confiils of two torus's and a fcotia ; the two tores are of different dimenfions, and the fcotia runs between them. The Ionic Bafe is unnatural, becaufe it is fmaller below than higher up, neither is thatof the Corinthian without its faults : both are greatly infe- rior to the Attic, which is therefore often with great judgment lubdituted in their place. The antients feem to have given the fame, or nearly the fameprojefture to the Bale, in all the orders where we find it in their works. For in- ilance, we fee the fame projedure in the Bafe of the Doric and Corinthian order in the Colifasum, and in that of the Ionic in the temple of Con- cord; and the difference between the greatefl projeiflure of any antique Bafe we know, which is in the arch of Titus, and the leafl, which is ia the Corinthian order in the Colifasum, is very trifling. Basil, among joiners, &:c. the angle to which the edge of an iron tool is ground. To work any foft wood, they ufually make their Bafil twelve degrees, and for hard, eighteen degrees; it having been obferved, the luore acute or thin the Balil is, the better and faioother it cuts ; and the more obtufe, the ftronger and fitter for fervice. Basilic, an ancient palace. Thefe were vaft buildings, confifting of a great hall, with ifles, porticos, tribunes, and tribunal, where the fove- rcigns in perfon adminillered juftice. This is the proper and flridl fenle of the word, according to the Greek ; but the architects have taken the liberty to extend its meaning faither, and Balilic is now uied as c name of any ipacious building, a hall, churcli, or the like. Weftminfler hall is properly in this fenle a Bafilic; but the anlients were more flridt in the B A S 45 the ufeof the word, and would not have called any thing but a royal pa- lace by that name. Any large building for a court of juft ce, and ex- change, or the like, is. now allb called a Bafilic. When BafiHc is ufed as the term for a church, it always means a large and elegant one. Bason, a refervoiror refervatory of water, as the Balon of a jet d'eau, or fountain, the Bafon of a port, bath, &c. which Vitruvius calls Labrum. Basso-Relievo, ,or Bass Relief, a piece of fculpture, wherein the figuies do not projeft far, or ftand out from the ground in their full pro- portion Some authors have diftinguilhed three kinds of Baflb- Relievo. In the firft, the front figures appear almoll with the full Relievo; in the fecond, they p-'ojedl above one half; and in the third confiderably lefs, as in vafes, coins, 6cc. Bastion, in fortification, a large mafs of earth, ufaally faced with fodg, fometimes wiih brick or flone, (landing out from a rampart, of which it is a principal part. < j ■ A Baftion confiifs of two faces and two flanks j the faces Include the angle of the Baftion, and their union forms theoutrnoft, or faliant angle, called alfo the angle of the Baftion j. and the union of the two faces to the two. planks, makes the fide angles, called alio the ftioulders or epau- ]es ; and the union of two other ends of the flanks to the two curtains, makes the angles of the flanks. The great rule in conftrucling a Baftion is, that every part of it may be feen and defended from fome other part : mere angles therefore are not fufiicient ; but flanks and faces are necelTary. The faces muft not be lefs than twenty-four Rhineland perches, nor more than thirty. The flanks of a Baftion, provided they ftand at the fame angle under the line of defence, are fo much the better the longer they are j they muft there- fore ftand at risht angles with the line of defence. At the fame time the difpofition of the flanks make the principal part of fortification, as on them the defence chiefly depends; and it is this that has introduced the various kinds of lortifying. The angle of the Baftion muft exceed fixty degrees, otherwife it will be too fmall to give room for guns, land will either render the line of defence too long, or the flanks too fhort. It muft therefore be either a rig;ht angle, or lome intermediate one be- tween that and fiXty degrees. Solid Bastion, thdt which has the void fpace filled up entirely, and railed to an equ-1 height with the rampart. Void or Hollow Bastion, that which is only furrounded with a rampart and parapet, having the fpace within void or empty. Flat Bastion, a baftion built in, the middle of the curtain, when it is too long to be defended by the Baftioiis at its extremities. Cut Bastion, that whofe point is cut off"' inftead of which it has a re-entering angle, or an angle inwards, with two points outvvacdb ; and N is 46 BAT t. Is ufed, eiiher when the angle would, without fuch a contrivance, be too acute, or when water, or Ibme other impediment, prevents the Baftion from being carried to its full extent* Composed Bastion ; when two fides of the interior polygon are very unequal, which alfo renders the gorges unequal.

Hence, any angle that is not fquarcjjs called a Bevel-angle, whether it be more obtufe, or more acute than a. right-angle: but if it be one half as much as a right-angle, viz. forty-five degrees, then workmen call it a mitre ; they have alfo a term half-mitre, which is an angle that is one quarter of a quadrant or fquare, viz.,,^n angle of twenty-two degrees and a half, they call a half-mitre. .*^ , Binding-Joists, thofe Joifts iji.any floor, into which the trimmers of flair-cafes (or well-holes for the flairs) and chimney-ways are framed.

As a line is formed by the niotion of a point, and a fuperficies by the motion of a line, fo a Body is general by the mo- tion of a fuperficies. ' To bear a Body, with painters. A colour is faid to bear a Body, when it is- of fuch a nature, as is capable of being ground fo fine, and mixing fo entirely with oil, as to feem only a very thick oil of the fame co- lour j and of this nature are white lead and cerufe, lamp-black, Vermil- lion, lake pink, yellow-oker, verdigreafe, indigo, umber, and Spanifh- brown ; blue-bice and red-lead are not quite fo fine ; but yet they may be faid to bear a very good Body. All thefe may be ground fo fine, as to be even like oil itfelf; and then they alfo may be faid tJ work well, fpreading fo fmooth, and covering the Body of what you lay upon it fo entirely, as that no part will remain vifibie where the pencil has gone, if the colour be worked ftiff enough. But, on the contrary, verditers and fmalts, with all the grinding imaginable, will never be well imbodied with the oil, nor work weilj bice and red-lead indeed will hardly grind to an oily firmnefs, nor lie entirely fui oth in the working; yet it may be faid to bear a tolerable Body, becaufe they \v/ll cover fuch work as they are laid upon very well; but luch colours as are faid not to bear a Body, v/ill rea- dily part with the oil, 'wlien laid on the work; fo that when the colour fliall be laid on a piece of work, there will be a fepaiation, the colour in fome parts, and the clear oil in others, except they are tempered extrerne.- ly thick. P Bolts 54 B R, A Bolts cf Iron, for houfe buildings are diftingulflied by ironmongers inJo three kinds, viz. plate, round, and fpring Bolts ; plate and fpring Bolts are ufed for the faftening of doors and windows, and thefe are of different fizes and prices. There are alfo brafs- knobbed Bolts, fhort and long. Bond, a term among workmen j as make good Bond, fignifies that they fhould faften two or more pieces together, either by tenanting, mortifing, or dove-tailing, 6cc. BossAGE, in architecture, a term ufed for any flone that has a projec- ture, and is laid in a place in a building lineal, to be afterwards carved into mouldings, capitals, coats of arms, &c. Bojj'age is alfo that which is otherwife called ruftic work; confifting of flones which feem to advance beyond the naked of a building, by ■ reafon of indentures or channels left in the joinings j thefe are chiefly ufed in the corners of edifices, and thence called ruftic quoins. The ca- vities or indentures are fometimes round, and fometimes frame chained or levelled; fonieiim^s m a diamond form, and fometimes inclofed with a cavetto, and fometimes with a liftel. BouLTiNE, a term ufed by workmen for a moulding, whofe convexity js juft one-fourth of a circle ; being the member next below the plinth in theTufcan and Doric capital. BouTANT, or Argh-Boutant, in architedlure, a flat arch, or part of an arch, abutting againfl the reigns of a vault, to prevent its giving way. A pillar Boutant, a large chain or pile of flone, made to fupport a wall, terrace, or vault. Brack, in building, a piece of timber framed in with bevel joints; the ufe c-f which is to keep the building from Iwerving either way. When tlie Brace is framed into the king- pieces, or principal rafters, it is fome- times called a fl:rut. Brads, among artificers, a fort of nails ufed in building, which have no fpreaaing heads. They are di[i;inguifl:ied by ironmongers, by fix names, as joiners-Biads, flooring-Brads, batten-Brads, bill-Brads, or quarter-heads, &c. Joiners-Brads are ufed for haid wainfcot^ batten- Brads for foft wainfcot; or bill-Brads are ufed when a floor is laid in halle, or for (hallow joifl:s fubjedl to warp. Branches, of ogives, in aichitcdure; the arches of Gothic vaults. Thele arches traverfing from one angle to another diagonally, form a crofs between the other arches, which make the fides of the fquare, of which the arches are diagonals. Brazing, the foldering or joining two pieces of iron together, by means of thin plates of brafs melted between the two pieces to be joined. If the work is very fine, as when the two leaves of broken faws are to be joined B R E 55 joined, it Is covered with beaten borax, moiftened with water, that it may be Incorporated with the brafs duft, which is here added; and the piece is expofed to the fire without touching the coals, till the brafs is obferved to run. Laftly, to braze with a flill greater degree of delicacy, they ufe a folder made of brafs, with a tenth part of tin ; or another one third of brafs, and two-thirds of filver; or borax and rofin ; obferving, in all thefe methods of Brazing, that the pieces be joined clofe through- out ; as the folder holds only in thofe places that touch. To Break in, in architecture, a term ufed by carpenters, when they cut or rather break a hole in brick walls with a ripping chizzel. Brest, a term in architedlure, ufed, by fome, to fignify the fame member in a column, that others call a thorus. Breast- Summers, in timber buildings, fuch pieces in the outward parts of a building, into which the girders are framed in all the floors but the ground-floor, then they call it a cell ; and garret floor, then it is called a beam. As to their fize and Iquare, it is the fame according to the a6l of parliament, with that of girders j it is here to be obferved, that it is not here meant, all the pieces which have girders in them, (and are not in the garret, or ground floor ;'^ but all fuch as are in the exterior part of the building ; whether in the front, flanks, or exterior part of the building ; for the pieces in the internal part of the building, into which girders are framed, are called Summers. Brew-House, a building adapted to the brewing, &cc. of malt liquors. In ereding a large and public Brew-houle to the befl advantage, fe- veral circumflances fliould be carefully obferved. i. That three fides in four of the upper part, or fecond floor, be built with wooden battons about three inches broad, and two thick, that a fufficient quantity of air may be admitted to the backs or coolers. 2. That the coppers be eredled of a proper height above the mafhing ftage, that the hot water may be conveyed by means of cocks into the maQi tuns, and the worts into the coolers. 3. That the fire-places of the coppers be very near each other, that one ftoker, or perfon who looks after the fire, may at- tend all. 4. That the yard for coals be as near as poffible to the fire- places of the copper. 5. That the malt be ground near the mafli tuns, and ti.e mill ereiied high enough that the malt may be conveyed from the mill immediately to the malh-tuns, by means of a fqiiare wooden fpout or gutter. 6. That the upper backs be not eredted above thirty- three feet above the refervoir of water, that being the greateft heigrit water can be raifed by means of a common fingle pump. 7. 1 hat the pumps which raife the water, or liquor, as the brewers call it, out of the refervoir into the water-backs, and alfo thofe which raife the wurts out of the jack- back into the coppers, be placed fo that they may be worked by the horfe-mill which grinds the malt. Bricks, 5'> B R I Bricks, as they fupply the place of ftone in our common buildings, and are compofetl of an earthy matter hardened by art, to the relem- blance of jl^at kini, may be very well coniidered as an artificial flone. Bricks are of a very ancient itanding, as appears from facred hiilory, the tower of Babel being built with them; and it 15 faid, the remains are flill vifible. In the times of the firrt: king's of Rome, they built with maflive fquare ftones, which they learned from the Tufcans. To- wards the latter end of the republic they began to ufe Brick, having bor- rowed the pradiice from the Greeks. And the greateft, as well as moft durable edifices, of the fucceeding emperors, as the pantheon, &c. were built with Brick. In ihe time of Gallienns, the buildings were compofed alternately, of an order cf Brick, and an order of toftu?, a kind of foft gritty ftone. After his time, they laid afide the ufe of Bricks and refumed flints. In the eaft they baked their Bricks in the fun. The Roman.- ufed them un- burnt, having firft left them to dry in the air, for three, four, or five years. Of the matter whereof Bricks are made. Pliny fiys, if you would have good Bricks, they muft not be made of any earth that is fall of fand or gravel, nor of fuch as is gritty or llony, but of a greyifli marl, or whitifti chalkey clay, or at leall of reddifli earth. But if there is a necefiity to ufe that which is fandy, choice (liould be made of that which is tough and ftrong. He aUb adds, that the beft feafon for making. Bricks is the fpring; becaufe they will be fubject to crack and be full of chinks, if made in the fummer. He direfts, that the loim of which Bricks are made, be well fteeped or foaked, and wrought with water. Bricks are made of a clayey or a loamy earth, pure, or with various mixtures J they are fhaped in a mould, and'after feme drying in the fun or air, are burnt to a hardn«fs. This is our manner of maknig Bricks ; the ufe of them was very anient, but whether they were alA'ays made in the fame manner admits a doubt ; we are not clear what was the ufe of flraw in the Bricks for building in Egypt, and there is room to quellion whether thofe of many later periods were ever expofed to the fire. There are remains of great Brick buildings of the Romans, in which the Bricks feem never to have been burnt, but to have been hardened by a very long expofure to the fun ; and this their own accounts confirm ; mention being made in fome of their writers of four or five years drying for this pur- pofe. The Greeks built with Bricks, and they ufed them of fix ditferent fliapef, or at leaft fo many different fizes j three being the principal, and there being as many exad: half fizes ; this gave a variety to their appear- ance. We are in general tied down by cuftom to one form and one Gze, which is truly ridiculous ; eight or nine inches in lengto, and four in breadth. B R I 57 breadth, is our general meafure; but beyond doubt there might be other forms and other fizes introduced very advantageouOy. Sir Henry Wot- ton mentions with commendation a particular form of Brick from Daniel Barbaro, which is in fiiape triangular, of equal fides, and each a foot long The thicknefs he mentions is an inch and half,, fo that his may be well enough eddied a kind ot thick tiles, but that may be altered at pleafure. There is no doubt but Bricks of this and other regularly an- gulr forms might be ufed with advantage in many parts of our common buildings. It has been propofed by feme to fteep Bricks in v/ater after the burn- ing, and then burn them over again, in order to give them greater ftrength; but this may be much better done by a proper choice of the materials, and a thorough fkiil and fufficient labour in tempering them. It is an obfervat'on of PallaJio, that the antients made their Bricks of a larger fize, which were intended for great buildings, and this was tertainlv right and reafonable; but he is aware of the difficu'ty there mull have been in thoroughly and equally baking of fuch ; we are alfured,. by the very names, that the Greeks had Bricks of five palms long, that being the fenfe of the name given to the largefl lort they ufed in com- mon buildings. The manner of burning is a thing very efTential in the flructure of Brick. It is commonly done in a clamp about LondoJi ; but in fome places in a kiln. Some of the finefl: Bricks are burnt in the kilns eredted for tiles. The degree of burning makes a coniiderable difference in the condi- tion of the Bricks ; but their principal diftindlit n is from the nature of the mate'-ials with which they are made; thefe being not only various ia themfelves,. but made different m a much greater degree by the mixtures given them in the working. A great variety of Bricks have been contrived by different perfons, and made at different times; and long perplexed defcripiions have been given of the way of fabricating them ; but at prefent they are in a manner reduced to four forts, our builders finding thefe fufhcient to anfwer every purpofe. Thefe are place Bricks, grey Stocks, red Stocks, and the finell- red or cutting Bricks. Adding to thele two or three foreign kii.ds im- ported for paiticu ar purpofes, we have before us all that is uled in this way, anu it would be ricedlels for us to meddle with any other ; our pur- pole being to' write not for the fatisfacftion of an idle and uleleis curio- fity, but f)r the fervice of the pradical builder, and of the gentleman- who employs hirn. As to the materials of Bricks* wc have already faid they are all made of- earth of a clayey or loamy nature ; the more pure the earth ufed is, the hardei: and firmer the brick will be; but then the lefs mixture there is Q with 5$ B R I with it, the more labour it will require in working. The Brick-makers regulate themfelves according to this rule, and finifh their work accord- in p- to the fervice for which it is intended. Grey Stocks are made of a good earth well wrought, and with little inlxture. Place Bricks are made of the fame earth, or worfe ; with a mixture of dirt from the flreets ; and thefe are often fo very bad they will hardly hold together. This is the principal difference between the two kinds of common Bricks, as to their fubllancej the grey Stocks being found and firm, becaufe the earih of which they are made is purer, aiid the Place Bricks being poor and brittle, becaufe of the mixture of other matter with that earth and Isfs working. Red Stocks and the Red Bricks, called alfo from their ufc, cutting Bricks, owe their colour to the nature of the clay of which they are made ; this is always ufed tolerably pure, and the Bricks of the better kind are called by fome clay Bricks, becaufe they are fuppofed to be maae of nothing elfe. We do not pretend here to enter into the niceties of the Brick- maker's bufinefs, every profeflion has its lecrets, which are kept among thofe who follow it ; neither is it our bufinels to inftruft the reader in making of Bricks, but in ufingthem in building. Thus much it was neceflary to fay, that he might underftand the na- ture of thefe as well as that of the other materials wherewith he is to work; and this is the general account of them. The grey Stock, he fees, are made of a purer earth, and better wrought, and they are ufed in front in building, being the ftrongefl and handfomeft of this kind ; the place Bricks are made of the clay, with a mixture of dirt and other coarfe materials, and are more carelcfsly put out of hand ; they are there- fore weaker and more brittle, and are ufed out of fight, and where lit- tle flrefs is laid upon them ; the red Bricks of both kinds are made of a particular earth well wrought, and little injured by mixtures, and they are ufed in fine work, in ornaments over windows, and in paving. Thefe are frequently cut or ground down to a perfedl evennefs, and fet in putty inllead of mortar; and on many occafions they make a very beautiful appearance m this manner. Thefe are the three kinds of bricks commonly ufed by us in building, and their difference is owing to this variety in the materials. The place Bricks and grey Stocks are made in the neighbourhood of London, wherever there is a Brick work ; the two kinds of red Bricks, depend- ing upon a particular kind of earth, can only be made where that is to be had ; they arc furnifhtd from feveral places within fifteen or twenty iniles of London, We B R I 59 We have already obferved, that there were two or three other kinds of Bricks to be named which are imported from other countries ; and there is alio one of the red or cutting Brick fort that is of our own manufac- ture, and for it^ excellence deJerves to be particularly mentioned; this is the Hedgerly Brick; it is made at a village of that name of tiie famous earth called Hedgerly loam, well known to the glafs-makers and che- mifts. The loam is of a yellowish colour, and very harfli to the touch, containing a great quantity of fand ; its particular ex'cellence is, that it will bear the greateft violence of fire without hurt ; the chemifts coat and lute their furnaces with this, and the ovens at glals-houfes are alfo re- paired or lined with it, where it ftands all the fury of their heat without damage. It is brought into London for this purpofe, under the name of W'indfor loam, the village being near Windfor, and is fold at a large price ; the Bricks made of this are of the finefl: red that can be imagined, they alfo call them fire Bricks, becaufe of their enduring the fire ; and they are ufed about furnaces and ovens in the fame way as the earth. The foreign Bricks that are to be named are the Dutch and Flemiili Bricks and clinkers ; thefe are all nearly of a kind, and are often con- founded together ; they are very hard, and of a dirty brimftone colour ; fome of them not much unlike our grey Stocks, others yellower. The Dutch are generally the befl baked, and the Flemifh the yelloweft. As to the clinkers, they are the moft baked of all, and are generally warped by the heat. They are ufed on particular occafions, the Dutch and Flemifh for paving yards, and {tables, and the like ; and the clinkers, which come alfo from the fame places, in ovens. The reader, who has thus far acquainted himfelf with the nature and qualities of the feveral kinds of Bricks, their different flrength, colours and beauty, will eafily enter into the diftinftions that are made in theufe of them. As to their nature it is proportioned to their feveral degrees of goodnefs. The fine red-cutting Bricks are twice, or more than twice, the price of the beft grey Stocks j the red rtocks half as dear again as the grey ; and the place Bricks, as they are a great deal worfe, fo they are much cheaper than any of the others. The grey Stocks, and place Bricks^ are employed in the belter and worfe kinds of plain work ; the red Stocks, as well as the grey, are ufed fometimes in this bufinefs, and fometimes for arches, and other more ornamental pieces : the fine red cutting bricks are ufed for ruled and gaged work, and fometimes for paving ; but the red flones are more fre- quently employed when a red kind is required for this purpofe. The red cutting brick, or fine red, is the fineft of all bricks. In fome places they are not at all acquainted with this; in others they confound it with red Stock, and ufe that for it, though, where the fine red Brick 6o B R I is to be had pure and perfectly made, the difFerence is five to three in the fale price between that and the red Stock. The red and grey Stock are frequently put in arches gauged, and one as well as the other Cet in puttey inftead of mortar ; this is an expenfive work, but it anlwers in beauty for the regularity of the difpofition and fineness of the joints, and has a very pleafing effedl:. The fine red Brick is ufed in arches ruled and fet in puttey in the fame manner j and, as it is much more beautiful, is fomewhat more coftly. This kind is alio the moft beautiful of all in cornices, ruled in the fame manner and fet in puttey. The grey Stocks ot an'inferlor kind are ufed in bricking walls. The place Bricks are ufed in paving dry, or laid in mortar, and they are put down fiat or edgewife. If they are laid flat, thirty-two of them pave a fquare yard ; but if they are placed edgewile, it takes twice that number: in the front work of walls the place Bricks fliould never be admitted, even in the meaneft building. Thgt confideration therefore only takes place in the other kinds j and the fine cutting Bricks come fo very dear this way, that few people will be brought to think of them; fo that it lies in a great meafure between the grey Stocks and red Stocks. Of thefe the grey are mofl ufed ; and this not only bf.caufe they are cheaper; but in mofi: cafes where judgment is preferred to fancy they will have the preference. We fee many very beautiful pieces of workmanship in red Brick ; and to name one, the front of the green-houfe in Xenfington -gardens will be fure to attradl every eye that has the lead: ciVriofity ; hut this fhould not tempt the judicious architeft to admit them in the front walls of the buildings. Jn the firft place, the colour itfelf is fiery and difagrecable to the eye; it is troublefoine to look upon it; and, in lummer, it has an appearance of heat that is very difagrceable ; for this reafon it is mofl improper in the country, though the ofteneft ufed there from the difficul- ty of getting grey. But a farther confideration is, that in the fronts of mofi; buildings of any expence, there is more or lefs fi:one-work ; now it were to be wifi::ed, that there fhould be as much conformity as could be bad between the general nakednefs of the wall and thefe feveral orna- ments which projedl from it ; the nearer they are of a colour the better they always range together; and if wecafi: our eyes upon two houfe;-, the one red, and the other grey Brick, where there is a little ftone work, we fhall not be a moment in doubt which to prefer. There it fouiething h?.rfli in the tranfition from the red Brick to Hone, and it ieems altoge- ther unnatural; in the other, the grey fi:ocks come fo near the colour of flune thu the change is Icfs violent, and they fort better togethe;. For this reafon alio the grey Stocks are to be judged befi: coloured - 'hfn they hiive leafi: of the yellow call ; for the nearer they come to the colour of ilone. B R I 6i flone, when they are to be ufed together with it, it Is certainly the bet- ter. Where there is no flone woric there generally is wood, and this being painted white, as is commonly the pradtice, has yet a greater efFevfl with red brick than the ftone workj the tranlition is more luddcn in this than the other;, but, on the other hand, in the mixture of grey Bricks and white paint, the colour of the Brick being foft, there is no violent change. The grey Stocks are made at this time to a great excellence about Lon- don, as many new pieces of Brick work fhew to the credit of the under- takers. The duke of Norfolk was fo nice in this refpedl, that he had the Bricks brought from his eftate in that county for the building the front of his houfc in St. James's Square ; but the event ftievvs, that his Grace might have been better fupplied near at hand, as to colour, with equal hardnefs. The greatefl advantage that a grey Stock, wliich is the llandard Brick, can have, is in its found body and pale colour j the nearer it comes to flone the better ; fo that the principal thing the Brick-maker ought to have in view, for the improvement of his profeflion, is the feeking for earth that will burn pale^ and that will have a good body, and to fee it has fufficient woiking. The judicious architect will always examine his Bricks in this light, and will be ready to pay a price where it is merited by the goodnefs of the commodity. The utility and common pradlice of building all our edifices of Brick, both in London and the country, arifes from motives too obvious to need a definition, fince it is generally confidered to be much the cheapell, a^ well as the moft eligible fubftance that can be invented for the purpofc, both in point of beauty and duration, and inferior to nothing but wrought fione. The great principle in the pradice of Brick- work lays in the procli- vity, or certain motion of abfolute gravity, caufed by a quantity or muU tiplicity of fubftance being added or fixed in refiilable matter j there- fore naturally tends downwards, according to the weight and power im- prclTed. From which obfervations the requifite inferences may be drawn, and fuch remarks made, as may enable the journeyman to eredthls works with fuch accuracy, that no bad confequences may attend, and, more- over, avoid unnatural fettlements. And firft it may not be amifs to confider the motive of this above- mentioned proclivity, which is chiefly caufed through the yielding mix- ture of the matter of which mortar is compofed, and cannot well be re- duced to any fyftem of certainty ; becaufe the abfolute weight of a Brick, or any other fubftance laid in mortar, will naturally decline according to the fubft'.nce or quality of it j in which cafe particular care fhould be taken,, that it is of a regular quality all the way through the building j R and 62 B R I and likewlfe that the fame force fliould be uTed to one Briclc as another ; I mean the flroke cf the trowel; a thing, or point in pradtice, of much more confequence than is generally imagined ; for if a Brick be aftuated upon by a blow, it will be a much greater preflure upon it than the ab- folute weight of twenty Bricks: before which cari be properly laid, in form and arrangement, with the advantage of the weather in a favourable fealon, may be fo dried or confolidated, that no fettlement can enfue from other defeds than that of an overfight in the foundation. The many bad effedls that arife from mcrtar not being of a proper quality, fliould make mafters very cautious in the preparation of it, as well as the certain quantity of materials of which it is compofed, that the whole llrudlure may be of one fubftance. There is one thing which often caufes a bulging in large flank-walls, efpecially when they are not properly fet off on both fides ; that is, the irregular method of laying Bricks too high on the front edge j that, and building the walls too high on one fide, without continuing the other, often caufes the above defetfls. Notwithftanding, of the two evils, this is the kafl ; and Bricks fliouid incline rather to the middle of the wall, that one halfof the wall may be a fliore to the other. But th-s method, too much followed, will be more hurtful than beneficial, becaufe the full width of the wall doth not take its ablblute weight, and entire y remove? the fpecific gravity from its firft line of direflion, which in all walls fliould be perpendicular and united ; whereas, if the above method is ilretched to excefs, and the walls have a fuper-incumbent weight to bear adequate to their full flrength, a disjundfive digreffion is made from the right line of direftionj the conjunctive flrength becomes divided ; and inffead of a whole or united fupport from the wall, its ftrength is fepa- ratcd in the middle, and takes two lateral bearings of gravity j each in- lufficient for the purpofe; therefore like a man overloaded either upon his head or fhouldcrs, naturally bends and ftoops to the force imprelled ; in which mutable flate the above grievances ufually happen. Another great defedt we frequently fee in thefronts of houfes ; in fome of the principal ornaments of Brick-work, viz. arches over windows, &c. and vvhitli is too often caufed by a want of experience in the rubbing of them; which is the mofl: difficult part of the branch, and ought to be very well confidered. The faults I mean, are the bulging or convex fi- tuation vvc often fee arches in, after the houfes are finifhed, and Ibme- times loofe in the key or center bond. The firff of thefe defedls, which appears to be taufed by too much weight, is in reality no more than a fault in the praftice of rubbing the Bricks too much off on the infides^ for it fliould be a ftanding maxim (if you expedl them to appear ftreight under thdr proper weightj to make them the exad: gauge on the infide, that B R I 63 that they bear upon the front edges ; by which means their geometrical bearings are united, and all tend to one center of gravity. The latter obfervation, of camber arches not being fkewed enough, is an egregious fault ; becaufe it takes greatly from the beauty of the arch, as well as its fignificancy. The proper method of fkewing all camber arches (hould be one-third of their height. For inftanccj if an arch is nine inches high, it fhould Ikew three inches j one of twelve inches, four; one of fifteen inches, five; and fo of all the numbers between thofe. Obferve, in dividing the arch, that the quantity confifts of an odd number; by fo doing, you, will have proper bond ; and the key- bond in the middle of the arches j in which ftate it muft always be, both for ftrength and beauty. Likewife obferve, that arches are all drawn from one center; the real point of camber arches is got from the above proportion. Firft, divide the height of the arch in three parts ; one is the dimenfions for the fkewing ; a line drawn from that through the point at the bottom to the perpendicular of the middle arch, gives the center; to which all the reft muft be drawn. There are many other difficult jobbs in Brick-work -, as groins, niches, 5cc. all which fliall be treated of in their proper order. Of Brick Groins. A Groin is the interfering or meeting of two circles, Sec. upon their diagonal elevations drawn upon the different fides of a fquare, or any other figure, and whofe principle of flrength lies in the united force of eleva- tion, divided by geometrical proportions to one certain gravity, which is the center to which all the bearings tend. The di.^culty that attends the execution of a Brick Groin lies in the peculiar mode of appropriating proper bond at the interfering of the two circles, as they gradually rife to the crown to an exadt point; in the meeting or interfedtinty of thofe angles will be formed a kind of rib in the infide, which fhould be parti- cularly ftreight and perpendicular to a diagonal line drawn upon the plan. There is no definition of a thing of this fort, either by lines or defcrip-- tion, equ'al to what will occur to the learner in the pradice of them. After the centers are fet, let the bricklayer apply two or three Bricks to an angle j by which means he will effedlually fee how to cut them as well as the requifiles of bond. There is nothing fo certain as praftice for the folving any difficulty ; it is by this axiom that every proof is founded, and without it the moft flagrant idea of lines, and theoretical fpeculation, would be in many cafes detedive; becaufe a falfe notion, or a wrong conception, nii^'ht lead the wifeft man into an error. It is upon this principle of pradice I propofe to render my inftrudions familiar. But 64 B R I But to return to the Groins. The workman muft obferve, that the manner of turning Groins with refped: to the fides, is the fame as other, arches and centers, except in the angles, which muft be traced for its properties, as 1 obfei ved by applying the Bricks ; and if the arch is to be rubbed and gauged, you muft divide each arch into an exaft number of parts, and extend the lines till they meet in the Groin; by whiclv means you will eafily find the curve for the angle, from which you muft make your tfmplets; obferve, in fixing the centers, that the carpenters raife them fomething higher at the crown, to allow for fettling, which fre-t quently happens, fometimes by the prefTure upon the butments, other-,- wife from the length of the crown. Obferve in building of vaults, that the piers or hutments are of fuf- ficient ftrength ; all hutments to vaults, whether groined, or only arched, fhould be one-fixth part of the width of the fpan ; and, moreover, if there is any great weight to be fuftained, bridgings of timber Ihould be framed, to difcharge the weight from the crown of the arch ; after a vault or Groin is finiflied, it is highly neceflary to pour on a mixture of tefras, or lime and water, on the crown ; and give it ibme little time to dry, before you ftrike the centers, in order to cement the whole together. Rough Groins have no more value put upon them than common vaults,, which are included at per rod with common Brick- work, except the an- gles of Groins, which are meafured after run lineal, and fometimes vil- owed by furveyors is. per foot j many mafters charge is. 2d. per foot. Of a NicH in Brick-work. A Nich is the inner or concave quarter of a globe, and ufually made in walls on the exterior parts of a building, to place figures or ftatues in. The practice of this in Brick-work is the moft difficult part of the pro- feflion, on account of the very thin fize the Bricks are obliged to be re- duced down at the inner circle, as they cannot extend beyond the thick- nefs of one Brick at the crown or top ; it being ufual, as well as much the neateft method, to make all the courfesftanding. The moft familiar way to reduce this point to practice, is to draw the front, back, &cc. and make a templet of pafteboard, after you have di- vided the arch for the number of Bricks. My reader muft obferve, that one templet for the flanding courfes will anfwer for the front, and one lor the fide of the Brick ; and at the top of the ftreight pa. t, from whence the Nich takes its fpring, you. muft remember to make a circle of the diameter of eight or nine inches, and cut this out of pafteboard alfo, and divide it into the fame number of parts as the outward circle; trom which you will get the width of your front-templet at the bottom. The reafon of this inner circle is to cut off the thin conjundion of points that muft all finifti in the center, and which in Bricks could never be worked B R I 6$ worked to that nicety; it being impoflible to cut Bricks with any accu- racy nearer than halt" an inch thick; within the inner circle the Bricks muft be lying. It will be neceffary to have one templet made convex, to try the faces of Bricks to, as well as fetting of them, when they are gauged. The ftone you rub the faces of the Bricks upon, muft be cut at one end in the exad: form of the Nich, or it will be impoflible to face them proper. The level of the flat fides of the.Bricks is got by dividing the back into the number of parts with the front, and all ftruck to the center ; from the circle of the front of one Brick fet yc ur level, which will anfwer for the fides of the whole : obferve, that the Bricks hold their full gauge at the back, or when you come to fet them you will have much trouble. Jobbs of this kind are ; and when they happen, fl:iould bear a price equal to their value. The tollowing is what materially concerns the bricklayer, in an act of the 14th of Geo. 3. for the regulation of Brick buildings and party walls, in London, Weftminfter, St. Mary le Bone, Paddington, Pancras, and St. Luke, at Chelfea. It will be neceflary to obferve a few things which refpedl the Brick- layer, before we immediately enter into the defcription of the manner he is to execute his work; I ft, That there are only the firft, fecond, third and fourth rates of building, whofe thicknefs of external and party-walls are defcribed in the a<5t. The First Rate. Every church, chapel, meeting-houfe, and other place of public wor(hip. Every houfe or building, fordiftilling or brewing liquors for fale, for making cf foap, for melting of tallow, for dying, for boiling or diftil- ling turpentine, for cafting brafs or iron, for refining of fugar, for mak- ing of glafs for chemical works for lale, of what dimenfion foever the fame refpetlively are built. And every warehoufe and other building (except fuch buildings as arc defcribed to beef the fifth, fixth or feventh rate) not being a dwelling^, houfe, which exceeds three clear ftories above ground, exclufive of rooms in the roof, or meafures in height 31 feet frcm the foot- way of either of the fronts, to the top of the blocking coiirfe or parapet. And every dwelling-houle with offices belonging and adjoining, or con- nected othei wife than by a fence or fence-walJ, or covered pallage open on one or both fides ; when finilhed exceeds the value of S50 1. And alfo every dwelling-houfe which exceeds nine fquares ef building on the ground plan. Are all and each of them of the firft rate. S Ths he B R I The. Second Rate. Every warehoufe, ftable and other building, ^except fuch buildings aa are di.icribcd to be of the lirft, fifth, lixth or feventh rate) pot bring a dwcliine houle which exceeds two c'ear ftories, and d'jes not contain- more than three clear ftories above ground, exciuuve or rooms in tiie ro^f, or mealures in height 22 feet, and not amounting to 31 feet frortv the foot way of either of the fronts, to the top of the blccking-courfe, or para|.et. And every dwelling-houfe with offices belonging and adjoining, or conneded otherwife than by a fence or fence-wall, or covered paffage open upon cne or both fides, when finiilicd exceeds the value ot 300 1. and does not amount to more than 850 1. And alfo every dwelling-houle, which exceeds five ftj^^uareSi. of building on the ground plan, and does not amounit to more than ninfefquares, aris all and each of them of the fecond rate. The Third Rate. Every warehoufe, ftable, arid other building, (except fuch buildings as are defcribed to be cf the firft, fifth, fixth, or feventh rate) not being a dwelling-houfe, which exceeds one clear flory, and does not contain more than two clear ftories above ground, exclufive of the rooms in the roof, or meafures in height more than thirteen feet, and does not amount to twenty-two feet, from the foot-way of either of the fronts, to the top of the blocking-courfe, or parapet. And every dwelling-houfe with ofiices belonging and adjoining, or connecled otherwife than by a fence, or fence-wall', or eover-ed paffage open on one or both fide?, when finiihed, exceeds the value of 150 1. and. does not amount to more than 300 1. And alfo every dwelling-houfe, which exceeds three and an half fquares of building on the ground plan, and does not anoount to more than five fquares, are all, and each of them, of the third rate. The Fourth Rate. ' Every warehoufe, ftable, and other building (except fuch buildings as are defcribed to be of the firft, fifth, fixth, or feventh rate; not being a dwelling-houfe, which does not exceed one clear flory above ground,, exclufive of rooms in the roof, and meafures in height not more thaa thirteen feet from the foot-way of either of the fronts to the top of the blocking courfe, or parapet. And every dwelling-houfe, with offices belonging and adjoining, or connedled otherwife thaa by a fence, or fence-wall, or covered paffage open on one or both fides, when firnillied, does not exceed the value of 1 50 L And B R I 67 And alfo every dwel'ing-houfe, which does not exceed three and an half (quarcs of building on the ground plan, are all, and each of ihrin of the fourth rate. The 2ft diitfts, that every mafi. r- vvoikaian, or owner, (hall give 24 hours not ce to the furvjyor, in whole difi: ift any building whatever, from the fi:ft to the Icvcnth rate, is to be altered or erefted. That as it is fobnd by experience, that moft buildings, in general, are more often begv, by the bricklayer than by the carpent'T, there will be no kind of impropriety in faying, it will be the bricklayer's bunnefs to give fuch n tice, except where a foundaUon is to be piled or planked; and tlitn it becomes the bufinefs of the carpenter. But be this as it may, the obfervation is only made from fuppofing, that the workman who lays the firfl: ftone would wifli to lay it right, and therefore if the furveyor cannot attend within the 24 hours, he muft himleif obferve the direftions of the aft, which will be hereafter feve- rally explained. And firft of external walls. The aft calls every front, fide, or end wall, &c. (not being a party wall) an external wall : a<"d as it has before been faid, that there are hut four rates of building, whofe thicknefs of walls is defcribed by the ait. The wails to each rate bath in fublfance and form, according to the ex- prefs declaration of the aft, are not to be lefs in thicknefs than as they are defcribed, yet it muft in courfe be prefumed, that they be made as much thicker as the nature of the l)uilding, or the owner of it may require. The footings to the walls are to be with equal projeftion on each fide, but where any adjoining building will not admit of fuch projeftion to be made on the fide next adjoining to fuch building, the aft allows it to be done as near as the cafe will admit, and this to each of the four rates. The bearing of the timbers in each rate, as girders, beams, or trim- ming joifts, Sec. which in all cafes, and in all the above four rates, may be as much as the nature of the wall will admit, provided there is left four inches between the ends of fuch timbers and the external furface of the wall. ■ The flories are to be made in number agreeable to the rate to which they belong; but their height may be made difcreti( nally. The aft exprcfles the thicknefs of the walls in feet and inches, as well as the number of Bricks of which fuch thicknefs is to be compofed; this lafl: methcd being thought moft familiar to workmen in general. The joints of the Brick-work mufl anfwer to the exprels number of Bricks of which luch wall is to be compofed. External walls, and other external inclofures to the firfl:, fecond,. third, fourth, and alio the ui'ih rate of building, when built hereafter, mull be of Brick, llone, artificial ifone, lead, copper, tin, flate, tile or iron ; or of Brick ftone, and fuch artificial flone, lead, copper, tin,, flate, tile,, and: 63 B R I 2nd iron together, except the planking, piling, 5cc. for the foundation, which may be of wood of any fort. If any part to an external wall of the firft and fecond rate is built whol- ly of flone, it is not to be lefs in thicknefs than as follows. Fiift rate, 14 inches below the ground-floor; 9 inches above the ground- floor. Second rate, 9 inches above the ground floor. W here a recels is intended to be made in any external wall hereafter to be built, it mufl be arched over, and in fuch manner, as that the archj and the back of fuch recefs, Ihall refpcftively be of the thicknefs of one Brick in length; therefore it follows, that where a wall is not mors than one Brick thick, it cannot have any recefs. No external wall to the firft, fecond, third, and fourth rate, is ever to become a party-wall, unlefs the fame fliall be of the height and thick- nefs above the footing, as is required for each party-wall to its refpec- tive rate. Party-walls. Every building of the firft, fecond, third, and fourth rate, hereafter to be built, which is not defigned by the owner thereof to have feparate and diftinft fide-walls, on fuch parts as may be contiguous to other buildings, muft have party- walls; and they are to be placed half and half, on the ground of each owner, or ot each building refpedtively, and may be built thereon, without any notice being given to the owner of the other part, that is to fay, the firft builder has a right fo. to do, where he is building againft vacant ground. All party-walls, and all chimneys, and chimney-fliafts hereafter to be built, muft be of good found Bricks, or ftone, or of found Bricks a/id ftone tegether, and muft be coped with ftone, tile or Brick. When the fituation of the floors are difltirent levels, it may not be im- proper to ftiew in what manner the walls muft be built, where fuch differ- ence ot level may happen ; as for example, fuppofe a party-wall is to be built between two eld houfes, and there is occafion to fink the cellar ftory of one of the houfes below the level of the floor of the other; in that cafe the wall muft have its declared depth, below the floor of the loweft building, and fo under the ground- floor; and alio above the garret- floor, which is to be carried up to its proper thicknefs, as high as the underfide of the floor of the higheft building. Stone corbets muft be inferte.j where the wall will not allow of a fuffi- cient bearing; becaufe the ad expreftly fays, there ftiall be 8 inches i of folid BiicK- work, between the ends and fides of all timbers which lay op- pofite t'.^, or on a level with other timbers of the adjoining building. Party-v/,.lls, or additions thereto, muft be carried up eighteen inches above tne roof, mesfuring at right angles with the back of the lafter, and twelve inches above the gutter of the higheft building, which gables againft B R I 69 againfl: it ; but where, the height of a party-wall fo carried up, exceeds the height of the blocking courfe or parapet, it may be made lefs thaa one foot above the gutter, for the diilance of two feet fix inches from the front of the blocking courfe or parapet. And where dormers or other eredlions are fixed in any flat or roof, within four feet of any party-wall, fuch party-wall is to be carried up againrt fach dormer, and mult extend at leall two feet wider, and to the full height of every fuch dormer or ere none are ftronger ; for thefe, when well framed, compofe a body more firm, than if cut in a vaft thicknefs from a fingle piece, the parts here iVengthen- ing and fupporting one another, Palladio has given a figure of one which he laid acrofs Cifmone, where the breadth of the river was a hun- dred feet ; its ftrength appears inconteflible from the ftrucfture, and experi- ence iTiewed it to be what it feemed ; but there is yet another great ad- vantage in this Bridge, which is, that it lies level with the reft of the road, and does not tire the traveller with an afcent and defcent. A per- fon unacquainted with mechanics fliudders to look upon it but in the re- prefentation ; but to thofe who know the fubjed: there appears no dan- ger. This advantage of building a Bridge without rife we very much re- commend to the architedt. Of the Conftrudlion of fuch a Bridge. The great fupport of a Bridge that has no intermediate piers mud: be at the banks, and in this cafe the natural ground is never to be trufled: therefore let the architedt begin by eredting on the fhore two mafly bu'tt- ments of flone capable to bear any prefiure, and refill any force. Thefe railed to the level of the ground, let him take the meafure of their dif- tance, and divide this into quantities of about fixteen feet. The fpacc thus reduced to a number of complete meafures, the fabric of the Biidge may be begun. Its breadth cannot be determined to feet or inches, nor needs there any fuch account : that is an article to be fuited to the immediate purpofe of each occafion. Let as many beams be cut as there aredivifions of this meafure, luppofe five ; and let their length be that of the breadth of the intended Bridge. Thefe make the beds of the fabric. Thefe laid, there are to be placed lengthwife on them other beams which make the fides of the Bridge : but there muft be a fmall fpace of the end of each of the firft beams free. The next part are the uprights, which fupport the railing. Thefe. muft be fixed on each fide directly on the firft laid beams; they muft be faftened ftrongly with cramps of iron, let through the hy^les^ made for that X purpole. 78 B R I purpofe, in ihofc ends of the beams which run out free beyond the Gde- pieces. This is the regular manner of working, and thus will be feen in a few pieces the extent and form of the intended Bridge. The uprights are not to be all of a length ; for the railing mull be highefl in the middle of tile Bridge-, and flant to nothing at the two ends. The pofts, or up- rights, muif therefore be ot the form proper to i'uppyrt fuch a figure, and gradually fliorter: thefe, according to the pleafure of the architedl, or intention of the bridge, in regard to plainnefs or ornament, may be either left naked or plain as they are cut. or crowned with balls. In the fim- plcft dcfigns they may be left fquare as they are cut off; in thofe, a little more ornamented, the tops may be cut into a number of angles, and capped, if needful, with iron ; and in thofe moft intended for lliew, tho' nothing in this kind (liould aim at much, they may be cut off level at the top, and a ball with a proper bafe and neck may be fixed upon them. The iron cramps which fix thefe uprights to the crofs beams are to run up a great part of their height, and there mull be holes through them for faifening them by (Irong iron pins. They muft be faflened again be- low with pins or fmall bars of iron. By this means every part of the Bridge will be firmly united, and the feveral members will fupport one another-, the crofs-beams, the fide-beams, and the uprights are by thefe cramps faftened into one folid mafs. This conftrudlion is not only firm in itfelf, but it has that happy flrength we named in Csfar's Bridge, the parts fupporting one another, and joined in this manner, are made more firm, the great weight prelTes them. This is at leaft true of all weights which can ever come upon a Bridge; and that is enough for pradlice. The more they are prefled the falter they clofe, and the ftronger is the work. The beft way of working is to begin from the buttment on each fliore, and the parts may be thus brought forward each way to meet one another. Of wooden Bridges over larger Rivers. The conftrudion of a Bridge of one arch is not limited to any parti- cular meafure in the breadth of the water; but the eye of realon will diftinguilh without being told, that thefe kinds are fuited to fmaller rather than larger rivers. We will fuppofe the architedl employed to build a Bridge of timber over a river, of twice the breadth of fuch as we have named; in this cafe it will be proper to fupport the work with lolid buttments on each (hore, and to allow it at certain dillances piers, or fupports of firm upright timber, from the river's bed. The imaller the number of thele the better, provided the Bridge have due ftrength, be- caule the fabric will in proportion be lels liab.e to accidents. We have ©bferved, that the motl frequent dcftrudion of thefe Bridges is from ice, timber. B R i 79 timber, or other heavy matter thrown againft them by floods. The fewer the lupports in' a river of given breadth, the more chance thefe folid bodies will have of going free, or of being waflied through them^ inltead of remaining to bear with the full force of the water agamll them. The number is to be fo propcnioned, that one may rtand at about five and thirty feet diOance from another; this will leave wide arches, and there- will eafily be llrength enough given in the conllruftion ot the work with thefe diftances. We have not only the authority of geometrical computation in this cafe for the fupporting us, but the pradice of Pal- ladio ; he threw over the Brent near Ralfano. The river is a very rapid one, and its brendth in that place a hundred and eighty feet. The mea- fure he allowed between pier and pier was thirty-four feet fix inches, and the Bridge ftood all the fury of the torrent ; very elegant in its con- ftrudlion, and a iafting monu^nent of his fkill. The rows of piles in this cafe fhould be placed firmly, and they mufl: be in themfelves folid j a foot is the belt dillance for them one from^ another; their number fhould be eight in each row; and they fhould be a foot and a half in diameter ; thirty feet is a natural and ufual length ; and, according to this conllrudion, .the Bridge will have a breadth of fix and twenty feet. Over the rows of piles are to be placed crofs-pieces or joifls ; the length of thefe is to be determined by the extent of the others, and they mull be well faftened every where. Thefe keep all to- gether. Over ihefe crofs-pieces, plumb with the fupports, are to ba placed eight other pieces lengthways. Thefe would be in danger of fwagging from their great length, if no farther care were taken ; but they will be very well fup^jorted by carrying itrong fhouldcr-pieces each way from them ; and otl.er beams mufl be railed flanting under them from the piles, and join a middle-piece. There Is here a form refembling a quadrant of a circle ; and it is not only a foorcc of flrength l:at beauty. The llrength refults from a very- plain pfinciple; that the beams which make the length of the Bridge are double in the miudle, and ihey and their fupports mutually fix one another. The work being thus far advanced, the bed of the Bridges is to be laid on J this mufl coniiH: of pieces kid acrofs the beam's we have juffc named. The length of thefe mull fe a little more than twe breadth we h.we al- lowed for the Bf.dge; for it will be proper to let their ends projedl a lit- tle. Ihcre is always an additional llrengih in this; and the ends thu& projedling refemble the modillions of a cornice, and are an ornaments A D'-idge of this kind will be flrong, beautiful, and of little expcnce;, it Will ber.r a fuperftructur. it the architedl pleafe. Palladio covcre.l luch. a cue with a roof fupportcd by column's ; but for common occafions a. railing of fufficient llrength, bieail high,, fupported by uprights,, and decorated. 8o B R I decorated with balls, as we mentioned on a former occafion, will per- fcdly well arifwer the purpofe. The banks muft be in thefe cafes fe- cured by a Hrong wood-work, or by buttments cf ftone ; and upon the fame principles may be built a variety of Bridges of this kind ; the tim- ber being fuited t :> the depth of the water, and to the length of the Bridge. The lighter the lefs experience ; but where there is great breadth, the ftrength ought to be more confulted than the charge ; for the danger is great in flight Bridges, and repairs are difficult. Of Stone Bridges. The wooden Bridges whereof we have hitherto treated are cheap in proportion to thofe of flone ; and they will ftand a long time, but the folidity, dignity, and fupcrior elegance of the others, when well wrought, leave no room for comparifon in point of real excel- lence. Thefe therefore are the kind the architedt fliould propofe where the proprietor does not limit the expence, and where he hopes to do him- felf the moft lafting honour. The principles on which the flone Bridge is to be conftruded, differ in nothing from thofe of timbtr ones with re- fpe(fl to choice of place and fituation. The bottom muft be founder for thefe than for the others, becaufe mere ftrefs is laid upon it; and the banks muft be defended by buttments of ftone, which make a natural part of the work. Thefe heads or buttments at the banks cannot be too ftrong : they will be expofed to a great weight; and upon their firmnefs will in a great meafure depend that of the whole Bridge : for this is to be confidered as one great arch, and it muft have its latural preflure. If thefe buttments, which are its fupport give way, all will be in dan- ger of cracking; but while thej are firm, the more the weight, the more compadl the whole becomes. The buttments, or head-works, muft be carried a confiderable length upon the ftiore, that they may have the more fecurity and force; and the way being carried over there to the Bridge, not only the ftrength will be more, but the paflage will be continued, though waves and floods fhould eat away the banks. The buttments being made, the next confideration regards the piers. Thefe muft be proportioned in number to the extent of the river and intended form of the Bridge, but it is an univerfal rule, that they fhould make an even number. This is a dodrine delivered from father to fon among the architeds, though many receive it without examination j and thol€ who call- them- felves a little wifer, have rallied it as a piece of fuperftition. The judi- cious archited: will return the raillery upon themfclves : he will fhew them by various dcfigns, that an even number of piers make a more agreeable appearance than an odd; and he will add, that fuch a number leaves an arch in the middle, where the odd number would place a pier. The courfe of the river is naturally ftrongeft in the middle ; and would an archited place a pier to obftrud its courfe ? The giving a larger openmg thaa B R I 8t than for the reft in that place, allows paffag^e where It is moft wanted, and is every way moCl: rational and convenient. In many places the courfe of the river is lefs regular; but ftill it is eafy to find where it is ftrongeft. This will be feen by the clufters of floating refule matters that are carried upon it; and even this is to be confulted in a fecondary manner ; the architedt contriving openings, and not piers in thefe places. The places for Bridges we have confidered before; and this being chofen, lomething is to be added as to the time of beginning the work. Autumn is the feafon when rivers are lowed in water; this is therefore the moil eligible time i and in places where the tide has influence, all experiments mult be taken at low water.. In fome places the foundation is made by nature ; thefe are happy circumftances ; in others it muft be by digging. Gravel or rock are two fafe bottoms. On thefe any weight may reft ; and nothing is required but a level furface. We here fpeak of that hard, clean and folid gravel which lies in a mafs like rock, and is of a great depth. In fome rivers the bottom is a loofe gravel lying over mud; this is to be confidered in the fame light a& fand ; and both are to be dug through, if that can be done, til! the archited: comes to a found foundation ; for they are not of that nature ; and no dependence muil be placed upon them. In fome places there lies a found bottom at a I'mall depth beneath them ; and in fuch inftances the fand or loofe gravel muft be dug away a fufficient corn- pals for laying the foundation of the piers. In other places no found bottom is to be found under them within any moderate depth ; and in thefe cafes recourfe muft be had to piling. For this purpofe piles or long beams of oak fhod with iron muft be ufed; the fand or loofe gravel muft be dug away to fome depth, and they muft be driven in with engines till they come to the firm ground and get fome way within it. Their heads are then to be fawn off level, and the work carried on upon them. When the foundation of the pier is laid, one part of the bottom mufl be enclofed and kept dry, that the workmen may purfue their bufinefs unmolefted by the water; and thus they are to proceed with the whole. The thicknefs of the piers muft be proportioned to the wiuh of the arches. About a fifth pait of th- breadth or the arch is the prjper meafure, but this may be varied according to the circumftances ; they will very rarely be requireu flcnderer than one-fixth of the breadth, or more maffy than aiounh. Vv hen the piers are thick, let them be built with large Ifones. They are to bear a gre?c deal. And they Ihould be ib bau d and faftened together as to be like a rock; they fhuuld be helti together with cramps ot iron foldered in with lead ; and theie bearing joindy the weight or preffure, the whole mafs will be as one Irone. 1 he form of the piers is left in a great meature to the fancy of the archited, only that "he muft oblerve not to oppofe a flat face to the ftrea^n. y Some 82 B R I Somt prefer a" circular front in this place, others a right angle: there is no preference to be given iri abfolute terms to either, but the occaiion muli determine. If the great care be not to interrupt the flream, an angle is the heft'; if there be fear of heavy objefts rtriking againfl it, the belt is the circular form. ■ "In the ccndruiftion of arches the work mufl: be very carefully done, and large materials ufed. There is no making a large arch of fufficient ftrcngth with fmall ftones. The ftones fl"iOuld be examined in regard to their quality as well as bignefs ; they mull: be found and firm, and they fhould be cramped in with iron. The calculation of what they are to bear fliould be always made upon the extreme j not from the common courfe of things, or knov/n weight of carriages, but like a proof of can - non with a double charge. Accidents may occafionally bring upon it a much greater weight than is firft thought ; or its fabric may from fome unfeen caufes be lefs folid than imagined ; it is beft therefore to err ori the fide of too much flrength. Of the form and covering of Arches. By Arches the fludent fl:iould underftand fegrnents of a circle. The Gothic are difclaimed, and there is no form which is capable of fo much ftrength as the plain fweep of a true circle; the elliptic fliould never be admitted for Bridges. In the firft conftrudlion of buildings, the Gothic or fharp Arch was not unnatural, but they improved who took oiFthe point. The firfi: Arches probably were fuggefted to men by the vaulted walks formed with double rows of trees ; thefe are very pleafing, and they are of the fame kind. Nature fends up the branches of trees in an oblique diredion, therefore they meet, where oppofite rows ftand near, in this pointed vault, refembling the common roof of a b.Trn. Thele the firft builders copied, but the fweep of a circle was foon found a more eligible figure, more noble in itfelf, more ftrong and capable of more bearing ; they were therefore unpardonable, who, knowing this improvement, fell back into the paths of barbarifm. The Arches of a bridge are therefore determined, by all the laws of fcience, to be of the circular form; they are more ftrong, more elegant, and capable of more duration as well as bearing. There yet remains a queftion which architects have not enough efta- blifhcd in their pradtice, though nothing is more plain in theo:y. 7 he Arch of a Bridge we have determined is to be a part of a circle, but of what quantity ? Tviore than the half of a circle cannot be ufed ; but lefs may, in various degrees ; and the judgment /liould diredl where the fancy of the architect ufually does. Let B R I g3 Let all be taken Into confideration together. The femicircle is the ftrongeft and the moft elevated of all figures for an Archj and it has the vaft advantage of all the preiTure falling upon the piers ; but with thofe advantages there are inconveniences ; the principal is height. It is a great defecft in the conftrudiion, to let a bridge tire the palTengers with a fleep afcent ; yet this in many cafes will be the neceflary refult of the femicircular Arch We fhall diredt how it may be alleviattd, but the architedl mufl refolve, whether thefe helps will or will not obviate the objeftions. The;e are alfo inftances where the difpofitlon of the piers will not well admit of femicircular Arches ; we have named the accidents on which the rule of this difpofition depends, fome of which are uncon- querable, and, of an abfolute neceffity, muft be complied with ; and in thefe cafes the ftrength and beauty of an Arch, fuch as we recommend, are not enough to atone for variations in the effential parts. Therefore the quantity of the Arch muft be lelTened ; and architedls may be favcd a great deal of needlefs calculation, by being told the next proportion for thefe parts to the half of a circle is a third. This is his choice, but a great deal more is to be confidered ; for the nature and bearing of the work are altered by it. In a dcfign where the Arches are to be femicircular, the great atten- tion of the architect muft be to give ftrength to the piers, and a fecure foundation : for in thefe arches all the weight prefTes there ; in the lefler Arches the force will be very great upon the buttinents or heads built at the banks ; and thefe muft therefore be ftrengthened accordingly ; we have diredted, that in all bridges this be well fccured, but in thefe there muft be greater caution. Here the ftudcnt fees another inftance of that invariable rule we gave him of taking the whole of every thing into conhderation before any part is executed. The ftrengthening the banks is always proper and al- ways neceffary ; but we fee here that, befides the various accidents which may make it more needful in one place than another, the very con- ftrudtion cf the bridge itfelf may in a great degree influence in this matter. Of the duration of Stone Bridges. If the proprietor or the public, on lelTer or on greater occafions, ftiould bs induced by the cheapnefs to prefer a Bridge of woovJ, we fliall remind him of the vaft difference in duration of the two kinds, and may fupport what would alfo feem ex- travagant accounts, from the remains of Roman Bridges, fome almoft entire. The Elian Bridge, the work of old Romans, Itands to this day ; it is the Bridge of St. Angelo over the Tyber. The Quartro Capi Bridge, fo called from the four-faced ftatue we have mentioned treating of the Termini, is the Fabrician Bridge, named from Fabricius, iis great founder. 84 B R I founder. The Certian Bridge of Old Rome is St. Bartiiolomew's Bridge, of the modern denomination ; and the Ruftic Bridge, called at this time St. IVIary's, is the famed Senatorian Bridge of antique Rome. All thefe remain in a condition that does great honour to their build- ers, and will, in the eye of reafon, plead far beyond words in pre- ference of thofe of ftone. Thefe the judicious architedl fhvuld quote to thofe who think of nothing but the price of ftrudlures ; and we have told him alfo how to build for ages. Of the conftrudtion of Stone Bridges. The oinaments of which fione Bridges are capable are very great j but, to be properly employed, the archited: murt: take them into confideration in the very beginning, and form his whole defign accordingly. This may be varied in the num- ber and form of the arches ; and the fuperftrudlure may be carried to any degree of elegance. We have fliewn how a Bridge of timber may carry columns fupporcing a roof, even where the whole fabric is far from maffy. Jn more folid ftrudtures of that kind, and much more in thofe of ftone, the genius of the architecft is left unlimited ; and houfes and public places of refort may be contrived upon them. We fhall confider firft thofe of a fimpler Strudlure. The dimenfions of the river are the firfl: articles in the confulting fuch a defign; and, according to thefe the Bridge may be eredfed with dif- ferent numbers of arches. A hundred and eighty feet was a mealure we took before for a wooden Bridge, we will fuppofe a river of the fame extent to be the place of a ftone. The current, the ground, the banks, and every circumfl:ance confidered, we will fuppofe three arches allowed to the Bridge. The central arch muft be larger than the others, but the proportion of that excefs muft be confidered. If we allow fixty feet for the breadth of this, and forty-eight for that of the two others, there will be fufficient proportion ; and the piers needful tor fupportmg fuch a Bridge will leave free compafs enough for thecourfe of the river. Ihefe piers, if made of the folid and large materials we have direiSed for thefe purpofes, need only have a fifth of the meafure of the middle arch for their thicknefs, that is, twelve feet ; and this they mufl be allowed with the bcft workmanfhip. If the current be very fliarp, the piers muft projed: forward beyond the body of the Bridge, that they may ftand uninjured, not only the force of the flream, but the accidental blows they may receive from hard bodies brought down upon the water. There is no fecurity againfl thefe accidents equal to this of carrying on the pier beyond the meafure of the Bridge, except that of carrying on a lower building far beyond that. This is oftener done than needful. This kind oH bridge, under fuch dimenfions, of the length, number of the piers, and dilpoiition of the B R I 85 the arches, would have been too fteep of afcent with the femiclrcular form; therefore the fmaller rneafure is every way preferable, and under this dif- tribution of parts , it will be very elegant. No more is required for the conftrudlion of this Bridge, and the architedl is at liberty to adopt what degree of ornament he pleafes. There muft be a defence breaft-high, or more; and this may be either a plain parapet, or baluftrade work ; and over the piers may be lodges of convenience for many purpofes ; but this muft be determined, not by fancy, but by the reft of the ftrufture. If the under part be plain, the parapet fliould be the fame: if the reft of the Bridge be more orname..'.ed, this may take alfo the fame turn of decoration. A Bridge of this conftruftion takes the lefs ornament, as the number of parts are fewer. Thus over each pier there may be a nich, in which to place a figure ; and there may run a cornice the whole length on each fide. This will be a very great article of elegance, and is fupported by the antique. We have mentioned the ends of the tranfverfe pieces, in fome wooden Bridges, being brought out for purpofes of ftrength and fervice» and have obferved a great advantage they would have this way in refembling the modillions of a cornice; but in thofe of ftone the cornice itfclf may be ufed with great propriety and beauty. We fee it in the Ar- minian Bridge, and that was a work of the Auguftan age, nay, of Au- guftus himfelf. It may not be amifs to trace in this Bridge, which is one of the moft elegant remains of Roman work in its kind, their idea of proportions, which the architecfl muft take care not to follow, unlefs where the circumftances are alike. The Bridge has five arches, and the three middle ones arc equal : the extent of each of thefe is twenty-five feet. The two others correfpond from the oppofitc fides, and their mealure is happily diminiftied by a fifth ; they are twenty feet each. All the arches are perfect lemicircles ; and their piers are in diameter half the height of the great arches with a fmall furplus. Thefe proportions we learn from this delicate remain, but this is not all we may learn from it. In fpeaking before in general terms of making the piers, we have di- redted that they in general face the ftream with a right angle. Thofe who have feen this in the moft admired works have thought to improve the form by making it an acute angle ; but in this the edge is weaker, and the whole too llight. The Romans knew what to attempt and where to flop ; in this elegant Bridge, as in many, nay, we might alnioft fay all the others of pure tafte, the pier meets the ftream in a right angle. Where the courfe of a river is rapid, fubjedl to be fwclled by Hood.-, and furious in thefe conditions; the beft method is to allow rather one large arch in the middle, than, as the elegant ftrudure of which we juft now fpoke, three equal. The piers of thele will break, difturb, and inter- rupt the courfe of the river, and the more the water is difturbed, the Z more S6 B R I mo'eimpetaoiis It becomes in all thefe inftances. But In obCerviiig thefe iiiftruftions, let not the young architedl run into excels: though there fliould he a confuierable difference between the central and fide arches in fuch a Bridge, yet this mud not be in fuch extravagance as to render the (ide arches ufelels. The decoration we propofcd for a ftone Bridge, has had place in this ; niches remain over the piers, in which the emperor who built the Bridge placed llatues of the heroes and the geniufes of the age; thofe who de- fended and adorned their country : but there fucceeded ages like to ours, ages which, producing no more fuch men, looked on the memorials of valour and of wildom as reproaches ; and left for barbarifm to deftroy. Of dividing the water. The main body of ihe river, muff be allowed to keep its couife in the midft, and the great arch is defigned to give it pafTage. But letour ftudent look into nature, and he williee that where- ever there is this violent force in the. body of a flreani,, there is a ripling current alfo at the fides. This let him cqnlider in the.con'ftrui^ion of the Bridge. As we propole the arches the courfe will be thus ; the main body of the water with its full force will pour uninterrupted tti rough the oreat arch, and thefe two fmaller currents of the fides will alio have their proportioned arches ; they will be divided from t,l;3e main current by the piers, and this without moleftation or interruption ; and as they run free, the main body will receive no change in its condition. This we propofe, and this will be the cafe in a well conftrudted Bridge j and in this way even the furious body of the ftream. being undillurbed, will run off evenly. But if this dir^dtion be carried to excefs, and the fide arches be made very fmall, the confequence will be worle than it there were none fuch. In that cafe the bcdy of water would only be too much, huddled together : and in this it w.uld be thus collected and diftincl at the fame time. Thefe fmall arches wou'd take their (liare, fuch as it was, while the river kept its common depth and bignefsj but as it rofe and fwelled, they would be incapable of receiving or pafTing that due proportion : there would be all the confiidl of difturbed and uninterrupt- ed water at the pieis ; and the main body, increafed by the addition of what fhould have gone off in thefe fide ftrcams, will be thrown into new fury and contufion, juft at that place where all the labour of the ar- chitect fliauld have been joined with all his ikill to give it quicknefs j tliat is, under the main arch ot the Bridge, From thefe confiderations, let him learn the neceffity of a juft divifion of the fpaceand proportion of the arches ; and if ne would add example to the precept, let him examine from the practice ot others in celebrated ages, and in the climes where his great fcience ilourilLed, what fuits the puipofe. We fhall carry him back to Italy. Over B R I 87 Over the BacchigHone, near the church of Saint Mary, Is a Bridge of this kind : it is a mixed work, antique in part, but finifhed by a hand more modern. The river is fuch as we have defcribed ; the Bridge of three arches, and of thefe one is pure antient Roman, as are the piers of all The river, full or low, rapid or calm, is carried with a happy freedom through thefe arche? ; and their proportion is this : the mealure of the principal or central arch i thirty-two feet, that of the two others twenty two and a half. The piers are in thicknefs one fixth ot the great arch. Here the piers are ftrong enough not only to fupport all weights that may come over the Bridge, but they alfo refill the fury of the waves in the greateft floods ; and while they ftand the force of the torrent, do not too much interrupt iis courfe: the whole bed of the river is divided as nature diftates into tliree parts, and the full quantity of the fide currents being taken off, the great body which rolls along the midft moves freely. Various circumftances may require that the architedl alter thefe pro- portions ; and he muft comply with fuch neceflity, only remembering, that as truth lies here, the lefs his deviations are, the better. Here is an inllance of propriety, and we have leleded it, becaufe It is, more thaa others, adapted to a middle courfe of things, and to general ufe. Of Bridges uithout decoratioua. In tiie eredtion of Bridges, a' well as houfes, v\ithout decoration, proportion will ftand in the place of ornament: we fhall lee this very conlpicuoufly in fome of thofe old Bridges where their great builders deligned ft:rength, and had no thought of decorations. The Bridge over the Reronc at Vicenza, which, from us nearnefs to the flefh -market, has obtamed the name 01 the But- clier's Bridge, is of this kind, and deferves to ftand as a model in like circumftances for thofe built at the expence of the public, and intended only for real ufe. In the more cxpenfiveand more decorated buildings, of whatever kindy the architedl has the fiee fcope for his fancy, and the means of greateil honour, but it is in the plain and fimple kinds that he mult ufe all his fkill ill the proportion ; and thefe will never fail to give him equal credit in the eyes 01 the jud cious. We named on this occafion the plain Vi- cenza Bridge, of which it Is not in the intent of our work to give a fi- gure, for what we propofe are new defigns ; not the repetition of plates every traveller has rendered cheap and common. In this where©! we now fpe k there are, as in the preceding, three arches, a larger in the centre, and on each fide of it a fmaller ; the compafs of the arch Is lefs than fe- micir.T the paiTage, and to thrufl over again to afF-rd a oaiTage ; and others, which open in the middle, half of which turns awny to one fide, and the other half to the other; being joined a- gain at plealurc : but they have this inconvenience, that one halt of them remains on the enemy's lide, F!\itig- Briuge, is an appellation given to a Bridge made of pontoons^ leatht, -boats, hollow beams, c Jks, or the like, laid on a river, and co- vered with pianks, for the paflage of an armv : it more particularly de- notes a Bridge compofed of one or two boats joined together by a fort of flo'-ring, and furrounued with a rail, or baliuftrade; having alio one ©r m; re mart-, to which is faftened a cable, fupported, at proper diflances,., by boats, and exten; ed to 'n anihor, to which ths other end is faftened, in the middle of the water: by wh.ch contrivance, the B .dge be- comes moveable,, like a pendulum, from one fide of he nvtr to the' otier, without any other help than the rudder Such Bndg s (ometimes al'O CO fift of two ftorics,. for the quuker pafi". ge of a great number of' men, or that bom infantry and cavalry may pals at the fame time,. A, a. Ti^c. \ 90 B U -F The Fioating-BriJgr, is fimilar to the Flying-bridge, being ordinarily made of two fmall Bridges, laid one over the other, in fuch a manner, as that the uppermoft ftretches and runs out, by the help of certain cords running through pullies placed along the l]des of the under- bridge, which pufh it forward, till the end of it joins the place it is defigned to be fixed on. When tbefe two Bridges are Ihetched out to their full-length, foi that the two middle ends meet, they are not to be above four or five fa- thoms long ; becaufe, if longer, they will break. Bridges of BoafSy.axe. either made of copper, tin, or wooden boats* faftened with ftak.es, or anchors, and laid over with planks. One of the moft notable exploits of Julius Cajfar, was the expeditious making a Bridge of boats over the Rhine. There are fine Bridges of boats at Beaucaire and Rouen, which rife and fall with the water, and one at Seville is faid to exceed them both. The Bridge of boats at Rouen, built in lieu of the ftately ftone Bridge eredled there by the Romans, is reprefented by a modern writer as the wonder of the prefent age. It always floats, and rifes and falls with the tide, or as the land waters fill the river. It is near three hu'idred yards long, and is paved with ftone, juft as the ftreets are; carriages with the greateft burdens go over it with eafe, and men and horfes with fafety, though there are no rails on either fide. The boats are very firm, and well moored with ftrong chains, and the whole well looked after, and conftantly repaired, though now very old. Broad-Stone, is the fame with free-ftone ; only this is fo called, becaufe raifed broad and thin out of the quarries, viz. not more than two or three inches thick. The ufe of this lort of free-ftones, which are called Broad Stones, is for paving court-yards and pafTages, and before fliop-doors, as in walks or paths in the city of London, to feparate them from the highway. But fome of thefe ftones are cut into perfeft fquares, like paving tiles, but much larger, as eighteen, twenty, or twenty-four inches fquare or more ; but as thefe are neater, fo they are dearer. Brow- Post, among builders, the beam that goes acrofs the building. Brown (Spanifti) is a dulTcy colour, with a reddilli caft. It is an earth that is dug out of the ground. It is of great ufe among painters j, being cheap and plentiful, and a colour that works vvell, if ii be ground fine, uhich may be done with lefs labour, than fonie better colours re- quire. T hat which is of the deepeft colour, and the Ireeft from ll:ones is the beft. The other forts are not fo good to give a colour to the eye, but yet they ferveas well as any other for the priming colours, to feaibn the wood to lay other colours upon. Buffet, a little apartment, feparated from the reft of the ropm, by flender wooden columns for placing China and glafs ware, &c. The Buffet among BUI 91 among the Italians, called Credenza, is inclofed within a baluftrade, elbow-high. Building, is ufed to fignlfy the art of conftrucfling and rajfing an edi- fice, in which fenfe it comprehends the expences, as well as the invention and execution of the defign. In the art of Building, convcniency, fiim- nefs, and pleafure, are to be confidered ; and thefe Sir Henry Wotton confiders under two heads, the fituation, and the work. As to the fituation, either that of the uhole is to be confidered, or that of. its parts. In the firft, regard muft be had to the quality, tem- perature, and falubrity of the air ; to the quality of the foil ; to the con- veniency of water, fuel, cariiage, &c. and to the agrecablenefs of profpccl. As to the fituation of the parts, the chief rooms, ftudies, and libraries, fixould lie towards the eafl ; thofe offices which require heat, as kitchens, b.rew-houfes, bake-houfes, and diftillations, towards the fouth ; thoie that require a cool, frefh air, as cellars, pantries, and granaries, to the north f as alfo galleries for paintings, mufsums, &c. which require a fleady light, .The ancient Greeks and Romans generally fituaied the fronts of their houfes towards the 'fouth, but the modern Italians vary very much from this rule. And indeed it is abfolutely necelfary to have regard to the country, each being obliged to provide againfl its own in- conveniences. The fimple forais of Building are either circular or angular. The circular form is very commodious, and the mod: capacious of any, ftrong, durable, and very beautiful; but is the mod chargeable of all others, and much room is loft by the bending of the walls, when it comes to be divided into apartments ; befides an ill diflribution of the lights, unlefs it be from the center of the roof. For thefe reafons, the antients em- ployed this form only in their te;pples and. amphitheatres, which had no need of compartitions. As for angular forms, Building neither lowes many nor few angles. The triangle is condemned above all others, as wanting both capacioufnefs and firmnefs, as alfo en account of its not being refolvable; in the internal partitions, into any other figure than its own. Buildings with five, fix, or more angles, are more fit for fortifi- cations than civil edifices. The redtangle, therefore, is generally cholen, as being a medium between the triang-le, and the pentagon,. &c. As;to a mixed fqrm, partly circular, and partly angtdar, a judgment may be made of them, from what has-been already faid of fimple ones. Let the builder, however, remember not t9 jofe fight of unifprmi,t){, vylyle he is in purfuit of variety. =, \-,y i . : ^ , ,^[.,r; , .'• ■ The acqeffories or ornaments of a Building are fetched , from fculptare and painting. In the firft, care ought to be taken 'that there be not tuo much of it, efpecially ai the entrance j and that both in fine and coarle pieces 92 BUT pieces of fculpfure, and likewife in placing figures aloft, the 'rules of perfpedive be ftriftly obferved. '^^ In pointing, the chief things to be regarded are, that the befc pieces be placed in the beft h'ghts ; and that they be fuited to the intention of the rooms they atre u'ed in. Bulk Heads, in naval architedlure, certain partitions built up in dif- ferent parts of a fhip, either acrofs dr lengthwife, to form and feparate the various apartments. i' Bullf.n-Nails, are a fort of Nails with routid heads, and fliort /hanks, lined and lacquered; there are feveral fjzes of them. They are ufed in han^-ing rooms, fetting up beds, covering of fliobls,' chairs, couches^ defks, coffin?, &c. '''"' ' Bust, or Busto, in fculpture, &c. the figure or portrait of a perfon in relievo, fliewing only the head, fhoulders, and flomach, the arms be- ing lopped off: it is ufually placed on a pedeftal or confole. Feliobiea obferves, that though in painting, one may fay, a figure appears in Bufto, yet it is not proper to fay, in a Buft. The Bull is the fame with that the Latins called Herma, fr6m' the Greek Hermes, Mercury, the image of that God being frequently repreiented in this manner by the Athenians. Bufl is alfo ufed, elpecially by the Italians, for the. trunk of a human body, from the neck to the hjps. BuTMENTS, are thofe fupporters or props, on or againft which the feet of arches refl. Alfu little places taken out of the yard or ground- plot of a houfe, for a butlery, fculleiy, &c.- ■ Buttery, a room in the houfes of noblemen and gentlemen belong- ing to the butler, where he depofits the utenlils belongnig to his office^ as table-linnen, napkins, pots, tankards, glaffes, lalvers, &c. As to its pofition, Sir Henry WottoTi" fays, it ought to he placed on the north fide of the building, which is defigned for the offices. In England, it is generally near the cellar, viz. the room commonly on the top of the cellar ffairs. Buttock, in naval architedure, the round parts of a fliip behind, under the flern, terminated by the counter above, and the after-part uf the bilge below. Buttress, a kind of butment built archwife, or a mafs of flone, or brick, ferving to prop or lupport the fides of a building wall, 6cc. on the cutfide, where it is cither very high, or has any conliderable load to f uflain on the other fide, as a bank of earth, &c. 1 hey c.re aifo ulcd againft the angles of lleeples, and other buildings of flone, &cc. on th ir outlioe, and along the walls of fuch buildings as have great and heavy rods, which would be fubjcft to thiuit the walls out, it tncy weic not thick, il no Buttrcfles were placed agaujft them. Buttrejfst C A B 93 BtiitrefcSt are alfo placed for a fupport and liutment, againft the feet of fome arches, that are turned acrofs great halls in eld palaces, abbeys, &c. and generally at the head of ftoiie buildings, when there are lirge crocket winaows ; and they are alfo placed for butmcnts to the arches of thefe windows. , , The. iheory and rules of Buttrefles are one of the defiderata in arch'tec- ture ; but it is not improbahle, but that a fagacious architedl and mathe- nutici n, who would apply himfclf diligently to examine into the mat-- ter, (. ight bing it within the bounds of reafon and rules, whereby it mipht be known very near, of what lize, and confequently what weight, a burtrels or butment ought to be j which mull: be various, according to the dimenlions and form of tne arch, and the weight which is fuper- incumbent on jt. Astoth. wf^i^^htof the materials, both on the arch, and in the but- trefs or butment, it is not difficult to calcu ate. But it may probably be objedted there luav be a lenlible difference to the ftrength and goodnefs of the bui^rels or butmcnts. Dr. Hork pro effor of geometry in Grefham College, in his Treatife of Hcliolcopes, promifed topublifla Ibmething to the purpofe aoovemen- tioned, but whether he did, 1 know not ; but what he promifed in that treatife. was a«- foUows, viz. a true mathematical and mechanical form of all manner ot arches, with the true butment neceffary to each of them, a problem, fays he, whjch no architectonic writer has ev^r yet attempted, much Icfs pertormcd. A treatife of this nature v/ould be extremely ufe- ful, for the want of a certain rule in arching, with its neceffary butment, has often pr ved the ruin of fome ftrudures, which have been of noincon- liderableexpences, as bridges, 6cc. C. CABIN, in naval architediire, an apartment in a fhip for any of the officers to eat, drink, and fleep in. 1 he great Cabin is chiefly in- teih^ed ior the captain cr princip.;! officer; but there are befides thefe fe- vcral of a fir.aller kind for the inferior officers. The bed-places of the failors, if they are built up at th^ ihip's-fide betv/een decks, which is often th... cafe in the merchant ihio?, are likewife denominated Cabins.

Caliber, an inftrumcnt ufed by carpenters, joiners, and bricklayers, to fee whether their work be well fquared. Caliducts, a fort of pipes or canals, difpofed along the walls of houfes and apartments, ufed by the ancients for conveying heat to feveral remote parts of the houfe, from one common furnace. Calotte, in architedure, a round cavity, or d-^prefllurc, in the form of a cap or cup, lathed and plaiflered, ufed to diminifti the rife or eleva- tion of a moderate chapel, cabinet, alcove, &c. which, without fuch an expedient, would be too high for other pieces of the apartment. Calquing, or Calking, a term ufed in painting, &c. where the backfide of any thing is covered with a black or red colour, and the ftrokes or lines traced through, on a waxed plate, wall, or other matter, by paf- ling lightly over each ftroke of the defign with a point, which leaves an imprefTion of the colour on the plate or wall. Camaieu, alfo a term in painting when there is only one colour, the lights and (hades being of gold, or on a golden and azure ground. It is chiefly ufed to reprefent baflb relievos. Camber-Beam, a piece of timber in an edifice, cut arching, or arch- wife, or with an obtufe angle in the middle, commonly ufed in plat- forms, as church leads, and on other occafions, where long and ftrong beams are required. A Camber-Beam being much ftronger than another of the fame fize, and being laid with the hollow fide downwards, (as they generally are) they reprefent a kind of arch. Cambring. The feamen fay a deck lies Cambring, when it does not lie level, but higher in the middle, than at either end. Cames, the fmall flender rods of caft lead, of which the glaziers make their turned lead. For their lead being caft into flender rods, of twelve or fourteen inches in length, are called Cames ; and fometimes they call each of thefe rods a Came, which, when it has been afterwards drawn through their vice, makes their turned lead. Cant, a term ufed by fome carpenters of a piece of timber j when it comes the wrong way in their work, they fay, Cant it, /. c. turn it about. Cant ALi VERS, pieces of wood framed into the front or other fides of the houfe, to lufpend the mouldings and caves over it. They feem, in- deed, to be the fame with modillions, except that the former are plain, and the latter carved : they are both a kind of cartouches, fet at equal diftances under the corona of the cornice of a building. Can TON ro, in architecture, is when the corner of a building is adorned with a pilaftcr, an angular column, ruftic quoins, or any tiling that projtdts beyond the wall. Cant- CAP 95 Cant-Timbers, In fliip building, thofe timbers, or ribs of the fliip which are fituated afore and abaft, or at the two ends where the flifp grows narrower below. Capital, (of caput, lat. the head) the uppermoft part of a column or pilafter, ferving as the head or crowning, placed immediately over the fhaft, and under the entablature. The Capital is the principal and efTential part of an order of a column or pilafter, and is of a different form in different orders, becoming the diftinguiftiing charadteriftic between them. Vitruvius tells us, that Gal- limachus, an Ingenious ftatuary of Athens, invented the firft regular ca- pital from the following accident. An Athenian old woman happening to place a bafket covered with a fquare tile over the root of an acanthus, which grew on the grave of a young Corinthian lady, the plant l!hooting up the following fpring, encompafled the bafket all round, till meeting with the tile it curled back in a kind of fcrolls. The above fculptor paf- fing by, and obferving it, executed a Capital on this plan, reprefenting the tile by the abacus, the leaves of the acanthus by the fcrolls, and the baf- ket by the body of the Capital. The Tufcan Capital is the moft fimple and unadorned of all the reft; its members or parts arc four only, viz. an abacus j an ovolo or quarter round; a collarino or neck; and an aftragal ; the latter indeed properly belongs to the firft or (haft. The charadler which dillinguifties this Ca- pital from the Doric, 6cc. is, that the abacus is fquare and quite plain, having no ogee or other moulding; and that there are no annulets under the ovolo. Authors, indeed, vary a little with regard to the Tufcan Capital. The height of this Capital is the fame with that of the bafe, viz. one module, or femi-diameter. Its projedture is equal to that of the bottom of the column, viz. five-eighths of the module. The Doric Capital has three annulets, or little fquare members, under- neath the ovolo, inftead of the aftragal in the Tulcan, befides the abacus, an ovolo and a neck, all which it has in common with the former ; and a talon, cyma, or ogee, with a fillet over the abacus. Vitruvius makes the height of this Capital equal to half the diameter of the column below; and this height being divided into three parts; the firft goes to the neck, the fecond to the boultin, and the third to the uppermoit paw of the Capital. The Ionic Capital is compofed of three parts; an abacus, coniiftmg of an ogee ; under this a rmd, which produces the volutes or fcrolls, the moft effential parts of this Capital ; and at the bottom an ovolo or quarter round. The allragal under the ovolo belongs to the fliaft : the middle part is called the rind or bark, from its fuppofed refemblance to the bark of a tree, laid on a vafe, whole brim is reprelVnted by the ovolo, and • feeming '96 '' C A' R fedming to have been fhrunk up in dryihg, and to have been twlfted into 'ithe vohites. The ovolo is adorned with eggs, as they are lo^nttimes called from their oval form. ... '.' ' ' ' The height of this Capital, according to M.

CaRTONj CAR 99 Carton, or Cartoon, in painting, a deflgn drawn on flrong paper^ to be afterwards calked through, and transferred on the frefh plafter of a wall to be painted in frefco. Carton is alfo ufed for a defign coloured, for working in mofaic, tapeftry. Sec. The Cartons which were formerly at Hampton Court, but now at the queen's palace, are defigns of Raphael Urbin, intended for tapeftry. Cartouche, an ornament reprefenting a fcroll of paper. It is ufu- ally a flat member, with wavings, to reprelent fome infcription, device, cypher, or ornaments of armoury. They are in architedlure, much the fame as modillions; only thefe are fet under the cornice in wainfcotting, and thofe under the cornice at the eaves of a houfe. Caryatides, or Cariates, (focalled from the Caryatides, a peo- ple of Caria) are in architedlure, a kind of order of columns or pilafters, under the figures of women dreffed in long robes, after the manner of the Carian people, and ferving inftead of columns to fupport the entablement. Vitruvius relates the origin of the Caryatides. He obferves, that the Greeks having taken the city of Caria, led away their women captives ; and to perpetuate their fervitude, reprefented them in their buildings as charged with burdens, fuch as thofe fupported with columns. M. Le Clerc aptly enough calls thefe fymbolical columns, and tells us, that the antient Greeks had a cuftom, in the columns of their public buildings, to add figures and reprefentations of the enemies they had fubdued, to pre- ferve the memory of their victories. That they having reduced the re- bellious Carians to obedience, and led away their wives captives ; and that the Lacedemonians having vanquished the Perfians at Plata^a, they were the firft fubjeds of thefe columns ; which have preferved to late pofterity both the glory of the conquerors, and the diflionour of the conquerea. And hence originally came the names Caryatides, and Perfian columns; which names have been fince applied to all columns made in human fi- gures, though with characters very different from each other. M. Le Clerc likewile obferves, that the Caryatides are not now repre- fented among us, as they were among the antients, viz. as fubjedls of fer- vitude and flavery, with hands tied before and behind, fuch charaders feeming injurious to the fair fex ; and for that reafon wc give rhcm others entirely oppolite, never ufing them in building but as lingular beauties^ and fuch as make the greateil: ornament thereof. Among u.^, they are re- prefented under the noble fymbols, or images of Juftice, Prudence, Tem- perance, &c. The Caryates fliould always have their legs pretty clofe to each other, and even acrofs, or the one athwart the other, their arms laid Hat to their bodies, or to the head, or as little fpread as polfible ; that as they do the office of columns, they may as near as pollible bear the figures of them,^ When the Caryatides are infulated, they fhould never have ary great weight lOD CAR welf^ht to fupport, nor greater than thofe of balconies, little galleries, or flight crownings, and their entablature and pedcftal are not to bethought io proper to bear great loads. If the Caryatides have aprojecfture beyond the wall, in the manner of pihifters, they may be ufed in the architedure of a gallery or falon, provided they may be not made to fuftainany thing but an entablature, the weight of the vault being borne by the wall be- hind, which ferves them as aground or bottom. The Caryatides ought always to appear in charadlers proper to the places they are ufed in. For inllance, thofe which fupport the crowning of a throne, {hould be (^mbols, or reprefentations of heroic virtues. Thofe which are let in a place of devotion, fhould bear the charadlers of religion, and thofe in halls and banqueting-rooms, fliould carry the marks of mirth and rejoicing. Caryat'des, and common columns, fhould never be ufed together un- der the fame entablature ; for beiides that, there can never be a juft fym- metry between them. The figures of women, as tall as common co- lumns, would appear monflrous, and make all the reft of the architefture appear low and mean. Again, the Caryatides fliould neverbe made of an immoderate Ifature ; left being too large, they might become frightful to ladies; and for this rcafon, one would chufe to confine them ibmetitnes under the impofi: of a portico, fuch impolls ferving them for an entabla- ture. They may aUb upon occafion be railed upon pedeftals, which ougKf not to be lower than one third of their height : and befides this, if there be confoles placed over their heads, the figures may be made of a reafon- able height. Sometimes the arms of the Caryatides are cut off for the greater deli- cacy, as thofe for inftance in the halls of the Swils guards in the Louvre, But M. Le Clerc does not approve of fuch mutilations. Thefe kinds of mutilations, which are only uled to make the figures more light and de- licate, cr rather to make them more conformable to the columns, are on- ly proper for termini, or forms, which arc a kind of half human figures, leetning to proceed out of a vagina or iheath. The Caryatides are fometimes reprefented in the form of angles ; which, M. Le Clerc is of opinion, fhould not be, except at baldaquins, and al- tars. And fuch as do appear under that holy form, ought, in his opi- nion, to fupport the entablature with their hands j or, as others fay, with their head?, as bearing it eafily and without trouble. The entablature fupported by angels, M. Le Clerc would have to be of the Corinthian order j and that by the virtues of the Ionic ; and both the one and the other fomewhat lefs mafTive than the ordinary. The antients made the Caryatides frequently to fupport corbels, or bafkets of flowers ; and thefe they call Canifera: and Cilliterge. Casement, CAS loi Casing of timber-work, is the plaiftering a houfe all ever on the out- fide with mortar, and then ftriking it wet by a ruler, with the corntr uf a trowel, or the like inllrument, to make it refemble the joints of tree- ftone ; by which means the whole houfe appears as it built thereof. As to the method of doing it: fome dirett it to be done upon heart- laths ; becaufe that the mortar would in a little time decay fip-laths : and although it will require more labour to lath it with heart, than with fap laths, yet it will be better for the mortar to hang to, becaufe heart- laths are the narroweft ; and laths ought to beclofer together for mortar, than for loam. They alfo fay, that they commonly lay it on in two thicknefTes, viz. a fecond before the firft is dry. Casement, a name given by fome workmen to the fcotia, or hollow moulding between the two torus's in the bafe of columns : which loms architedls make one fixth of a circle, and others one fourth. The fame word in its common fenfe exprefles the opening of a window ; and in mi- litary architediure a vault ot mafons-work in that part of the flank of the baftion next the curtain. Casting, among fculptors, the taking carts of impreflions, of figures, bufts metals, leaves, 6cc, The method of takmg of carts of figures and hurts, as at prefent prac- tifed, is moll generally by the ufe of plairter of Paris, or, in other words, alabafter calcined by a gentle heat. The advantage of uling this fubftance preferably to others, confilts in this, that notwithftanding a flight calci- nation reduces it to a pulverine rtate, it becomes again a tenacious and cohering body, by bemg moiftened with water, and afterwards fuffered to dry ; by- which means either a concave or a convex figure may be given by a proper mould or model to it when wet, and retained by the hardnefs it acquires when dry: and from thefe qualities, it is fitted to the double ufe of making both carts and moulds for forming thofe carts. The plairter is to be had ready prepared of thofe who make it their bufincls to fell it ; and the only care is to fee ttiat it is genuine. The particular manner of making carts depends on the form of the fubje^t to be taken. When there are no projedling parts, it is very fimple and ealy: as like- wife where theie are Inch as form only a right, or any greater angle with the principal furface of the bod\ : but where parts projcdl in leff^it angles, or form a curve inclined towards the prmcipal iuilace of the boiiy, the work is more difficult. The fir ft rtep to be taken is the forming the mould ; which is, indeed, done by much the fame means as the cart is afterwards made in it. In order to this, if the original or model be a bais relief, or any oiher piece of a flat form, having its furface frii; well greafed, it muft be placed on a proper table, or other luch fupport, and lurtounded by a frame, th-e fides of which muft be at fuch a diftance horn it, as will allov/ a prop'jr D d thicknefs 102 GAS thicknefs for the fides of the mould. A due quantity of the piaifter, that is, what will be fufficient to cover and rife to fuch a thicknefs as may give fufficient ftrength to the mould, as alfo to fill the hollow betwixt the frame and the model, muft be moiftened with water, till it be juft of fuch confiftence as will allow it to be poured upon the model, which fliould be done as foon as poflible : for it muft not be delayed after the water is added to the piaifter, which would otherwife concrete or fet, fo as to be- come more troublefome in the working, or unfit to be ufed. The whole muft then be fuffered to remain in this condition, till the piaifter has at- tained its hardnefs ; and then the frame being taken away, the preparatory caft or mould thus formed, may be taken off from the fubjedt entire. Where the model or original fubje(fl is of a round or eredt form, a dif- ferent method muft be purfued ; and the mould muft be divided into feve- ral pieces: or if the fubjed; confifts of detached and projecting parts, it is frequently moft expedient to caft fuch parts feparately ; and afterwards join them together. Where the original fubjedt or model forms a round, or fpheroid, or any part of fuch round or fpheroid, more than one half the piaifter muft be ufed without any frame to keep it round the model ; and muft be terri- pered with water, to fuch a confiftence, that it may be wrought with the hand like very foft pafte : but though it muft not be fo fluid as when pre- pared for flat figured models, it muft be as moift as is compatible with its cohering futficiently to hold together : and being thus prepared, it muft be put upon the model, and comprefled with the hand, or any fiat inftrument, that the parts of it may adapt themfelves, in the moft per- fedl manner, to thofe of the fubjed, as well as be compadt with refpedt to themfelves. When the model is fo covered to a convenient thicknefs, the whole muft be left at reft till the piaifter be fet and firm, fo as to bear dividing without falling to pieces, or being liable to be put out of its form by flight or violence ; and it muft then be divided into pieces, in o-^der to its being taken off from the model, by cutting it with a knife with a very thin blade J and being divided muft be cautiouQy taken off, and kept till dry: but it muft be always carefully obferved, before the leparation of the parts be made, to notch them crofs the joints, or lines of the divifion, at proper uiftances, that they may with eafe and certainty be properly con- joined together ; which would be much more precarious and troublefome without fuch diredlive marks. The art of properly dividing the moulds, in order to make rhem leparate from the model, conftitutes the greateft object of dexterity and fkill in the art of calting ; and does not admit of rules for the moft advantageous conducft of it in every cafe. But we Ihall endeavour to explain the principles on which it depends, in fuch a manner, that by a due application of them, all difhculties may at any time be fur- mounted. J C A S 103 mounted, and an expertnefs, even of manner, acquired by a little prac- tice. With refpe(5t to the cafe in queflion, where the fubjedl is of a round or f'pheroidal form, it is heft to divide the mould into three parts, which will then eafily come off from the model : and the fame will hold good of a cylinder, or any regular curve figure. The mould being thus formed, and dry, and the parts put together, it muft be firft greafed, and placed in fuch a poiition, that the hollow may lie upwards, and then filled with plaifter, commixt with water, in the fame proportion and manner as was directed for the carting the mouldj and when the caft is perfedlly fet, and dry, it mufi: be taken out of the mould and repaired, where it is neceflary ; which finilhes the whole operation. This is all that is required with refpedl to fubjedls where the furfaces have the regularity above-mentioned : but where they form curves, which in- terfedl each other, the conduit of the operation mufl: be varied with re- fpedt to the manner of taking the caft of the mould from the fubjedt or model J and where there are long projediing parts, fuch as legs or arms, they (hould, as was obferved before, be wrought in feveral cafts. In the fame manner figures, bufts, &c. may be cart: of lead, or any other metal, in the moulds of plaifter : only the expence of plaifler, and tedioufnefs of its becoming fufficiently dry, when in a very large mafs, to bear the heat of melted metal, render the ufe of clay, compounded with fonie other proper materials, preferable where large fubjedts are in queftion. Cads of medals, or fuch fmall pieces as are of a fimilarform, maybe made in plaifter, by the method directed for bafs relievos. Indeed there is nothing more required than to form a mould by laying them on a proper board ; and having furrounded them by a rim made of a piece of card, or any other pafte-board, to fill the rim with loft tempered plaifler of Paris; which mould, when dry, will ferve for feveral cafts. It is never- thelefs a better method to form the mould of melted fulphur ; which will produce a (harper impreffion in the caft, and be more durable than thofe made of plaifter. The cafts of medals are frequently made of fulphur, which being melted, muft be treated exadtly in the fame manner as the plaifter. Calts may be made likewife with iron with very little additional trouble, provided it be prepared in the following manner. " Take any iron bar, or piece of a fimilar form ; and having heated it red hot, hold it over a veftel containing water, and touch it very flightly with a roll of fulphur, which will immediately difiolve it, and make it fall in drops into the water under it. As much iron as may be wanted being thus diflblved, pour the water out of the veftel; and pick out the drops formed by the melted iron from thole of the fulphur, which con- tain little or no iron, and will be diftinguifhable from the other by their colour and weight." Tlic 104 C A U The iron will, by this means, be rendered fo fufible, or eafy to be melted, that it will run wth lefs heat than will melt lead, and may be employed for making carts of medals, and many other fuch purpofes, with great convenience and advantage. Cafimg in joinery, &c. "Wood is faid to cafl: or wnrp, when either by its own drought, or moirture of the air, or other accidents, it flioots or fhrinks, and alters its flatnels and flraightnefs and becomes crooked. Catacomb, a grotto or Jubterraneous place for the interment of the dead. The term is particularly ufed in Italy for a vaft affemblage of fub- terraneous fcpulchres three leagues from Rome, in the Via Appia, fup- pofed to be the fepulchres of the antients. Each Catacomb is three feet broad, and eight or ten high, running in the form of an alley or gallery, and communicating with each ( ther. CatadromEj an engine like a crane, ufed by builders in raifing . weights. Cat-head, in naval architecSlure, a large fquare piece of timber; one end of which is fattened upon the fore-cafth, and the other end projedts without the bow, fo far as to keep the anchor clear of the fhip when it is drawing up by a tackle. nds, or at moft but very little higher. As to the fituation of Cellars, Sir Henry VVotton fays, they ought, unlefs the whole houfe be cellared, to be fituated on the north- fide of the houfe, as requiring cool and fre(h air. Cellars are ulually dug by thefolid yard, which contains twenty feven folid feet; and therefore the length, breadih, and depth being multiplied together, and the prod u(fl divided by twenty-fevcn, the quotient will give the content in folid yards. Cement, or C-iEMent, in a general fenfe, any glutinous fubftance capable of uniting and keeping things together in clofe cohelion. Cenientf in architecflure, a ftrong fort of mortar, uled to bind or fix bricks or (lones together, for fome kind of mouldings ; or in cementing a block of bricks; for the carving of capitals, fcrolls, or the like. It is of two forts, one called hot Cement, and the other cold Cement ; be- caufe the hot Cement is made and ufed with fire j and the cold Cement is made aid ufed without fire. To make the hot Cement, take of bets-wax two pound, and of refm one pound ; mix them, and add one pound and a halt of the fame pow- dered, as the body to be cemented is compofed of, Itrewing it into the melted mixture, and flirring them well together ^ and atterwards knead- ing the nuls in water, that the powder may be thoroughly incorpcrated with the v/ax and refin. The proportion of the powdered matter may be varied, where required, in order to bring the Cement nearer to the co- lour of the body on which it is employed. This which forms an excellent llrong Cement, mult be heated when applied; as mull; alfo the parts of the lubjedt to be cemented t- gether ; and care mufl: be taken likewife that they are thoroughly dry. Where a great quantity of Cement is wanted for coarfer ufes, the coal-afli mortar, or Welch terras, as it is called, is the cheapell and belf, and will hold extremely well, not only where it is conltantly kept wet, or dry; but even where it is fometimes dry, and at other times wet; but where it is liable to be expofed to wet and froft, it fhould, a: its being laid on, be E e iuttered io6 C H A fiifFered to dry thoroughly before any molfture can have accefs to it ; and, in that cafe, it will likewife De a great improvement to temptr it with the blood of any beaft. This mortar, or Welfii terras, muil be formed of one part lime, and two parts of well fifted coal-aflies; and they muft be thoroughly mixed by being beaten together ; for on the perfedl mixture of the ingredients, the goodnefs of the compofition depends. Where the Cement is to remain continually under water, the true terras is commonly ufed, and will very well anfwer the purpofe. It may be formed of two parts of lime, and one part of plaifter of Paris, which fhould be thoroughly well beaten together, and then ufed immediately. For the fixing fliells, and other fuch nice purpofe?, putty is moif ge- nerally ufed J but it may be formed of quick lime and drying oil, mixed with an equal quantity of linfeed oil ; or, where the drying quicker is not necellary, it may be made with lime and crude linfeed oil ; w^ithout the drying oil. Refin, pitch, and brick-duft, in equal parts, melted together and ufed hot, are much the cheapeft Cement for (hell Vv'ork, and 'vill perform ihat office very well, provided the bodies they are to join together be perfedly dry when they are ufed. The cold Cement is lefs ufed, and is reckoned a fecret known but to few bricklayers. It is made after the following manner. Take a pound of old Chefhire cheefe, pare off the rind and throw it by, then cut or grate the cheele very fmall, put it into a pot with a quart of cow's milk ; let it ftand all night, and in the morning, take the whites of twenty four or thirty eggs, and a pound of the beil unflacked or quick lime, and beat it in a mortar to a very fine powder, fitt it in a fine hair fieve, put the cheefe and milk to it in a pan, or bowl, and ftir them well together with a trowel, or fuch like thing, breaking the knobs of the cheefe, if there be any, then add the whites of eggs, and temper all well together, and it will be fit for ufe. The Cement will be of a white co- lour ; but if you will have it of the colour of brick, put into it either fome very fine brick-dulf, or fome almegram, juft fufficient to give it a colour. Chamber, in a houfe or building, any room fituate between the low- ermoll, excepting cellars, and the uppermoil rooms. So that there are in fome houles two, in others three or more floiies of Chambers. Sir Henry Wotton direds:, that the principal Chambers for pleafantnefs be lituated towards the eaft As to the proportions : the length of a well proportioned lodging fliould be the breadth and half of ttie lame, or fome fmall matter leis,^ but Ihould never exceed that length. As for the height, three-fourths of the breadth will be a proper height. Palladio diredls, that Chambers, anti-chambers and halls, either Hat or arched, Ihouid be made of the following C H A 107 following heights. If they are flat, he advifes to divide the breadth into three parts, and to take two of them for the height of the ftory from the floor to the joifl. In the building of Chambers, regard ought to be had to the place of the bed, which is ufually fix or feven feet fquare ; and the palTage, as well as to the fituation of the chimney, which, for thi? confideration, ought not to be placed jufi: in the middle, but diltant from it about two feet, or two feet and a half, in order to make room for the bed ; and by this means the inequality is hardly difcerned, if it be not in buildings of the breadth atleaftof twenty-four feet within the work; in this cafe, it may be placed exa(5lly in the middle. Chancel, a part of the fabric of a Chriftian church, between the altar and balluftrade that inclofes it, where the minifter is placed at the ce- lebration of the holy communion. Chandelier, in military architedure, a kind of moveable parapet, confifting of a wooden frame, made of two upright Hakes, about fix feet high, with crofs planks between them; ferving to fupport fafcines to cover die pioneers. The Chandeliers differ from blinds only in this, that the former cover the then only before, and the latter cover them alfo above. They are ufed in approaches, galleries, and mines, to hinder the workmen from being driven from their Nations. Channel, in architedfure, that part of the ionic capital under the abacus, and lies open upon the echinus or eggs, which has the centers cr turnings on every fide to make the volutes. Channel of the Larmier, the foffit of a cornice which makes the pen- dant mouchette. Channel oi the Volute, in the Ionic capital, the face of the circum- volution inclofed by a liftel. Chantlate, in building, a piece of wood faftened near the ends of the rafters, and projedting beyond the wail to fupport two or three rows of tiles, fo placed, to hinder the rain water from trickling down the fides- of the walls. Chaplet, in architedure, a fmall ornament carved into round beads,, pearls, olives, and pater- nollers, which is frequently done in banquettes. Charge or Overch4.rge, in pointing, an exaggerated reprefenta- tion of any peifon, wherein the likenefs is prefcrved, but withal ridiculed : few painters have the genius to fucceed in thcfe Charges. The method is, to pick out and heighten lomething amifs in the face, v/hether by way of defed or redundancy ; thus, if nature has given a man a nofe a little larger than ordinary, the painter falls in with her, and makes the nofe extravagantly long; and fo in other cafes. This is alfo called caricature. Charnel, or Charnel-house, a kind of portico, or gallery, ufually in or near a church- yard, over which were anciently laid the bones of the dead,. jo8 CHE dead, after the fleili was wholly confumed. Charnel-houfes arc novr ufually adjoining to the church. CiinsNtiT. The Horfe-Chefnut, fays a certain author, ought to be -aniverfally propagated, being eafily increafed from layers, and grows in large ftandards, bearing a mofi: excellent flower j it is much ufed for ave- nues in France, and was brought into tbefe parts of Europe from Tur- key, and lias been raifed from nuts brought from thence j wiiich grow jvell with us, and in time to fair large trees, full of boughs and branches, ■green-leaved, and Areakedon the edges; with threads in the middle, that in their native country turn to Chefnuts, but rarely with us. It is valued for the hW green leaves and flowers ; and for want of nuts is propagated by fuckers : its name comes from the property of the nuts, which m Turkey are given to horfes for their provender, to cure fuch as have coughs, or are broken -winded. Mr. Chomel fays, that nothing fcems to him more agreeable, or that would bring more profit to a country, than Chefnuts planted in rows, well managed, and kept in good order; which would not only be pleafing to the eye, but the flower would be agreeable to the fmell, and the latle in time will alfo be gratified. Thefe trees are of quick growth, they flioot up in a little time, and their leaves, which are very beauiiiul, will form a fliade, which will invite people to retire under thein. In lune places he tells us, that Chefnut-trees grow like oaks, and make iureft- trees; they likewife plant them at a full dnlance one fr^.m tn- other, like young oaks for coppice and underwood ; b'jtthis is Jeldom done, as they are not good for burning, on account of their crackling in the fire, and their aptnefs to burn thecloaths of thofe who fit near it. As to the particular ufes of Cliefnut-timber, they are next to the oak, mofl coveted by carpenters and joiners; and formerly mofl of our houfes ic London were built of it, there having been a large forefTbf them not tar from this city in the reign of king Henry. It makes the befl flakes and pcles for pallifadoes, pediments for vine props and hops; it is alfo proper for mill timber and water-works It is fo prevalent againft cold, that Chefnut-trees defend other plantations from the injuries of the fevereft frofis. The Chelnut-tree is alfo proper for columns, tables, cherts, chairs, flools, bedfteads, and wine-calks, and thofe for other liquors, giving tiie liquor the leaft tindure of the wood of any whatfoever, and having been dipped in fcalding oil, or well pitched, is very durable, it will look fair without, indeed, when rotten within; however, the beams give warning of a fall of a houfe by their cracking. The coals of this wood are excellent for the fmith, foon kindled, and as foon quenched. Chevaux de Frise, a large jcift or piece of timber, about a foot in 4iaffieter, and ten or twelve feet in length; into the fides of which are driven CHI X09 driven a great number of wooden pins, about fix feet long, armed witlt iron points, and croffing one another. The chief ufe of the Chevaux de Frife, is to ftop up breaches, or to fecure the avenues of a camp, from the inroads both of horfe and foot. It is fometimes alfo mounted oa wheels, with artificial fires, to roll down in an afiault. Chimney, that part of a houfe where the fire is made, having a funnel to carry away the fmoke. . In moft things relating to building, we may refer the modern architect to the pradice of the ancients for models fiom which to work, and ex- amples by which -to improve ; but in this matter of Chimnies we have pot that refource. The accounts the antients give of them in their wri- tings are ftiort and trivial; and the rules of Vitruvius for conrtruaing them are full of oblcurity. Indeed they were lefs acquainted with them, be- caufe they had lefs neceffity for them; they lived in a warmer country than ours, and they had the ufe of ftoves ; fo that the conftrudhon of Chimnies was little regarded. With us the neceffity of them is abfolute, and the inconveniences that frequently attend them are fo great, that no- thing more effentially regards the profeffion of the architeft, than their proper conftrudtion and difpofitioii. Fires are neceffary, and we willi the fmoak to pafs free away : if^ this theeffed of the wind is very great; and to be fecure of every advantage in that refped, the builder is to have the danger of fmoak in his eye from the firft difpofnion of the building. Let him confider firft the nature of the region,' and from what quarter the winds mod frequently _blow, or moll furioufly : and let him, according to this confideration, difpoie the rooms that (liall have mofl: need of fires in places where thefe winds have leaft power. This is much earlier than builders ufually begin their pro- vifiun againft fmoaky Chimnies ; but their not taking the precaution in time is one of the principal reafons why the fault is lo difficult to be re- medied. He who ffiall have begun thus can have only the ill conftruftion of a Chimney to combat with in the attempt of remedying an error; he who has negleded it may have the difpofition of it, which is often im- poffible to alter. The common caufes of fmoaking are either that the wind is too much let in above at the mouth of the Ihaft, or the fmoke is ftified below ; and fometimes a higher building, or a great elevation of the ground behind is the fource of the mifchief. Finally, the room in which the Chimney is, may be fo little or clofe, that there is not a fufficient current of air to drive up the fmoke. When the archited: has thus acquainted himlelt with the feveral caufes of the fmoaking of Chimnies, he will know by what means he may mol\ rationally obviate fuch inconveniences ; and how- he may remedy the accident, where in fpite of all his care it ffiall hap- pen : when the caufe is not confidered, this is impolTible, and i! is no un- F f common J 10 C H I common tiling te fee much labour beftowed pcrfedly in vain, becaufe the fault is mifuiic'erftood. As fmoaking is the greateft inconvenience that can attend this p&rt of architevfture, we have fet out in this place with its caufes ; thefe we fhall now caution the architedl to obviate by a proper difpofition and proportion of his rooms, and a judicious conftrudlion of the Chimney itfelf. We have feen, that the two great caufes of the inconvenience are the fmoak's being driven back, or lingering in the funnel : the driving back is an ac- cident from w ithout j the lingering in the funnel is from fome error with- in^, either in the conftrudion of the funnel itlelf, or of the room where the Chimney ftands. The Chimney may be divided into two parts, the firft containing the opening, the hearth, and the funnel ; the other thejaumbs or fides, the mantle-piece which refts upon them, and what is called the Chimney- piece, which comes over the mouth. This is the common diftindtion, and according to this, the firft part is what concerns us, the reft ornament. Much depends upon the opening; if this be too fmall and low, the fmoak of itfelf naturally is checked at the firft (etting out, and miffing its way, returns into the room ; and on the contrary, if it be too large and high, the fame happen?, becaufe if there be too much room for the air and wind, the fmoak will by that be driven into the room. The proportions of Chimnies we fliall give hereafter, when we treat of their ornamental parts, and the rooms in which they are to ftand; here we are enquiring only into their general flrudure. The mouth of the Chim- ney, or that part which joins the back, (hould be fomething fmaller than the reft; for this will make a ftop againft the fmoak, when it fliall be coming down into the room i and meeting with that refiftance, it will of courfe return back : indeed the making the tunnel narroweft at bottom is a very great article in the preventing fmoaking, becaufe it affifts doubly; the fmoak getting the eafier up, as the fpace is all the way wider, and coming down with more difficulty as it grows narrower. Yet this pru- dent caution muft not be carried to an extreme, becaufe then the fmoak will linger in the upper part, and all the force of the draught below will not be fu.^cient to fend it up. Another very good method to affift the difcharge of the fmoak is the making two holes one over another in each fide of the Chimney ; one of thefe is to go Hoping upwards, and the other floping downwards, fo that the fmoak will always find way through one of them. The placing a moveable vane at the top of the Chimney is alfo ofien fuccefsful; this keeps the opening of the funnel fcreened againft the efforts of the wind, let that blow whTch way it will. To thele we may add two other con- trivances more ingenious than ufeful ; the one is the carrying up the fun- nel fpiral, to prevent the eafy defcent of the fmoak 3 and the other the hanging C H I III hanging the aeoliplle in the lower part of the Chimney, to drive it up by blowing. This asolipile is a hollow ball of brafs filled witli water, with a fmall opening in one part; this being hung up jufl: over the flame, blows forcibly out at the hole as the water heats. Thefe are the feveral methods commonly ufed for the remedying as well as preventing the fmoaking of Chimnies ; but let the judicious ar- chi'edl proceed upon the moft certain principles in obviating the danger. Let him obferve a due proportion between the fize of the room and that of the Chimney ; let him be careful to place the doors in fuch a man- ner, that they may mof^ favour the carrying up of the fmoak, and to give the fides a proper projeflion, and the back a due diftance. Chimney hooks, are hooks of fteel and brafs, put into the jaurnbs of Chimnies, into each jaumb one, for the handle of the fire-tongs and fire pan to reft in. Chimney jaumb?, are the fides of a Chimney, commonly ftanding out perpendicularly (but fometimes circularly) from the back, on the extre- mities '-f which the mantle-tree refts. Chimney-Piece, is a compofition of certain mouldings of wood or ftone, ftanding on the fore-fide of the jaumbs, and coming over the mantle tree. Of the general SiruSfure of Chimney-pieces and their fveral Materials. We are in nothing left fo much to the dictates of fancy, under the whole fcience of architedlure, as in the conftrudlion of Chimney-pieces. Thofe who have left rules and examples for other articles lived in hotter countries; and the Chimney was not with them as it is with us, a part of fuch eflential importance, that no common room, plain or elegant, could be conftrucfted without it. With us no article in a well-finiflied room is fo eflential. The eje is immediately caft upon it on entering, and the place of fitting down is naturally near it. By this means it becomes the moft eminent thing in the finiftiing of an apartment ; and, as fancy is to take the place of rule and example in its cunftruftion, nothing is more eflential thin to direct the young architecfl how he fhall employ this wild guide properly, on what occations he is to give the reins to imagination, and when it is to be limited by method. We (hall endeavour to lay before our readers all the variety that can properly be introduced, and every kind of allowable ornament, adding to thefe what may be tranlpofed from other parts in the antique ftrudlures, and upon what plan he may devife innumerable and unexceptionable de-* corations. We fhall firft confider the ftrudture of the part, and pafiing over the ilighter, reft upon the more worthy materials. The 112 C H I The fquare body of a Chimney, opened on one fide from the Iev^el cf a floor to a due height, for the convenience of making a fire, and the advantage of receiving its heat, gives the whole idea of the plain Chim- ney-piece: that is, a fquare aperture in one fide of the flrudlure with the raw bricks as edges. Thus it appears to us in the firfi: conftrudlion of rooms ; thus it appeared to thofe whom neceflity firll taught its ufe j and thus it ftands before the architedl to be finifhed. The form and dimenfions we have confidered among efl"ential parts ; and its decora,tion now comes into the regard among thole which are purely ornamental. To trace this matter from its origin, we fhall be led to the rife of the firfl: plain Chimney-pieces, formed as all other or- naments that have their foundation in a fenfe of utility, from the incon- venience of the part to be ornamented in its natural condition. The edges of a brick wall thus furnifhing the original chimney, would crum- ble and break off; and they would be inconvenient to thofe who fat near them, by their roughnefs and foulnefs. To take off this difagreeable look and inconvenience at once, a frame of wood-work was carried round it, a board on each fide, and a third at the top ; and this upper one, whofe thickncfs firfl feemcd as a ledge to hold things, gave rife to the mantle- • piece, now fo common and lb proper an ornament to the conllruiflion. The firft improvement was painting thefe boards ; and the next was- Aipplying their place with more proper, or more ornamental materials. Stone was fitter to be near a fire than wood, becaufe not liable to acci- dents of burning ; and the ufe of this fOon introduced that ot marble. The ftone Chimney-piece, while it banifhed the tear of fires^ renewed the other inconveniency of the original Chimney, though in a lels de- gree ; for tliough lefs foul than brick, it was not near fo cleanly as wood. Here marble fupplied the deficiency ; as fecure from fire as lione, and more beautiful and cleanly than wood. Offnnple and continued Ch imney-Pieces. Thus far the firft eflibrts of the rude architedure in early time carried the decoration of the Chimney. In after ages, a variety of marbles, ex- ceeding one another in beauty, took each other's place in magnificent apartments i and to thefe firll t!x Iculptor added the graces of his art 5 and afterwards the architeft, judging the conftruftion of the ornament not unworthy his molt ferious attention, enriched it with columns and their entablatures, till the workmanfhip eclipfed the befl materials. We fliall confider hereafter the variety of materials the ancients had for their greater purpoles, mofl: of which remain for our Icivice in thefe articles, and fhall then treat of the addition of ornament. In C H I •'3 In order to afcertain the propriety of the peculiar kinds of marble we fliall recommend, (for it is not every one we can recommend to the archi- te(5t for his purpofe,) we fliall firft confider the Chimney-piece as fuited to rooms of more or lefs elegance, by placing it befjre him in the two ge- neral conditions, fimple, or continued to the cieling ; by fimple, we mean a Chimney which terminates at its mantle-piece, or by a pediment, or other fuch ornament over it; and by this kind of Chimney, continued up to the cieling, we underfland an entire work finiOiing that part of the room, and confifting of the proper or fimple Chimney and ornaments above correfpondent to it in breadth, leaving a pannel for a pidlure, ter- minated at the heighth of the room, with fculpture, accommodated in nature and degree to that of the lower part. Thefe are the two general ideas the ftudent is to entertain of a Chim- ney-piece» Thofe kinds of marble may be very well fuited to one Chimney-piece, which may be altogether improper for the other; for in the continued Chimney-pieces we fhall give, for many purpofes the upper work is to be of wood or ftucco, plain or gilded ; and in all thefe cafes there are rales to be had, from its nature and intended furface, for the kind of marble which will be fitted for the work below. Of the various Ornaments of Chimney-Pieces, V/hen we have introduced the fludent to the firil diftindion and general divifion under which he is to regard this part of a room, we fhall con- fider the various ornaments of which each kind is capable. With refpedl to their appropriation and ufe, he will find that the fimple Chimney is befi: faited to a papered or plain room, or to one that has little additional de- corations ; the continued kind to thofe which have higher finifliings ; and he will find that the whole honour of this work will depend upon the fliiting this continued ornament to the reft of the finifliing. Both the one and the other are fufceptible of all the grace of ornament. We fhall afterwards treat of the dillindl kinds of decorations, which are proper to either in particular, or common to both, and fhew the ufe of columns and fimilar decorations. From thefe we fliall proceed to the introdu6l'.on of figures, the Caryatic or Perfian orders, &.c. Of the appropriation of the Materials to Chimney-Pieces. Upon the before mentioned diftindions we fhall be able to fpeak intel- ligibly to the ftudent with riffpect to the difi^erent kinds of marble, and their proper ufe. When we can be diflindtly underllood what is the cha- racter ot the fimple and continued Chimney-piece, that with mere fculp- ture, that with columns, and that with figures, we can without te- G g dioufnefs ir4 c H r dioufnefs explain, what is the kind of marble fulted in general to either purpofe. Having given this diftindtion of Chimney-pieces, that of marhle fol- lows, the nature of the materials being a proper appendage to the va- riety of the works. We fliall confider the (everal fpecies particularly hereafter ; but for tl^e prefent it will be necefiary to eflablifh only one ge- neral diftindion, this is, into the plain and variegated marbles. By the plain the ftudent is to underftand thofe marbles which are throughout of one colour, whatfoever that be ; and by the variegated, fuch as have more than one colour, however, difpofed. Of this latter kind there are a great number, and they have their variegations in different manners and degrees, but in whatever degree or form they are diflributed, our rules to be eftablifhed in this place fuit them alike. Many of the variegated marbles are very expenfive in the firft: purchale, and fome of them have a vaft additional charge attending the cutting. 7hofe to whom expence is a recommendalion (and there are too m my of that clafsj determine generally by this, and allot the moft expenfive kinds for the richeft Chimnies : but let our ftudent guide himfelf by better rules ; let him confider to what purpofe each will beft ferve, which have the moft compact fubftance, and will beft anfwer to the artift's chillel, and which from their fhattery nature are ntteft to be wrought plain. This is a rational and great diftinftion j the architedl that goes to work without this confideration, and without a knowledge of the nature of the feveral kinds, will involve his proprietor in expence to no purpofe, and luirt his own reputation. This is a diftincftion founded on the nature of the materials, and is therefore to be obferved inviolably ; but there is alio another of almoft equal importance, though much lefs regarded, which refults from their plain or mixed colouring. The ancients were aware of the effedls of this upon the eye, and they conducted themfelves in general accordingly. There are exceptions ; for there were unavoid- able neceflities in fome cafes, and there were among them Ibme workmen of lefs judgment; but in general the rule by which they guided them- felves was this; when they intended a great deal of ornament, they em- ployed a plain marble ; and where they prcpofed lefs workmanfliip, they allowed the moft variegated kinds. The reaibn of this is evident, and it is furprizing that all ages have not attended to it : the beauty of iculpture de- pends upon light and fliade, and therefore every thing which difturbs the light in this refpeft, defeats the purpofe of the artift. Any thing creates this difturbance, that occafions a different refiedion of the rays of light; and we know that the rays differ from every colour. Tne Ihades give the eye all the idea it has of this great ornament ; and thefe are diverfificd when the light is refledted from an objedt in different colours. Therefore C H I 1^5 Therefore for all fculpture and ornament, the bed material is that which is of one fimple celour. This is an invariable rule, fo inded upon unalterable principles in the nature of things ; and this the voung ar- chitedl is to make the firil: guide of his conduft. This will throw him upon a determination very different from that we have named as the com- mon opinion of common judges; inftead of bellowing the richeft-co- loured marbles upon thofc Chimney-pieces where he intends the greated expence of ornament, he will referve thefc painted kinds for fuch as he intends fliould be wrought with lefs ailiftance of the chiflel ; and he will adopt for thefe high fculptured pieces always a plain marble of one un- interrupted colour. Of a Doric Chimney-Piece. Upon the plan already laid down, let us now advance to a Chimney in which there is the ufe of an order. We begin with that which flands loweft in rank among thofe proper to be ufed for this purpofe, the Doric ; and there is none that anfwers the intent more happily for general occa- fions. If ever the Tufcan order {liould be thought of, the common room of a Dutch ordinary would be the only place for it, and then wrought in wood, it might ftand an emblem of the tafte of the country ; hut the very next ftep to this raifes us to great elegance and dignity. As the Doric is an order very well becoming a Chimney, it will natu- rally be moft ufed. No richer order need ever be thought of for a par- lour ; and there are very Izw dining or drawing-rooms in which it would net be proper. We will propofe fuch a Chimney in its plain ufe with- out addition or continuation, that the ftudent may not be embarraifed with any additional articles in the confideration ; and we will fuppofe ic in a parlour papered in the prefent falliionable manner, where nothing is added to it, and where, from the plainnefs of the reit, and the great dif- ference in colour it (lands very confpicuousj the fird object that ftrikes the eye on entrance, and the only one that can fix the attention. In this cafe, as it will be confidered flri(flly, let the architedl take care it be liable to no objedlion ; and as there will be lome expence in the ufe of the order, at any rate let him take care the afpefl; be great care in chufing a perfedf and well figured-piece; and in giving it the mod complete pclilh of which it is capable. There are ibme of the old marbles much more fit for the purpoie ; the true verde antique, will be a glorious addition in this place, its elegant green being altogether unlike the whole ; and upon this the ornament well wrought in the fame ftatuary kind will be very elegant. A tablet of the true por- phyry will alfo fuit very happily ; its bloody tinge never fhewing itfelf fo rich,' as in the contrail of the pure white of this llatuary kind If thefe do not p'eafe, the choice lliould fall upon the granite, whofe fingular afped, thus contralled with the reft, cannot fail to pleale every eye j and whofe everlafting polifli adds greatly to its recommendation. Having thus eftabliOied rules for conftrudting thele plainer Chimney- pieces, we fliall, in our next, enter upon luch as receive the addition of figures. Of a Chimney-Piece ivii^ Figures. We named the ufe of Figures, that is, the introdu<5llon of the Perfian andCoriatic orders in the decoration of Chimnty-pieces ; and as nothing that can be ufed on this occafion is more delicate, we fliall, by a familiar inftance, explain the general doftiine relating to their uie. It is enough to fay here, that they are reprefen rations of perlons ot different nations, whom, inftead of devoting for life to the meaneft and moll laborious employments, the Greeks configned to immortality in the figures ot them in their temples ; fupporting the weight of the upptr part of the build- ing, or leeming to fupport it. Men ot rude genius reprefent them cruflied and finking under the weight, and think it a high degree of merit, if they can figure in their fcuipture, ilarting eyes or burfting finews. The Greeks detelUd fucli barbarity ; nor, I hope, are we fo juftly cenfured for a love of c uelty, that fuch fights could pleafe us. it was enough for the polite and hu- mane CHI 121 mane Greeks, that they could place them for eternity in the condiiion of abjedl flavery ; they did not defire to make the load oppreflive. Their figures were eafy, and the incumbent weight was not great. Let us in all things imitate them j but it is in no part of architefture we ought fo ftridtly, or can fo eafily follow them, as in the ufe of thefe orders in the decoration of Chimney-pieces. The eye is continually upon thefe figures when placed in fuch a fituation j and he muft have a barbarous fancy, who would wifh to difpofe them in attitudes of horror. Every thing there fhould have an air of chearf ulnefs ; at leaft, nothing fliould give the idea of conftr^int or pain. This general maxim will guide the {Indent in his choice and difpofition of thefe figures; and he will naturally acknowledge the force of two ge- neral rules for the choice and difpofition of thefe figures. 1. That the Perfian order is fittefV for the continued Chimney-piece, and the Cariatic for the fimple. 2. That very little weight be laid upon either ; that the fimple Chim- ney-piece of this conllrudlion terminate abfoluteiy at its proper mantle- piece, which muft be the top of the entablature of an order j and that in the continued kind, the ornaments to the ceiling be light ; and the materials alfo of a light kind : upon this alone depends the idea of eafe in the figures ; and confequently upon it depends entirely our fatisfadtion in viewing them. 7 his makes it natural that the figures fhould not be diftorted : and we fhall give one general diredlion to thefculptor, with refpedl to their coun- tenances ; which is, that the Perfian, or man-figure, have a look of in- dignation or contempt : and the Cariatic, or woman of dejedion without pain. Let the Perfian feem to fay he does not feel the load, but the in- dignity; and the Cariatic that fhe underftands her condition with hu- mility. Of a Chimney isoith the Cariatic Order. Let the perfon who propofes a Chimney of this kind, or who receives the propofal from his proprietor, firft reprefent to him the expence, I his *is a very needful article at firft fettmg out, for if it be omitted, he muit cxpedl, either that the owner will be flartled at the charge, or that the work will difgrace him. The figures in fuch a Chimney are near the eye, fo that every defedt will be feen as well as every beauty ; and thty are of the nature of thofe other elegancies in the art which had much better be omitted entirely, than done in a flight manner. It is ufual to croud other ornaments among them, and about the fame Chimney; for the common opinion is, that one fine thing muft be near another ; but this we do not mean. Plain- 1 i ncfs 132 C H I nefs in a certain degree is preferable, becaufe it is more correfpondent to the fi:^iires ; but the needful expence is, that the Chimney- piece be of fufficient extent and hignefs, that the m.iterials be good, and that a full price be allowed the fculptor. He muft finifli his work according to the price ; and there is none too great that is within the bounds of reafon j for there is no occafioii on which his art may be difplayed fo perfedlly. We are to treat here of a Chimney of the Cariatic order, and accord- ing to our firfl: principle this muft be a fimple one. The female figures of this order are to (land at feemmg eafe, aud it would be monftrous to load them with ornaments up to the ceiling. Theiiifelves are lufficiently ornamental for the work, and the lefs the eye is difturbed in contemplat- ing them the better. For all thefe reafons, a plain or fimple Chimney, which tertiiinates at the mantle- piece, is the proper one for the receptioa of ihe Cariatic order. This mantle-piece fhould be formed by the pro- jection of the entablature, fupported by thefe figures, with no farther ad- dition; and there is to the true architeft an ablolute rule what this enta- blature fhould be. This deferves a ftridt attention ; for whenever there is an abfolute rule from antiquity, and no objedlion lies againrt: it in na- ture or reafon, nor any thing better can be put in the place of what it direds it is wrong not to make it abfolute, and accufe ail of error who depart from it. When we fpeak of thefe male and female figures, under the name of Perfian and Cariatic orders, we do not confider them as fimple ftatues, but as parts of an order of architedlure. They fupply the place of the lliaft of a column ; and they are tofupport an entablature. We fee fancied mouldings placed upon the heads of thefe figures in mo- dern works 3 for there is no error or abfurdity fo grofs, but fome of thofe whom of late times we have called architects, have fallen into it: but ia the earlier times it was otherwife : the chaile talle of the Greeks admitted none of thefe irregularities; the termination over a Perfian or Cariatic fta- tue was always the regular entablature of one of the orders. It was this which determined the order; for the ftatue ferved as the fliaft to any : and their general diftindion was, that the heavy entabla- tures fliould be laid upon the Perfian, as male figures, and the lighter up- on the Cariatic, or female. But this was not all, they appropriated one entablature to this figure, and in their corredl pieces ufed that only, it was the Ionic : none ferves better than this in the natural form and cor- relpondence to the figure, for a heavier would be ablurd, and the two fuperior orders have entablatures too much enriched for the ftatue. The Ionic entablature was upon this confideration more fuitcd than any other to the Cariatic figures, and this would have its ule general among that judicious people ; but there was a farther thought that made it uni- verfal : this was the commemoration of the great event they ferved to record C H I ^ 123 record, in all Its particulars. The lonians were the people who reduced C.iria to the Gretian yoke, they therefore placed the entablature belong- ing to the order of that name, always upon the heads of Cariatic ftatues, to tell this ftory to pofterity ; the I mians fubdued tnefe people. This, though hitherto unregarded by architedls, we (hall not hefitate to lay down as a law of the fcien.e ; that the Ionic entablature be laid upon the Ca- riatic figures in all places where they fhall be ufed. -■ eafon (hews it is proper, and the authority of Greece lu^iports it. The whole tnatter in thefe fanciful pieces is trifling, in compirifon of the regular majefty which is feen in the great original orders ; but when we ufe them, let us with regularity copy thofe who firft introduced them into thefcience; and like them tell the whole ftory. 0/ the ConJirii6lkn of the Figures. It has already been obferved, that the Chimney-piece in which thefe Figures are introduced fliould be lirgej that it fhould have no ornament above its mantle piece ; and that the mantle-piece ihould be the top of an entablature, and nothing more : it is determined that this entablature /hould be Ionic; and we are now to confider the conftruilion of the Figures. Their length being determined by the defign of the general work of which we fliall fpeak hereafter; the proportions are all regulated by that: the human form is the ftandard of tiuth in this refpedf, only let the fculptor remember, that it is a female Figure, and that it will be befl if he make it of the moft delicate form. No gieat weig t is to be fup- ported ; and confequently, no robuft limbs are necelTary for the purpofe. Thus much determined, two points more occur : the difpofition^f the limbs and the drapery. Thefe we (ha 1 confider ieparately. When Figures are raifed to a height which places them out of tiie way of accidents, their limbs may be difpofed with a freedom which cannot be admitted, where they are in the reach of blows : nothing can be more in the way of thefe than a Figure which makes part of the ornament of a Chimney, becaufe the perfons who fit near the fire, will lean or rub againft it; 'and the continual bufinefs of (ervants in managing the fewel will carry them alfo for ever in the way of touching it. Let the architect confider what parts are moft liable to damage. Thefe are the hands and feet ; and particularly the extremities of them, the fingers and toes. If the hands were dilpiayed at a diftance from the body ; and efpecially if the fingers ftocd loofe and free, a few days could not fill to m.im them.^ We fee this in effecj:, where injudicious defigners have formed them in that manner i and experience joins with realon in direding a con- trary courfe. The 124 CHI The fiifl: thought would be to throw both arms clofe to the body; but that would be at once ungraceful and improper. It is natural that a perfon loaded upon the head, although but flightly, fliould raife one hand to help to fupport the weight; and this mull: be done in the prefent in- flance. It will be higher than the part of the image that is in moft dan- ger of accidents. The arm, even in a delicate Figure, may be flrong enough to refifl: a little injury ; and the tender part of the hand may be defended from it. The proper poflure of a Cariatic Figure at a Chimney, is, to have one hand clofe to the body ; and the other raifed toaffift in the imagined lup- port of the mantle-piece. The hands mufl be delicate, to correfpond with the general Figure, and they will require the bell touches of the fculptor's thiffel, becaufe every eye will naturally be thrown upon them. The fingers muft be Imall to anfvver to this general defign ; and thofe of the lower hand will be expofed naturally to blows and injuries; while thole of the upper will not be altogether exem.pt. The delign of the ar- chited IS to fliew his judgment in fecurmg them gracefully ; as the fculp- tor does in forming them. The hand that is carried up to fu jport the entablature, may very properly be placed upon the freeze ; and in this cafe, the projedlion cf the cornice will give it a great fecurity. It would be very proper to give the order its pulvinated or roundifh freeze (or this purpoie, that the hand may be Oiewn in all its delicacy, gralping it. In this cafe, the cornice would not only be its defence ; for the fingers might be united to the body of the freeze, and thus would have a ftrength that they never can when loufe. This hand being fo fecurely difpofed, let the Audent confider what can be done to preferve the other; it is in moft dancer becaufe it hangs loweft, but there is an eafy way to defend it. Nothing can be fo natural an employment for this hand, as holding up a part of the robe; and this may be its fecurity. There will naturally be a told and a rifing in the part held up, and thefe may be wrought though with the utmolt delicacy, yet with great fubftance. In the hollow un- der the rifing may be placed the hand, in which the moft delicate touches of the chifibl may be fhewn, while it is thus preferved in the greateft fecurity. Should any one fuppofe the neceflary lightnefs of the robe cannot be preferved with this quantity of fubftance, necefllary to prelerve the hand from accidents, we refer them to the Flora, well known to all who have viewed with tafte the rarities of modern Italy. The quantity of marble in that is three times what is beflowed on moft other b igures, yet it is the lighteft of them all. Of CHI 125 Of the Drapery. Modern fculptors delight in nudities; but in a Chimney-piece they would be abominable ; they would (hock the delicacy of our fex, and could not be feen by the modeft of the other ; they are therefore abfo- lutcly excluded from this fervice, and feme Drapery is always to be al- lowed : the queftion is, how much and in what manner. Let no ilatuary obj dt that the great excellence of his art is withheld, for that it would confifl: of mufcular figures. We banifh anatomy from the parlour of liie polite gentleman : that is ail. Let him copy his gi- ants for expofure, from thole mafculine forms the ancients have left, or from rough and violent nature; but here let him give his figure cloath- ing. Nor (hall we (ufFer the complaint unanl'wered : we (hall tell him, it is as difficult to excel in Drapery, as in nakcdnefs ; and may refer him to thofe cloathed ftatues of the Greeks and Romans, which it would be glorious to imitate. That thele are capable of equal excellence, and may obtain the fculptor equal praife is evident from thofe examples: with re- fpedt to the elegance and propriety, all may judge. Of the ConflruSlion of this Chimney. Much is now done towards the general conftrudlion of the Chimney- piece ; for in confidering the feveral parts, we have obferved, that there are to be two female figures fupporting an entablature, whofe top lerves as the flat of a mantle- piece. We have eftabliflied it as a nece(rity, that the whole work be of confiderable extent; and there remains only tu place the figures, and add an inward ornament to compleat the Ifrufture. Let the figures be placed near the extreme edge, but not abfolutcly upon it, for they will be the better (hewn when a part of the fiat-woik projtdls beyond them; and they will alio be more fecure. Let a kind of plinth be placed under them, for it is by no means pro- per they (hould reft immediately upon the hearth ; and this will lerve the fame ufeful purpofe in preferving the toes from injuries, that the freeze of the entablatuie anfwered for the defence of the hands. They may be difpofed both firm'y upon it, and be made of one piece with it ; or that foot which projedts forwardeft, and is there in moll danger of hu't may be fo difpofed, and the other which is backward may be made with more freedom, to reft lightly upon it by the toes, or if the iculptor pleaks to be abl'olutely removed from it, it will be fafe from its pofition ; and he may employ all his delicacy in conQrudling it with fecurity. As the foot rcfts upon a plinth, the head is covered by the entablature. It mull hs brought forward to anfwer the projection of the figure : and this wiij K k give 126 CHI give a relief of light and fhade to the whole, and be an ornament to the conftruftion. There being a fmall fpace of the back beyond the figure on each fide ; there muft be a larger within, and this will require decoration; every ar- ch itedl knows this, and the fault is ufually that of employing too much. The opening of the Chimney will be much Icwer than the mantle- piece ; or, properly fpeaking, there will be a confider.^ble fpace between the ornaments of that aperture and the lower member of the entabla- ture : this mufl: be allowed lome ornament, but let it not be too much. A vafe will be very proper in the middle ; and a feftoon on each fide to the edge. The ornaments which furround this aperture mud be hand- fome mouldings. They muft not be continued to the level of the heai ih, but terminate at bottom on a plinth of the lame form with that which fupports the ftatues. Thefe may be ornamented with fculpture; but it is an expencc better faved. There is a correlpondcncy of parts which is preferable to decorations of fancy ; and this is only to be found in fuck a ccnftrudtion in plainnefs. Of the Materials cf this C H \ M nn y. Let it be obferved, that the figures be of pure marbl'", of one limple colour; and none is fo proper as the plain white, which wc know by the name of the ftatuary marble. If the whole ftrudture be of the lame, none can objeit to it; but there will be tiegance in giving the back and body of the work in marble of another colour. Great beauty will be difplayed in making the body of the Chimney of the green and white marble, which is commonly called Egyptic^n j but the greatefl: elegance of all would be to work it in porphyry. The com- mon purple marble would not aniwer the purpofe, becaufe the fpots and cloudings would confufe the eye; and as it is not eafy to find a perfon of fuch expenlive tafte as to go to the price of porphyry, we (hail p opok to make the back of Syenna marble : this is of a colour which very finely {hews white, and will elegantly anfwer the purpole ; and finely orna- ment the figures. Of a Chimney-piece, ijchofe fok Ornament is Sculpture. Let us on this occafion fuppofe a room of a moderate fize, fini(hed in the fafhiontble way, with light ornaments on the cieling, and wit'j ihe walls papered; a Chimney-piece of fome elegance is to be eicdted in :iiis room; the propiietor diilikes the orders; or the natural bignels of the whole is not fufficient properly to receive them: the architedl is to ^ive him a defign for its conftrudtion ; and he begins with a general outline for C H I 127 for the fides, and a more particular confideratlon for the top. This is to be the feat of ornament, and he adapts to it the decorations of an enta- blature of one of the fuperior orders. In his firft defign he fees a flat- nefs that difplea(es ; and, to remedy this, feme parts mufl be brought forward. We have obferved how rnuch beauty the projedion of the corners of the Ionic entablatutc over the heads of the Cariatic figures gave to that Chimney ; and the fame elegant diverfity of light and fhadovs^ will occur from br nging forward the two ends here. If this be not enough, place a pediment upon the centre. We fliould have objedted to this in the pre- ceding inltance, beeaufe it would have loaded the figures j but here there k no obje(ftion. A tabltt fhould be placed in the freeze, under this pediment; and the prcjeiting part at each corner will admit in its freeze a vafe. There re- quires a face, or fome other principal figure in the tablet; and thus is laid down the principal of decoration. Th':!re fwelling corners of the entablature require fome fupport ; and as columns which would naturally occur for that lervice are forbidden, the mofl: proper delign is a fcroll on each fide, in the manner of a confole. This will admit a kind ot flu- ting or cabling at diftances upon its furface ; and an acanthus leaf may co- ver its lower part. There will be beauty in fuch a conflrucftion ; but the judicious eye will only allow thefe as an apology for columns. The fcrolls mufi: not reft upon the hearth, but on a plinth ; and the 'addition of this compleats the material part of the ftrudture. What re- mains is bculpture ; and the nature and defign of this is plainly pointed out. The common carving of a quarter round into what are called eggs • and anchors will ferve to decorate the inner edge to the aperture; and ■ the proper Sculpture of the mouldings for a cornice of a rich order gives nearly all the reft. A fefloon from the face to each edge of the tablet, and another on each fpacc on the two (ides of that projed;ure, finilli the whole; and there appears a Chimney fomewhat lels expenfive than it would have been if the orders were employed. But though it muft be allowed a great deal of beauty in this way, he mufl have a poor conception of the grace and dignity of thofe great parts in architecture, who does not lee the addition in beuuty from the ufe of them, would have been much - greater than the extraordinary expence. The materials of fuch a Chimney are limited by the quantity of Sculp- ture. To fome marble of one colour ; for the greater pirt of the expence would be thrown away upon a veined or clouded marble, btatuary-mjr- ble is again peterable xo all othvio on thi:. occfion ; I ut the who e in a pcrtedt blacK. would have a very agreeable, -hougii gr;4ve aipedl. If a gayer marble be ufed, the b^cnni. ib befl ; but m ihat caie the felloons, . and other oinamt-nts, will be btll in Itatuar^^. A C H I M- - ■|2g CHI A Chimney-piece tvith fngle Doric Columns. The room in which the Chimnev-piece is to be placed, may be fuited to a lighter, or to a more mifiy kind; for this part ot the finidiing fliould always be correlpondtnt to the reft; and this may give a rule for varying the pradice. We will fuppofe, for the prefent inftance, a room finifhed in a modern degree of elegance, and that the proprietor delires to have a Chimney de- corated with one of llie orders, but not at too great expence. In this cafe, the finilTiin^s of the room, and the intention of the owner in point of expence, limit the number of columns. The fiill: thought refers he architedl to the Doric order, as by far the leal! expenfive ; and both deter- mine againft more than one column on each lide. Upon this plan i' will be eafy to conllrucl a light and elegant piece; the price of which ftiali be very mode; ate for a Chimney with an oidcr, and its lightnels corref- pondcnt to the rell or the work. Let the Undent mark hrft upon his paper the outline of the aperture. Then on each fide let him mark the outline of the work; to which, as there is to be only a fingle column, he needs not allow great breadth ; and after this let him draw the outline of the top member of a Doric cornice, determining its height from the meafure of the Columns. We do not intend to determine the work here : bat let this be firft done. Let an open pediment be raifed from the middle of the cornice ; and that this may not ftand naked, let another ftrait line be drawn iuil above its top, and flopped each way at the breadth of the fides. The cornice of this order will project farther; but that is not to be the meafure of this upper work, which is to ferve as a continued attic for the finilliing. Of the fever al Parts in this C H i M N e v. The outlines thus laid in, the fludent will eafily comprehend the dif- pofition and form of the feveral parts. Let the columns be firft confi- dered, and let them projedl )o far as to ftand bfolutely free and clear. Let them reft upon the hearth by their phnth : on this place an attic bafe ; and carry up the fhaft, with its regular diminution, according to the rules of Palladio. On this place the capital, and let its ahacu^ lange with the line which marks the top of the apertuie. Upon this capital let the regular cornice of the order reft. It muft projedl to c me over the column ; p.nr", receding ejch way to the back of the Chimney, there will be an agreeable mixture of light and fhade. Let tlie whole aperture of the Chimney be terminated by an architrave, with a carved quarter- round lor the inner edge, and over the center of the Chimney's opening let CHI 129 let it rife to fuppcrt the cornice. The pediment is placed above this, and this rifing or the architrave has the appearance of a reg lar liipport to it. The fret-ze, where it is continued entire, m\il\ hive its proper ornament of triglyphs. One will (land over the axis of each column, and two on each tide, between the projedure for the column, and the riling of the architrave. In this Chimney, whofe expence is to be of a limited kind, we would have ihe netop:s plain, cr left withcut ornament; and confequently the neck of the column muft alfo be plain The rofes in molt cales allowed to this part cofl little, and are a great ornament ; but they muft not be ufed when the metopes are plain. Over each of the columns let there be raifed an attic pilaiter, projeding as the column does ; this con- fining of its bafe, die, and cap, will give the ornament of the plain courfe behin i : its bafe muft be continued each way to the peaiment, but there interrupted by it, and the cap muft be continued along the whole courfe over the top of the pediment. Of the Materials for this Chimney. The fculpture being little in this piece^ the architefl has his choice of materials. There is fo much decoration of a nobler kind, that the plaineft will ferve; at the fame time the fculpture is fo little, that the moft pompcus of the variegated kind may be ufed. The body of the work may be of flatuary, and the columns of Syenna marble. This will be a very happy mixture, for the gold and purple of that elegant fpecies are rn-ver fecn to fo much advantage as when contrafted with white. The body of the work of the common purple and white, and the columns of the ftatuaiy, would alio be handicme ; or if the columns were of the French onyx marble, and the back white, the colours would be fhewn in the luoll advantageous manner, and the columns would appear like agate. We have a green and fpotted marble in Anglelea, that would make very handfome columns for a white ground, or a very handfome ground tor w hite columns ; and there is a fingularity in this marble which fhuuld make it extremely valued : this is the veins of aibellus, which are lodged in it. Thefe are of a glolTy white, with a tinge of green ; the veins are bbout a quarter of an inch broad, and the threads run crofTways. They are !o extremely dole arranged, that they look as firm as the body of the marble, and not even fire can hu t them. This greatly exceeds the ccmmo;i green and white, whicli is called iEgyptiati marble, and ought to be more regarded, LI Of 130 CHI (J a Chimney with Termini. We have given the ufe of columns in pliin Chimney-pieces, and the appropriation of Icrolls to liipply their place, where any particular fr.ncy in the proprietor declares agaiuft their ufe. It reniAins that we treat of a kind between the fanciful or Cariatic orders, andthele fcrollsj and thefe ;irc of the nature of Termiin. Theyconlift of the head and breafl: of a human form, and a fcabbard receiving the limbs. We fet out with obferving, that fancy was to be freely indulged in the conftrudlion of Chimney-pieces : thefe are, or all the figures that can be introduced, the moft fantaflical ; and it will be no where fo proper to introduce them. When the ftudent falls upon a defiga of ufing them, let him firrt obferve, that one of the fimple Chimncy-p'eces, that is, one of thufe which terminate at the mantle piece, is fittefl for the recep- tion of them ; for it would not be cafy to continue a correfpondent orna- ment to the top of the room. Bcfides, as in fuch a Chimney there muft naturally be a great deal of fculpture, the continuing that in the fame talle, if a proper form could be devifed, would be of enormous expence and would diftrad: the eye. It is fit the attention fliould be fixed where ther. has been fo large an ex- pence, and fo much labour and geniu'' to demand it ^ and for this reafon, as well as the other, the work fliould be confined to one place, beftowed about the lower part of the chimney-piece, and full in the eye on every occafion. Of the Confiru£iion of this Chimney-piece. The firfl confideration of the architeft in a defign of this nature, muft be that of giving it a freedom in all its parts. There will be fomtwhat maffy in the figures themfelves, for it is the nature of thefe kind of de- figns to fwell out at the breaft ; but he is to contraft this with lightnefs, and an airy look in ail other parts, and to give free fcope to his imagina- tion. On thefe principles let hnn fit down to his defign, and mark with a faint line the outline of the whole. This will be naturally three fides of a fquarej but it is to be broken through on feveral occafions j for fo many Itrait lines would give a llifFnefs altogether dilcordant from the de- fign of eafc and freedom. This outline firft given, which only ferves to determine the general extent, let him defign his termini. They are to be raifed upon a fquare plinth, and their heads are to lupport the mantle- piece. This gives their height, and from ti.ence are to be deduced their proportions. As thefe are the principal part of the Chimney-piece, let them be drawn firft, and the reft made correfpondent to them. The face. CHI 131 face, the neck, and a part of the breafl:, is all that mufl: appear human ; and as this part of the bv)dy is much more graceful in the female form, let them reprefent women. Let the head be decorated with flowers among the hair; the neck be naked, to fliew its true proportion ; and let a feftoon of flnwer^ fall carelelsly over the breaft, to hide the reparation in the midft, and reprefent the fullnefs, and beautiful round, without coarfenefs or indecency. The fculptors of this time require nothing fo much as to be taught with decency. The necks of females, from their hands, are generally improper. We may refer them, for better information, to the prefent drefs of the French, who fl)ew all the beauty of the female breaft, yet by a rofe, or fome other artificial flower, in the middle, take off every idea of immodefty. The human part of the figure thus finifhed, the fcabbard corries into confideration. This receives the breaft, and has a fpiral line on each fide at its top, where the arms feem to have been taken off. There is no pa-t of the fcabbard lefs beautiful than this, though cuftom, and the pradlice of the antienf, has rendered it eflential. The feftoon we diredl to be thrown lightly over the breaft, may be continued with eafe, fo as to hide a part of this. From this part the fcabbard will confift of a front and two fides; audit muft be covered with fculpture. A great deal of work fhould not be employed on this, becaufe it is not the principal part of the defign ; but they err who give it too little. The ridges fhould be plain but carefully wrought in that plainnefs; and, for the ornament, it may be only a Mofaic, by light lines crofling one an- other, or this may be more ornamented: or, finally, the defign may be varied. This Mofaic, when it confifls only of lines, is very plain, and in fuch a Chimney as is here propofed, would be unworthy of the reft. The lightef: ornament is by adding a kind of ftar at every interfeilion of the lines ; and the moft that ftiould ever be allowed, is by placing almall flowerin the center of each lozenge of the Mofaic divifion. When thefe flowers are added, there fhould be no ftars in the interfedions ot the lines ; and when there are no flowers or other ornament- within, this fhould never be omitted. Thus is the general decoration of the fcabbard to be determined ; but there yet remains to be confldered that fuperior article of ornament, the varying the defign upon this part. The leait that is to be done in this way, is to place a rofe in afmall compartment in the middle of the fcabbard ; and this, when the Mofaic is continued, will give an air of variety. The other and more graceful method is, by dropping a leaf from the top down halfway of the fcabbard. This fliould be an acanthus leaf, becaufe its ihape correfponds, and no other is fo handfome. The Mofaic divifion will then perfedlly well anfwer for the other half, and may be carried up all the way on each fide. It will be a farther grace to this fcabbard. 3 = C H I fcjhb.irc!, to let the foot of it rife from the plinth with a fwelling within ; and this may be very happily dtcoraied alio with a leaf. 7 hcle figures linis finifiieii, the reft is eafy. A mantle-piece is to reft upon their heads, where it muft projedl with a rounded outline; and both here and in the ifrait part it may be decorated with Iculpture. The inner line of t' e Chimney-piece may be a rounded and handfome moulding, wiiieh at the top may be carried, according to the French niann r, mto an irregular arch. In the center of this a fcroll may fupply the place of a kty-ftonej and this fpreading each way from that central part, may leave room for a bafket of fruit, and terminate each way in a kftoon: and then the rife of the mantle- piece being decorated with leaves and fanciful ornaments, the whole will be correlpondent, and of a piece. Of the Materials for this Chimney-Piece. The rule we have laid down of allowing coloured marbles where there is little fculpture, and plain ones where there is more, holds veryftrongly here. We recommend this Chimney-piece to be conitruited entirely of pure ftatuary marble, as that will moft diftii (ftly flaew the work ; and the eye, having no glare of colours to take it off, will be wholly kept upon that. However, as lome think there i*; a dcadnefs in this ftr.dl unifor- mity, we Ihall adviie the ftudent in what manner to give a decent variation. The body of the Chimney -piece being ^i white marble, the Icabbards of the termini may be of the gretn Anglefea kind, or of the common green and white Egyptian ; and in this cafe it will be well to make the mouldings round the edge, of the lame materials with the fcabbard. The flower-bafket may alfo be of the green marble; but the fruit and flowers in it ftiould be white, for all the delicacy of the work will other- wife be loft in the veins and cloudings. Of continued Chimney-pieces. The ftudent is now fo far a mafter of the rules upon which the ftruc- ture and decorations of Chimney-pieces aie to be founded, that we may lead him with familiarity to the compolition of thoic of a more compli- cated kind. 1 hefe are fuch as we exprefled before under the n.ime of continued Chimney-pieces; and they require a more diftindl conlideration than, by the pradice of modern architeds, they Icem to be aware. It is no more than truth to determine from their condudl, that they have no other idea of this kind of Chimney-piece, than that it means a limple one, with lometliing at the top of it. Seme flutter of ornament, and f me fhape of a frame, they luppofe are needful on this oecafion ; but farther they feem not to have carried their rtfcarches. One kind of ornament, C H I 133 ornament, or one fort of frair.e, they apprehend will do as well as nn- othe: ; I'.nd when thev have made, orotherwife pofieffed themfelves of half a dozen figures for this purpofe, they apply them at random, and fecm to think of them, as the fair'ous comedian did of his prolog^ie and epi- logue, that tiie eDiiogue might do for ?. prologoe, or the prologue fur an epilogue, and that cither of them would ferve any other play as well as that for which they were intended. We do rot oioduce thefe blemiflies in our heft buildings to ridicule, much Icfs CO injure thole -'^ho invented them ; and therefore conceal the names they wou-d difgrace. It is fof the fervice of our ftudent we repre- ftnt them in tluir proper colouis. Th^y are Co frequent in ^ood houies, and the; pais lb often witnour cenlure under the review of reputed judges, that, "weri- it not for fuch caution, he might be led to think them right; and pLice them before him as examples 'or his condmlit • at lead: as ex- cufes for his own errors. We have told him betore, that it is to very few of the flrudures of this ige he is to loolc up for example ; and wc fhall repeat the decifion before made on a like occafion ; that an error is not the lefs fo, though juftified by a thou and inftances. Of this he may be /ure, that the very eyes which overlook defefts, will never be blind to beauties, and that he will enfure to hinileU, not only a greater, but aa univerlal praife. by ad;ing up to the rules of truth and propriety. Longinus dirtdis tnc orator, in order to arrive at excellence, to fup- pofe the famous p cdectfTors in the art are prelent; and upon all occa« fions to put himielf in their place for the compofition. Let the aichi- tedl, who would air.veat excellence in his not lefs arduous or lefs honour- able fcience, tread the fame path. When he is about to lay down the delign, let him confider well the occalion, and afk himfelf : what would Palladio have done in fuch a circumftance ? When he has finilhed, let him demand, what would Vitruvius fay were he prefent to examine this ? It is by this method men who have ai rived at excellence in any of the polite arts, have imbibed, as it were, the genius of their great predecef- Ibrs. He muft have mdeed a cold imagination, who could defign mean- ly or incorredlly when he fuppofed himfelf adling in the fpirit of that reverend modern, or appealing to the judgment ot that judicious antient. Of the Piopriity in the Ornaments. The 6rfl: confideration which would rife in the mind thus warmed with the remembrance of thole pcrfons immortalized by the fame fcience, would be propriety. Without this, beauty would be ridiculous; for, from the con^iuil of thofe whom, though unnamed, we have been ob- liged to ioa'1 with fo much unwilling cenlure, he wjU firft confrJer by what means the whole will be mod naturally fuited to the room in w hich Mm it 134 C H I it is to '^c plnced; and next, in what manner the two parts (for they are in ihemfJves didii d:, though joined) will be heft adapted to one another. With regard to the firft article, we have in generil oblerved already, that a rontinucd Chimney-pitce can only be proper where there are Ornaments of fculptnre about the room : for othervvife there will be nothing with which it can correfpond : therefore, againO: all other confiderations, let ])im delign at all times a fimple Chimney piece for a room that is hung, and a continued one for a room ihat is finiihed any other way. No wain- Icot is or can be mjde without pannelsj and it will be eafy to make the upper part of a continued Chimney-piece cctrefpond with them, le; them be of whatfoever kind. This we would recommend to the attention of the builder, even in the plaine[I and meaneft rooms. There will be a re- gularity in it which will never fail to pleafe, and the expence nothing. In this tale no more will be required than to form a regular defign of an upper part for the Chimney-piece intended to be placed there, and to exe- cute it with the common aiouldings of the pannels. There will be no more expence in difpoling them properly than improperly, regularly than irregularly ; and yet the tffcft will be pleafing, and the architect will have credit. He now underflands, that the purpofe of this work is to raife an Or- nament like that of the other p>irts cf the room from the Chimney-piece to the cielirg ; and in fuch manner to adapt this to the Chimney-piece itfelf, that it ihall feem naturally to rife from it, and to be connected with it ; that it fliall be a regular and proportioned part of the chimney- work, at the fame time that it is alfo a regular part of the Ornament of the room. This will always be eafy to the architedl who fets out upon juft principles ; for having, according to the rules we have laid down in the preceding book, fuited the Chimney-piece itfelt to the reft of the rcom J thele additional mouldings, or other Ornaments, when they are m;;de to correfpond with one of the two, will alfo agree with both, be- caufe they naturally agree with one another. It would be otherwife with one who had fet out without principles. If he had mide a fimple Chimney-piece too rich or too plain for the reft of the room, then the upper work, which continued it to the cieling, would add to the irregularity : for either it muft be made to agree with the lower past of the Chimney, and would fo difagree with the reft of the room ; or to corielpond with the finifhings of the fides, and by that means difagree with the lower part of the Chimney. Thefe are the ac- cumulated irregularities which never fail to arife from an error in prin- ciple. Let them teach the young architedl circumfpeftion, and early re- gular method. Of CHI 13s 0/ enriching a continued C h i m n e y. As the ftudent will now underftand, that the upper part of the conti- rued Chimney-piece, that is, all which is above the place of the mantle- piece, is a kind of repetition of the work, in the hdcs of the room hs will know very well in what manner to add p'oper beauties. Let him confider it is the firfh objedl that ftrikes the eye on entrance, and the nioft confpicuous part of the room; and, for that reafon, whik he eivcs it the fame air with theieft, kt him mske it fomewhat richer. We have ob- ferved, that in the plained: rooms it is to be only a coatin,utian of the mouldings of the wainfcot in a proper form : from this the fir.'t advance to elegance is the adding of a few more mouldings j and after th .t all the reft is eafy. When the common mouldings of the wainfcot have foms fculpture, let thofe which are continued over the Chimney hive more, as well as be laid in greater number; and to whatever degree of elegance the reft is carried, let this part exceed it. The continua'jon thus ma- naged will have the air and afpedl of a peculiar piece, while it is at the fame time a regular and perfectly correfpondent part of the whole finifliing. Rooms which are hunc: are debarred bv the rules of the fcience from the advantage of this ornament; but for all other kinds it is very well adapted. Where the walls are plain ftucco, this upper part of the Chim- ney-piece muft have very little ornament : but even in that cafe, as the lower part will naturally be very plain, a light reprefentation ot its molt confpicuous parts in the fpace above will be tar from unplealing. This is a very rare cafe j but we would not have the ftudent without liis rule of conduct in any. Let him not fuppofc this circumftance of a roam hnilh- ed with plain ftucco, to be a parallel cafe with that of one hung with pa- per or damaik, and in which we limited him to the ufe of a fimple Chim- ney. Here the fpace within the pannel over the Chimney being plain as the reft of the wall, at the fame time it admits the grace of this addi- tion, keeps up a fimilarity with the reft', without any thing improper in itfelf ; but, in the other cafe, the great contrail in the colour and figures of the paper or filk would break in upon the intended compofure of the whole, and the mouldings, whether in wood or ftucco, wou'd appear to be ftuck on the paper, not to rife from it, as they will certainly appear to do from the (lucco wall. The upper part of the Chimney-piece, which in the cafe of our plain ftucco-wall thews itfelf only in what it is, that is, a light ornament continued from the lower work of the Chimney, will, where there is paper or filk, have the afpedt of a frame ; and thefe ■will appear as pidtures in it. All know how poor this muft look ; fince. 135 CHI in tlie reality, what could be I'o mean as the thought of framing a piece of the hanging ? IndeeJ, if in a hung room it is intended to place a piftnre over the Chiinney, the frairie of it (hould be feparate, and fhouTd not rife from the Chimnev -piece below : whereas in other inftances, where the continued Chiiniiey- piece is proper, nothing is fo elegant as to make its upper work ferve as a frame for fome elegant piece of painting. In tliis ju(i: examina- tion we fee, what might have appeared as an objtdlion to our general rule, ftrengthens and fupports it; and although in a plain ftucco-room a conti- nued Chimney-piece is proper, yet in one hung it is perfectly wrong. 0/ /uiting the Upper Work to the R o o m. It appears that in all rooms, except fuch as are hung, a continued Chimney-piece may be allowed. In moll it will be found more proper than a fimple one ; and in the more richly furnifhed apartments altogether necellary. We are about to confider the manner of accommodating the upper part of fuch a Chimney to the room : but we mufl here cenfure fo'ne modern works; and, without naming the workmen, caution our lludent againif their errors. There have been fome who have entertained a confufed fenfe of the neceffity of this great article, the conforming the Chimney-piece (when, from being carried to fuch a height, it becomes fo confpicuous a oart of the room) to the other ornaments. But the ju- dicious reader will allow, that we have uled a gentle term in calling thefe only confufed notions, when he fees in what manner they have brought them into execution. In a room where the doors are decorated with aa order, this idea of corierpond(.nce of parts has carried them to the pla- cing coupled cc^lumns upon the Chimney piece in the continued or upper part of the work ; refling upon a mantle-piece, which is fupported by a fcroll. It reminds one of the c'ecoration of thofe theatres, where a Ca- riatic is fupported by an Ionic column, and that refts upon a bracket. There is in this the double abiurdity if placing the columns without fup- poit, and of giving them ni. thing to carry. They appear monllrous, be- caufe they are u- finifhed : they are t( o bu'ky, and too prominent for the place ; and nothing can be more prcpoflerous than this ufe of them, So far may errcr, in attempting what (hould feem right, carry thofe whofe minds have not imbibed the true principles of the icicnce. A correl'pundence of parts is indeed the firfl principle of ornament ; but, before a man pretends to ufe this, he mu(t know what part!^ (hi.;uld correlpond, or the attempt will only ferve to betray him into ab.urdity. The ornaments of d ors, and thole of the Chimney, fhould certamly correfpcnd ; and we have before diredlcd in what manner. But there is a place for every ornament ; and, when it is out of that, it becomes a de- fe(ft CHI 137 fet although it be in re.dity diftind, it ihail fcem a continuation each way of ihe feftoon on the tablet. The remaining ornament of this Chimney-piece muft depend upon the fculpture of the mouldings ^ and in tliis the l3n)e care muft be taken, as in the preceding inftance, that this be varied in io carelul a manner, thut CHI 153 that the feveral parts tend to fet ofF one another, not to confufe the eye that is detained upon them. The great caution in this refpedl will be required at the cornice, for in that part the fculpture will be clofe. The two mouldings we have diredled to be given to the three pieces which conftitute the inner work or firft frame, muH: be cut into a bold and ftrong elegance of this kind; and as the reparation is confiderable, we fha'.l allow in this what we declared againfl in the other, that is, Tome ornament on the piece between. This mud be light, and confift of large parts, and by this means it will at once have an afpedl of diverfity, and will not confufe the light. Of a Chimney-Piece and Wind-Dial, We fhall clofe the article of Chimney-pieces with one of the continued kinds: in which, befide the Angularity, there is ufe. Everyone knows, that from a vane at the top of a houfe, turning according to the courfe of the wind, a dial may be made, with its hand, which anfwering di- redly to all the motions and changes above, fhall point to thofe diviiions on which are marked the feveral points of the compafs. This is familiar to every one on the outfidesof buildings, from that which is fo wrought at Buckingham-houfe, now the queen's palace ; but the moft ufeful me- thod is to place the dial within doors. Thofe who are to go out of the houfe to know the courfe of the wind, may look at the vane itfelf; but there is a great deal of convenience in bringing that indication into a room of the houfe. W.hen a thing of this kind is propofed, the firft bufmels of the defigner is to remember, that every room is not fit for it. A wind- dial in a dining-room would be an odd kind of ornament, and much more improper, would it be to place it in a more elegant apartment. The ftudy of a fea-officer, or other curious perfon, or the breakfafting- room of a fportfman, are the proper places. Of the Conjlriidlion of this Chimney-Piece. Continued Chimney-pieces are in a manner devoted to the fineft rooms in a houfe, and are therefore in great propriety covered with a profufion of ornament J but in this, which is particular in devi? 'ng from that rule, the firft principle is, to omit the thought of fuch accumulated de- coration. The room, in either of thefe cales, is not of that highly en- riched kind ; nor is the dial itfelf, though it may be rendered far from unpleafing to the eye, a piece of ornament at all like the others, of which we have treated. For thefe reafons the defign of the lower work in this Chimney muft be folid, without too much ornament; and all that be- longs to the continued part muft partake of the fame charader. Thus much premifed, that the ftudent may underftand every article, and its R r reafon. 154- C H I realon, ns we proceed in the defign, we fliall confider Separately the two parts ; or the Chi ninev' piece intended to fupport this fingular fuperftruc- ture, and the upper work itfclf. We have obferved in general, that the upper part in a continued Chimney-piece fliould be light; and for that rcalln have on all common occafions excluded the ufe ot the orders. But this is a kind altogether lingular. Its conftru(flion will therefore afford an exception from that rule, very allowable in its own nature ; and as we have direded that the whole of this upper work fliould be proportion- ed to the defign, we fliall here allow an order in the fuperftrudure, and that not of the lighter kind. Of the loiver Part in thh Chimney-Piece. The ftudent muft underlland, that he is to defign on this occafion a lower part of a continuedChimney-piece.whofecharadter mull: be ftrength, and whofe ornaments moderate. It is to be the decoration of a room where the tafte of high finilLing has not entered, and it is to fupport a plain, but folid luperftru.l at Rome remains of (tatues of Nero and Commodus of that charadl.r. Hence we call a building a Colollus, which is a great deal larger than the common fize. The amphitheatres of the antients, and the pyramids in Egypt are ol this kind. Thefe ate more properly called CololTal buildings thim ColofTus's, that term being ajtpropriated in a manner to ftataes, when uled dill:inifl!y in the word ; but it may be equally applied to any thing extraordinariiy great, or ia the iame knk as we wouid ufe gigantic. Colours, in painiing, are uled both as to the drugs themfelves and to thofe teints produced by thofe drugs vanoufly mixed and applied. The principal Colours ufed by painters are red and white lead, or cerufe, yel- low and red-ocres ; feveral kmds of earth, as umber, orpiment, black- lead, cinnabar, or vermilion, gumbouge, blue and green aflies, indigo biftre. i64 COL biftre, lamp-black, fmalt, ultramarine, and carmine. Of thefe Colours fome are ground in oil, others only in frefco, and others in water, and others for miniature. Painters reduce all colours under thefe two clafTes of dark and light Colours. Under dark Colours are comprehended black, and all thofe which are obfcure and earthy, as umber, biftre, &c. And under light Colours are comprehended white, and all thofe which approach nearefi: to it. Column, in architedure, a round pillar, to fupport and adorn a build- ing compofed of a bafe, a fhaft, and a capital. As every fulcrum is lo much the more perfedl as it is firm, or carries the app.arance of firm- nefs, hence all Columns ought to have their bafe broader than themfelves. As a cylinder and a quadrangular prifm are more eafily removed out of their place than a truncated cone, or a pyramid in the fame bafe, and of the fame altitude, the figure of columns ought not to be cylindrical, but grow lefs and lefs, like a truncated cone. Again, as Columns are more firm if their diameter bears a greater proportion to their height than if it bore a lefs, the greater ratio is to be chofen where a large weight is to be fuftained J and lefs, where a fmall weight is to be fupportfd. Further, as the defign of a Column is to fupport a weight, it muft never be fup- pofed without an entablature. Columns are diflf-rent in the different or- ders of architedture, and may be confidered with regard to their matter, conftrudlion, form, difpofition and ufe. With refpedl to the order, we have, Tufciin Column, that which has feven diameters in height, and is the fhorteft and mofl fimple of all the Columns. Its diminution is one fourth, that is, the diameter at top is three-fourths of the diameter juft above the bafe. Doric Column, has eight diameters in height, and its capital and bafe more enriched with mouldings than theTufcan. It diminifhes one-tenth part of the diameter at the bafe. Ionic Column, has nine diameters in height, and differs from the others by the volutes in its capital, and by its bafe. Corinthian Column, the richeft and mofl delicate of all, has ten dia- meters in height, and its capital adorned with two rows of leaves v^ith caulicoles, from whence fpring fmall volutes. J t diminifhes one- feventh part of the diameter. Ojnpclite Column, has ten diameters in height, and two rows of leaves in its capital, with angular volutes like the Ionic. It diminifhes one- eighth part of the diameter of the bafe. It may be obferved, that dif- ferent authors give different heights and proportions to Columns of the fame order ; and that frequently the fame author takes the liberty of dif- penfing with his own rules ; but the heights and proportions exhibited above are a mean between the extremes of all the reft.

There are now ufed CompafTes of various kinds and contrivances, accommodated to the various ufes they are in- tended lor. Composed CON 169 Composed Order, this term occurs in fome writers, and is im;i<^in- ed by the generality of readers to mean the fame thing with the Conu)0- fite. The lenfe of the word is in reality the lame, but cuftoin has made them exprefs what is different. The Compofite Order is, as we ihall fliew, one thing, a Compofed Order is capable of great and endlefs va- riety; it comprehends any compofition made at the pleafute of the archi- tedt, whofe ornaments are extraordinary and unulual, but havefomewhat of beautv. We fee a great deal of this workmanfliip in buildings, but it were well if there were lomewhat lefs of it ; for it is often very faulty. Composite Order, in architedure, is the lall: of the five orders of columns. It has this name from its being compounded of two or more of the others: The Latin word compofitus^ from which it is derived, fig- nifying compounded, or made up of others. The Corinthian is indeed by Vitruvius faid to be compofed of the Doric and Ionic, but the traces in that are not 16 plain as thofe of the Corinthian and Ionic are in this Compofite. The Compofite, like all the other orders, confirts of a bafe, (ha'"t, ca- pital, and entablature. The Corinthian bafe is ufed for Compolite order often, and fometimes the attic. Vignola gives the Compofite a difl:indl bafe, which differs from the Corinthi.in, in that it has only one afi:ragal between the two fcotias, the other being between the great torus, and firfl fcotia; but this is not much ufed. The ; cymatium, of which the fillet is one-third of the whole; then one and a half of the next grand divifion goes to the boultin and fillet over it, of which the fil- let is one feventh part of the whole. And ag^m, o le and a half of the next grand divifion goes to the cafement and hilet over it, of which the fillet IS one-fourth of the whole. And the iaft grand divifion goe» to the cymatium, of winch the fillet is one third part ot the wiioie. In the Cornice of the other falhion, he divides the whole height into fix parts i the upperrrioft of whica lieailo,vs to the o^ec, the fillet of which COR 177 which is one-fixth part ; the next grand divifion being fubdivided into three parts, the uppermoft of them" goes to the cymatium, (the fillet of which is one-third part) and the other two to the corona. The next two grand divifions are fubdivided into five parts, the uppermoll: of which goes to the cymatium (the fillet of which is one-third part) and the other four to the cartoufes. The next grand divifion is fubdivided into four parts J, three of which go to the boultin, and one to the fillet under it; and the laft grand divifions being fubdivided into four parts, three of them are for the cafement, and one for the cymatium, of which its fillet is one-third part. According to Scamozzi, the whole height of this Cornice is forty-two M. whereof the lift at the top is two M. the cima rcdla five and a half IVI, the lift one M. the cima reverfa two and a half M. the cartoufes feven M. the boultin four M. the lift one M. the fquare five M. the lift one M. and the boultin four M. Palladio makes the whole height of this Cor- nice forty-fix and a half M. of which the lift at the top is two and a half M. the cima redla (even M. the lift one and one-fourth M. the cima re- verfa three and a half M. the corona eight M. the cima rtcta over the modillions three and one-fourth M. the modillions feven and a half M. the lift one M. the ovolo or boultin fix M. the lift one and one half, and the cavetto or hollow five M. The whole height of the Corinthian Cornice, according to Vitruvius, is about one module j and he defcribes two forms of Cornices in this or- der ; in one of which, he divides the whole height into five parts ; the uppermoft of which goes to the ogee, of which its fillet is one-fixth part. Then one and one-fourth goes to the corona and cymatium over it, of which Ipace the cymatium is one-third part, and its fillet one-third of that. Then one and three-fourths of the next grand divifions go to the modillions and cymatium over them, of which fpace, the cymatium is one-fevrnth part. And the laft grand divifion goes to the boultin and fil- lets cvdr and under it ; and this being divided into three parts, thelov/er- moft goes to the fillet; and the other being llibdivided into fix part, five of them go to the boultin, and the other to the fillet over it. In the Cornice of the other faftiion, the whole height is divided into nine parts j of which the two uppermoft being divided into four parts, three of them goto the ogee (whule fillet is one-fixth of the whole) and the next two grand divifions go to the corona. The next two grand divifions go to the modiliicni, iVid the cymatium over them ; one-fourth of the fpace goes to the cymatium (whofe fillet is one- third of the whole cymatium) and the reft of the modillions. The next two grand divifions go to the boul- tin and fillet over and under it, v/hich fillets are each one-feventh of the Vi/hcle. And, the laft grand divifion goes to the cima at the foot of the Cornice. Z z , Scamozzi 173 COR Scamozzi makes the whole height of this Cornice forty-fix and three- fourths M. of whicli tiie lift of the cima redta is two M. the cima refta fix and a half M. the lift of the cima revcrfii one M. the cima reverfa three and one-fourth M. the half round one and one half M. the corona ftven and cne-half M. the cymatium three and one-half M, the modillions eight and a half M. the lift one M. the boultin five M. the lift one M. and the cima five M. According to Palladio the whole height of this Cor- nice is filty M. of which two and one third M. go to the lift of the cima red;a; the cima refta is eight and one-third M. the lift two-thirds M. the cima reverfa three M. the corona feven one-third JVI. the lift of the ogee over the modillions two-thirds M. the ogee two and two-thirds M. the modillions eight and a half M. the boultin four and one third M. the lift one M. the boultin five and a half, the lift one M. and ogee four and ahalfM. The Compofite Cornice. Vitruvius m.akes the whole height of it e- qual to the diameter of the column above, which is about fifty- two and a half M. He alfo delcribes two Cornices of this order of a different faftiion ; one of which he divides into two parts, the uppermoft of which goes to the ogee (whofe fiikt is one-fevenih of the whole) and the undermoft to the corona and cymatium over it; and this fpace being di- vided into four parts, three of them go to the corona, and one to the cy- matium, whofe fillet is one-third of the whole cymatium. Scamozzi makes the whole height of this Cornice foity-eight M. and Palladio forty-five VI. but about the height of each particular member, thty leave us very much in the dark. Goldman makes the height of the Tufcan Cornice one and one-third, and its prcjedture two-fifths M. the height of the Doric one and one-ihird, and its projedure two and two-filths. The height of the Ionic one and three-fifths ; its projedure two and two fifths. The height cf the Compofite one and three-fifths; its projedlures two and thirteen thirties. The height of the Corinthian one and two- fifths, its projedtures two and thirteen thirties. The Projcdure of the Cornice. It is an eflabliflied rule in archite the whole crane, with its !oad, turns upon its axis. Crank, a contrivance in machines, in the manner of an elbow, only of a fquare form, projedling from a fpindle, and ferving by its rotation to raife and fall the piftons of engines. It is alfo the iron fupport for a lan- tern, or the like ; alfo the iron made fart: to a ftock of a bell for ringing it. Crayon, or Pastil, among painters, a compofition of colours, re- duced to the texture of chalk, and ufed dry, in the form and manner of pencils, for painting on paper. Crest, ainong carvers, an imagery, or carved work, to adorn the head, or top of any thing, like our modern corniche. Crossette, in architecture, the returns in the corners of chambran- les, or door cafes, or window-frames, called alio ears, elbows, ancones, prothyrides. The Croflctte of a luthern is the plaifter or covering near a iuthern. Cboss-Grained, Timber is faid to be Crofs-grained, where a bow or fome branch rtioots on a part of the trunk of the tree; for the bough er branch (hooting forwards, the grain of that branch fhoots forwards alfo, and fo runs acrofs the grain of the trunk, and if it be well grown to- gether, it will fcarce be perceived in fome ftuffs, but only in working. Crown Post, in architedure, a port which in fome buildings ftands wpright in the middle, between two principal rafters. A a a Crown i82 C Y M Crowk, in architedure, the uppermon: mcmbfr of the cornice, called alfo corona, and larmier. Crowning, in architedure, any thing that finifhes a decoration. Thas acorniche, a pediment, a croteria, are called Crownings. Crypt A, a fubterraneous place or vjult, efpecially under a church, for the interment of particular families or perfons. Vitruvius ufes the word for part of a building, anfvvering nearly to our cellar. Hence, Crypto Poitico, a fubterraneous place, arched or vaulted, ufed as an underwork or pafTage into old walls. The fame words are alfo ufed for the decora- tion at the entry of a grotto. CuBATURE, is the cubing of a folid, or the meafuring of the fpace comprehended in a folid, as in a cone, pyramid, cylinder, &c. The Cubature has refped to the content of a folid as the quadrature has to the fuperficies of a figure j fo that the Cubature of the ;phere turns on the fame thing as the quadrature of the circle. Cube, in geometry, a regular or folid body, confifting of fix fquare and equal faces and fides, and its angles all right, and therefore equal. •The Cube is fuppofed to be generated by the motion of a fquare plane along aline equal to one of its fides, and at right angles thereto; whence it follows, that the planes of all fedions parallel to the bafe, are fquare equal thereto, and confequently to one another. Cupola, in architedure, a fpherical vault, or the round top of the doom of a church, in the form of a cup inverted. Curve, in geometry, a line, wherein the feveral points it confifls of, tend feveral ways, or are pofited towards different quarters. In this fenie the word is ufed in oppofition to a ftreight line, whole feveral points are pointed towards the fame quarter. Cutting, in painting, the laying one flrong lively colour over ano- ther, without any fliade or foftening. This hath always a difagreeable €ffed. Cylinder, is a round folid, having its bafes circular, equal and pa- rallel, in the form of a rolling-ftone. Cymatium, in architedure, a member, or moulding of the corniche, the profile of which is waved, that is, concave at top, and convex at bottom. This is oftentimes called alfo douc'r.ie gcrge, or gula reSlj gclctta by the Italians, but mofl ufually Cymatium, among us, being the laft or uppermoft member, q. d. the cima or fummit of the cornice. Some write it Simaife, from fwius, an ape, or camus flat-nofed ; but this etymology feems not proper ; the beauty ot the moulding confiding in its having its projedure equal to its height. M. Felibien indeed will not allow of this etymology; and contends, that the moulding is not fo denominated from its being the uppermoft member of the cornice, but upon its being waved, which is the opinion of Vitruvius. Vitruvius does C Y P 183 does not confine Cymatium to the cornice, but ufes it indifferently for any fimilar moulding, wherever he meets with it. In which he difl'ers from the moft accurate among the moderns. Felibien irakes two kinds of Cymatiums, the one right, and the other inverted; in the firft, that part which projects the fartheft is concave. In the other part that projedls farthefl is convex, called cida inverjaov falon. The Englifli architecfts do not ufually give the name of Cymatium to tbefe mouldings, except when they are found on the tops of cornices. But the workmen ufe the name ■ indifferently, wherever they are found. In/can C)matiiim confifts of an ovolo or quarter round. Philander makes two Doric Cymatiums; of which this is one. Baldus calls this the Lefbian aflragal. Lefbian Cymatium, according to Vitruvius, is what our architeds otherwife call talon, viz. a concavo-convex member, hav- ing its projcclure fubduple its height. Cypress-Tree, is one of the ever-greens, and very proper to mix with pines and nrs in forming clumps. The wood of the cyprefs is very valu- able when grown to a fize fit for planks, which it will do in as fliort a fpace as oaksj therefore, why fhould this not be cultivated for that pur- pofe, fince there are many places in England, where the foil is of a fandy or gravelly nature, and feldom produces any thing worth cultivation ? Now, in fuch places thefe trees would thrive greatly, and contribute to the pleafure of the owner, while growing, and afterwards render as much profit to his fucceffors as perhaps the belt plantation of oaks, efpe- cially fliould the timber prove as good here, as in the iflands of the Archipelago, which there is no reafon to doubt of: for we find it was fo gainful a commodity to the iHand of Candia, that the plantations were cal- led £/w F///^ ; the felling of one of them being reckoned a daughter's portion. The timber of this tree is faid to refift the worm, moth, and all putrefadion ; and is faid to laft many hundred years. The doors of St. Peter's church at Rome were framed of this material, which laf!:ed from Conftantine the Great, to Pope Eugenitus the Fourth's time, which was eleven hundred years, and were then found and entire, when the Pope changed them for gates of brafs. The coffins were made of this timber, in wfiich Thucydides tells us the Athenians ufed to bury their heroes; and the mummy cherts, brought with thofe condited bodies out of Egypt, are many of them of this wood. This tree is by many learned authors recommended for the improvement of the air, and a ipecific for the liin^s, as fending forth great quantities of aromatic and balfamic fcents ; on which account many ot the ancient phyficians of the eaflern countries ufed to fend their patients who were troubled with weak lungs, to the ifland of Can- dia, which at that time abounded with thefe trees, where, from the ef- fedls of the air alone, very few failed of a perfect cure. The i84 DEC The timber of Cyprefs is ufeful for cherts, mufical inftrumeiits, and other utenfils j for it refifts the worm and putrefadion, becaufe of the bitternefs of its juice. It never rifts nor cleaves, but with great violence. And it may be worth obferving, that the Venetians formerly made a con- fiderable revenue of it out of Candia, till the foreil; there was fet on fire, either through malice, (ir by accident, in the year 1400. It is reported it burnt kven years together, becaufe of the unftaous nature of the timber. The root of the wilder fort of Cyprefs is of an incomparable beauty, by reafon of its crifped undulations. It was anciently made ufe of in building fliips, by Alexander, and others. And fome will have it, that Gophir, of which Noah's ark was built, was Cyprefs. Plato preferred it to brafs itfelf, for writing his laws on. D Dado, in architedlure, the die, or that part in the middle of the pedeftal of a column which is between its bafe and cornice. It is of a cubic form, and thence takes the name of die. Deal, a thin fort of fir plank, of great ufe in carpentry. Deals are rendered much harder, by throwing them into falt-water as foon as they are fawed, keeping them thres or four days, and afterwards drying them in the air or fun ; but neither this nor any other method yet known, will preferve them from flirinking. Decastile, in ancient architecture, a building with an ordonance of ten columns in front, as was the temple of Jupiter Olympius. Decoration, in architedlure, whatever adorns a building, either without-fide or within. The orders of architecture contribute a great deal to the decoration j but then the feveral parts of thefe orders inuit have their juft proportion, charadters, and ornaments, otherwife the fined: order will bring confufion rather than richnefs. Decorations in churches are paintings, vafes, feftoons, &c. occafionally placed on or a- gainft the walls, but fo difcretionally, as not to take off" any thing from the form and beauty of the architecture, as is much pradtifed in Italy at the folemn feafts. Decorations alfo fignify the fcenes of theatres. The Decorations in operas, and other theatrical performances, muft be often changed, in conformity to the fubje(ft. The ancients had two forts of Decorations for their theatres ; the firft, called Verfatiles, having three fides or faces, which were turned fucceffively to the fpedtators. The other called Du£lih's, which were drawn or flidden before others. The latter fort of decoration is ftill in ufe, and to greater advantage among us than the antients, who were under a neceffity of drawing a curtain when- ever a change was made in the Decoration, whereas the change is made in a moment, and without fcarce being perceived upon our fhage. Decorum, D E S ,185 Decorum, in architedure, the fuitablenefs of a building, and its fe- veral parts and ornaments to tbe ftation and cecal! in. Vitruvius is very exadt in this point, and gives rules exprefsly for the appropriating or fuiting the feveral orders to their natural charadters ; Co that a Corinthian column Oiould not be fet at the entrance of a prifon or gate-houfe, or a Tufcan in tiie portico of a church, as has been done by fome of our builders, who have offended even in the difpofition cf the offices in our ordinary houfes ; we often finding the kitchen fet where the parlour fliould be; and that in the firil: and beil ftory, which fliould have been condemned to the lowed and the worft. Some iiuerpret Decorum to fignify the obferving a due refpedt between the inhabitant and habitation j whence Palladio concludes, that the principal entrance muft never be re- gulated by any certain dimenlions, but according to the dignity of the perfon who is to live in itj yet to exceed rather in the more than in the lefs, is a token of generofity, and may be excufed with fome notable em- blem or infcription, as that of the Co?iii di Bavilaiqua over his large gate at Verona, where probably there had been fome difproportion cjmmitted : Patet janua cor magis, i. e. My gate is wide, but my heart isfnore wide. Dentells, ornaments in a cornice, in fome degree refembli ng teeth, whence they have their name j dens, and in the plural dentes, in Latin, fignifying teeth. Dentells are often employed in the entablature of the Ionic order ; they are cut upon a little fquare member, and have the ap- pearance of a row of teeth, lome call this member the dcnticidm, and the Dentells, dentes or teeth ; others ufe denticle for the Dentt lis. They are in general indifferently called Dentells, dentils, and dentiles. The breadth of the Dentell fliould be half its heighth, and the interval or in- terdentation two-thirds of the breadth ; this is the proportion allotted by Vitruvius. Anciently, Dentells were ufed only in the loniccornice, but they have fince been introduced into others; the Greeks never put them under modillions, but later architedls have not been fo ftrid: in this ref- pe(fl, though both reafon and elegance recommend it. Design, in a general fenfe, the plan, order, reprefentation, or con- ftrudion of a building, book, painting, &c. In building, the term ichnography may be ufed, when by Delign is only meant the plan of a building, or a flat figure drawn on paper ; when fome fide or face of the building is raifed from the ground, we may ufe the term orthography; and when both front and fides are feen, in perfpedlive we call fcenography. Defign is alfo ufed, in painting, for the firft idea of a large work, drawn roughly, and in little, with an intention to be executed and finiflied in large. The art of painting has been by fome of the grcateft mas- ters divided into the Defign, or draught, the proportion, the expreffion, the claro-obfcuro, the ordonnance, the colouring, and the perfpedlive. It is the fimple counter, or outlines ot the figures or groupe intended B b b to iS6 D I A to be reprcfented, or the lines that terminate or cirdumfcribe them, fuch - Delign is fometimes drawn in crayons, or ink, without any ftiadows at all ; fometimes it is hatched, that is, the fliadows are expreffed by fenfi- bje outlines, ufually drawn a-crofs each other with the pen, crayon, or graver j fometimes again, the fliadows are done with the crayon, rub- bed fo as that there do not sppear any lines ; at other times the grains or flrckes of the crayon appear, as not being rubbed j fometimes the Dehgn is waflied, that is, the fliadows are done with a pencil in Indian Ink, or fome other liquor, and fometimes the Defign is coloured, that is, colours are laid on much like thofe intended for the grand work. The eflential requifites of a Defign are corredlnefs, good talle, elegance, character, di- verfity, expreffion, and perfpedive. Corredtnefs depends on the juftnefs of the proportions, and knowledge of anatomy. Tafle is a certain man- ner of conednefs, peculiar to one's felf, and is not to be defined. Ele- gance gives a delicacy that not only flrikes perfons of judgment, but com- municates an agieeablenefs that pleafes univerfally. The charader is what is peculiar to each objcrt, wherein there muft be diverfity, info- much that every thing has its peculiar charader to difiinguifli it. The expreliion is the reprefentation of an objedt, according to the circum- Itances it is fuppofed to be in. Perfpedive is the reprefentation of the parts of a painting, or a figure, according to the fituation they are in u^ith regard to the point of fight. Defigning is the art of delineating or drawing the appearance of natural objedts, by lines, on a plane. Dial, or Sun-Dial, an inflrument ferving to meafure time by means of the tliadow of the fun. This word is derived from the Latin, dies^ day, becaufe indicating the hour of the day. The ancients alfo call it fciathericum, from its fliewing the hour of its fliadow. Sun-dials are differently denominated, according to their different fituation, and the figure of the furfaces whereon they are defcribed ; as horizontal, ver- licle, equinodtial, polar, diredl, eredl, declining, reclining, cylindrical, 6cc. The firft Sun-dial that was fet up in Rome, was eredled by. Papyrius Curfor, about the year of the city, 447 : for Pliny fays, there was no mention on any account of time, but of the fun's fetting and rifing. This Dial was iet up in the temple of Quirinus, but it went not right. About thirty years after this, M. Valerius Mefi..'., fays Varro, being con- fui, brought out of Sicily, from the taking of Catana, another Dial, which he fet up on a pillar near the roflrum; but it not being made for that particular latitude, it could not go tiue. Neverthelefs they made ufe of it for eleven years, and then Marcius Philippus, who was cenfor with Lucius Paulus, fet up another that was more exaft. The Greeks alfo were a long time without clocks and Sun-dials. Some afcribe the inventions of Sun-dials to Anaximines Miktius, and others to Thales. Ihere D I A 187 There are many kinds of Dials mentioned by Vltruvius ; as one in- vented by Berofus the Chaldean, which was on a reclining plain, parallel almoft to the equinodial, there was an half circle upon it, and thence it was called Hemicyclus. Ariftarchus Samius found out the hemifphere- Dial. And there were fome fpherical ones with a needle for a gnomon. The difcus of Ariftarchus was an horizontal Dial, with its limb raifcd up all round to prevent the (hadow from extending itfelf too far. Dial-planes are of two forts. Firll:, fuch as are made on the wall of a building. Or, fecondly, fuch as are drawn on the tables of wood, commonly called Dial-boards. The firft fort, if they are made on brick work is done by plaiftering on the wall with lime, fand, and hair mixed ; this if well drenched witii linfeed-oil, after it is dry, or as long as it will drink in anv, and after- wards with oil and white lead, may be durable enough. But it will be a better way to temper the lime, fand, and hair with ox blood, which will be no great charge, but of great advantage ; for this mixture will equal in time the hardnefs of a free-ftonc, and keep the furface as much from the injuries of the weather ; but it mufi: be afterwards painted white. If you are to work on a ftone, the heft way is to drench the ftone with linfeed-oil, and white lead, very thin, till it will drink no more; then will the Dial you paint upon laft the longer, and be the better prepared to refift the ruins of time. Now for tables or Dial-boards of wood, they being mod common, we fhall give fuch diredlions for the making of them, as have been always found moft profitable and fit for the purpofe. The beft wood for this work is the cleared oak, and the reddilL fir, provided it be not turpen- tiny. There is but littl*- difference between thefe two woods as to their alteration by the weather, both being fubjedl to fplit, in cafe they are bound, and have not free liberty to rtirink with dry weather, and to iweli with wet. But as to their lafting, oak appears to be the beft of the two ; though good red fir that is hard will generally laft the age of a man, if it be fecured as fuch things ought to be. In working either of thefe kind of woods, firft cut the boards to fuch a length as you intend the deal board Ihould be, and fo many of them as may make up the breadth defigned ; then let them be jointed on the edges, and planed on both fides, and afterwards fet to dry; for it has been obferved, that though boards have lain in an houfe ever fo long, and are ever fo dry, yet when they are thus fhot and planed, they will fhrink afterwards beyond belief, if kept dry. When they have been thought to have been dry enough, and will flirink no more, let them be again (hot with good joints, and let every joint be fecured by two wooden dove-tails, let in crofs the joint on the backfide ; but let this be done when the boards are glued together, ' and well dried. After they have been thus glued, and the joints are fufii- cieutly i88 D I A ciently dried, then let the face of the board be well planed, and tried every way, that it may be boih fmooth and true, and all of a thicknefs, as pannels of wainfcot are commonly wrought. The edges mufl be thus true and even, that they may fit into the rabet of a moulding put round it, juft as a pannel of a wainfcot does in its frame. This will give liberty to the board to fhrink, and fwell without tearing; whereas mouldings that are nailed round the edge, as the common way is, do fo rcftrain the motion of the wood, that it cannot flirink without tearing j but board wrought after this manner will laft a long time, without either parting in tiie joints, or fplitting in the wood. Dials are fometimes drawn on planes lined with copper or lead, that they may be free from (plitting or tearing; but a board (if it be prepar- ed as above direded) is thought preferable to them in many refpedls, as it is much cheaper: belides, lead and copper too, will fwell with the heat of the fun, and grow in time hollow outwards or convex, inflead of a perfedl flat, fo that the truth of its fhadow will be much injured. The colours will be apt to peel from the metal, and the Dial will by that means be fooner defaced, than if it were painted on a wooden plane. Before you begin to paint, it will be abfolutely neceffary to make a draught of your Dial on paper ; your board being ready, and your colours prepared, then proceed as follows. Take Spanifh brown, that has been well ground, and mixed moderate- ly thin, and with a large briflle-brufh dipped in it, colour the board or plain all over, on the back as well as on the fore fide, to preferve it the better, fo that no part be left uncoloured ; this is called the priming of a Dia^ When this firft colour is dry, do it over ^gain with the fame coloui^ tempered fomewhat thicker; and when this is alfo dry, you may, if you pleafe, do it over again with the fame colour ; the work will be the better, and laft the longer. This being done, then colour the face of the Dial plane over with white lead ; and when that is dry, work it over again three or four times more, fucceffively after each drying j and fo will the face of the Dial-plane be fufficiently defended againft the vio- lence of the weather. When the laft colouring of the white is drawn, you muft draw on the plane, with a black lead pencil, a horizontal line, fo far diflant from the uppermoft edge of the Dial, as your difcretion {hall think fit, or your experience finds fhall be moft becoming the plane; then fet out the margin of the Dial with boundary lines for the hour, half hour, quarters, and quarter-divifions of the Dial, as you fee done in moft Dials. When the margin and boundary lines of the Dial are fet out, then take your paper-draught, that has been fairly drawn, and place the horizontal line of that, on the horizontal linethat you beforedrew on the plane j in doing of which, obfcrve to place the centre according as the fituation of your plane, for convenience fake, requires. Thus if your Dial D i A 189 Dial be a full fouth-Dial, then let the centre be exactly in the mi.ldle of the plane; but if your Dial decline from the fouth, either eaft or weft, then place not the centre of your draught in the centre of your plane, but nearer to one fide or other of it, according as it declines, having alfo reward to the quantity of "its declination. 'Asfor example; if your Dial decline eaft wards, then let the centre of your draught be placed between the centre and the eaftern fide of your plane, the quantity thereof mud: be according as your Dial declines : if it declines but a little, then place the center of your draught but a little from the center of your plane ; and if it declines much, place the centre of your draught the more out of the centre of your plane. The reafon of advifing this, is that by fo doing you may gain a greater diftance for thofe hour-lines, which in declining planes, fall nearer together on one fide than they are on the other ; for which reafon, it is ufual fo to do in ' declining planes, except they decline far, as between eighty and ninety de- grees j for in this cafe, they are commonly drawn without centres, to gain the greater diftance for the hour lines. When the paper draught has been thus artificially placed on the plane, and faftened with pins, or fmall tacks, then let the draught of it be transferred on the plane, by laying a ruler over every hour and quarter divifion, and where the ruler cuts or interfeds the boundary lines of the margin, there make marks, by drawing lines with a black lead pencil, of fuch a length as each divifion r. quires, or is defigneJ by your boundary lines, oblerving always to draw the hour and half hour lines quite through your margin, that they may be guides for the right placing of the figures, and for a fmall fpot that is ufually placed in the. margin, right againft the half hour. When this Dial-draught has been thus transferred to the plane itfelf, you muft not forget to draw the fubftdar line according as it lies in your draught, to be a guide for the right placing the ftile or cock ; for you muft be very exaft in every particular, or elie the Dial will not be right. Every thing that is required being taken from the draught, and tranf- ferred to the plane, then take the draught off, and with vcrmillion well ground and prepared, let the boundary lines of your Dial, as alfo the hour, half hour, and quarter divifion be drawn therewith ; let your co- lour be as thick and as ftill as you pofTi'r.ly can work it, fo as to draw a clear and fmooth line ; becaufe this is to be done but once. When your Vermillion lines are drawn, then make the figures with lamp-black, and a fpot in the middle of the margin, right againft the half-hour line, and, if you pleafe, in the margin at the t.jp of your plane, you may put the date of the year, your name, and fome fentcnce as is ufual in things of this nature. Then fit in vour cock, fo as to make right ang'es with the plane. So (hall your Dial be drawn, and finiftied in all refpeds as a plain Dial ought to be. C c c Before^ 190 D I A Before we difmifs this article, it will be necefTary we dired the fludent to the heft authors who have wrote on the fubjedt of Dialling. Stirrup's Dialling will be found of great ufe to the rtudent, teaching him the- knowledge of the fphere, that he may underfland the nature and reafon of Dials. Collins's Dialling is a very ufeful book. In Leybourne's Dialling you have the befl: inflrudlions for drawing eafl: and wefl Dials, and for decliners. Laftly, Collins's fedor on a quadrant, in which you have reprcfented the cut of a fcale. that by knowing the declination, gives all the requifites of an upright decliner, by infpe6tion only, with as great accuracy, as the moft corrtd: calculation j befides, it teaches the way of drawing the hours of a Dial by a tangent line, and alfo by the fcale of hours ; two of the bell: and mod expeditious ways that ever have been yet difcovered. Dialling Globe, an inflrument of brafs or wood, with a plane fitted to the horizon, and an index, fo contrived as to give a clear lUuf- tration of the principles on which Dials are made. Dialling-Lines, or Scales, are graduated lines placed on rulers, or the edges of quadrants and other inftruments, to expedite the conftruc- tion of dials. Dialling-Sphere, an inftrument made of brafs, with feveral fern i- circles Aiding over each other upon a moveable horizon ; ferving to de- monftrate the nature of fpherical triangles, as well as to give the true idea of drawing dials on all f Tts of planes. Diameter, in geometiy, a right line paffing through the center of a circle, and terminated at each fide by the circumference. The chief ■ properties of the Diameter are, that it divides the circumference of a cir- cle into two equal parts. Hence we have a method oi defcribing a femi- circle upon any line, aiTuming its middle point for the center. The Di- ameter is the greateft of all chords. The Diameter of a curve is a right line that bifeds the right lines drawn parallel to one another; and are either of a hnite or infinite length. Although a right line, bifedingall parallel lines drawn from one point of a curve to another, is taken in a ilnO: i'enic only for the Diameter of a curve-line, yet it may not be amifs moie generally to define a Diameter, in faying, that it is that line, whe- ther right or curve, which bifedls all parallels drawn from one point of a curve to another; fo that, according to this every cuive will have a Diameter; and thence Sir Ilaac Newton's curves cf the fecond order have all either a right lined Diameter, or elfe the curves of lome one of the conic fedtions for Diameters ; and many geographical carves of the highefl orders may alfo have lor Diameter curves of more inferior ones, and that ad injinitum. Diameter of a Sphere, is the Dism.eter cf the femi-circle, by whofe rotation the fphere isgerieratcd ; in which knfe it is the lame with axis. Diameter D I M 191 Diameter of a Column, in architedture, its tbicknefs jufl: above the bafe. From this the module is taken, which meafures all the other parts of a column. Diameter of the fwellings is that taken at the height. Diameter of the diminution of Columns is that taken from the top of the Oiafts. DiASTYLE, the term by which the old architeds expreffed that inter- columniation, or fpace between columns, which confifted of three dia- meters of the column ; others call this a fpace equal to four diameters. The word does not determine any thing from its derivation, which is only from the Greek Six, between, and juAoj, a column, fo that it may exprefs one diftance between as well as another. Die, a term ufed to exprefs a fquared naked piece. Thus the body of a pedelfal, which is that part between its bafe and its cap, is called the Die of the pedeftal. It is alfo a name by which fome call the abacus. Digging, the Digging of the ground for cellars, and for the founda- tions of buildings, is commonly done by the folid yard, containing twen- ty-feven folid feet, which is commonly counted a load. Therefore take the dimenfion in feet, multiply the length by the breadth, and the pro- dud by the depth, and then divide the laft produdt by twenty-leven, and the quotient will give the content in folid yards. D I MENSION, is the extenfion of a body conlidered as capable of being ineafured. Hence, as we conceive a body extended and capable of being mea(ured in length, breadth and depth, we conceive a trine Dimenfion, viz. length, breadth, and thicknels. The firft is called a line, the fe- cond a furface, and the third a folid. Diminution, a term expreffing the decreafe in thicknefs in a regular column. In Gothic buildings we lee pillars of an enormous height in proportion to their thicknefs, and all the way up of fome diameter j in regular building the column diminilhes in the upper part, and it is na- tural that it fhould do fo, for the hrft columns were parts of trunks of trees, and they muft have from nature this Diminution, which the an- tients had the judgment to preferve in the iliape of their artificial co- lumns. The Diminution generally begins from one-third of the height of the column; fome make it begin from the very bafe, lo that the co- lumn is fmaller all the way up, but the fiilf is the general and the bcft method J this other has not nearly fo good an effcdt. The Diminution in the Tufcan order is ufually the greateft of all ; it is commonly made a fourth part of the diameter of the column at the bafe; but anticnt buildings do not warrant this; in the Trajan colun:H the Diminution is but one ninth of the diameter. The Dimuiutions arc \t\-y indifferently proportioned in columns of the fame order m difierent antique remains ; and Vitruvius vv'ould have this contradion in thicknels proportioncQ to theabfolute height of the column, rather than to the con- fidcratioa 192 D I S fiJeratlon of any particular order : if a colutnn be fifteen feet high, he direds the Diminution to be one fixth of the diameter ; and if it be fifty feet, he would have it only one eighth ; but the pradlice of the antique, as w-ell as later architeifts, differs extremely upon this head ; fcarce any tiling is fo far from being determined. DiPTERE, a term ufed by the ancients to exprefs a temple encompafled with a double row of columns; it is derived from the Greek ^nrji^o';, formed of J"!?, twice, and z/l^^o;, a wing, and exprefles a building with two wings. Wlien a building was encompafled with a fingle inftead of a double row of columns, it was called the p/et/Jo Dipterc^ or Jal/e Diptere j the two rows formed of a kind of porticos, which they called wings. Disposition, in architecture, the juft placing of the feveral parts of an edifice, according to their proper nature and office. Difpofition of pictures and paintings j the manner how, and where noblemen and gentlemen, who are pofl^effed of a choice colledion, fhould have them placed in their different apartments, i. Antique works, or grotefque, may become a wall, and the borders and friezes of other works; but if there be any draughts in figures of men and women to the life on the wall, they will be bell of black and white, or of one colour height- ened : if they be naked, let them be as large as the place will afford : if of marble columns, aqueducts, arches, ruins, and cataradls, let them be bold, high, and of large proportion. 2. Let the beft pieces be placed to be feen with fingle lights ; for fo the fliadows fall naturally, being always barred to anfwer one light ; and the more under or below the light, the better, efpecially in mens faces, and large pieces. 3. Let the porch of entrance into the houfe be fet out with ruftic figures, and things rural. 4. Let the hall be adorned with fliepherds, peafants, milk-maids, flocks of fheep, and the like in their refpedive places, and with proper attend- ants ; as alfo fowls, fifh, and the like. 5. Let the ftair-cafe be fet off with fome admirable monument or building, either new or ruinous, to be feen and obferved at a view paffing up ; and let the cieling over the top- flair be with figures forc-fhortened, looking down out of the clouds, with garlands, and cornucopias. 6. Let landlkips, hunting, fifhing, fowling, hiftories, and antiquities, be put in the great chamber. 7. Let the pic- tures of the king, prince, or other great perlonagesj or their coats of arms, be placed in the dining-room. 8. In the inward, or with-draw- ing chambers, put other draughts of the life of perfons of honour, inti- mate or fpecial frie;ids, or acquaintance; or of artifts only. 9. In ban- qucting-rooms, pkce chearful and merry paintings, as of Bacchus, cen- taurs, fatyrs, fyrens, and the like, forbearing all obfcene pidures. 10. Hiftories, ferious fubjcds, and the beft works become galleries, where any one may walk, and exerciic their fenfes in viewing, examining, de- lighting, judging, and cenfuring. 11, Place caftles, churches, or fome fair D O O 193 fair buildings in fummer-houfes and ftone-walks. In terrafl'es, put baf- cage and wild works. Upon chimney-pieces only landlkips, for they chiefly adorn. 12. Place your own, your wife and childrens pictures, in your bed-chambers, as they beft fuit the private rooms, and are moft a- sreeablc to modefty, lead (fays an author) "if your wife be a beauty, " fomc wanton guelt fliould gaze on it too long, and commend the work «' for her fake." 1 3. In hanging picflures, if they hang high above reach, let them bend fomewhat forward at the top, becaufe, otherwife, it is ob- ferved, that the vifual beams of your eye which extend to the top of the pidure, appear further off than thofe of the foot. Distemper, in painting, a term u fed for the working up of colours with fomething befides water or oil. If the colours are prepared with water, that kind of painting is called limning ; and if with oil, is called painting in oil, and limply painting. If the colours are mixed with fize, whites of eggs, or any fuch glutinous, or unduous matter, and not with oil, then they fay it is done in Diftemper. In this manner the admira- ble cartoons, late at Hampton-court, but now at the Queen's Palace, are painted. The greatcfl; difadvantage of difteuiper is, that it has no glit- tering, and all its colours look dead, by which means they appear alike in all forts of lights, which oil colours, or even colours in Diifemper, when varnifhed do not. Distribution, in architedure, the difpenfing of the feveral parts and pieces which compofe a building, as the plan diredfs. The Diftnbu- tion of ornaments, is an equal orderly placing of the ornaments in any member of architefture. DiSTRYGLYPH, in atchitedlure, the fpace between two triglyphs. Dome, in architecture, a Ipherical roof, rajfed over the middle of a building, as a church, hall, &c. by way of Ci-owning. Domes are the fame that the Italians call couppola's, and we cupola's. Vitruvius calls them tholi. They are generally made round, or refembling the bell of a great clock ; but there are ibme inftances of fquare ones, as thole of the Louvre; and alfo feme of them are in the form of Polygons, as that of the jefuits church in the Rue St. Anthoine at Paris. Domes have com- monly columns ranged around their outfides, both for the fake of orna- ment, and fupport to the work. Doors. Two things are to be confidered in the defign of a Door, the ■ firft its aperture, and the fecond its ornaments. Thele muft both enter ' into the mind of the archltedt who is defigning an edifice, or he will ne- ver proportion or adapt it to the itrufture. How often do we fee in Lon- don, Doors wJiich appear not to belong to the houfe, but to be joined to it againft nature, not raifed with the building. It is comn:ion to lee Doors whole breadth occupies near one half of the extent in front ; and in Do- ver-ftreet there is one whofe top covers half the window placed over it D d d ia 194 D O O in the upper flory. This is the error of thofe who mean to be magnifi- cent ; but the oppofite is too common in plain houfes. Doors are put which feem to fay, no fat man comes into this houfe, and they always difgrace the whole building. The variations in the antique are in this inftance very great; and from this it was that Palladio evaded giving rules for the dimenfions of Doors in proportion to houfes. He was fenfible he could lay down none againft which fome inftance might not be brought, in thole buildings which were allowed mafterly in their kind; and he therefore left it undetermined. There are many things in which the antient architedls have erred, and it will be a double error in us to copy their faults. They did not in general make the aperture equal all the way, but contraded it upwards, This mufi: have had a iftrange effed. A Door narrower at the top than the bot- tom mull have appeared a deformity in any building. The limits of thefe things are not fixed at any certain point, nor are the powers of genius fettered by fuch boundaries. While we admire the dignity of the Gre- cian or the pomp of the Roman Doors> let us fee alfo this contraction as an egregious error, and if we refer to Palladio, or to the oracle of Palla- dio, Vitruvius, on this account, let it be to diflent from their opinions. With regard to the Italian, he was loft in the diverfity of what he read, and what he faw ; as to the Roman, he fcems to have received it as a law in the fcience, that there (hould be this contradion ; and when he direds that in Doors of more than thirty feet height in the opening, there (hould be no contraftion of the diameter, his commentator Philander, who rare- ly milfcs his lenfe, fays this" was, becaufe at that height the nature of vi- lion anfwered the fame purpofe; and the contradlion was given to the eye by diftance. The archited: will fee by this free difquifition, that the antients are not proper inftrudl ors in the dimenfions of Doors j how much foever we may learn from them refpecling their ornaments. He will fee alfo, that the moft famous of the moderns has left him uninformed on this head : and if he looks into the common books of defigns he will find nothing but abfurdity. With refpedl to the height ot Doors in the aperture, there is an univer- fil law in reafon, though not oblerved ; there is a certain heigot below which they niufl: not be, though for dignity and proportion the field in which they may exceed is almoft unlimircd. The human ftature is the mark for the Icaft height that can be proper; he who makes a Door is not to defcend below this efrabhfhed proportion. For the loweil Door then the height muft be fuch, as that a man of the higheft common fta- ture may go through it without Hooping, This limits the mealure to Iik feet} below this the Door of no houfe Ihauld be made, even of the plain- ell ; but ail above is left to fancy guided by the general idea of propor- tion. D O O 195 tion. The height being thus determined, the breadth conies into confi- deration; the fides muft be fj diftant, that they muft not reduce a man t o enter with his arms in any particular pofture j as he is to go in without Hooping, fo he ought to be able to walk in at eafe. The fmalleft dimen- fion therefore in breadth that can be allowed is three feet ; and this being half of the given height has a very good effedt in refpedl of general propor- tion. Thefe are the rules laid down by nature, and thefe being allowed as truth, become the foundation of all the other proportions. While we are near this, we are fure not to err ; and this ought always to be kept in remembrance for that purpofe. He would have reafon to complain of the confined laws of the fcience, who fancied that from this every Door muft be made the exadt double of its breadth in height ; there are peculiar con- ftrudions which require particular meafures ; but as in all other cafes there are bounds which muft not be tranfgrefi'ed, fo in this there is a la- titude, as we ftiall fhew, within which the fancy may rove, but which it muft not pafs. We have faid, that for the plaineft Doors the proportion of height to breadth muft be double; this is to be a little varied at the pleafure of the architedl, and he muft thus employ his liberty. If the front of the houfe extend confiderably in breadth, in proportion to the height, the Door muft be adapted to it, by having a proportion of breadth fomewhat too great for its height ; upon the preceding principles, and in the fame manner, if the building be one of thofe which rife to a height without any great breadth, the Door for it fliould be made a little more than twice as high as broad, to accommodate the figure of that as of the other parts to the form of the whole. Thefe are liberties he is to take, but they muft be taken with difcretion ; great variations from common proportions will be always wrong ; and it is never needful, be- caufe a Door is fo obvious a part, that lefier will be I'nen. The form and dimenfions of Doors having thus been eftablilhed upon fome principles, we are to confider their pofition. This varies according to their diftance from the level of the ground, and is to be governed by the height of the floor to which tliey belong. In the plair.ell and molt ordinary houfes the Door is upon the level of the ground, but this is v/rong for a very obvious reafon. There is to be fome fettling exptdvd in the houfe, and experience flicws, that the ground in all inhabited places na- turally riles in furface. Tlieretore a houfe \yhofe floor of entrance was placed originally upon the level of the ground, will in a few years, fiom the concurrence of thefe two accidents, or from one of them, be below that level ; the Door will then ftand below the lurface of the ground, and we mult go down flairs into the houfe ; this is to be avoided both for fhew and lervice. A floor under the level of the ground will be damp, and the Door, if well proportioned at firft, it will be too low for its breadth, at leaft it uill appear fo, which in this relped is the fame thing. This is a reaion 196 D O re;ifon why a Door fhould never reft upon the level of the ground j but if againft all rule the builder or the owner will have it fo, the proportion to be obferved is this j it mufl: be made fomewhat high in an over-proportion to the breadth, becaufe the eye at firft will reduce it to the appearance of regularity, and probably accidents afterwards will place it below it. Kence is derived a principle that ought to ftand as unalterable in itfelf; that the more the Door of a houfe is raifed above the level of the ftreet the more its breadth fhould exceed the natural proportion with refpedt to height. This depends upon the nature of vifion, which in thefe near ob- jedls ought always to be confulted ; for the higher the Door is placed the. narrower it will appear by diftance, and therefore the broader it fliould be made in the reality. Thefe are points which deferve to be confidered much more ftridtly than they are, for upon them depends entirely the pro- portion. In the earlieft architedlure we find, that the cuftom was to place the Door at a confiderable height above the level of the ground j and in all magnificent buildings it ihould be thus raifed, and in others in propor- tion to their fize. The raifing the Door after the old Greek manner gives many advantages. The floor to which it opens has elevation, bet- ter air, and the advantages of profpedl. There is the benefit to it by flights of fleps, which, whether fingle or double, are of great ornament, and may be carried to any degree of elegance, according to the pleafure of the purchafer ; it alfo gives a good floor for the ufe of the fervants. For all thefe reafons we fee it befl; to give the Door an elevation, and we have diredled the architedl: to the only method by which one of this litua- tion ever can be rendered truly graceful. We are now naturally led to the ornaments of Doors, and -are to pro- pofe, as their firft and greateft decoration, the ufe of the orders. They are the nobleft and mofl" graceful part of architecture, and are therefore fuited to what is to make the firft impreffion, as a Door naturally does. Their expence is no where an article of fo little confideration, becaufe they are here fmaller and fewer than in the common ufes ; and the archi- teft of tafte has this realbn to be pleafed with them, that he has in their conftruction a fcope for all the boldnefs of his genius, and the beft flights cf his regulated fancy. Great variations are authorized by the remains of antiquity in the conftrudlion of every one of the orders; in the orna- ments of Doors there is full fcope for the imitation of all thofe of the antients, and for the devifing new ones; and from this may arife a dignity and grace unknown hitherto in architedlure. From thefe he may feledt what will beft luit the purpofe of every particular Door j for it will be proper for him to give the greateft heights to his columns and their capi- tals, where the Door is to be, according to its fituation, narrower th^n ufual in refpedl of height; and on the contrary, to feleft thofe columns fiom among our examples of each order, which are loweft, where the Door D O O '97 Door is broader than the exafl proportion of height would didate. This is the true uCe of thefe remains of the antique, and by Inch a method of employing them they will obtain as much credit for the architect, as in a random choice they would difgrace him. One thing remains to be obferved with refpeft to the diminution of columns ufed in ornamenting Doors, that the greater this is, the lefs they are fuited to the purpofe. This is one of many realons that ought to banifh the Tu'can order from this piece of fervice. Its diminution is not only the greatcft of that of any order ; but it is greater beyond all proportion, and looks as if ill-formed, where it is made with ever fo much truth. The other orders are no way more happily ufed than for this purpole ; their diminution is tlie great grace of their forrr, and it is never fiiewn fo plainly or confpicuoufly. The upright of the Door-cafe, before which it ftands, is a meafure to the eye, and the whole being near,, and the form of the column diftind, the diminution is feen in the whole outline. This is a very obvious reafon for preferring columns to the vul- gar cuftom of pilaitcrs upon this occafion ; but at the fame tmie, as we have obferved already, the peculiar diminution of the Tufcan being too great to be borne, on fo near and fo diftind a view, fliould exclude it fiom this ufe in the ornaments of Doors. Having treated on the ufe of columns in the ornament of Doors, we now proceed to fhew the young, archited the ufe of the more elegant orders in Doors. The greateft decoration of Doors is by means of the orders. Tlie Tufcan is in general the leaft fit for the purpofe; therefore there remain to be confidered only the two more rich and elegant to be appropriated to- this ufj. A plain opening left in the wall was doubtlcfs the firft Door- way, and it continues the plained j it were well if we could not fay, it would be to the advantage of many decorated entrances to good houfes, if all theexpence could be removed, and the opening left naked as it came from the hand of the bricklayer. From the plain Door-way, the advance to that ornamented with the lowefl: order is by many Itages, and in all- thefe there is luch a thing as plain propriety, which only a mifguided fan- cy could tranfgrefs. The great error is that of crowding ornaments of a fuperior kind into a work of an inferior; this is as abfurd in the leaft things as the greateft. The capital of the Corinthian order put upon a Tukan column, could not be more monftrous than the bringing in here the decorations of one kind to the plan in another. Vv'hen the Doric with its beft proper decoration docs not appear rich enough, inftead of adding what is unfit, the architect Ihould choofe the Ionic,, and the fame rule holds here univerfally; let the builder fee in this light. If a Door with an architrave cannot be made rich enough by proper fculpture to- pleafe the eye of the pofteftbr, let him not introduce into it the deco- rations appropriated to other kinds; but at one advance from that plan E e e to 198 D O O to defign with an order, and laying afide the other entirely adhere to this. There is nothing ahfurd but from the mixture of improper parts; and ncthing is ridiculcus tiiat is not ablurd ; therefore let him keep only pro- priety in his mind, and he will be fu'-e to elcaps ce;ifure. The plaineft Door that has proportion in its dimenfion-, andpropriet, in what IS placed about it by way cf ornament, will give fitisfadiion not only to the judicious, bijt to every eye, while ill-judged ornaments raiie contenipf. Let it be an univerfa! rule deduced from this principle, that where there are not columns introduced, there fhould be no refemblance of them. With what difguft does the judicious eye lock, at the Door vvheie the conceit of the architecfl has formed a half col. imn out of fome of the mouldings, which running up to enclofe a compartment above the Door, together with it, fifteen diameters in height, and has a fancied capital to crown the abiurdity ? What contempt muft this unnatural Gcthic piece of bufinefs raife in all who look upon it ? If the architedl VvilJ have any refemblance of a column, let it be a column in due pro- portion ; a little judgment will diredl how to di pofe the compartment above ; and leis expence than pays for this abfurdity will iinifh the work with propriety. The original thought of decorating a Door- way was no more than by a pldin cafe of u-ood with a bead at its edge. The fliarpntfs of the cor- ner, or angle of the brick- work was difagreeable, as alio its roughnefs; and being a fliarp Cv-lge of a weak fubftance, it was broke and made ir- regular by every little accident. This put it in men's minds to cafe or cover it with board ; and the inconvenience of its fharpnefs made them cut a moulding, by way of bead, or plain allragal, all the way its length. Thus were Doors ornamented in the earlieft times of building, and as they were then under the condudl of men of true tafte, the)' were able to proportion the breadth of the wood- work to the opening of the Door, and tciminating at the extreme edge with another allragal, there was a plainnefs, but ftill there was a propriety and ufe ; and when thefe unite, there never wants beauty to the dilberning eye. As the plain breadth of boards offended the eye, the old architeds carried up along its middle a feftoon of various contrivance. The oak leaves and fruit gave the firft hint ; the olive lucceeded this, and afterwards the vine ; this gave a beau- tiful freedom from its ramping figure, which they knew how tu rellrain with judgment, and from this they reached the acanthus leaf, in their judgment the heighth of vegetable beauty. From thence they began to diveifily the felkon with fymbols and inftruments of lacrifice, and thencs they ccme 10 hieroglyphics. As the plain cafe of the Door received t!)is ornament, the bead at its edge fwelled by degrees, by the addition of more and larger mouldings, to an architrave. This was finely varied, and the freeze which crowned it at the top received all the decorations of Iculpture D O O 199 fculpture given to the pannel. Thus far advanced, the orders were intro- duced naturally, and here among thofe great builders ended the decoration. Thus began, and thus was raifed to perfedlion, the decorations of Doors among the Greeks and Romans. Here they flopped, for they had judg- ment ; but the luxuriant fancy of thofe who fullowed them, admiring their works, but wanting the tafte which regulated them, flew into every abfnrdity that the whole fcope of things could afford. Of this we fee inftances in many expenfive works which fland, to difgrace our country ; and we have models of them, and of others as ridiculous, propofed for imitation, and publiflied, as the titles fay, for the inftruclion of builders. We have Ceen architedlure, a fcience founded upon the founded princi- ple, difgraced by ignorant caprice, and fafhion lately has attempted to undetermine and deftroy it by the caprice of France, and by the whims of China. How muft it difguft a man of true t aft 3 to fee, "in fome of the beft buildings in France, famed as it would pretend, for the encouragement of arts, Corinthian capitals made of cocks heads, inflead of leaves of the acanthus ? And this mofl: abfurd variation from the figure and defign of the antique, give to its inventor the glory of having added a fixth order. It is called the French, and let them have the praife of it; the Gothic fhaflsand Chinefe bells are not beyond or below it in po-ornefs of imagination. Upon the mofl impartial review we ftiall find, that nothing in greatnefs or in grace, can compare with the Greek and Roman archi- tecture; therefore let us employ nothing in the place of them. The richnefs of an order depends upon its natural form; lut a great deal may be done in the article of improvement and elegance, by the ma- terials that are employed, and by the additions of fculpture. No abfo- lute diredion can be given in this reipe&, for the expenceof the differ- ent kinds is fo various, that the choice of the proprietor alone can be confulted. We may confider the materials for the orders intended for this ufe to be, in England, three; wood, flone, and marble: of thefe three wood is by much the mod univeri'al. It is the cheapeft in itfeif; it is fufficiently lalling ; and it receives the chiffcl freely, and retains its fmalleftftrokes very fafely. Therefore this is to be confidered as the na- tural material in England, and it ferves equally well either for the outfide Doors or thofe within. Stone has an air of grandeur which wood has not ; ror can any painting or any artifice give it ; but this is naturally to the outfide Door. Marble has, with a much greater dignity, a noble and peculiar elegance. It ferves equally within Uoors and without ; but the weight of this and ftone fliould confine them Vv'ithin the ground floor. Vv^e have inftances of enriching even marble columns, by placing upon them in the Corinthian order, capitals of brafs ; but this is an uunUural and foolilh addition. The colours of the brafs and the marble are fo dil- terent. 2C0 D O O ferent, they never can agree one with another as two parts of an entire body ; and the marble itfelf bears to be wrought with all the needful raf- flinfTs, and fliews them very happily. The addition of b^a^!^ therefore we wholly rejccfl ; it is expenfive, unnatural, and unb'.coming. Such as have been at the expence of graniteCorinthian columns on feme occaiions, have added capitals of gilded brafs ; which have had their admirers. The reafon of cafting their capitals in brafs was, becaufe we have not tools to cut them in the granite : but in this cafe it would have been better to have wrought this fine material into columns of an inferior order, as the Doric, where the capital being plain, the whole might have been uniform, and of a piece ; for undoubtealy the fame tools, and the fame hands, which could round the column, could alfo form the capital of this plain, tho' noble, order. There is no part of an edifice in which fculpture can be fo happily em- ployed as about a Door-cafe : every eye perceives it ; and it does not in- fer a neccfTity of continuing the fame work throughout the houfe j for a Door is a detached piece ; and it is expedted to be ornamented. We fee in many inflances a great deal of labour in this way employed upon Door-cafes -, but it is rude, harOi, and unfinifhed. It is better one good piece, though fmali, fhould ftand in fome confpicuous part alone, than that all this Icattered indifferent work fliould glare without approbation. If our painters want genius to give defigns in this kind, the treafures of antiquity arc inexhauftible ; and our frugal ancelfors, like ourfelves, have made fo little ufe of them, that they are new. What a variety of deco- ration might the ingenious fculptor adopt from the ruins of Palmyra? How bold and noble are the bas reliefs of the Parthenian ? Indeed what is there of the ornamented kind, among all that is left us of antiquity, where various lefTons may not be found under this head ? Which of all their works do not afford hints for the fculptor of genius to follow ? Whilewe prefer the enriching our Door-cafes by the hand of art to the more expenfive treafures that are to be had from nature, we muft obferve, that feme regard fhould be paid to each. The materials fliould be adapted to the workmanfhip ; for it would be a pity to bcffow labour and genius upon fuch materials as would difgrace them j or upon fuch as would not long enough fupport themlelves againft the force of accidents. Stone moulders quickly whenexpofed to the air; therefore when a very elegant Door-cafe is intended for the outfide, the proprietor fhould not grudge the ufe of marble. In the fame manner with regard to the Door-cafes for rooms in which thefe orders fhall be admitted, the choice naturally falls upo.i wood; but there is as much difference between wood and flone, as between ftone and marble. Our fathers worked in oak, a wood unfavourable to the tool, but which, in thoir mafterly hands, admitted every flroke, and repaired the toil D O O 201 toil with immortality : we now ufe fir, the weakefl:, and pooreft of all woods that could have been employed for this purpofe ; and we can give for this but two reafons, equally mean ; ihefe are, that it comes cheap, and cuts eafy. It vvill not admit of thofe delicate ftrokes which have eternalized the chiffels of our fathers; norfupport itfelf, in thofe tender parts into which they cut their fine works. We have the fame materials in which they wrought, and not one kind, but many, of wood that will be very uleful for the purpofe. The pear-tree is famous, and the maple more ; this lafl: was known in theearliel!: time of which we have account, and celebrated for its excellence for this purpofe; what then is the reafon our people do not ufe them ? They cut as freely as deal, and they are not nearly fo liable to break off in pieces to the difcredit of the work. It is not needful the whole Doer cafe fhould be made of fuch wood ; no, not the whole columns ; let thofe who calculate expence fo nicely, fave in thefe articles, and only make the pieces of this wood that are for fculpture, the capital of a column, the crnaments of a freeze, or the like. The liifference of colour, to us who cover all with paint is nothing ; and the work would flaew in a finer manner, and would be much more lafting. One caution we fliall give the archltedl in this cafe, which is, that he caufe a careful and judicious painter to be employed where there is carved work ; for the niceil ftrokes of thechiffel will be loft if clumfily covered with paint. Two things are efiential to beconfidered in the painting of carved work ; the firft is, to ufe fuch a colour as fhall cover the work without clogging it, and the other is to lay it on in fuch a manner that it ftiall not need a Ipeedy retouching. There may eafily be contrived for this purpofe a paint of a thinner bcdy than ordinary, which will colour without loading ; ard we know how poor an appearance the beft piece of fculpture in wood makes when it has been two or three times painted. It is partly the badntfs of the work, and partly the deftrudlion of it by frequent colouring, which has put carving fo much as it is out of ufe at prelent. Indeed it is now threatened to he utterly turned out of doors ; and while the prcfefTors of the art fubmit to the comparilon, they fcarce deferve pity. The old deception of ftamp-paper, inftead of carved wood, is coming up with all the rage of fafliion ; and we have the mortification to fee his majefty's royal letters patent, lately granted to a gingerbread in-^ vention of this kind. Our fculptors need do no more to banifh this invocation, than to op- pofe their work well executed againft it; for there is no eye but will per- ceive the difference ; the cleannefs and (harpnefs which follows the chif- fcl can never be equalled by fuch contrivances, nor the ftucco, when a tolerable hand fafhions it. They are great in their defigns, and they ton- tent themfelves with. the pooreft execution of them. The judicious ar- cbiteft will tell them, that the plaineft moderate-fized room, finished in a F f f work- 202 D O O workmanlike manner, Is p-eferable to the largeO: defaced by thefe poor ornaments ; and that it is better to have a Doric Door-cafw-of wood, than a Co'i-nhian or Comnofite of paper. Vv'e have now conlidered the ornaments ; \vs h.n'e explained to the ftu- dent what he is to undert.ikc, and in what manner to execute the great concern of the decoration of Door-cafes, whether in the plain and com- mon manner, or, with the higheft grace the fcience aftbrds for them, the orders of arciiitedlure. V/e have conlidered alfo the opening, and its di- menfK)ns and form ; and all that remains is to treat of the Door itfelf, which is to clofe that apertuie, and to occupy the center of the propofed decoration. The Door imift be of due thicknefs to prevent its warping, and that muft be farther fecured alTo by its being made of fealoned tim- ber, and framed in panntls. With refpeft to the kind of timber, not- withfianding the great variety our own country affords, that is reduced in a manner to two, oak and fir; againft the firfl: nothing can be objected, for it has both ftrength and beauty; but the other is inferior to many kinds of our own growth. 1 he oak or wainfcot Doors are appropriated to the better kind ol buildings, and are intended to fliew their true fur- Jace and their natural colour. Thefe are often wrought with a great deal of beauty, and are an ornament in themfelves, exclufive of the decora- tions. The fir or deal Djors are meant to be painted. They are moif common in houfes of Ic-alT: expence ; and when they get into better edifi- ces they are fo uel! framed and wrought, that they often make no bad appearance. The a Ivantage of thefe is their lightnefs ; thofe of wain- fcot, of the fame dimenfions and diameter, being much heavier. Jjelide the wainlcot, we fee in fome places infide Doors of great elegance and expence, wrought of mahogany, or inlaid with rofe-wood, and decorated with Iculpture. Either of thefe kinds are very elegant; and thole who have been lamiliar with them, will not approve a painted Door in an elegant apartment. 'l"he opening of the Door is next to fall under confideration, and the common architert will think, that he has no more choice than to place the hinges on ont or the otlier fide, fo that it may open one way or the other, inwards or outwards : for one of tliek two ways he will luppole every Door in the wor^d muit open. But the:e is a way different from cither of thefe, and it is a method of extreme elegance. A llreet Door opening inwards is of no inconvenience, bccaufe it opens into a hall, which is a room of no conlcquencc ; but this i-. not the cafe i:i the more elegant apartments, where the communication is by a Dcor in the par- tition wall, and the entrance immediately out of one room into another. We Will fuppole the two principal rooms upon a firif fioor, communi- cate by a Door in the center of the partition. In an evening when they are lighted up, this Door is thrown open, and the furniture in both being alike DOR. 203 alike, it becomes ns one apartment. In this cafe the Door, according to the modern cullom, muft open into one or into the other of the rooms, and into which foever of the two it is, it will there be a bkmifli ; an awkward flanting piece, ftanding in the room with a difagreeable {harp an- gle. This may be prevented by making a cavity fomewhat more than equal to the depth and fubftaiice of the Door in the thicknefs of the wall. Into this the Door may Aide by a gentle touch, and remain undifcovered ; and a handfome brafs ring being fixed to the edge, it may come out again when it is to be fhut with as flight a motion. This is done at the houfi of a gentleman near Hanover-fquare, and the manner of it there may ferve as an example to other builders. The opening, in the ufual way, is either by the whole Door on one fide, or by half of it each way, the Door being compofed cf two, folding in the middle; but in either ca(e it is not comparable to the method we have here propofed of Aiding it into the wall on many occafions. Lart of all we come to the ftrudure of the fabric of the Door itfelf : this fliould be contrived for ftrength, beauty, and flraitncfs. All thefe purpofes are anfwered by making it in many pannels. The folding, or half Doors, are beft made of four pannels, tv.'o larger and two fniallcr; and the entire Door of eight. The framing muft be found, and the joints well fecured. They may be varied in form many ways : but to be mi- nute in thefe things (liews a poornefs of genius in the architect. The befl form of the pannels is the plaineft, and this is a long fquare ; the two or four larger fliould be long upwards, and the other crofs-wile. This is a conftruftion that fhews llrength and firmnefs, and tliis is all that Hiould beconfulted here, the decoration belonging to the other parts. Doric, is the name of one of the live orders in architedure, it is one of the thiee antient orders of the Greeks. It is ufually placed upon the attic bafe ; (he whole height is feven and an half or eight diameters; and its capital is p!ain, being fortJied only of mouldings ; in the entabla- ture the freeze is enriched with figures called triglyphs, to be explained under that head ; tlie fpaces between thefe are called metopes, and may be either left plain or decorated; and its cornice has drops. The Doric is t!.e oldeft of all the orders ; and originally had no bale; it is the moil: natural and befl proportioned of them all. The firft building in which this order was uled was a temple at Argos, built to Juno, by Dorus, a king Achaia, from whom the order was afterwards named. It b.as been much enriched and embellillied fmce its invention, fo what is called Tufcan, comes in many things nearer the ancient Djric, than the order called by that name at this time. The ancient Doric is iccn in great plainneis in the remains of the Parthenian at Athens, and in the theatre of Marcellus at Rome. It is ufed at this time principally in ifrong build- ings, gates, citadels, the lower part of churches, and the like, ia which places 204 D R A places ftrength is more proper than elegance. The gate of Burlington- honfe, in Piccadilly, is of the Doric order. The triglyphs are fuppofed to be infeparablc from this order; but we find them frequently omitted for the fake of cheapnefs in ordinary works ; and there may be a reafori fometimes for leaving them out, and making the freeze plain even in the moft finifhed and elegant buildings. Vignola adjulls the proportions of the Doric as follows : he divides the whole height cf the order, with- out the pedellal, into twenty parts, or modules; one of which he al- lows to the bafe, fourteen to the fhaft or fuft, one to the capital, and fojrto the entablature. The particular proportions of the feveral parts and members may be feen under their refpedive articles. Dormer, in architedture, is the window made in the roof of a houfe, or above the entablature, being raifed upon the rafters. Dormant-Tree, is a name given by workmen to a great beam lying crofs a houfe, commonly called a fummer. Dormitory, a gallery in convents or religious houfes, divided into- cells, in which the religious flcep. Doucine, in architedlure, is a moulding or ornament on the higheft part of the cornice, in the form of a wave, half convex, and half con- cave. The Doucine is the fame as a cymatium, or gula. DovE-TAiL ING, in Carpentry, is a manner of fallening boards toge- ther, by letting one piece into another, in form of the tail of a dove. It is the flrongefl: of the kinds of jointings or aflemblages, wherein the tenon, or piece of wood which is put into the other, goes widening to the extreme ; fo that it cannot be drawn out again by reafon the extreme or tip is bigger than the hole. It is called by the French, Queue de A-- ron, i. e. Swallow-tail, which name is alfo ufed by the Englilh them- lelves in fortification. Drag, a door is faid to drag when in opening or fhutting, it hangs or grates upon the floor, or cell. Dragon Beams, are two ftrong braces or flruts which ftand under a breft-fummer, meeting in an angle upon the flioulder of the king-piece. Draper Yj in fculpture and painting, the reprefentation of the cloath- ingof human figures, and alfo hangings, tapeftry, curtains that are not carnations or landfcapes. The art of Drapery confifts, i. In the order of the folds or plaits, which ought to be fo managed, that you may cafily perceive what it is they cover, and dillinguifti it from any thing elfe. Again, the folds ought to be large, as breaking and dividing the fight the lefs ; and there fhould be a contraft between them, otherwife the Drapery will be ftiff. 2. In the quality of the fluffs, for fome make their folds abrupt and harfh, others more foft and eafy ; the furface of fome have a lulf rr, others are flat and dead j fome are fine and tranfparent, others firm and folid, 3. In the variety of colours, which, when well managed, makes D Y P 205 makes the greatefl beauty of painting, all not being equally amicable and friendly with refpedl to each other, and feme never to be placed near cer- tain others. M. De Piles obferves, that Drapery muft never be made to adhere to the parts of the body ; that a great motion and lightnefs of the . Drapery are only proper in figures in great agitation, or expofed to the wind ; and that the nudities of the figures Ihould always be defigned before the painter proceeds to the Draperies. Draught, or Draft, in architefture, the figure of an intended building defcribed .on paper, in which is laid down by fcale, the feveral divilions and partitions of the apartments, rooms, doors, pafTages, &c. in their due proportion to the whole building. It is cuflomary, and con- venient, for any perfon, before he begins to eredl a building, to have De- figns or Draughts drawn upon paper or vellum, wherein the ichnography or ground-plot of every floor or flory is delineated ; as alfo the form or fafhion of each front, with the windows, doors, ornaments, in an ortho- graphy, or upright. Sometimes the feveral fronts, 6cc. are taken and re- prefented in the fame Draught, to lliew the effed: of the whole building, which is called fcenography or perfpeftive. Draught-Compasses, fuch as have moveable points to draw fine Draughts in architedlure. Draw-Bridge, a Bridge made after the manner of a floor, to draw up or let down, as occafion ferves, before the gate of a town or caftle. In navigable rivers it is fometimes neceflary to make the middle arch of bridges with two moveable platforms, to be raifed occafionally, in order to let the malls and rigging of veflels pafs through. Drip, in architedlure, are a certain kind of flep, made on fiat roofs to walk upon ; a way of building much ufed in Italy, where the roof is not made quite dat, but a Httle raifed in the middle, with Drips or fleps, lying a little to the horizon. Drops, in architedlure, an ornament in the Doric entablature, repre- fenting Drops, or little bells, immediately under the triglyphs. Dye, in architedlure, any fquare body, as the trunk, or notched part of a pedeftal ; or it is the middle of the pedeflal, or that part included between the bafe and the corniche, fo called becaufe it is often made in the form of a cube or Dye. Dye is alfo ufed for a cube of flone, placed under the feet of a flatute, and over its pedeftal, to raife it, and fliew it the more. Dyptere, in the ancient architedlure, was a kind of temple, encom- pafTed with a double row of columns ; and the Pfeudo Dyptere, or falfe Dyptere, was the fame, only that this was encompaffed with a fingle j-ow of columns, infleadofadouble row. Ggg Eagle' 2o6 E L B E. Eagle, in architedure, a figure of that bird, anciently ufed as an attribute or cognizance of Jupiter, in the capitals and friezes of the co- lumns of temples confecrated to that God. Eaves, in architefture, the margin or edgfe of the roof of an houfe, being the loweft tiles,, flates, &c. that hang over the v/alls, to throw off Vi'ater to adiftance from the wall. Eaves Lath, a thick feather-edged board, generally nailed round the Eaves ofa houfe for the lowermoft tiles, flates, or fliingles, to reft on. Echinus, is a term ufed fometimes to exprefs the ovolo, or quarter- round, and fometimes for a part of the figures with which that mem- ber is ufually carved. This laft is the more proper and ftrift fenfe, and in the fame manner ovolo, though ufually employed as the name of the whole member, is more ilridlly expreffive only of a part of its carving. The quarter round is ufually carved with what are called eggs and an- chors ; the eggs are the part from which this has been called ovolo, oviiniy being latin for an egg ; thefe eggs have a kind of fhell about them, be- fide their own, at a diftance from their furface, and feparating them from the anchors between ; this is called the Echinus, Echinus being the name of the hulk or Ihell ofa chefnut, which it was meant to refemble. Echi- nus therefore is properly the name of the fhell in the carving of the ovolo, or quarter-round, and it is improperly ufed for that whole member. Echo, in architefture, is a term applied to certain kinds of vaults and arches, generally elliptical parabolical figures, eredted to produce artifi- cial Echoes. Blanc, in his Echometry, at the end of his firft book of the fphere, teaches the method of making an artificial Echo. Vitruvius relates, that in divers parts of Greece and Italy, there were brazen vefTels artfully ranged under the feats of the theatres, to render the found of the voices of the aftors more clear, and make a kind of Echo ; by which means the whole audience might hear with eafe and pleafure. In Echoes, the place where the fpeaker ftands, is called the Centrum Phonicum, and the objed: or place which returns the voice. Centrum Phonicampticum. At the fepulchre of Metella, wife of CralTus, was an Echo which re- peated what a man laid five times. And authors mention a tower at Cyricus, where the Echo was repeated feven times. Egg, in architedlure, an ornament in that form, cut in the echinus or quarter- round of Ionic and Compofite capitals. The profile of an echinus is enriched with Eggs and anchors placed alternately. Elbow, in architedlure, an obtufe angle of a wall, building, road, &c. which divides it from its right line. 4 Ele- E N G 207 Elevation, in archite<5lure, the fame with an orthographic, or up- right draught of a building. Elliptical-arch, a part or fegment of the curve of an ellipfis. Elliptical-arches are frequently preferred to thofe that are circular in va- rious kinds of buildings, becaufe their fpan may be equal to thofe of the circle, without rifing to fo great a height j therefore they have been pre- ferred in bridges ; but it mud be remembered that they will decreafe in ftrength in proportion as they deviate from the circle. Elm, is of Angular ufe, where it may lye continually wet or dry in extremes, therefore proper for water-works, mills, ladles, and foles of wheel pipes, aquedudls, pales, fliip planks, beneath the water line. Some of it found in bogs has turned like the moft poliflied and hardeft ebony. It is alfo of ufe for wheel-wrights, handles for fmgle faws, the knotty parts for naves and hubbs ; the ilreight and fmooth for axel-trees ; and the very roots for curious dappled works, kerves of coppers, feather- edge and weather-boards, trunks, coffins, and Ihuffle-board tables. The tenor of the grain makes it alfo fit for all kinds of carved work, and moft ornaments belonging to architedlure. Vitruvius recommends it for te- nons and mortoifes. Embossing or Imbossing, in architecture, fculpture, &c. is form- ing, or fafliioning of works in relievo, whether cut with a chilTel, or otherwife ; it is a kind of fculpture or engraving, wherein the figures project out from the plane whereon they are engraven, and according as they are more or lefs protuberant. It is called by the Italians balfo, mez- zo, or alto relievo, and by the Englifli bafs relief, mean relief, or high relief. Embrasure, in architedure, the inlargement made of the aperture of a door or window on the infide of the wall, its ufe being to give the greater play for the opening of the door, or cafement, or tc admit the more light. When the wall is very thick, they fometimes make Em- brafures on the outfide. Empasting, in painting, is the laying on colours thick and bold, or applying feveral lays of colours, to the end that they may appear thick. Encarpus, a term by which fome have called the reprefentation of a feftoon, on friezes, and otherwife, as an ornament in buildings ; Vitruvius calls it by this name. Thefe feftoons were compofed of fruits, flowers and leaves, and Encarpus exprelles them befl when compofed of fruits, naoTTog being Greek for fruit. Engine, in mechanics, a compound machine, made of one or more mechanical powers, as levers, pullies, fcrews, &c. to raife, to projeft, or fnftain any weight, or produce any eifedl which could not be eafily effedled otherwife. Engines are extremely numerous ; fome ufed in war, as the battering ram, balifta, waggons, chariots, &c. others in trade and manu- 2o8 E P I manufadlures, as cranes, mills, prefles, &c. others to meafure time, as clocks, watches, &c. and others for the illuflration of fome branch of fcience, as the orrery, commentarium, and the like. In general we may obferve, concerning engines, that they conlifl of one, two or more of the fmiple powers varioufly combined together ; that in moft of them the axis in peritrochio, the leaver and the fcrew, are the conftituent parts j that in all a certain power is applied to produce an effed: of much greater moment; and that the greatefl effecfl, or perfedlion, is when it is fet to work with four ninths of that charge, which is equivalent to the power, or will but juft keep the machine in equilibrio. In all machines, the power will juft fuftain the weight, when they are in the inverfe ratio of their diftances from the center of motion. Entablature, in archite-dture, the ornament fupported by the ca- pital on the top of a column or pilafler. Every column conlifts of its bafe, fhaft and capital, and fupports an Entablature ; thefe together con- iiitute the entire body, or order ; and the Entablature, like the capital, xliffers in every order. The Entablature confifts of three parts, the ar- chitrave, frieze, and cornice ; the architrave is compofed of one or more faces, and refts upon the capital ; the frieze comes next, and is the middle part of the Entablature, the cornice is the top, or uppermoft. In the Tufcan order the Entablature, is plain ; in the Doric the frieze is decorated with triglyphs, or channelled figures ; in the Ionic or other richer orders, the cornice is decorated with den tells, modillions, and a variety of ornaments. The Entablature, according to Palladio, fhould be a fifth of the height of the column, and this equally in all the or- ders, except the Tufcan, in which it is a fourth. It is different in different orders : for notwithftanding it confiits of the three before- mentioned divifions in all j yet thefe parts are made up of more or fewer particular members or fubdivifions, according as the order is more or lefs rich. Vignola makes the Entablature a quarter of the height of the whole column in all the orders. In the Tufcan and Doric, the architrave, frieze, and cornice, are all the fame height. In the Ionic, Corinthian, and Compofite, the whole Entablature being of fif- teen parts, five of thefe go to the architrave, four to the frieze, and fix to the cornice. Entersole, in architedlure, a kind of little flory, fometimes called a mezanzine, contrived occafionally at the top of the firfi: flory, for the conveniency of a wardrobe, &c. Entry, a Door, Gate, PafTage, &c. through which we arrive at any place. Epistyle, in the ancient architedlure, a term ufed by the Greeks, for what we call architrave, viz. a malfive piece of ftone or wood laid im- mediately over the capital of a column. Eurithmy, EXP 209 EuRiTHMV, in archltedure, fculpture, and painting, is a certain ma- jefty, elegance, and eafinefs, appearing in the compolition of divers mem- bers or parts of a body, painting or fculpture, and refulting from the fine proportion of it. Vitruvius ranks the Eurithmia among the effential parts of architeiSure. He defcribes it as confifting in the beauty of the con- ftrudlion, or afiemblage of the feveral parts of the work, which render its afpedt, or its whole appearance graceful; i. e. when the height cor- refponds to the breadth, and the breadth to the length, &c. From thefe three idea?, or defigns, orthography, fcenography, and profile, it is, that the fame Eurithmia, majeftic and beautiful appearance of an edifice, does refult, which creates that agreeable harmony between the feveral dimen- lions, i. e, between the length, breadth, and height of each room in a fa- bric, fo that nothing fl-ems difproportional, too long for this, or loo broad for that, but correfponds in a juft and regular fymmetry and confent of all the parts v/ith the whole. EusTYLE, a term by which the ancients exprefled the beft and moft elegant manner of placing columns, with refpedt to diftance, or interco- lumniation. Vitruvius fays the Euftyle intercolumniation, or bed diftance of placing columns, is that of four femi-diameters and a half, that is two diameters and a quarter of the column. He iays this manner of placing columns exceeds all others in ftrength and convenience, as well as beauty. Exaggeration, in painting, is a method of reprefenting things wherein they art charged to much, or marked too flrong, either in ref- pe(fl to the defign' or colouring. ExEDR^, in antiquity, a general name for fuch buildings as were dif- tindt from the main body of the churches, and yet within the limits of ithe church, taken in 'its largell fenfe. Expression, in painting, the reprefentation according to its natural charadler, and the painter's invention, or plan. In portraits it muil be ken whether the perfon is grave, gay, a man of bufinefs or wit, plain, gentle, &c. each charadler muft have an attitude, the ornaments, and back-ground proper to it ; and all about it muil be expreffive of the man, and have a refemblance as well as the features of the face. If the perfon has any particularities as to the pofition of the head, eyes, or mouth, if not unbecoming, they muft be ftrongly expreffed. There are a fort of moving features, and are as much a part of the man as the fixed ones : fome things raife a low fubjedt, and contribute more to a furprizing like- nefs than any thing elfe. If there be any thing particular in the hiftory of the perfon which is proper to be exprefled, it is a great improvement to the portrait, to them that know that circumftance. Robes, or other marks of dignity, or of a profeflion, employment, or amufement, a book, a fhip, a favourite dog, or the like, are hiftorical expreflions, common in portraits. There are feveral kinds of artificial expreflions pradtifed by H h h painters, 210 EYE painters, bccaufe of the difadvantage of their art in that particular, in comparifon of words. But there is no better fchool than nature for expref- fion. A painter therefore (hould, on all occafions, obferve how men look and adV, when pleafed, grieved, angry, &c.* Love is expreffed by a clear, fair, and pleaf\nt countenance, without clouds, wrinkles, or unpleafant bendings, giving the forehead an ample height and breadth, with a majeftic grace ; a full eye, with a fine iLadow at the bottom of the eye-lid, and a little at the corner; a proportionable iiole J noflrils not too wide j a clear cheek, made by ihadowing it on one lide, and a fmihng mouth, made by a thin upper lip, and fliadovving the niouth-line at the corners. Fear is exprefled by making the eyes look hol- low, heavy and downwards, thin fallen cheeks, a clofe mouth, carelefs flaring hair about the ears. Envy is bell: expreffed by only the hanging of the cheeks and a pale countenance, and fometimes by grinding of the teeth. Let every pailion be reprefented according to its outward appearance in thofe in whom it reigns. If you aim at any excellence in this art, you mufl endeavour to choofe out the befl adlions for every purpofe, in reflraining the luxurious fancy of nature by a deliberate difcretion, by the benefit of which you will fur- nifli your defign, always exprefilng in each member a certain hidden re- femblance of the principal motions which afte(5l the eye and foul of the fpeftator. To exprefs a paffion truly, you ought to give every thing its proper motion, or that which heft fuits your intention, which is nothing elfe but the agreement of proportion with the adlion or paffion intended, wherein confifts the whole life of the art, for hereby an evident difference is made between the living and the dead ; the fierce and the gentle ; the wife and the finiple ; the fad and the merry ; and in a word, difcovers all the feveral paffions and geftures which the body of a man is capable of. But before thefe things can be exactly done in a pidine, you muff firft intenfely confider the life, that you may come as near it as poffible, to which adding art, you will meet with no motions fb potent, which you will not be able artificially to imitate. Thefe things will be the more ex- adlly accompliflied, by viewing and continually pra(ftifing what we have feen ; fo as lively to exprefs all geffures, aftions, and paflions, incident to natural bodies. Eye, in architeflure, is applied to any round window made in a pedi- ment, an attic, the reins of a vault, or the like. Eye of a dome, an aperture at the top of the dome, as that of the pantheon at Rome, or of St. Paul's at London ; it is commonly covered with a lantern. Eye of the volute, in architedure, the center of the volute, or that point in which the helix or fpiral, of which it is formed, commences. Eye-brow, in architefture, is ufed in the fame fenfe as lift or fillet, 4 Fabric, F E L 211 F. Fabric, the ftru6ture or conftrudtion of any thing, particularly a building, as a houfe, hall, church, &c. Facade, or Face, in architedure, the front of a building, or the fide which contains the chief entrance. It is alfo fometimes ufed for the fide which it prefents to the ftreet, garden, court, 6cc. and fometimes for any fide oppofite to the eye. Fascia, is a term ufed to exprefs a flat member in the entablatures- of columns or elfewhere, refembling a band or broad fillet. Our work- men call it zface or facio, and it is fometimes written facia. The ar- chitrave, in the more elegant orders, is compofed of three parts, or di- vided into three bands over one another ; thefc are called the Jafcice of the architrave : the Tufcan fliould have properly one fafcia, nor had the Doric originally any more. But the architeds have taken the liberty of deviating from exadnefs in this, as in many other refpe<£ts. Fafcias, in brick buildings, certain juttings out of the bricks over the windows of each ftory, except the upper one. Thefe are fometimes plain, like thofe of columns ; but fometimes they are moulded ; and the moulding is ufually a fcima reverfa at the bottom, above which are two plain courfes of bricks, then an aflragal, and laflly a boultin. It is the fame in ftone buildings as it is in brick, and they are alfo fometimes plain, and fome- times moulded with a fcima reverfa, or ogee. Felling of timbej-. Many circumflances are well known and con- ftantly obferved in the Felling of timber for building, which, though to a hafty obferver they may appear trifling, yet prove, on experience, to be of the utmoft confequence. One thing obferved by M. de Buffbn, which greatly increafes the folidity and ftrength of timber, is, that the trees in- tended to be felled for fervice fliould be firft flripped round of their bark, and fuffered fo to fland and die upon the fpot before cutting. The lappy part, or blea of the oak, becomes by this means as hard and firm as the heart, and real ftrength and denfity of the wood has been proved, by many experiments, to be greatly increafed by it, nor is this a practice of any de- triment to the proprietor, fince the remaining flumps of thefe trees fend up their young fhoots as vigoroufly as if they had been cut down in their natural condition. When any tree is to be cut down for timber, the firft thing to be taken care of is a fkilful difbranching fuch limbs as may endanger it in its fall ; many trees are utterly fpoiled for want of a pre- vious care of this kind. In arms of timber that are very neat, it is al- ways neceflary to chop or fmk in them clofe to the bole, and then, meet- ing 212 FEN ing It with downright ftrokes, it will be fevered from the tree without fplitting. In felling the tree, take care always to cut as clofe to the ground as poffible, unlefs it is intended to be grubbed up j and the doing this is of advantage both to the timber and the wood ; for timber is never fo much valued, if it be known to grow out of old flocks. A more en- larged account will be given under the article timber. Fence, a hedge, wall, ditch, bank, or other enclofure, made round gardens, fields, woods, &c. In hotter climates than England, where they have not occafion for walls to ripen their fruit, their gardens lie open, where they can have a water-fence, and profpedts ; or elfe they bound their gardens with groves, in which are fountains, walks, &c. which are much more pleafing to the fight than a dead wall ; but in colder coun- tries, and in England, we are obliged to have walls to fhelter and ripen our fruit, although they take away much from the pleafant profpedl of the garden. Since therefore we are under the neceflity to have walls to fecure our gardens from the injuries of winds, as well as for the conve- nience of partitions or enclofures, and alfo to ripen our fruit, brick walls are accounted the beft and warmeft for fruit ; and thefe walls, being built panel wife, with pillars at equal diftances, will fave a great deal of charge, in that the walls may be built thinner than if they were built plain, without thefe panels ; for then it would be necefiary to build them thicker every where ; and, befides, the panels make the walls look the handfomer. Stone walls are to be preferred to thofe of brick, efpecially thofe of fquare hewn fi:ones. Thofe that are made of rough fi:ones, though they are very dry and warm, yet, by reafon of their unevennefs, are inconvenient to nail up trees to, except pieces of timber be laid in them here and there for that purpofe. But in large gardens it is better to have the prof- ped: open to the pleafure-garden, which fhould be furrounded with a fofie, that from the garden the adjacent country may be viewed ; but this muft de- pend on the fituation of the place ; for, if the profped from the garden is not good, it had better be fhut out from the fight by a wall or any other Fence, than to be open. As alfo, when a garden lies near a popu- lous town, and the adjoining grounds are open to the inhabitants ; if the garden is open there will be no walking there in good weather, with- out being expofed to the views of all pafi"engers, which is very difagreea- ble. Where the fofies are made round a garden which is fituated in a park, they are extremely proper ; becaufe hereby the profpedls of the park will be obtained in the garden, which renders thofe gardens much more agreeable than thofe which are confined. In fuch places were there are no good profpedls to be obtained from a garden, it is common to make the enclofure of park paling, which, if well performed, will lail many years, and has a much better appearance than F I L 213 than a wall ; and this pale may be hid from the fight within by planta- tions of flirubs and e\ er-greens ; or there may be a quick hedge planted within the pale, which may be trained up, fo as to be an excellent Fence by the time the pales begin to decay. There are fome perfons who make ftuckade Fences round their gardens to keep out cattle, &c. which, when well made, will anfwer the purpofe of Fences ; but this being very expenfive in the making, and not of very long duration, has occafioned their not being more commonly in ufe. As to Fences round parks, they are generally of paleing ; which, if well made of winter-fallen oak, will laft many years. The Fence may be lix feet and a half high, which is enough for a fallow deer ; but, where there are red deer, the Fence fliould be one foot higher, otherwife they will leap over. Some inclofe their parks with brick walls ; and in coun- tries where ftone is cheap, the walls are built with this material ; fome with, and others without mortar. The height of garden-walls fhould be twelve feet, which is a moderate proportion, and, if the foil be good, it may in time be well furnillied with bearing wood in every part, efpe- cially with that part planted with pears, notwithftanding the branches being trained horizontally from the bottom of the walls. Festoon, an ornament of carved work, reprefenting a wreath, or garland of flowers or leaves, or both together, twifted or interwoven one with another ; the Feftoon is naturally thickeft in the middle, fmall at each end, and tied up there, whence a part commonly hangs down be- yond the knot. The ancient ufe of the Feftoon was to hang upon the gates of temples at feftivals, and it confifled of flowers, or fruits, and their leaves only j but we have, of later time, deviated fo far from truth and nature, that we have twifled inftruments of mufic, war, and em- blems of the arts and profeflions of all kinds into this form. The an- cients would have exclaimed at a garland of drums and iiddles, or a wreath of cannons and battle-axes, but we overlook thefe abfurdities. The Avord is French, but it is derived from the Latin feflum, feaft or feftivity. Feftoons are hung upon arches, and in the freeze of entablatures, fome times alfo about vafes, and other ornaments. Figure, in architedlure, fignifies the reprefentations of things made- in fclid matter, as ftatues. Sec. In painting and defigning, it is the lines and colours that form the reprefentation of a man, or other animal. Fillet, in architedlure, a little fquare member or moulding, ufed in divers places and on divers occafions ; but generally as a crowning over a greater moulding. It is called lifta or liftella by the Italians ; by the French reglet, and by others band and bandelette. In painting, gild- ing, &c. it is a little rule, or reglet of leaf-gold drawn over fome mould- ings, or on the edges of frames, pannels, Sec. efpecially when painted white by way of enrichment. lii Finishing, 214 FLO Finishing, with aichited:s, is frequently ufed of a crowning, acro- ter, &c. raifed over a piece of building, to terminate and finifh, or com- pleat it. Fire-Stone, a fort of itone called alfo Rygate flone, of the name of the place from whence it is chiefly brought, being very good for fire-hearthsK ovens, ftoves, &c. Flemish Bricks, a neat, flrong, yellow kind of bricks, brought from Flanders, and commonly ufed in paving yards, flables, 6cc. being preferable for fuch purpofes to the common bricks. Thefe bricks are fix inches and a quarter in length, two and a half in breadth, and one and a quarter thick. Now allowing one fourth of an inch for the joint, feventy- two of them will pave a yard fquare ; but if they be fet edgeways, then a yard fquare will require one hundred. Floor, in architefture, is the under fide of the room, or that pars whereon we walk. Floors are of feveral forts, fome of earth, fome of brick, fome of ftone, and fome of wood. Carpenters by the word Floor» underftand as well the framed work of timber, as the boarding over it. Earthen Flooi-s are commonly made of loam, and fometimes (for Floors' to make malt on) of lime and brook fand* and gun-duft, or anvil-dufls from the forge. Flooring, a rural fort of work, by which, in this place, are not meant floors laid with boards or planks, but fuch as are ufed in plain country habitations, and the manner of making them. Take two thirds of lime, and one of coal-aflies well fifted, with a fmall quantity of loamy clay j mix the whole that you intend to ufe together, and temper it well with water, making it up into a heap, let it lie a week or ten days, in which time it will mellow and digeft ; then tem- per it well over again, and be fure that your quantity of water does not exceed, but rather that it may obtain a mellow foftnefs and toughnefs froni' labour : then heap it up again for three or four days,, and repeat the tem- pering very high, till it becomes fmooth and yielding, tough and glewy. Then the ground being levelled, lay your floor therewith about two and a half, or three inches thick, making it fmooth with a trowel : the hotter the feafon is, the better ; and when it is thoroughly dried, it will conti- nue time out of mind. This makes the beft floors for houfes, elpecially for malt houfes ; but as for thofe who cannot get thefe materials, or ga to the charge of them, they may make of clayey loam and new foft horie- dung one third, with a fmall quantity of coal aihes, if they can be had, and temper theft; after the afore-mentioned manner, and lay the floor with the duff, three or four inches thick, fmooth and even, which will, cement, become hard, ftrong, and durable, being done in a hot and dry feafon, good for cottages, barns, and other fmall houfeSo 4 But, FLO 215 But if any would" have more beautiful floors than thefe, they muft lay their floors even, fniooth, and fine, either with the firft or lafl men- tioned Flooring ; then take lime made of rag flones, and temper it with a little whites of eggs, the more eggs the better, to a very high pitch, with which cover your floor about a quarter or half an inch thick, before the under Flooring be too dry, that they may well incorporate together ; this being well done, and thoroughly dry, if fometimes rubbed over with mops or cloths, with a little oil thereon, it will look very beautiful and tranfparent, as if it were pohlhed metal or glafs, provided the eggs and lime were thoroughly tempered, and otherwife well performed. Sir Hugh Plat gives a receipt for making an artificial compofition wherewith to make fmooth, glittefing, and hard floors, and which may alfo ferve for plaiftering of walls. Ox blood and fine clay. tempered toge- ther, he fays, makes the fineft floor in the world ; and that this mix- ture, laid in any floor or wall, will become a very flrong and binding liibllance. Concerning boarded floors, it is to be obferved, that the carpenttrs never floor their rooms with boards, till the carcafe of the houfe is fet up, and alfo is enclofed with walls, left: the weather fhould wrong the Flooring ; yet they generally rough plane the boards for Flooring, be- fore they begin any thing elfe about the building, that they may fet them by to fciibn, vs'hich is done as follows ; they lean them one by one on end-end aflant, with the edge of the board againfl; a balk fomewhat higher than half the length of the board, and then they fet up another board in the fune pofture on the other fide of the balk, fo that the boards crofs one another, above the balk ; then on the firft: fide they fet another board in the fame poft:ure, and on the fecond fide another, and fo proceed- ing alternately, till the whole number of boards is thus fet on end. The boards being fet up in this pofture, there is left a fpace of the thick- nefs of a board all the length of the boards, but juft: where they crofs one another, for the air to pafs through to dry and Ihrink them ; but they are fet under fome covered fhed, that neither the rain nor fun may come at them ; for if they fhould be wetted with rain, that would fwell. them inft:ead of ihrinking them ; and if the fim ftiould fliine very hot upon them, it would dry them fo faft, that they will fplit or crack, which, is what they call tearing or fliaking. There is another way of drying and feafoning boards for. floors, viz. by laying them fiat upon three or four balks, each board about the breadth of a board afunder, the whole length of the balks ; then they lay another lay of boards athwart the laft, and fo till they have laid them all after this manner -, fo that iii this pofition they alfo lie hollow, for the air to play between them. Of 2i6 F O O Of meafuring floors : boarded floors are ufually meafured by the fqnare (of one hundred fuperficial feet) by muhiplying the length of the room in feet by the breadth in feet, and the producft is the content in feet ; then the chimney- ways and well-holes for flairs are meafured by them- ftlves, and their content in feet is deduded from the whole content ; and afterwards cut off two figures from the remainder on the right hand, and what remains on the left hand is fquares, and what are cut off are odd feet of the content of the Flooring in that room. Flutings, in architefture, are hollows or channellings, which are carried perpendicularly up columns by way of ornament. They are cut lengthwife all round the Oiaft of the column, and are ufually round- ed at the ends. Vi'truvius fays, they were firlf intended to reprefsnt the folding of a garment. The Flutings of columns properly differ ac- cording to the feveral orders : in the Doric they fhould be twenty to each column ; in the Ionic twenty-four, and Co on ; but the prefent ar- chitects do not very ftridtly adhere to thefe rules. The Flutings of co- lumns are fometimes left open, and fometimes there is carried up a rounded body Hke a rope, plain or twilled all along their middle. They are, in this condition, faid by fome to be cabled, and the columns are called cable-fluted columns. Between the flutes are little fpaces that feparate them, which Vitruvius calls flria, and we lills : though, in the Doric, the flutes are frequently made to join one another, without any intermediate I'pace at all ; the lift being Iharpened off to a thin edge, which forms a part of each flute. Sometimes the Flutings are made flat, and a.^-e called facettes j but thefe have never fuch a good efl^edt as the others. Vitruvius fays, that when there are Flutings in the column, there ought alfo to be eggs and anchors in the quarter-round of the ca- pital, and even pearls and olives, in a baguette, to be made underneath, inftead of annulets. Thefe eggs and olives ought to be made of the fame number with the Flutings, and to be regularly diftributed. Flyers, in architedlure, fuch ftairs as go ftraight, and do not wind round ; nor have the fteps made tapering, but the fore and back part of each flair, and the ends, refpecftively, parallel to one another ; lb that if one flight do not carry you to your intended height, there is a broad half fpace, from whence you begin to fly again, witli fteps every where of the fame length and breadth as before. Foliage, a clufter or afl"emblage of flowers, leaves, branches, &c. Foliage is particularly ufed for the reprefentations of fuch flowers, leaves, branches, rinds, &c. whether natural or artificial, ufed as enrichments on capitals, freezes, pediments, &c. F ot-Pace, or Half-Pace, is apart of a pair of ftairs, whereon, after four or fix fteps, you arrive at a broad place, where you may take two F O U 217 two or three paces before you afcend another flep, by that means to eafe the legs in afcending the reft of the fteps. Forge, a httle furnace, wherein fmiths, and other artificers of iron or flcel, &c. heat their metals red hot, in order to foften and render them more malleable and manageable on the anvil. Forge is alfo ufed for a large furnace, wherein iron ore, taken out of the mine, is melted down ; or it is more properly applied to another kind of furnace, and then cafl into fows and pigs, is heated and fufed over again, and beaten afterwards with large hammers, and thus rendered more foft, pui-e, duc- tile, and fit for ufe. Of thefe there are two kinds : the firfl is called the finery, where the pigs are worked into grofs iron, and prepared for the lecond, which is called the chafery, where it is further wrought into bars fit for ufe. Forging, in Imithery, tlie beating or hammering iron on the anvil, after having firff made it red hot in the forge, in order to extend it in various forms, and fafliion it into works. There are two ways of Forge- ing and hamniering iron ; one is by the force of the hand, in which there are ufually feveral perfons employed, one of them turning the iron and hammering likewiie, and the rell only hammering. The other way is by the force of a water-mill, which raifes and works feveral large hammers beyond the force of men, under the ftrokes of which the workmen prcfent large lumps, or pieces of iron, which are fuffained at one end by the anvils, and at the other with iron chains faflened to the cieling or the forge. This hft way of Forging is only ufed in the largeft works, as anchors for Ihips, 6cc. which ufually weigh fcverai tlioufand pounds. For lighter works, a lingle man ferves to hold, heat, and turn with one hand, while he hammers with the other. Foundation', in architeifture, is that part of a building which is under ground, or the mafs of flone, brick, &c. which fupports a building, or upon which the walls of a fuperrtrufture are raifed, or'it is the coffer or bed dug below the level of the ground, to raife a building upon ; in which fenfe, the foundation either goes to the whole area or extent of the building; as when there are to be vaults, cellars, or the like ; or it is drawn in cuts or trenches, as when only walls are to be raifed. Some- times the Foundation is maffive, and continued under the whole building, as in the antique arches and aqueducts, and fome amphitheatres ; but it is more ufually in fpaces or intervals, either to avoid expence, or becaufe the vacuities are at too great a diftance, in which latter cafe, they make ufe of i ululated pillars, bound together by arches. There are feveral things to be well confidered, in laying the founda- tion of a building, the moll material of which are here extraded from the beft archite^fts ancient and modern. That we may found our habita- K k k tion. 2i8 F O U tion firmly, requires the exadeft care ; for, fays Sir Henry Wooton, " if " the foundation dance, 'twill marr all the mirth in the houfe. There- fore, fays that excellent arcliited, we murt firil examine the bed of eartb upon which we are to build, and then the under fillings or fubftrudion as the ancients call it. For the former, we have a general precept in Vitruvius, twice repeated by him as a point indeed of main confequence ; SubJlruSiionis fundationes fodiantiir fequeajit inveniri adjolidum et mfoHdo. By which he recommends not only a diligent, but even jealous examina- tion what the foil will bear ; advifing us not to reft upon any appearing folidity, unlefs the whole mould through which we cut have likewife been folid. But he has no where determined how far we fhould go in this fearch, as perhaps depending more upon difcretion than regularity, ac- cording to the weight of the work. Palladio has ventured to reduce it to a rule ; and allows a fixth part of the height of the whole building for the hollowing or under-digging, unlefs there be cellars under-ground ; in which cafe he would have it fometimes lower. See Sir Henry Wooton's Elements of Architedure. Palladio alfo lays down feveral rules to know if the earth be firm enough for the foundation, by obfervations from the digging of wells, cifterns, and the like, and from herbs growing there, if there be fuch as ufually fpring up in firm ground ^ alfo if a great weight be thrown on the ground, it neither founds nor (hakes j or if a drum being fet on the ground, or lightly touched, it does not refound again, nor fhake the water in a veflel fet near it. Thefe, fiys he, are figns of firm ground. But the beft way to difcover the nature of the foil, is to try it with an iron crow, or with a borer, fuch as is ufed by well-diggers. Architeds ought to ufe the utmoft diligence in this point, for, of all the errors that may hap-- pen in building, thofe are the moft pernicious, which are committed in the foundation J becaufe they bring with them the ruin of the whole building ; nor can they be amended without very great difficulty. Foundations are either natural or artificial ; natural, as when we build on a rock, or very folid earth ; in which cafe, we need not feek for any turther ftrengthening : for thefe without digging, or other artificial helps, are of themfelves excellent foundations, and moft fit to uphold the great- eft buildings. But if the ground be fandy or marlhy, or have latel)^ been dug, in fuch cafe, recourfe muft be had to art. In the former cafe, the archited muft adjuft the depth of the foundation by the height, weight, &c. of the building ; a fixth part of the whole height is looked upon as a medium j and as to thicknefs, double that of the width of a wall is a good rule. If you build upon molTy and loofe earth, then yoa muft dig till you find found ground. This found ground, fit to uphold a building, is of divers kinds ; as Alberti well obferves, is in fome places fo hard, as fcarcely to be cut withiron, in other places very ftifi^, in other I pkices F O U 219 places blackifli, which is accounted the weakeft, in others like chalk, and in others Tandy ; but of all thefe, that is the bell that requires moft labour in cutting or digging, and when wet, does iiot diflblve into dirt. If the earth to be built on is very foft, as in raoorilh grounds, or fuch that the natural Foundation cannot be trufted, then you muft get good pieces of oak, whofe length muft be the breadth of the trench, or about two foot longer than the breadth of the wall ; thefe muft be laid acrofs the Foundation, about two feet afunder, and being well rammed down, lay long planks upon therh, which planks need not lie fo broad as the pieces are long ; but only about four inches of a fide wider than the ba- lls or foot of the wall is to be, and pinned or fpiked down to the pieced of oak on which they lie. But if the ground be fo very bad, that this will not do, then you muft provide good piles of oak of fuch a length as will reach the good ground, and whofe diameter muft be about one- twelfth part of their length. Thefe piles muft be forced or drove down with a commander, or a machine or engine for that purpofe, and muft be placed as clofe as one can ftand by another ; then lay planks upon thern, and fp'ikt or pin them down faft. But if the ground be faulty, only here and there a place, and the reft of the ground be good, you may turn arches over thefe loofe places, which will difcharge them of the weight. You muft not forget to place the piles not only under the outer walls, but aho under the inner walls that divide the building, for if thefe fbould fink, it would be the means to make the outer wall crack, and fo ruin the whole building. Having thus far confidered the bed of earth on which the building is to be eredled, we fliall next confider the fubftrudlion, as it was called by the ancients, but the moderns generally call it the Foundation. This is the ground work of the whole edifice, which muft fuftain the walls, and is a kind of artificial, as the other was natural ; as to which, thefe things that follow are moft neceflary to be obferved. i. That the bot- tom may be exadlly level; therefore lay a platform of good boards. 2. That the loweft edge or row be all of ftone, the broader the better, laid clofely without mortar, which is a general caution for all parts of a building that are contiguous to board or timber ; becaufe lime and wood are utter enemies to one another ; and if unfit confiners any where, then they are more efpecially fo in the Foundation. 3. That the breadth of the fubftruftion be at leaft double the breadth of the wall that is to be raifed upon it. But even in this cafe, art ought to give way to difcretion j and the fubftrudion may be made either broader or narrower, according as the goodnefs of the ground, and the ponderofity of the edifice re- quires. 4. That the Foundation be made to diminifli as it rifes, but yet fo, that there may be as much left on the one fide as on the other ; fo that the middle of that above may be perpendicularly over the middle of that 220 F O U that below, which ought in like manner to be obferved in diminifliing the walls above ground ; for by this means, the building will become much ftronger than it would be, if the diminution were made any other way. 5. That you ought nev^r r:^ build upon the ruins of an old Foun- dation, unlefs you are well aflured of its depth, and ihat its ftrength is futiicient to bear the building. Laftly, there is a curious precept in the writing" of fome ancient ar- chiteds, that the Hones in the Foundation llaouH be laid as they natu- rally lay in the quarry ; they fuppofing them to hwe more ilrength in their natural pofition. This precept is generally obferved by all good modern artilts, not only in the Foundation, but alfo in all the parts of the fu- perftru6lure j and for a better reafon than that of bare conjeiflure, viz. becaufe they find the ftones to have a cleaving grain, or that they are fub- jedl to cleave that way of the ftone that lay horizontally in the quarry ; and for that reafon, if the horizontal poiition of the flones in the quarry fhould be placed vertically in the building, the fuper-incumbent weight would be apt to cleave them, and fo render the building ruinous. For, as it has been oblerved by Philip de Orme, the breaking or yielding of a flone in the Foundation, although it Ihould be but the breadth of the back of a knife, it will make a chft of more than half a foot in the fa- bric aloft. In fome places they found the piers of bridges, and other buildings near the water, on facks of wool laid like matraffes, which be- ing well prefled and greafed, will never give way nor rot in the water. Of all the ancients, fays M. Gautier, in architedture, who have left us any rules for the founding on bridges, Scamozzi is the only one that has faid any thing to the purpole. He tells us, that the Foundations are laid after different manners. The firft is by encloling all round the fpace of ground you would build upon, by dams made with piles fet deep in the ground in double rows, well ftrengthened and bound together with crofs pieces and cords, and filling the vacant fpaces between them with chalk, or other earthly matter. This being done, the water muft be emp- tied out, and the Foundation dug according to the quality of the 'ground, driving down piles, if it be neceflary, upon which the walls of the Foundation mull: be laid. But this method is only pradicable in building, on luch rivers where the water is neither very rapid, nor very deep. The fecond is done by laying the Foundation on grate-work, rafts of flout oak well bound together, and made faft at the llirface of the water with cables or machines, and building upon them large quar- ters of Ifone cramped together, and jcined with good mortar or cement, and afterwards letting them defcend Ibftly by thofe cables and macliines perpendicularly to the bottom of the water, as he fays was done in the time of the emperor Claudius, at the port of Oftia ; and as Draguet Reys ^id in the laft century at Confiiaatinople, in the fine mofque that he built upon F O U 221 upon the fea. This manner requh-es a good bottom, equal and very even. The thu'd is by drav/ing off all or greateft part of the water of the river into fome other place, or by digging it another bed, or letting it out into deep ditches, in which, fays he, great diligence muft be ufed, to have all the materials ready, and to have workmen enough ready, fufficient to com pleat it in a Ihort time, to the end that the matbnry may be well confirmed and fettled before there is a neceffity to let the river into its for- mer bed. The laft method, which is that which Scamozzi fays he believes Trajan made ufe of in building a bridge over the Danube, is to dig a new bed for the river, in a place which feems, as it were, to meet itfelf, after having made a great elbow or compafs about, which being done, the bridge may be built with eafe, and that dry fliod, in that place. And wheti the bridge has been fettled, to open the paflage of the current at the two ends, flopping the bed up with ftrong banks or moles, and fo the river will take to its old courfe again j thi^ fays he, is the furefl method of aU, To lay the Foundation of the piers of a bridge, if the eartli be foft, it muft be piled, after as much of it has been carried away as can well be. The lame is to be done, if it be fand or gravel, which muft be dug out as deep as can be, all round about, to a reafonable diftance, which muft be furrounded with pointed piles or ftakes well faftened to one another, filling the fpaces between pile and pile with chalk or folid earth well rammed in, which will for a time hinder the current from wafhing away the piles and fand, and ruining the work. The piles ought to be made tapering from top to bottom ; the arches unequal in number, and carried up higher than the higheft inundation. The architefture of bridges ought to be plain and rullic. Scamozzi afterwards gives the delign of his fine bridge of ftone, and another of carpentry. The profile of this laft may be feen in La Hire's Treatife of Carpentry. M. Blondel relates the method he made ufe of in laying the Foundation of the bridge of the Haintes, which he caufed to be built over the Cha- rante. The ancient bridge had been borne down, it having been built on potters earth or clay, and piled, fo that the fwelling of the Foundation had raifed the piles, and threw down the bridge. The piles, by the fwelling of the clay, ftarted out above a foot higher than the level of the reft. The plummets went into this clay, to the depth of fixty feet, made with a large borer, the arms of which were of iron, each three feet in length, and well jointed one into another with good pins. After they had caufed it to be dug {even feet below tlie bottom of the water, all the work being counterguarded and encompafled with a good dam, and the hollow^nefs raked level, then a grate- work of g-ood oaken wood was laid all over the Foundation, of twelve or fourteen inches in thick- L 11 neft. 222 F O U nefs, and fquare the whole length and' breadth of the building, not only ♦hat part that was piled, but alio the opening or fpace between the piers and abutments of the bridge, or the void fpaces of the arches. The chambers of the grille, or grate- work, filled with good quarters of hewn ftone, and the upper part covered with planks of five or fix inches thick, well faftened on with pins all over the grate-work. Afterwards upon this work of carpentry is kid a Foundation of mafonry five feet thick, all level wi,th good hewn flones, well faftened together with cramp-irons. Upon. this flat Foundation of five feet thick, the piers are.erefted, which for the firft year are brought no higher than the imports, to the end that they may fettle well during the winter . M. Blondel makes it appear, that whatever precautions architects take to fecure their works by good Foundations, yet they are very conjedlural- and uncertain. He in this compares an architeil to a phyiician, who pro- ceeds only upon conjedtures. For who can venture to fay, fays he, that building upon a Foundation of confiftence as it appears to him to be, that he fliall not meet with foft or bad ground underneath, which the weight of the building will prefs down and fiiik into, and by that means be overturned. Upon this occafion, fays M. Gautier, I can give an exam-. pie tliat happened in one of the illes of Oleron or Rhe, where the king caufing fortifications to be built, one face of the wall funk, or fell down, , notwithftanding it was built on a bank of rock; becaufe it had a hollow underneath, which could not- be, or was not difcovered._ Blondel alfo relates in confirmation of whathe has fiid, that the vaft walls of the church of Val de Grace, funk on one fide, though built upon a good foundation ; . becaufe there were underneath large hollows which had been made in former times for taking out of ftones fome fathoms lower, there having been a quarry there. Michael Ange Bonarote caufed the foundation of the dome of St. Pe- ter's, Rome, to be laid with all the precautions imaginable. But for all that, this work did gape or fplit, which they cured by binding it about ' with a hoop of iron of an extraordinary breadth and thicknefs, which cofi 100,000 crowns. It is fuppofed, that this fradlure in the dome is an effedl of the waters of a lubterraneous fource, from a fpring which runs down from the high mountains of the Vatican and Janiculus, which have waflied the Foundations of this huge edifice. So that, according to thefe examples, nobody can be anfwerable for the Foundations of a building. The Corderie of Rochefort, the defigns of M. Blondel, is in length two hundred and fixteen toifes, not comprifing the pavillions that are at the two ends, and four toifes, the breadth between the walls, the two flories, built upon a grillage, or grate-work, as well in the full, as in the void of ten or twelve inches thick, laid upon a bottom of potters clay. Upon F R E 223 Upon this grillage arc laid platforms well faftened together with pins^ and upon them a coach, or courfe of hewn ftones, and good rough flones, the building being raifed every where level continually, that it may be every w^here equal, that there may be no more weight on the one fide than the other, that all the parts of the work may be in aqiiUihrio. This building thus raifed, has fucceeded perfedly well. M. Blondel remarks further, that the materials at Paris not being of the fame folidity as thofe of Italy, as perhaps marble, and harder, will not permit to make bridges at Paris with fo much delicacy and fo difengaged, as thofe which are made in Italy ; which have a great deal lefs thicknefs at the place of the keys of the arcades. Frame, among painters a kind of fquare, confifting of four long flips of wood joined together, whofe intermediate foace is divided by threads,, into feveral little fquares like a net. It ferves to reduce figures from great to fmall ;. or, on the contrary, to augment their fize from fmall to great. Framing of an Houfe, among carpenters,, denotes all the timber work therein ; namely, the carcafe, flooring, partitioning, roofing, cieling,, beams, aflierling, 6cc. all together. French Order, an Order, as we arc content to call it, in which the proportions are the fame as in the Corinthian, but the capital is decorated with cocks heads and flower-de-luces. There are fome columns of it in the grand gallery at Verfailles, but fuch a variation from the antique does not deferve the name of a difl:ln6t Order. Fresco, a method of painting, or rather plaifbring on walls to endure the weather, and reprefenting birds, beafts, herbs, fruits, &c. in relief. It is performed on frelh plaifter, or on a wall laid with mortar not yet ,dry, and with water-colours. This fort of painting has a great advantage, by its incorporating with the mortar and drying along with it, it is ren- dered extremely durable, and never fails or falls but along v/ith it. ^ Of the method of this painting : to make the compoft or plaifter of old rubbifli flones, and mix it with well-burnt flint (or lime) and water ; but wafli out the faltnefs of the lime, by often pouring the water, and putting frelh to it. This Qiould not be done in moift weather, becaufe that has a great influence on the walls. And in order to render the plaif- ter the more durable, they ftrike into the joints of the brick or ftone-wall flumps of horfe-nails, at about fix inches diftance, to prevent the plaifter from peeling off. With this plaifter the wall is firft to be plaiftered a good thicknefs, and left for fome time dry j and the dengns and colours- being firft ready prepared. This painting is chiefly performed on walls and vaults newly plaiftered with lime and fand ; but the plaiftering is only to be laid in proportion as the painting goes on, no more being to be done at once than the painter can difpatch in a day, while it is dry. Before the painting is begun, there is ufually a cartoon or defign made on paper, to 22+ F R B to be calked and transferred to the wall, about half an hour after the plaifter has been laid on. The colour being prepared and mingled, the wall is to be plaiflered over again a fecond time about the thicknefs of a half-crown, but only fo much as you intend prefently to work upon ; and while it is wet, you muft work the colours therein, which will mix and incorporate with the plaifter, fo as never to wafh out. The painting muft be, for the work to come out in all its beauty, wrought quick, and with a free hand : for there can be no alteration after the firlt painting, and therefore make your colour high enough at firft ; you may deepen, but not eafily heighten. Nor, muft they ever be retouched dry, with colours mixed up with the white of an egg, or fize, or gum, as fome workmen do, by reafon fuch colours grow blackilli ; nor do any preferve themfeives, but fuch as were laid on haftily at firft. In this painting all the compound artificial colours, and almoft sll the minerals are fet afide, and fcarce any thing ufed but earths ; which are capable of preferving their colour, defending it from the burning of the 'lime, and refifting its fait, which Vitruvius calls its bitternefs. The co- lours ufed are white made of lime flacked long ago, and white marble duft ; oker, both red and yellow, violet red, verditer, lapis lazuli, fmalt, ..earth, black Spanifli brown, Spanilh white, &c. All which are only ground and worked up with water ; and moft of them grow brighter and brighter as the Frefco dries. The ancients painted on ftuck ; and it is worthy obfervation in Vitru- vius, what infinite care they took in making the incruftation or plaifter- ing of their buildings, to render them beautiful and lafting : though the modern painters find a plaifter made of lime and fand preferable to ftuck, both becaufe it does not dry too haftily, and as being a little brownifli, it is fitter to lay colours on, than a ground fo white as ftuck. This kind of painting was the ancient Grecian way of painting, and fince much ufed by the Romans. Plutarch informs us, that Aratas, the chief commander under Ptolemy king of Egypt (in a compliment to the emperor's affedions that way) forbore to fack a wealthy city, merely for the excellency of the .Frefco painting upon the walls of the houfes. There have been feveral whole towns of this work in Germany, excellently well done, but now ruined by wars. At Rome there are three chambers (in the pope's palace) of Frefco, Aone by Raphael Urbin, and Julio Romano, his difciple, who finiflied his mafter's work, which is yet called Raphael's defign. There are other places done by Andrea del Sexto and Michael Angelo, and fome other artifts. There is an excellent Frefco work at Fountainbleau in France. It is the continued travels of Ulyfl*es, in fixty pieces, done by Bollmneo Martin Roufe, a Florentine, and others. Fret, or Frette, in architedure, is a kind of knot or ornament, iConfifting of two lifts or fmall fillets varioufly interlaced or interwove, 2 and F R I 225 and running at parallel diftances equal to their breadth. Every return and interfertion of thefe Frets muft be at right angles. This is fo indifpen- fibly necefliiry, that they have no beauty without it, but become perfect- ly Gothic. Sometimes the Frete confifts but of a lingle fillet, which however may be fo ordered, as to fill its fpace exceedingly well, if well managed. Thefe Frets were very much in ufe among the ancients, who applied them chiefly on even flat members, or parts of buildings ; as the faces of the corona, and eves of cornices ; under the roofs, fotiits, &c. on the plinths of bafes, &c. The name of Frette was hence occafioned, the Frette literally fignifies the timber- work of a roof; which confifts chiefly of beams, rafters, 6cc. laid acrofs each other, and, as it were, fretted. Fret-Work, an enrichment of frette, or a place adorned with fome- thing in the manner thereof. Fret-work is fometimes ufed for the filling up and enriching flat empty fpaces, but it is principally pradtifed in roofs which are fretted over with plaifter-work. The Italians alfo ufe Fret- work in the mantlings of chimnies with great figures, a cheap piece of magnificence, and as durable almoft within doors, as harder matters in the weather. Frieze, in archltefture, a member in the entablature of columns ; it is the middle part, and feparates the architrave and cornice. The Frieze is flat in all the orders ; but in moft of them is intended to receive orna- ment. In the Tufcan it iliould remain plain ; in the Doric it is eflenti- ally divided into two parts, under the names of triglyphs and metopes ; the triglyphs are channelled figures, and the metopes are the fpaces be- tween them ; thefe triglyphs are not capable of alteration, but the orna- ments in the metopes are varied at pleafure, and frequently they are left plain. In the Ionic the Frieze is fometimes made to fwell, which is an objedion to the general rule of their being flat, but this is an innovation : in the Corinthian and Compofite the Frieze is decorated varioufly at the pleafure of the architect, with figures of any kind, and is often a very elegant part of the order. The Friezes of the Corinthian order, at Pal- myra are very richly decorated. In our common door-ways for perfons of bufinefs, where there is an attempt towards any orders the Frieze is the part which receives the name, or other infcription. In the Corin- thian and Compofite orders the Frieze is often joined to the architrave by Iweep : the height of the Frieze is in general three-fourths of that of the arcliit.ive, but not ftridtly or exadly. When it fwells, as in the Ionic order, it is called a pulvinated or culliioned Frieze. Some write the vvcrd Freeze, or Frieze, and others Phrize ; this laft fpelling brings it nearer what is p^-etended by many to be its origin, the word Ploj-ygio, an embroiderer ; the ornaments oi Friezes, in the richer orders, reprefenting embroidery. M m m When 226 - FUN Wlien tiie Frieze Is decornted with fculptures, it is frequently named according to their nature j thus hiftorical Friezes are thofe reprefenting hiflories by figures, marine Friezes are thofe with fhells, tridents, and fea-horfes, and fo of the others : but the moll: frequent in ancient build- ings are thofe on which religious ceremonies, the inftruments of facrifice, and other fuch matters are figured. We fee inflances very common in fmall buildings, in which the architedl has taken the liberty to retrench the Frieze entirely, and to make the cornice rell upon the architrave ; but this always offends the eye, and is extremely wrong, llie Frieze is introduced into an entablature to fhew a natural Ipace, and the thing which reprefents it cannot be fupprefi'ed without impropriety. Front, in perfpeftive, aprojeftion or reprefentation of the face or fore- part of an objedl, or of that part diredly oppofite to the eye. Frontal, in architedlure, a little fronton, or pediment, fometimes placed over a little door or window. Frontispiece, in architedlure, the word is fometimes ufed to exprefs the whole decoration of the front of a church ; fometimes for a particular compartment raifed over gateways, and in other places, fupported and en- compalfed with figures, or other ornaments, and intended to hold an em- blem, a coat of arms, or infcription. Fronton, this term is ufed by thofe who follow the French authors for what we call a pediment, An ornament that crowns the frontifpieces cf of buildings, and is ufed over doors and windov/s. It is properly of a triangular form, and not very high in proportion to the extent of its bafe, i)ut the architefts hive deviated from this, and made it arched, and often broken, to admit bufts or figures. Frowey. Workmen fay timber is Frowey, when it is evenly tempered all the way, and works freely without tearing. Funnels of Clnmm'es. The Funnel is the fhaft, or fmalleft part from the walle, where it is gathered into its leafi: dimenhons. Palladio di- refts, that the Funnels of chimnies be carried through the roof, three, four, or five feet at leail, that they may carry the fmoak clear from the houfe into the air. He advifes alio, that care be taken as to the width of them ; for that if they be too wide, the wind will drive back the fmoak into the room ; and if they be too narrow, the fmoke will not be able to make its way. Therefore chamber chimnies muft not be made nafrower than ten or eleven inches, nor broader than fifteen ; which is the ordi- nary depth of the P'unnels of great kitchen chimnies, whofe breadth is four or five feet within the work, from the place where the breil ends, to the top of the Funnel. Now the faid brefi reaches from the mantle- tree to the cieling or pitch of the arch, always diminilhing within the work, till you come to the meafures of depth and breadth before-men- tioned ; and from thence to the end of the Funnel, it mufl be carried \:p I as GAT 227 as even as it poflibly can be j for if there be a failure in this, the fmoke happens to be offenfive. Furring, in architedlure, is the making good the rafters feet in the cornice. Thus, wlien rafters are cut with a knee, thefe Furrings are pieces which go ftraight along with the rafter, from the top of the knee to the cornice. Ahb when rafters are rotten, or funk hollow in the middle, there are pieces cut thickell: in the middle, and tapering towra-ds each end, which are nailed upon them to make them flraight. Such pieces are called Furs,. and the putting them on. Furring the rafters. FusAROLE, in architedlure, is a moulding or ornament placed imme- diately under the echinus in the Doric, Ionic, and Compofite capitals. The Fufarole is a round member carved in manner of a collar or chaplet with oval heads. The Fufarole fliould always anfwer exadly under the eye of the volute in the Ionic capital. Fust, in architecture, is the fhaft of a column, and that part which is contained between the bafe and the capital, and may be called the trunk or body of the column. This part is commonly plain, fometimes fluted ; and the flutings are fometimes empty, fometimes filled up at the bottom,, with a ftrait, round or twifted piece, which is called a cable. Sometimes alio the Fuft is ornamented with ruflic, or othcrwife. The word is French, and literally lignifies a calk. But fome derive it from xhc Latin fiijiisy a. - club. G. Gable-End of a Hoiife, is the upright triangular end from the cornice or caves, to the top of its roof. Gain, the levelling fhoulder of thejoifts, or other fluff. It is alfo ufed for the lapping of the end of the joifts, &c. upon a trimmer or girder; and then the thicknefs of the fhoulder is cut into the trimmer, alfo levelling upwards, that it may juft receive the Gain, and fo the joifl and trimmer lie even and level v/ith their lurface. Thi^ way of working is ufed in floors and hearths. Gallery, in archite ferred for the warmeft ffove, its fituation being fuch, as that the fun, upon his firff appearance in the morning, Ihines diredly upon the glaffeo, which is of great fervice in warming the air of tlie houfe, and adding life to the plants, after having being fhut up during the long nights in the winter feafon. Thefe wings may be allowed fixty feet in length, and may be divided in the middle by partitions of glafs, wi-th glafs doors to pafs from one to the other. And the fire-place may be fo ordered as to. warm both divifions, by placing an iron regulator in the flue, fo that fmoak may pafs through the flues of which part focver you pleafe. By this contrivance you may keep fuch plants as require the fime degree of heat in one part of the houfe, and thofe which will thrive in a much lefs- warmth in the other part. The other wing of the houfe facing the fouth-weit may alfo be di- vided in the fame manner, and flues carried through both parts, which may be ufed according to the feafons, or the particular forts of plants which are placed therein. So that by this difpofition here will be four di- vifions in the wings, each of which may be kept up to a different degree of heat, which, together with the green-houfe, will be fufiicient to en- tertain plants from all quarters of the world. And without having thefe feveral degrees of warmth, it will be impofiible to preferve the various- kinds of plants from the feveral parts of Africa and America, which are every G R O 235 every year introuuced into the gardens of the ingenious. For when plants from very different climates are placed in the iame green-houfe, fome pe- rilh ibr want of heat, while others are deftroyed by having too much of it ; and this is often the cafe in fuch green-houfes, where there are large coliedtions of plants. Grotesqjje, fomething whimfical, extravagant and monftrous. The word is alfo particularly applied to a work or compofition in fculpture or painting in the Grotefque manner or tafte, confifting either of things that are ir.crely imaginary, and have no exiftcnce in nature, or of things turned and diftorted out of the way of nature, fo as to raife furprize and ridicule. Grotefque work is the fame with what is fometimes called an- tique. The name is faid to have taken its rife hence, that figures of this kind were in ancient times much ufedin adorning the grottos, wherein the tombs of eminent perlbns or families were inclofed ; fuch as that of Ovid, •whofe grotto was difcovered near Rome, about one hundred years fince. It is particularly ufed to fignify thofe frnciful ornaments of animals, inter- fperfed among foliages, fruit, &c. as thofe painted by Raphael Urbin in the Vatican, and thofe carved by Michael Angelo, in the cicling of the portico of the capitol. Grotto, is a large deep cavern in fome rock or mountain. It is alfo a fmall artificial edifice made in a garden in imitation of a natural Grotto; The outfides of thefe Grottos are ufually adorned v»^ith ruftic architefture, and their infide with fliell-work, coral, &c. and alfo furnilhed wdth va- rious fountains, and other ornaments. A Grotto may be built with a little expence of glafs, cinders, pebbles, pieces of large flints, fhells, mofs, flones, counterfeit coral, pieces of chalk, &c. all bound or cemented toge- ther with a proper cement. Ground, in painting, the furface upon which the figures and other ob- jedls are reprefented. The Ground is properly underftood of fuch parts of the piece as have nothing painted on them, but retain the original colours upon which the other colours are applied to make the reprefentations. A building is faid to ferve as a Ground to a figure, when the figure is painted on the building. The Ground behind a picture in miniature is commonly blue or crimfon, imitating a curtain of fattin or velvet. Grove, or Groove, in joinery, &c. a term ufcd to fignify the channel that is made by their plough in the edge of a moulding, Itde, or rail, 6cc. to put their pannels in, in wainfcotting. , Group, in painting and fculpture, an aflemblage cf figures, of men, beafts and fruits, &c. which have fome apparent relemblance to one ano- ther. It is necelTary, in a good piece of painting, that all the figures be divided into Groups ; this has fomewhat in it of the nature of fymphony or concert of voices ; for as in the one the voices mufi: fuftain each other, in order to fill the ear with an agreeable harmony from the v;hole ; fo in Z Groups, 230 GUT Groups, if the parts or figures are not well difpofed, fomething will be found diiligrecable. A Group of columns, in architedlure, is ufed when we fpeak of three or four columns joined together on the fame pedeftal j but when there are but two, the word couple is ufed, and not Group. GuTT^, in architecture, ornaments in the form of little cones, in the platform of the Doric cornice or architrave, underneath the triglyphs, re- prefenting a fort of drops or bells, ufually lix in number. They are fome- times called lacryms, campans, or campanula. Gutters, in architefture, a kind of canals in the roofs of houfes, ferving to receive and carry ofF the rain. Thefe Gutters are of two kinds in refped: to their pofition, for they are either fuch as come near a parallel with the horizon, or fuch as incline in a vertical pofition to the horizon. The firft kind of Gutters may be called parallel Gutters, and may be diftinguiflied into three forts, which are covered with lead : i. Either it is a Gutter between two roofs, which fland parallel to each other, being made upon the feet of the rafters of two roofs, which meet together : 2. A Gutter where a building has a cantaliver or modillion cornice, which projefts one foot and a half, or two feet beyond the walls, then the roof is fct with the feet of the rafters no flirther out than the wall, but rather within it, fo that the joifts of the upper floor lie out beyond the walls, and alfo beyond the feet of the rafters, which is covered with lead. The third fort of thefe parallel Gutters are in flat roofs, w'hich are ufually called platforms, where are alfo Gutters for the water that run from the platform to defcend to, which is from thence conveyed off from the building by leaden pipes. In the laying of parallel lead Gutters, great care Ihould be taken t!iat tlae Gutter boards, &c. lie not too near p'.mllel with the horizon, but in fuch a pofition that there may be a good current, for if it be laid too near a level, the water will be very fubjedt to fland in plafhes, if it chances to flick a little in the middle, which fome Gutters are apt to do. Some Gutters have a layer of fand for the lead to lie upon, but there are reafons that render this method not approveable. Becaufe ib:"ne lorts of fand does very much corrode and decay the timber that lies near it ; and when a Gutter is laid on fand, a very fmall weight fidling on it v/ill make dents in it, and in thofe dents the water will lland, and this v/ill be a means of decaying the lead the fooner. In laying of leads for Gutters upon boards, it is common for plumbers to folder them when they are fo long, that a flieet of lead will not reach. In doing this, they ufually cut a channel crofs the Gutter-boards at the end of the Iheet where the foldering is to be, and to beat dow.n the ends of both the (beets that are to meet here, into the channel, which, :-vhen it is done, there will remain a little cavity, which is filled up with the GUT 237 the folder level with the reft. The lead which is ufually laid in Gutters is that which weighs about eight or nine pound to the foot. Vertical Gutters, are fuch as are made by two roofs meeting at right angles one to another, or, which is the fame thing, made by the end of one roof joining to the fide of another. Thefe Gutters are made either of lead or tile. As to thofe made with lead, unlefs the builder will be at the charge, they need not be altogether fo thick for thefe vertical ones, as for the parallel ones ; for thele vertical ones will laft as long, if laid with lead of about fix or feven pound to the foot, as parallel ones with lead of nine or ten pound to the foot. Gutters laid with tiles, are alfo of two kinds : thofe made of concave or Gutter-tiles, and plain tiles. In the plain tile-gutters, there is a Gutter- board laid, which raifes them from pointing to an angle. And in laying on the tiles, the workman begins at one fide of the Gutter, and fo works acrofs, as if it were plain work, and then brings the next row of tiles back again ; fo that he works from right to left. Gutters which are laid after this manner, are not angular, but of a diftorted curvilineal form ; by which means they are not fo fubjedl to be furred up with the mortar which wafhes out of the adjacent tiles. In laying of three point Gutters, they begin and lay one tile on one part of the roof, it is no matter which part firft, and lay one corner of the tile juft in the middle of the Gutter ; and then lay another on the other part of the rocf, with its corner juft in the middle of the Gutter, alfo that the corner of the fecond tile is contingent with the firft ; and then lay another tile in the Gutter, v/ith its corner, as it were, betwixt the other two, and to them. When they have done thus, they proceed in the work, and lay a tile on each part of the roof, as before, and an- other betwixt them in the Gutter, proceeding in their work in this man- ner, till they have finiflied the Gutter. And this is what is called the three-point Gutter : for three points, or angles of tiles, always come to- gether. Here you are to take notice, that only three inches fquare of the middle tile is vifible, if the gage be feven inches, the reft of that tile be- ing covered with the next row of tiles above it. Thefe Gutters are very handfome, and if well done, fecure alfo ; yet if they let the water into the houfe, by reafon of fome ftoppage, or broken tile in the Gutter, they are very troublefome to mend. Either of thefe plain tile Gutters are cheaper to the mafter-buikler, than concave ones ; becaufe plain tiles are cheaper than Gutter tiles, they being in many places not above one-fourth part of the price. GuTTER-TiLKs afe of a quadrangular form, confifting of two ftreight fides, of about ten inches and a half long, and of two circular fides, the one convex, the other concave j the convex fide is about fourteen inches, and the concave one about two inches. This is their form as to their P p p edges 238 HAL edges or fides. With rerped: to the plane; at the little end they are bent circular, and fo likewile at the convex great end, at firft like a corner tile ; but then they bend the corners of the great end back again ; fo that if a perfon look againft the end of the broad edge, it confifts of a circular line betwixt two ftraight ones. This you are to underfland, is when you hold the concave fide of the tile downwards. Thefe tiles are laid with their broad ends and hollow fide upwards. H. Hall, In architeflure, a large room at the entrance of a fine houfe and palace. In the houfes of minifters of flate, magiftrates, &c. it is the place where they difpatch bufinefs, and give audience. In very magnificent build- ings, where the Hall is larger and loftier than ordinary, and placed in the middle of the houfe, it is called a faloon. The word Hall in old writers is ufed for a manfion-houfe, and to this day, in many parts of the kingdom, gentlemen's feats are called Halls. In town a Hall is a place of reception for fervants ; therefore in this,, neither magnitude nor elegance are ufeful j in the country, where there are other ways into the houfe, the Hall may be an elegant room, and it is there- we propofe its being made large and noble. It ferves as a fummer-room for dining j it is an anti-chamber, in which people of bufinefs, or of the fecond rank, wait and aniufe themfelves ; and it is a good apartment for the recep- tion of large companies. A good Hall has many other ufes, am.ongft which are the reprefentation of theatrical pieces. Thefe are reafons for the fpaci- oufnefs of a Hall ; but then, if the rule of general proportion be not ob- ferved, the bignefs of this room may make all thofe look little into which we pafs afterwards. It IS a fafliion in fome places, to give Halls the form almofi: of galleries ;• to make them very long in front and very fliallow ; this anfwers the purpofe of giving room behind, but it is an ill way of getting it. Halls of any con- fequence are feldom thought of unlefs for large houfes in the country ; and there it will be eafy to take in a few more feet of ground, and not to make the Hall a flip, in order to give depth to the parlours. The proportion of breadth to length fhould be very confiderable in a Hall. Palladio lays that it may be made twice as long as broad, but never fliould exceed that length. This is indeed carrying the length of a Hall to the full proportion i and that author adds, with great juflnefs, that the nearer they approach to fquare the better. From what we have obferved upon a variety of inftances, it feems, that from one and a third to one and a half the breadth, is the proper and mofl proportional length of a Hall. The befl height for a Hall is fomewhat lefs than its breadth, but here HEX 239 here we are to confider the difference of flat and arched ciehngs, as in other rooms. In thofe Halls which have coved cielings, the height may be withia a twelfth part the meafure of the breadth ; but in thofe with the cieling fiat, four fifths of tlie breadth is a very good general proportion ; however in this the architeft has a great deal of latitude for the laving room above ; for the Hall may be lower than either of thefe allowed proportions, and yet not liable to great cenfure. Harmony, in architedure, is an agreeable relation between the parts of a building. In painting, both in the compofition and colours of a pidlure : the former denotes the connedion between the figures, with refpeft to the fubjedt of the piece ; in the colouring it denotes the agreeable mixture of different colours. M. de la Chambre derives the Harmony of colours from the fime proportions as that of founds. On this principle he lays down green as the mofl agreeable colour correfponding to the odave ; red to a fifth, yellow to a fourth, 6cc. He AD, in architediure, an ornament of carved work, or fculpture, frequently ferving as the key of an arch, or platband on other occafions. Thefe fort of Heads ufually reprefent fome of the heathen deities, vir- tues, feafons, ages, &c. with their attributes, as a thunderbolt for Jupi- ter, a diadem- for Juno, a trident for Neptune, a crown of ears of corn for Ceres, a helmet for Mars, a caduceus for Mercury, &c. The Heads of beaffs are alfo ufed in places fuitable, as an horfe's head for an equerry ;. a deer's, or boar's head, for a park or foreff j a dog's head for a kennel ; a bullock's or flieep's, for {hambles, or a market-houfe. In metopes, friezes, and other parts of certain antique Doric temples, we fee repre- fentations of bullocks or rams heads flead, as a fymbol of the facrifices offered there. Heads with bricklayers, a term ufed to fignify half a tile in length, but to the full breadth of a tile ; thefe they ufed to lay at the eaves of a roof. Helix, in architecfture. Some diftinguiOi between it and fpiral. Da- viler fays a flair-cafe is helical, when the Heps wind round a cylindrical newel ; whereas the fpiral winds round a cone, continually approaching nearer its axis. Helix alfo denotes, in architedlure, the caulicules or little volutes under the flower of the Corinthian capital, called likewife urillae. Thefe Helixes ot the Corinthian however give it fome diflant refemblance of the Ionic, though when examined they are found to be fmaller and more numerous. The word comes from the Greek, which originally expreffes a twifled flialk of ivy, but from thence is made to reprefent any thing that is twifl:ed or fpiral. Hexastyle, in ancient architedure, a building with fix columns in front. HiNGESj 240 H O U Hinges, in building, thofe iron or brafs joints, whereby doors, tables, &c. open, fliut, or fold, &c. Of thele there are various fpecies. Hippodrome, a kind of building eredled by the ancients for the exercife andfportings of their horfes. It was fpacious, of a long form, circular at the two ends, and encompafTed, The fame word is fometimes alfo ufed to exprefs the place where they ran their races. HiP-RooF, among carpenters, called alfo Italian roof, is a roof which has neither gable-head, fliread-head, nor jerken-head, by which is meant fuch heads as are both gable and Hip at the fame end j for it is a gable or up-right as high as the collar-beam, and then there are two fhort Hips, which fliut up with their tops to the tops of a pair of rafters, which country carpenters call fingulars. Hod, a well known inftrument ufed by labourers to carry bricks, mor- tar, &c. in, at the building, or repairing of houfes, &c. Hollow, in architedture, a concave moulding, about a quarter of a circle, called by fome a cafement, and by others an abacus. House, in architefture, a habitation or place built with conveniencies for dwelling in ; thus we fay town Houfe, country Houfe, &c. It will not be improper, in this place, to fpeak of the original conflrudion of houfes. Caverns and arbours were undoubtedly the firfl: habitations, for nature's own hand conftrudled thefe, and men, deftitute of better fecurity, would take to them and finilh them ; but thefe, though the firft houfes, could not be long their only habitations. The mud wall tenement naturally rofe firft, for we may very well believe that early cabins were built with clay. The fun would harden thefe rude walls by its heat, and thence the mind of man would foon conceive the method of cutting out the wet clay into fhapes, and drying it before ufing in his Houfe. Thus bricks miift have been an early invention, and they would doubtlefs have been in univerfal ufe, had not nature difclofed to thofe who dug for this poor material, her mines and ftores of ftone and marble. From the fight of thefe greater and noble materials, men conceived the ideas of greater build- ings. This is the plain and natural courfe of things, and this probably was the origin of architedure ; but when it happened, or what quarter of the world, are points which dreaming monks might better Itudy than people who enjoy the prefent advantages of fcience. It is enough for us to acknowledge the defedl of information ; and, while we trace the pro- grefs of the art thus from reafon, to fay it is too old for hiftory. Man's fenfe of feeling told him that he wanted a houfe for flielter and defence ; and his reafon, given him by the Creator for that purpofe, taught him how to fet about it. The next thing to be confidered is, the giving the edifice a proper flrength ; the Houfe is to be fuited either to the condition of the peifjn 4 who H O U 241 who is to Inhabit it, or to the place where it ftands ; the firft is the point in building by commiffion, for a family , the other in building for a chance of letting. The latter is the common pradlice in great towns ; but, even in that, there is fomething to-be confidered with refpedt to fuiting to the inha- bitant. Though the archited; in this cafe will not know who is to live in his edifice, yet he can very well guefs of what rank he will be, and this ac- cording to the place whej-e it ftands ; thus much is to be confidered in building in this general and random way ; the ftreet, or fquare, the neigh- bourhood, the conveniences, and the other concurrent circumftances, will inftrudt the builder ; for he would be very indifcreet who ihould build a fhed in Grofvenor-fquare, or a palace on Salt-Petre Bank ; and thus far he will be able to proportion the building to the tenant, or purchafer, though unknown. After this firft confideration of the general condition and extent of the building, comes the article of ftrength. Whatfoever be the fize, the fo- lidity mufl: be proportioned : for when the houfe is not able to fupport itfelf, all other care Is loft upon it. We fee a ftrange difference between the buildings of earlier ages, and thofe of the prefent time, in refpedl of this article of ftrength, but the reafon is plain ; the nature of the tenures in London has introduced the art of building llightly. The ground land- lord is to come into poffellion at the end of a ihort term, and the builder, unlefs his Grace tie him down to articles, does not chufe to employ his money to his advantage. It is for this reafon we fee houfes built for fixty, feventy, or the ftouteft of this kind for ninety-nine years. The care they Ihall not ftand longer than their time occafions many to fall before it is expired ; nay, fome have carried the art of lllght building fo fiir, that their Houfes have flUlen in before they were tenanted. From this general pradllce, in the common way of working, has been introduced the lame condudl in better buildings ; and It is not often that we fee a ftrufture, like the Horfe Guards, built for pofterity. But whatever be the occafion, there is nothing that more deferves or demands the interpofition of the leglflative power ; the lafetyof the fubjedl is the concern of every wife government; and it is certain the prefent method of running up houfes in London, not only difgraces us in the eyes of ftrangers, but threatens continual difafters. Till fuch a coiitioul Ihall be laid upon bad builders by public authority, thofe who have more fklll and more integrity fliould diftinguilh themielves from them by their work. Two things give ftrength to a building, the choice of good" materials, and the putting them well together ; and the firft care, in the regard of ftrength. Is that the fupports be equal to the weight they carry ; thefe fupports are. In common buildings, plain walls. When walls are not able to fupport the incumbent force, recourfe is had to fpars and but- treffes j but thefe are an unfeemly and very dilagreeablc fight. To avoid Q^qq ' this. 242 H O U this, the archited fliould coniider in time what the force, or prefTure, will be, and proportion the ibhdity accordingly ; great arches are the moil: fub- jed to impair the ftrength of walls in this manner ; but they lliouid be lightened, and the wall llrengthened in tlie orift;inal ftrudure of the build- ing. The occalion on which buttrefles admit of moft excufe, is on the outlide of Gothic churches ; though in thefe a good architedl could have contrived to avoid the need of them, by lightening the arch, and Ifrengthening the wall in its plain, perpendicular form. When we fee this fort of fupport on any other cccafion, it is a great difgrace to the ar- chitedl. The architedl having thus, by an honeft choice of materials, and a judicious manner of proportioning the fuperftrucSture to the fup- ports, taken care of the main confideration of ftrength, the next regard is to be fliewn to proportion and regularity, in the diftribution of the fe- veral parts. The extent of ground being determined, the materials chofen, and the weight of the roof, and thicknefs of the walls, fettled in the builder's mind, he is next to coniider the article of proportion. Here is a fpace to be covered with building ; and the great coniideration is its divifion into parts, for different ufes, and their diftribution. In this regard is to be had two things, the convenience of the inhabitant, and the beauty and proportion of the fabric. Neither of thefe fl)ould be confidered inde- pendently of the other, becaufe if it be, the other will not fiil to be fa- crificed to it ; and this, which would be very difagreeable, is never abfo- lutely necelTary. If the houfe be for a perfon in trade, the firft and princi- pal attention muft be ftiewn to the article of convenience ; but with this the builder fliould always carry in his mind the idea of beauty, propor- tion, and a regular diftribution of the parts ; that whenever it can be done, he may favonr the one, while he is abfolutely confulting the fer- vice of the other j in the fame manner, when the houfe is for a perfon of failiion, the beauty and proportional difpoiition of the parts is to be prin- cipally confidered ; yet the great and needful article of convenience muft not be difregarded. In the building where there is to be a fliop, it would be abfurd to ihruft the parlour into the middle of it, in order to give that room an exadl proportion ; but, on the other hand, a little may be re- trenched from fome lefs confpicuous parts of the fliop, to enlarge that ne- ceflary apartment behind it. The merchant's Houfe muft have warehoufe room, but that need not break in upon every apartment, becaufe there is- no neceftity for any exadl inch of ground in a particular fpot for this ufe,, though there muft be a certain quantity upon the whole. The parlour, in a fmall private Houle, is a very convenient room ; but, as it is not the apartment of moft fhew, there is no neceftity it, (hould reduce the paflage to an alley ; and in larger Houfes, inhabited by perfons of diftindion, there muft be anti-chambers, and rooms where 4 people H O U H3 people of bufinefs may attend the owner's leifure. Thefe muft not be ill conftrufted, becaiife thofe of feme rank may often wait in them; and bende, every thing in a great Houfe fhould have an air of grandeur ; but, on the other hand, the care of rendering thcfe convenient and proper for their ufe, is not to extend fo far as to intrench upon the rooms of llate and elegance. The proportion of the feveral parts of an edifice is of two kinds ; for they are to be adapted, in this refped:, firft to the whole building, and afterwards to one another. It is ftrange to fee that many of our archi- ted:s, who have been able to plan out the whole of a good building, have inifcarried miferably in the proportion of its parts. It is in this the ancient aichitedts are found, by all that remains of them, to have been moll; particularly excellent ; tliey formed at once an idea of the whole ftrudlure tliey defigned, and of all its apartments, and it is evident they throughout kept that general idea always in remembrance. It is hence we fee fuch apeifecS hirmony in all their works. It is in this the ftudent who would difti.iguiili himfelf in architecflure fliould principal!/ follow them in the diipofition ot a houfe. The. firll kind of proportion is that of the feveral parts to tlie whole, and in this reafon is a very plain and general guide. We may divide Houfes under three heads, the laree, the middling, and the fmall ; and in each of thefe clalTes plain lenCc will didlate, that the leveral apartments lliould be of the fame charadler with the whole ; that the rooms in the large houfe fLould be large, in the middling, they fliouid be middling, and in the fmall they fiiould always alio be fmall. This is proportioning the parts of a building to the whole; and this rule, which is direded by common reafon, is confirmed by all the writers on architeftu re; for fciences are built upon reafon, and experience which fupports her determinations. The dimeniions not only of every room, but of every part of a Houle whatfoever, iLould be laid in a juft proportion to the extent of the ground plan ; for it would be abfurd to fee a great Houfe divided into a multitude of clofets, or a little Houfe confifting only of a hall and dining- room. Here proportion falls in with the rule of convenience ; for fuch a Houfe would not be more abfurd than inconvenient. The apartments being thus fuited to the Houfe in general, are next to be proportioned to one another ; this, one would think, v/ere as rational and plain a precept as the other, yet we fee it continually violated. Notliuig is more, com- mon than to fee a Houfe built for the fake of one room ; and in that cafe the red not being proportioned to that room, it feems not to belong to the Houfe, and there wants that fymmetry which is the great beauty in building. In Houfes which have been fome time built, and which have not had an out of proportion room, the common pradice is to build one to them ; this always hangs from one end, or iHcks to one fide, of the Iloufe, 244 HYP Houfe, and fliews to the moft carelefs eye, that though faftened to the walls, it did not belong to the building. The cuftom of routs has introduced this abfurd pradlice. Our fore- fathers were pleafed with feeing their friends as they chanced to come, and with entertaining them when they were there. The prefent cuftom is to lee tliem all at once, and entertain none of them ; this brings in the neceffity of a great room, which is opened only on fuch occafions, and which loads and generally difcredits the reft of the edifice. This is the reigning tafle of the prefent time, a tafte which tends to the difcou- ragement of all good and regular architecture, but which the builder will be often under a neceffity to comply with, for he muft follow the fancy of the proprietor, not his own judgment. Whatever the falle tafte oi any particular time may adopt, the builder though he complies with it from the orders he receives, yet he muft never fuppofe that the caprice, or fafliion, can change the nature of right and wrong. He muft remem- ber that there is fuch a thing as truth, though the prefent mode will not follow its fteps J and eftablifli it as a maxim in his own mind, that proportion and regularity are real fources of beauty, and always of conve- nience. In the difpofition of parts in an edifice, it is incumbent upon the ar- chited: to give a proportion and harmony to the whole building, and to make every part of it as fuitable to that whole as its nature will admit, yet he muft not endeavour to make all equally elegant. This has been the falfe tafte of fome, who have been profufe of ornament, and yet have not been able to give any real beauty. They have wondered at the ef- fect, but this is the reafon ; various parts of a Houfe are fuited to various fervices and purpofes, and they are not all to be contrived for fhew. The plainnefs of fome will fet off^, and Ihew to advantage the beauty of others. To avoid this error, when the archited: has laid down the dimen- fions of the feveral parts of the edifice, let him confider which of thefe are calculated for greater, and which for lelTer fervices, and accordingly dillribute among them all that gives dignity or plainnefs. There is no objeilion to plainnefs, when it is fuited to the occafion, and the variety between that and fuch apartments as are fpacious and elegant, gives a luftre even to the latter ; the plain decency of the humbler rooms, while it is proper, becaufe it fuits them to their purpofes, makes them alfo ferve as a foil to the others. Thus much may be fufiicient to mention in this place, concerning thofe ornaments whofe foundation enters into the original defign of the apartments, all other decorations we fliall fpeak of hereafter under their proper heads. Hypotrachelion, in architefture, denotes a little frieze in the Tuf- can and Doric capitals, between the aftragal and annulets, called likewife colerin. J O r S45 colerin, goi-fferin, &c. By fome it is applied to the neck of any column, or that part of the capital below the aftragal. I. Jamb, or Jaumb, among carpenters, an appellation given to door* pofts, as alfo to the upright porfs at the fides of window-frames ; and among bricklayers, it denotes the upright fides of the chimnies, from the hearth to the mantle-tree. IcE-HousE, is a building contrived to preferve Ice for the ufe of a fa- mily in the fummer lealbn. Ice-houfes are more generally ufed in warm countries, than with us, particularly in Italy, where the meanefl- perfon, who rents a houfe, has his vault or cellar for Ice. IcHNOGRAPHY, in architecture, a defcription or drajight of the plat-, form or ground- work of a houfe, or other building. Or it is the geo- metrical plan or platform of an edifice or houfe, or the ground- work of an houfe or building, delineated upon paper, defcribing the form of the feveral apartments, rooms, windows, chimnies, &c. In perfpedlive, the view of any thing cut off by a plane parallel to the horizon, jufl: at the bafe of it. Among painters it fignifies a defcription of images, or of an- cient ftatues of marble and copper, of bufts and femi-bufls, of painting in frefco, Mofaic works, and ancient pieces of miniature. Impost, is a term uftd to exprefs a fafcia, or a fmall cornice, which crowns a pier, or pilafter, and fupports the firft ftone from whence an arch fprings. Sometimes the entablature of the order ferves for the impoft of an arch, and this has a fine appearaiTce. Insulated, in architefture, detached from any other building. A church is infulated when it ftands contiguous to no other edifice, and fo of any other building. The word comes from the Latin, inliala, an ifland, thefe buildings being feparate from others as iflands are from the conti- nent, or neareft main land. A column that ftands alone, and free from any wall is called an Infulated column. The columns of the Periptere temples of the ancients were Infulated ; the monument in London is an Infulated column. Intercolumniation, in architedlure, implies the fpace between two columns, which is always to be proportioned to the height and bulk of the columns. Invention, in painting, the choice of which the painter makes of the objedls that are fo to enter the compofition of his piece. Joists, or Joysts, in archited;ure, thofe pieces of timber framed 'into the girders and fummers, on which the boards of the floor are laid. Joifls are from fix to eight inches fquare, and ought feldom to lie at a R r r greater 246 ION greater diftance from each other than ten, or at moll twelve inches, nor- ought they ever to bear a greater length than ten feet, or to be lefs inta the wall than eight inches. All Joilts on the back of a chimney ought to be laid with a trimmer, at fix inches diflance from the back. Some carpenters furr their Joifts, as they call it ; that is, they lay two rows of Joifls, one over another, the undermoft of which are framed level with the underfide of the girder ; and the uppermoft, which lie crofs the lower ones, lie level with the upper lide of the girder. Ionic Order, one of the three original orders of the Greeks, of a- middle nature between the Doric, which was their plaineft ; and the Co- rinthian, which was their moil ornamented. It is alfo the middle order of the five, taking in the two added by the Romans, the Tufcan and Doric being ilronger, the Corinthian and Compolite more ornamented. The. bale of the Ionic confifls of a torus and two cavettos, with aftragals be^ tween them. Vitruvius was the inventor of this bafe, which is liable to cenfure, becaufe fmaller, and confequently weaker in the lower than the- upper part. The ancients, when they gave a bafe to this order, ufed the, Attic : often they gave it none. Many give the Ionic the Corinthian bafe ; . but this, though better than its own, is not fo well as the Attic. The fliaft is eighteen femi-diameters, or nine diameters, in height j in fome- of the ancient buildings it has but lixteen femi-diameters, which is the. prefent proportion of the Doric j but the Doric was then lower : when* they gave the Doric fixteen, they raifed the Ionic to eighteen, to preferve. the dillindlion. When the £haft of the Ionic is fluted, the flutings iliould be twenty-four J and they are often filled up with a cable or baton fori one-third of the height, and the rell of their fpace left empty. Some, make the flutings of the Ionic thirty, in which they have the authority of: Vitruvius to fupport them. In thefe things architefts take great liberties : the only fluted Ionic column we know of among the remains of the antique, in Rome, is tliat in the temple of Fortuna Virilis, and the flutings there arc. only twenty. The capital in the Ionic order confills of three parts, an abacus, a rind,, which is the hollow of the volute, and an ovolo, under which is an aftragal,. The abacus fupports the entablature, the rind produces the fcrolls or volutes,, ■which are the great charadleriilics of this order, and the ovolo is frequently, carved. The Ionic entablature, has its architrave divided into faces ; its treeze is often made to fwell, but this is not found in the moll ancient: buildings ; and the cornice has fimpie modillions. The Ionic is an order, that Hands as a medium between the llrong and rich. It is faid the famous temple of Diana at Ephefus was of this order j at prefent it is much ufedin.- chufches y and, when juflly e.xecuted, has a very beautiful effei^l. TJiis- L A Q. 247 This order has one advantage above any of the reft, which confifts in this, that the fore and hind parts of its capital are different from its fides ; but tliis is attended with an inconvenience, when the ordonnance is to turn froni the front of the building to the fide ; to obviate which the capital may be made angular ; as is done in the temple Fortuna Virilis. Scamozzi, and' fome other modern architefts, have introduced the upper part of the Com- pofite capital, in lieu of the Ionic, imitating that of the temple of Concord,, whofe four fides are alike. To render it a little more beautiful, the volute may be made a little oval and inclining. Irregular Column, in architedlure, a column which does not de- viate from the proportions of any of the five orders, but whofe ornaments, whether in the fhaft or capital, are abfurd and ill chofen. K Keel, in naval architeifture, the principal piece of timber nrft" laid upon the blocks, which fupports the whole fabric of a fliip in the fame manner as the back-bone fuftains the body. When this cannot be had of a fufficient depth in one piece, there is a ftrong thick plank faftened to the bottom, called the falfe keel, which alfo ferves to fave the bottom of the main keel. Key, is a well-known infrrument for opening and fhutting the locks of doors, chefts, bureaus, and the like. The names of the feveral parts- of a Key are thefe : the pin-hole, drilled into the end of the fhank ; the ftep, or dap-ward; the hook- ward ; the middle- ward ; the crofs-ward^. the main-ward; the pot; the bow-ward; the bow, or handle; and the.- piece of fteel containing the wards, is called the bit of the Key. Key-Stone of an arch, or vault, that placed at the top or vertex of ani arch, to bind the two fweeps together.. Lacunar, the ancient name for what we call a foffit, when it conflfted only of compartments, funk or hollowed, without the divifion of platbands, . or fpaces between the feveraLpannels. But when they were added, it was called Laquear.. Lantern, inarchitedture, a little dome raifed over the roof of a. building, to give light, and ferve as a crowning to the fabric. Laquear, in ancient architedlure, is a term for what we exprefs by the Italian word foffir, a cieling divided into compartments, and thofe. ornamented with platbands, Wher| there were the hollow compartments only,. 248 LOG only, they called it Lacunar, from Lacus a hollow place : tut when there were thefe other ornamentSj they called it Laquear, from the rows of the platbands refembling noofes, laquei. Larmier, in architeflure, a large fquare flat and maffy member of a cornice, placed between the cymatium and the ovolo, and called alfo the Corona. Its ufe is to difperfe the water, and caufe it to fall at a diftance from the wall drop by drop. It has its nahie from Larmier hence, larme, being French for a tear. Leaves, in architeiflure, are ornaments of carving, given to the en- tablatures of the orders, and other parts of decorated buildings : they are eitl:ier twifted into feftoons, or fpread irregularly over a freeze, or other part. The ancients ufed two kinds of Leaves, the one natural, the other imagi- nary J among the natural were thofe of the laurel, palm, acanthus, and olive : but they took fuch liberties in the forms of thefe, that they might be called in a great meafure imaginary too. The introducing imaginary Leaves refleded upon their tafte, for it was an infult upon nature ; and in this very unpardonable, that nothing the art of the greateft fculptor can invent in this way will ever come up to what is afforded in nature : the va- riety of Leaves being endlefs, and their forms, in innumerable inflances, in the higheft degree elegant. We fee a great deal of this imaginary foliage in the Gothic ornaments, without wonder, becaufe thefe all was profefledly left to fancy ; but it is with concern and afto.nilhment we meet with it ia the antique. Level, among carpenters and paviours, confifts of along ruler, in the middle whereof is fitted, at right angles, another fomewhat bigger, at the 4op of which is faftened a line, which, when it hangs over a fiducial line at right angles with the bafe, fhews that the faid bafe is horizontal. Some- times this Level is all of one board. Among mafons, it is compofed of three rules, fo joined as to form an ifoceles-redangle, fomewhat like a Roman A, at the vertex whereof is fallened a thread, from which hangs a plummet that pafTes over a fiducial line, marked in the middle of the bafe, when the thing to which the Level is applied is horizontal ; but declines from the mark when the thing is lower on one fide than on the other. Lintel, in architedture, a piece of timber that lies horizontally over door-pofls and window-jambs, as- well to bear the thicknefs of the wall over it, as to bind the fides of the wall together. List, or Listell, in architedure, is a little fquare member ferving to crown, or to accompany a larger j or fometimes divide the flutings of a column. The word comes from the Italian lijiello, fignifying a little girdle, or band ; it is called alfo the fillet, and by fome a fquare. Lock,, a well known inflrument for fecuring doors, cheils, &c. and cnly to bfi opened by a key. A LUTHERM MAR 249 LuTHERN, in archlteilure, a kind of window over the cornice, in the roof of a building; {landing perpendicularly over a naked wall, and fcrving to illuminate the upper ftory. Lutherns are of various foi-ms, as f.pare, iemi-circular, round, called bulls eyes, flat arches, &c, M. Mallf.t, a kind of large wooden hammer, cfed by artificers who work with a chiffel, asfculptors, mafons, and ftone-cutters, whofe mallets are commonly round ; and by joiners, carpenters, 6cc. who work with iquare headed Mallets. Mantle, or Mantle-Tree, in architeilure, the lower part of the chimney, or that piece of timber which is laid acrofs the jaumbs, and fuf- tains the compartment of the chimney-piece. Marble, a genus of folTils, being bright and beautiful ftones, com- pofed of fmall feparate concretions, moderately hard, not giving fire with rteel, fermenting with, and foluble in acid jiienftrua, and calcining in a flight fire. The colours of Marbles being a very obvious and ftriking chara(5ler, they are arranged according to them in the following divifions. I . Of the white plain Marbles there are two forts j the Parian Marble of the ancients, and ftatuary Marble of the moderns, an extremely bright and elegant Marble ; and the Carrara Marble ; a very fine Marble, more compadl and clofe than the former, but lefs bright. 2. Of the plain yel- lowilh Marbles there is only one fort, which is a hard, pale yellow, and gloify Marble, found in many parts of Italy. 3. Of the bluilh and black Marbles there are a great many fpecies, as the Chian Marble, Bafaltes, &c. 4. Of the plain green Marbles there is only one kind, the Lacedemonian Marble of the ancients. 5. The pale coloured or whitiHi brown, com- monly called Darby Marble. 6. The green Marbles with Ihells. 7. The black Coralliode Marble, with and without fhells. 8. Of the white va- riegated Marble there are a great many fpecies, variegated with purple, brown, red, blue, &c. 9. Of the brown variegated Marbles there are likewife feveral forts, fome with red veins ; others with white, black, or brown veins, 10. Of the yellow veined and variegated Marbles fome are veined with purple, and others with blue. 1 1 . Of the black variegated Marbles, fome are veined with white, and others with blue, yellow, red, &c, 12. The green variegated Marbles are likewife diftinguithed by the -colour of their veins, i 3, The grey fpotted Marbles are variegated, Ibme with black and others with green fpots. 14. The red variegated Marble is tljeBrocatello of the Italians, with white and gold veins. Polijhing o/Marble is performed by firft rubbing them well with a free- ftone, or fand, till the firokes of the axe are worn off, then with pumice- flone, .and afterwards with emery. S iS Cohuring 250 MAR Colowing of Marble. The colouring of Marble Is a nice art, and in order to fucceed in it,, the pieces of Marble, on which the experiments are tried,^ muil be well polillied, and clear from the leaft fpot or vein. The harder the Marble is, the better it will bear the heat heceflary in the operation ; therefore, alabafler and the common foft white Marble are very improper to perform thefe operations upon. Heat is always neceffary for the opening the pores of the Marble, fo as to render it fit to receive the co- lours J but the Marble niuft never be made red-hot, for then the texture of the Marble itfelf is injured, and the colours are burnt, and lofe their beauty. Too fmall a degree of heat is as bad as too great ; for in this cafe, though the Marble receive the colour, it will not be fixed in, nor ftrike deep enough. Some colours will flrike even cold, but they are never fo. well funk in as when a juft degree of heat is ufed. The proper degree is that which, without making the Marble red, will make the liquor boil upon its furface. The menftruums ufed to ftrike in the colours, muft be varied according to the nature of the colour to be ufed. A hxivium made with horfe's or dog's urine, with four parts of quick-lime, and one part of pot aflies, is excellent for fome colours ; common ley of wood-aflies does- very well for others ; for fome, fpirit of wine is befi: ; and, for others, only liquors, or common white- wine. The colours wliich have been found to fucceed beft with the peculiar menftruums, are thefe : ftone-blue diffolved in fix times the quantity oP fpirit of wine, or of the urinous lixivium ; and that colour which the painters call litmoufe, diflblved in common ley of wood-aflies. An extrad:. of faftVon, and that colour made of buckthorn berries, and called by the. painters fap-green,. both fucceed well diffolved in urine and quick-lime,, and tolerably well in a fpirit of wine. VermilUon, and a fine powder of cochineal, fucceed alfo very well in the fame liquors. Dragon's blood, fucceeds very well in fpirit of wine, as does alfo a tincfture of logwood in the fame fpirit. Alkanet root gives a fine colour, but the only menftruum to be ufed for this is oil of turpentine : for neither fpirit of wine, nor any lixivium, Vv'illdo with it. There is another kind of fanguis draconis, cal- led Dragon's blood in tears, which, mixed with, urine alone, gives a very elegant colour.- Eefides thefe mixtures of colours and menftruums, there are fome co- lours which are to be laid on dry and unmixed. Thefe are Dragon's blood,, cf the pureft kind, for a red ; gamboge for a yellow ; green-wax for a green ; common brimftone, pitch and terpentine, for a brown colour. I'he Marble, for thefe experiments, muft be made confiderably hot, and then the colours are to be rubbed on dry in the lump. Some of thefe colours, when once given, remain immutable ; others are eafily changed c>r dt:ft.royed. Thus the red colour given by Dragon's blood, or by a j^- 2 co^a MET 251 codllon of logwood, will be wholly taken away by oil of tartar, and the polilh of the Marble not hurt by it. A fine gold colour is given in the following manner; take crude fal ar- moniac^vitrlol, and verdigreafe, of each equal quantities ; white vitriol lucceeds beft, and all mud be thoroughly mixed in fine powder. The ftaining of Marble to all the degrees of red or yellow, by folutions of dragon's blood or gamboge, may be done by reducing thefe gums to powder, and grinding them, with the fpirit of wine, in a glafs mortar ; but, for fmaller attempts, no method is fo good as the mixing a little of either of thefe powders with fpirit of wine, in a filver fpoon, and hold- ing it over burning charcoal. By this means a fine tindture will be ex- tj-adled, and, with a pencil dipped in this, thefineft traces may be made on the Marble, while cold, which, on the heating it afterwards, either on fand, or in a baker's oven, will all fink very deep and will remain perfedly dillinfl on the ftone. AriindcUiVi Marbles, ancient Marbles with a chronicle of the city of Athens infcribed on them, many years before our Saviour's birth, pre- fented to the univerfity of Oxford by Thomas, earl of Arundel, whence the name. Mason, a perfon employed under the diredion of an aixhited, in the raifing of a ftone building. Masonry, in general a branch of architefture, confifting in the art of hewing or fquaring ftones, and cutting them level or perpendicular, for the nfes of building % but in a more limited fenle, Mafoniy is the art of aflem- bling and joining ftones together with mortar. All the kinds of Mafonry now in ufe may be reduced to thefe five, y\z. bound Mafonry ; that of brick-work, where the bodies and projed:ures of tlie Itones inclofe fquare fpaces, or pannels, &c. fet with bricks ; that de- moilon, or fmall work, where the courfes are equal, v^ell fcj^uared, and their edges or beds rufiicated ; that where thecourfes are unequal, and that filled up in the middle with little ftones and mortar. Masqjjes, in architefture, certain grotefque faces, ufed to fill vacant places, as friezes, pannels of doors, keys of arches, &c. ■ Massive, among builders, an epithet given to whatever is too heavy and folid ; thus a malfive column is one too fiiort and thick for the order whofe capital it bears, and a Maffive wall is one whofe opening or lights are too fmall in proportion. Mausoleum, a magnificent tomb, or funeral monument. The word is derived from Maufolus, king of Caria, to whom Artcm-ifa, his widow, eredred a moft ftately monument, efteemed one of the wonders of the worlds and called it, from his name, Maufoleum. Metopes, in architedlure, is a name given to the fquare fpaces between the triglyphs of the Doric frieze. We have obfcrved before, that the Doric 252 MOD Doric frieze is ornamented with triglyph?, or channelled figures j thefe are placed at certain diftances one from another, and the fpaces between one and another of them are the Metopes. The diftance at v/hich the triglyphs re- gularly ftand, makes thefe fquare. They are fometimes left naked, but they were adorned among the ancients with parts of beafts, inflruments of fa- crifice, and other figures ; and they have in general fomething placed upon them in the modern v.'orks of elegance, according to the fancy of the ar- chited:. The ancient ufe of the Doric was in temples, and fome would rellrain it to them at this time, becaufe of the difficulty there is of ma- naging a frieze thus neceflarily divided in common buildings. When there is a fpace lefs than the proper Metope, as at the corner of the Doric frieze, it is called a femi- Metope, or demi-Metope. Mezanine, a kind of little ftory, called alfo an enterftole, it is placed between two principal ftories, and ferves for apartments for upper fervants. Minute, architefts exprefs by this term a thirtieth part of a femi-di- ameter of a column, that is, a fixtieth part of a diameter; and fometimes, fpeaking of weights, the twelfth part of an ounce. Modern, architedts diftinguifli buildings of former ages into three claffes,. antique, ancient, and modern ; the two firfl terms are exactly the fame in their original fenfe, but they appropriate them to different meanings. An- tique fignifies a remain that was executed when the arts were in their greatefl purity and perfedion ; and ancient, an old piece of work, but not of that perfedt truth. The word Modern is ufed as diflinguilhed from both thefe J but its fenfe is not well fixt; fome mean, by modern flrudures, thofe Gothic buildings which are fo common at this time, and, though built long fince, are Modern in comparifon of the names jufl mentioned j others, by Modern buildings, mean the Italian method, but that is only the an- tique revived. Others exprefs by this term the new whimfical ftrucflures, which have fo much of fancy and fo little judgment or tafte, that they de- ferve no name at all. It is a reiiedion upon our country to call thefe Modern, as if the general tafte were as much depraved as that of the few particular people who ereil thefe baubles. MoDiLLioNs, in architedture, are ornaments in the entablatures of the richer orders. They are little brackets, or confoles ; and their place in the entablature is under the foffit, or bottom of the drip. They ought to be fo placed that one may always be over the middle of the columns. Thefe Modillions are moft of all ufed in the Corinthian order, in which they are enriched with carvings : in the Ionic and Compofite they are more fnnple. And in the other orders they are not properly ufed at all. The word is Italian, with a different fpelling, tnodiglioni fignifying the fame thing. They feem to be introduced as fupports, but are nothing- more than ornaments. Their form is commonly that of the letter S, and fitted to the fgiSt of the cornice. The word mutule was originally ufed in M O L 1^2 'in common with inodillion, as fignifying in every refpeft tlie fame thing ; but at this time it is confined to the Doric order. The mutules in the Doric always anfwer to the triglyphs. Module, in archite(fliire, a certain meafure or bignefs, taken at plea- fare, for regulating the proportions of columns, and the fymmetry, or dilpolition of the whole building. Architedts generally chcofe the femi- diameter of the bottom of the column for their Module, and this they fubdivide into parts or minutes. The Module of Vignola, which is a femi-diameter, is divided into twelve parts in the Tufcan and Doric, and iqto efghteen for the other orders. The Module of Palladio, Scamozzi, M. Cambray, Defgodetz, Le Clerc, 6cc. which is alio equal to the femi- di.im.eter, is divided into thirty parts or minutes in all the orders. The whole height of the column is divided by fome into twenty parts for the Doric, twenty two and a half for the Ionic, twenty-five for the Ro- man, &c. and one of thefe parts is made by a Module to regulate the refh of the building by. There are two ways of determining the meafures, or proportions of buildings. The firll is by a fixed ftandard meafure, v/hich is ulually the diameter of the lower part of the column, called a Alodule, fubdivided into fixty parts, called minutes. In the fecond there are no minutes, nor any certain or ftated divifion of the Module, but it is divided occafionally into as many parts as ju.dged neceflary j thus the height of the attic bafe, which is half the Module, is divided either into three, to have the height of the plinth, or into four, for that of the greater torus j or into fix, for that of the lefier. Both thefe manners have been praftiled by the ancient as well as the modern architects ; but the fecond, which was that chiefiy uled among the ancients, is, in the opinion of M. Perault the prefei'able. As Vitruvius has lefiened his mo- dule in the Doric order, which is the diameter of the lower part of the other orders, and has reduced that great Module to a mean one, which is the femi-diameter, the Module is here reduced to the third part for the fame reafon, viz. to determine the fevcral meafures without a fraction. For in the Doric order, befides that the height of the bafe, as in the other orders, is determined by one of thofe mean Modules, the fame Module gives likevvife the height of the capital, architrave, triglyphs, and metopes. But our little Module, taken from the third of the diametei- of the lower part of the column, has ufes much more extenfivcj for by this the height of the pedeftals or columns and entablatures in all the orders are determined without a fracflion. As then the great Module or diameter of the column has fixty minutes, and tlie mean Module, or half the diameter, thirty minutes, our little Module has twenty. Mole, is amaffive work of large ilones laid in the {e.\ by means of cof- fer-dams, extending before a port, either to defend the harbour from Ttt the 25^ M O S- the impetuofity of the waves, or to prevent the paffage of fhips without leave. Mole-Head, a fort of pier, mound, or artificial iflhmus, built athwart the outer part of a little bay, and joining to fome head or ifland, to form a retreat for fliipping. MoNOPTERE, in architedure, a kind of temple, round, and without walls, having a dome fupported by columns. Monument, in architedlnre, a building deftined to preferve the me- mory, &c. of the perfon who raifed it, or for whom it was raifed j fuch are a triumphal arch, a maufoleum, a pyramid, &c. Moor-Stone, a valuable ftonc much ufed in the coarfer works of the prefent builders ; being truly a white granite, of a marbly texture. Mortise, or Mortoise, in carpentry, &c. a kind of joint, wherein a hole of a certain depth is made in a piece of timber, which is to receive another piece called a tenow. Mosaic-Work, is an affemblage of little pieces of glafs, marble, precious flones, &c. of various colours cut fquare, and cemented on a ground of ftucco, in fuch a manner as to imitate the colours and degra- dations of painting. The materials ufed for thefe works are httle pieces of glafs of all the different fhades in every tint or colour, like thofe of the fine EngliQi worlted ufed in needle-work. The glafs is firfl call into thin cakes, which are afterwards cut into long pieces of a different thicknefs. Many of the pieces ufed in the works on roofs and ceilings,, which are confequently i'esn only at a great diilance, appear to be a. finger's breadth ; but the finer works confifts only of glafs pins, if we may make ule of that exprefHon, not thicker than a common fewing needle,, lb that a portrait of fx)ur feet fquare Ihall take up tvvo millions of fuch. pins or fluds. Thefe pins are fo clofely joined together, that after the. piece is polifhed, which is done in the fame manner as looking-glafTes are poliflied, it can hardly be difcerned to be an arrangement of an infi- nite number of particles of glafs ; but rather looks like a pidure paint- ed with the fineft colours, with cryftal placed before it. The ground: in which thefe vitreous pieces are inlaid, is a pafle, compounded of calcined marble, fine fand, gum tragacanth, whites of eggs, and oil. It is at firft fo foft that the pieces are eafily inferted, and upon an over- fight may be taken out again, and the palle new moulded for the ad-- mifiion of other pins or fluds ; but by degrees it grows as hard as a flone, fo that no impreflion can be made on the work. This pafle is fpread within a wooden frame, which, for large pieces, mufl not be lefs than a foot in breadth and thicknefs. This frame is fafbened with brafs tacks to a plate of the lame metal, or to a flone flab ; and as in capital pieces, which are often tv.enty feet by fifteen .; this pafle-ground mufl be above thi-ee quarters of a foot deep, and the pins or fluds as long, it may M O S 255 may eafily be conceived of what weight fuch a piece mufl be. The pieces defigned for roofs, or any diftant place, are not polillied ; but in the altar- pieces,, &c. nothing is wanting to give them themoft beautiful and fplen- did appearance. A piece of about eighty feet fquare, if performed with tolerable care and delicacy, will employ eight artifts for the fpace cf two years. The ftuds of the feveral colours lie ready before the artifts in cafes, as the letters are laid before the compoiitors in a printing-houfe : and fuch is their accuracy in imitating the fineft ftrokes of the pencil, that the only apparent difl'erence betwixt the original painting and fuch- a. copy is, that the latter has a much finer lulire, and the colours are more vivid. Method of performing Mosaic-Work of marble and precious f ones.— ^ The ground of Mofaic-works wholly marble, is ufually a maffive marble,, either white or black. On this ground the delign is cut with a chifTel, after it has been firft calqued. After it has been cut of aconfiderable depth, i. e. an inch or more, the cavities are filled up with marble of a proper colour, firfl fafhioned according to the defign, and reduced to the thicknefs of the indentures with various inftruments. To make the pieces thus inferted into the indentures cleave faft, whofe feveral colours are to imitate thole of defign, they ufeaflucco compofed of lime and marble-dufl 3 or a kind of maftic, which is prepared by each workman after a different manner pecu- liar to himfelf. The figures being marked out, the painter or fculptor himfelf draws with a pencil the colours of the figures, not determined by the ground,, and in the fame manner makes flrokes or hatchings in the place where fhadows are to be ; and after he has engraven with the chiffel all the flrokes thus drawn, he fills them up with a black maflic, compofed partly of Burgundy-pitch poured on hot ; taking off afterwards what is fuperfluous with a piece of foft flone or brick, which, together with water and beaten cement, takes away the maftic, poliflies the marble, and renders the whole foeven, that one would imagine it only confifled of one- piece. This is the kind of Mofaic-work that is feen in the pompous church of the Invalids at Paris, and the fine chapel at Verfailles, with which fome- entire apartments of that palace are incruftated. As for Mofaic-work of precious flones, other and finer inflruments are required than thofe ufed in marble ; as drills, v/heels, &c. ufed by lapidaries and engravers on fione. As none but the richell marbles and. ftones enter this work,, to make them go the further they are fawn into tlie thinneft leaves imaginable, fcarce exceeding half a line in thicknefs j; the block to be fawn is faflened firmly with cords on the bench, and only railed a little on a piece of wood, one or two inches high. Two iron pins, which are on one fide the block, and which ferve to fallen it, a are, 256 M O U are put into a vice contrived for the purpofe, and with a kind of fav/ or bow, made of fine brafs wire, bent on a piece of fpongy wood, together -with emery ileeped in water ; the leaf is gradually falhioned by following the flroke of the delign made on paper, and glued on the piece. When theie are pieces enough faftened to form an entire flower, or feme part of the delign, they are applied to the ground. The ground which fupports this Mofaic-work, is ufually of free-ftone. The matter with which the ftones are joined together, is a maftic, or kind of ftucco, laid very thin on the leaves as they are falhioned ; and this being done, the leaves are applied with plyers. If any contour, or lide of a leaf be not either fquared or rounded fuf- ficiently, fo as to fit the place evacflly into which it is to be inverted, when it is too large, it is to brought down with a brafs file or rafp ; and if it be too little it is managed with a drill and other inftruments ufed by la- pidaries. Moiaic-work of marble is ufed in large works, as in pavements of churches, bafilicks, and palaces ; and in the incruftation and vaneering of the walls of the fame edifices. As for that of precious ftones, it is only ufed in fmall works, as orna- ments for altar-pieces, tables for rich cabinets, precious ftones being fo very dear. Mosque, is a temple or place of religious worfliip, among the Mahom- metans. All Mofques are Iquare buildings, generally built with ftone; be- fore the chief gate there is a fquare court, paved with white marble, and low galleries round it, whofe roof is fupported by marble pillars. In thefe galleries the Turks wafti themfelves before they go into the Mofque. About every Mofque there are fix high towers, called minarets, each of wliich has three little open galleries, one above another ; thefe tov-'ers, as well as the Mofques, are covered with lead, and adorned with gilciing and other ornaments ; and from thence i iftead of a bell, the people are called to prayer by certain officers appo'nt J for that purpofe. Mould, or Mold, in the mechanic arts, &;c. a cavity cut with a de- fign to give its form or impreffion to feme fofter matter applied therein, of great uie in fculpture, foundery, &c. Mouldings, in architefiure, projedlures be}'Dnd the naked wall, co- lumn, wainicot, &c. the affemblage of which forms corniches, door-cafes, and other decorations of architecfture. Some Mouldings are fquare, ofliers round, fome are ftraight, others curved, &c. and Ibme are plain, others carved, or adorned with fculpture, either hollowed or in relievo , fome again are crowned with a fillet, others are without, as the doucine, talon, ovolo, torus, fcotia, aftragal, gula, corona, &c. A doucine is the cymatium, or that in which the hollow part has the • greateft projedure; the talon is the ogee, in wiiich the fwellin^ part has ♦ the N A I 257 the greateiT: prqjeftion. The ovolo is a quarter round fwelh'ng. The ca- vetto is a quarter round hollowed ; the aftragal is fmall and round, and has ufually its fillet j thedentell reprefents teeth ; the plinth is a plain fquared furface, whofe ufe is generally to lupport the bafe of a column. Cornices, door-cafes, and many other ornamental pieces, are formed out of a compofitlon of Mouldings. All Mouldings in regular architec- ture may be reduced to three kinds, the rounded, the fquare, and the curved ; and from a combination of thefe which are the principal ones, and an occafional mixture of the others, may be formed a great variety of beautiful pieces ; but in Gothic architefture, we fee fancy in- dulged at an extravagant rate to fuperfede the ufe of the ancient and natural Mouldings. MuLLER, a ftone flat and even at the bottom, but round a-top, ufed for grinding of matters on a marble. The apothecaries ufe Mullers to pre- pare fome of their teftaceous powders, and painters for their colours, either dry or in oil. MuNiMENT-HousF, a little ftrong room in a cathedral, college, or univerfity, deftined for keeping the feal, charters, &c. of fuch cathedral, college, &c. Mural Arch, a wall, or walled arch, placed exadlly in the plane of the meridian, for fixing a large quadrant, fextant, or other inflrument, in order to obferve the meridian altitudes of the heavenly bodies. Mutules, a term ufed by fome to exprefs what are more commonly called modillions, which are brackets or confoles. Others appropriate the word Mutule to thefe ornaments in the Doric order, and call the others only modillions. Nails, In building, &c. fmall fpikes of iron, brafs. Sec. which being driven into wood, ferve to bind fevcral pieces together, or to fafien fome- thing upon them. The feveral forts of Nails are very numerous ; as I. Back and bottom nails, which are made with flat flianks to hold fafl and not open the wood. - 2. Clamp-nails, for fiftening the clamps in building, &c. 3. Clafp-nails, whofe heads clafping and flicking into the wood, render the work finooth, fo as to adniit a plane over it. 4. Clench-nails, ufed by boat and barge builders, and proper for any boarded buildings tr^at are to be taken down ; becaufe they will drive without fplitting the wood, and draw without breaking ; of thefe there are many forts. 5. Clout-nails, for nailing on Clouts to axle trees. 6. Deck-nails, for faftening of Decks in fliips, doubling of fliip- ping, and floors laid with planks, j. Dog-nails, for fafi:ening of hinges on doors, &c. 8. Flat points, much ufed in ihipping, and are proper U u u where 2s^ NIC where there is occafion to draw and hold fafl, and no conveniency of clenching, 9. Jobent Nails, for nailing thin plates of iron to wood, as fmall hinges on cup-board-doors, &c. 10. Lead Nails, for nailing lead, leather, and canvas to hard wood. 11. Port-Nails, for nailing hinges to the ports of fhips. 12. Pound Nails, which are four fquare, and are much ufed in Eifex, Norfolk and Suffolic, and fcarce any thing elfe ex- cept for p.deing. 13. Ribbing Nails, principally ufed in Ihip building, for faftening the ribs of fliips in their places. 14. Rofe Nails, which are drawn four fquare in the Ihank, and commonly in a round tool, as all common two-penny Nails are ; in fome countries all the larger fort of Nails are made of this fhape. 15. Rother Nails, which have a full head, and are chiefly ufed in faftening rother-irons to Ihips. 16. Round-head Nails, for faftening on hinges ; or for any other ufe where a neat head is required; thefe are of feveral forts. 17. Scupper Nails, which have a broad head, and are ufed for faftening leather and canvas to wood. 18- Sharp Nails, thefe hnve fliarp points and flat thanks, and are much ufed, efpecially in the Weft-Indies, for nailing foft wood, 19. Sheathing- Nails, for faftening flieathing-boards to fliips. 20. Square-Nails, which are ufed for hard wood, and nailing up wall fruit. 2 1 . Tacks, the fmal- left of which ferve to faften paper to wood ; the middling for wool- cards, &c, and the larger for uphblllerers and pumps. Nails are faid to be toughned when too brittle, by heating them in a fire-fliovel, and putting fome tallow or greafe among them. Nails are fold at fix fcore to the hundred : in lathii-tg, five hundred are ufually allowed to a bundle of five feet laths, and fix hundred to a bundle of fix feet laths ; in floor- ing, two hundred are fnfficient for a Iquare of flooring. Naked, is a term ufed to exprefs the plain furface of a wall, column,, or other part of a building, in diifincLion from the ornaments. Thus the Naked of a wall is the flat plain furface of the wall that receives the mouldings j and the Naked of a column is its bare furface. Nave, in architecture, the body of a church, where the people are- difpofed, reaching from the ballufter, or rail of the choir, to the chief dooro.. Newel, in architedlure, the upright poft which a pair of winding ftairs turn about. Niche, in architedlure, a hollow funk into a wall, for the commodi- ous and agreeable placing of a ftatue. The ordinary proportion of a Niche is to have two circles in height and one in width; but M. Le Clerc makes their height fomething more, the excefs being to compenfate for the height of the pedeltal or the ftatue. The hollow is femi-circular at bottom, that is, in its plan ; and at top it terminate in a kind of canopy. Niches have frequently an impoft, and an archivolt or head-band, and the canopy wrought and enriched in the manner of a fliell. The breadth of the archivolt may be made equal to a fixth or feventh part of the Niche,_ and O R D 259 and the height of the impofl to a fifth or fixth part of the fame ; and the impoft and archivolt ought to confift of fuch mouldings as have feme rela- tion to the architefture of the place. Niches are fometimes made-\vith ruftic-work, fometimes with fliell-wdrk, and fometimes of cradle or ar- bour-work. Niches are fometimes made fquare, but thefe want all the beauty of the others. Nudities, in painting and fculpture, thofe parts of an human figure not covered with any drapery, or thofe parts where the carnation appears. o. Obelisk, in architefture, a truncated quadrangular, and. flender pyra- mid, raifed as an ornament, and frequently charged either witii infcriptions or hieroglyphics. Obelifks appear to be of very great antiquity, and to be firll: raifed to tranfmit to poflerity precepts of philofophy, which were cut in hieroglyphical charad;ers ; afterwards they were ufed to immortalize the great adlions of heroes, and the memory of perfons beloved. The firft Obeliilc mentioned in hiftory was that of Ramefes, king of Egypt, in the time of the Trojan war, which was forty cubits high. Phius, another king of Egypt, raifed one of forty-five cubits ; and Ptolemy Philadelphus, another of eighty-eight cubits, in memory of Arfinoe. Auguftus erefted one at Rome in the Campus Martins, which ferved to mark the hours on an horizontal dial, drawn on the pavement. They were called by the Egyptian priefts the fingers of the fun, becaufe they were made in Egypt, alfo to ferve as ftyles, or gnomons, to mark the hours on the ground.. The Arabs ftill call them Pharoah's needles, whence Italians call them aguglia, and the French aiguilles. The proportions in the height and thicknefs are nearly the fame in all Obelifks ; their height being nine, or nine and a half, and fometimes ten times their thicknefs ■ and their diameter at the top never lefs than half, and never greater than three-fourths of that at the bottom. Office, in architefture, in the plural denotes all the apartments ap- pointed for neceffary occafions of a palace or great houfe as kitchens, pan- tries, confedlionaries, &c. Ogee, or as it is fometimes written O. G. a moulding, part fwelling and part hollowed, fo that its outlines refembles a wave. When placed with the hollow part upward, it is called the upright Ogee, cima refta, or cy- mafium ; when the fwelling part is upwards, it is called an inverted Ogee, SI flat, and cima inverfa. Order, a column entire, confining of bafe, fhaft, capital, and enta- blature, and proportioned to the ufe or fervice for v/hich it is intended. This is what is properly called an Order of archi tenure, and the feveral 2 vifes 26o O R D ufes and fervices requiring fome difi:in6tion in ftrength, there have been con- trived five kinds of thefe columns, three originally by the Greeks, the Doric, Ionic, and Corinthian, and two added by the Romans, the Tufcan, and the Compofite. Each of thefe has its ornaments as well as general fabric proportioned to its ftrength and ufe ; and thefe are the five Orders, the proper underftanding of which is the great article in the elegance of build- ing. Beginning from the plaineft and the ftrongeft, thefe are reckoned thus: I. The Tufcan. 2. The Doric. 3. The Ionic. 4. The Corin- thian j and 5. The Compofite. The Tufcan is the moil fimple and ftrong, the column has feven diame- ters in height, and the capital, bafe, and entablature, have no ornaments, and but few mouldings. The Doric has the column feven and a half or eight diameters high ; it has no ornaments on the bafe or capital, but its frieze is decorated with channelled figures, called triglyphs, placed at fuch a diftance as to leave fquare fpaces between them. Thefe fquare fpaces are called metopes, and are fometimes plain, and fometimes ornamented with heads of beafls, and other figures. The Ionic order has the column nine diameters in height ; its capital has volutes, which are a kind of fcrolls, and there are plain modillions in the cornice. The Corinthian order has its column nine diameters and a half high ; its capital is ornamented with two rows of leaves, and among thefe rife up ftalks which curl round under the abacus, and reprefent, in fome meafure, the vo- lutes of the Ionic, but they are fmaller and more numerous; and the enta- blature of this order has modillions under the cornice. The Compofite order has its column half a diameter higher than the Corinthian, that is, ten diameters, but fome make it more, and fome lefs; and its capital has leaves, and above tliem the volutes of the Ionic order. Its cornice has modilhons. Thefe are the five great Orders of architeones, vv'as at the pains of finding out the artitt who did the bufinefs ; and on his lefufing to part with the lecret on any terms, this author, with Albert Gunter, a Saxon, endeavoured to find it oui; ; in which they fucceeded at length very well. The method is thisj take T R A 2Pf take aqua fortis and aqua regia of ejch two (Unccs, fal armoniac one ounce, Ipirit of wine two drams, about twenty-lix grains of gold, and two drams of pure filver ; let the filver be calcined and put into a vial, and pour upon it the aqua fortis; let this rtand for foms time, then eva- porate it, and the remainder will firll appear of a blui, and afterwards of a black colour. Then put the gold into ^njther vial, p^ur the aqua regia upon ir, and vvhen it is dillo'ved, evaporate it as the former. Then put the fpirit of wine upon the fal armoniac, and let it be evapo- rated in the fame manner. All the remainders,- and many others made in the fame manner from other metals, dilfolved in their proper acid menflrua, are to be kept feparate, and ufed with a pencil on the marble. Thefe will penetrate without the Iccifl: affiltance of heat, and the fi jurcs being traced with a pencil on the marble, the feveral parts are to be touched ever with the proper colours, and this renewed dailv till the co- lours have penetrated to thedefired depth into the (tcne. After thi', the mafs may be cut into thin plates, and eveiy one of them will have the figure exaT./r:K)f Volute, in architcfture, the name of a 'fcroll, which is the diftin- gui(hing charadcr ot the lo: ic capital. ]t is fuppoled to reprelent the balk ot a tree, which is laid up n the rim of a velfel, and as it has dried has curl.d ai>d twilled itfclf into a kind of fpiral fcroll. There are a lort ot V^ luieb alio in the Corinthian capital, but they are fmaller and more numerous than in the Ionic ; and in the Compofite capital tbele large*nd proper Volutes of the Ionic arc added. G g g g Itv J9^ W A L In the moft antique Ionic Volutes, the lift or edge throughout all the ,circumvolutions, is in the fame line or plane; and in feme they projedlj on fome they are oval, and in others the canal of one circumvolution is (ietached from the lift of another by a viicuity; in others the round is parallel to the abacus, and fprings out from behind the flower thereof; and in fome it feems to fpring out of the vafe from behind the ovum, and rifes to the abacus. The Volute has by fome been fuppofed to reprefent the horn of a ram, and by others the curl of a womui's hair; but the moft natural refcm- blance is that of the bark, and that is moft in the charafter of the an- tient defigns in architedure. ConTolcs, modiillons, and fome other or- nament?, have fometimes a fort of Volute. Upright, in architedlure, a reprelentation oi- draught of the front of a building, called alfo an elevation cr orthography. Urella, in architedure, the little fpiral twift or volute that is under the flower in the Corinthian capital, it is formed by a twifted ftallc of the acanthus, and is more commonly the helix, fometimes the caulicole. Urn, in architedture, a kind of vafe, ferving to crown and decorate baluftrades, and other ornamental parts of buildings. Urn is too com- monly ufed as of the fame meaning with vafe, but it properly denotes a diftindt kind and form. The Urn ftiould be low and wide, and is fitteft for grottos and fountains. Urns are alio ufed on tombs, for which pur- pofe they are generally enriched with fculpture, and are diftinguiftied by the name of funeral Urns, The ancients preferved tKe aflaes of the burnt bodies in urns, and thence has arifeh this cuftom of uhhg Urns on mo- numents and maufoleums. For which reafon they were called cineraria, and urns cinerarias, and were placed fometimes under the tomb-ftone whereon the epitaph was cut, and fometimes in vaults in their own houfes. Urns were alfo ufed at their facrifices to put liquid things m. W. Wainscot, in building, the timber work that ferves to line the walls of a room, being ulually made in pannel^, agi^ pajnted* to i^rve inftead of hangings. : -,>! -.'!■ i Wall, in architedure, the principal part of a building, as ferving both to inclofe it, and fupport the roof, floors, &c. Nothing is of lo much confequence as the raiUng them in a workman-like manner. The foundation walls are to diminish in thicknefs as they ar« wrought up, and that diminution ftiould be continued to the top of, the building, the workman ftill taking care to keep the center of the Wall all the way ilrait from the bottom of the foundation. Walls W A L 299 Walls in this country are principally built of thefe two materials, brick or ftone, and in building about London brick is the mo-H: common. We fee» in feme parts of the kingdom. Walls built of flints cut into a tolerably even form in a very furprifmg m.inner. There are at this time fome fine Walls ftanding of this material in the city of Norwich, and it was introduced in the late old gate at Whitehall, and fome of the adjoining buildings of the fame period. This was an art unknown to the ancients, and it is loft again at this timej but it was ftrong and beautiful. In the Walls of common houfes, which are of brick, the general diminution from the bottom to the top, is one half the thicknefs at the bottom ; the beginning is two bricks, then a brick and a half, and at the upper part one brick, thicknefs. In larger edifices, the Walls are made prcportionably thicker, but the dimenfion is preferved in much the fame manner. Some Walls are plain and continued, .others made with intermiflions. When a building is to be ftrong, the 'Walls muft have a proportionable thicknefs. We have faid that they need not be all the way of an equal diameter; the decreafe of tliis is what we call the di- minution of a Wall, and we have obferved already, that this diminution fhou'd be made equal on each fide, that the load may be exadly in the middle. The Wall fhould be carried up all the way exadlly perpendi- cular to the grand-work ; for the right angle it makes in this is the foundation of ftrength and firmnefs. If the Wall be compofed of two kinds of materials, as ftone and brick, the maflieft and heavieft are to be ufed in the loweft part, as being fitter to bear than to be born, and the lightcft at the top. The diniinifliing in thicknefs as the Wall rifes, faves both weight and expence ; but it is not abfolutely necelfary, for if the Wall were carried up in a perfcdl perpendicular from bottom to top, and all the way of the fame thicknefs, it would not for that reafon be lefs ftrong. In this cafe the keeping the perpendicular perfedl would be the great difficulty and the great article of merit. We find the ancients were able to do this ; for we fee in the remains of their works. Walls thus carried up to an exorbitant height ; but our arch itetfls are more ready to be afloniflied and admire, than to ftudy and imitate them. The great rule for the thicknefs of the VVall in all buildings is, that it be proportioned to the weight it is to fupport. This is tJ be carefully romputed, and there will be no danger of the ftrength of the edifice ; for the great occafion of that fault is the not obferving this proportion. A Wall that ftands alone is its own burthen and fuppott j the higher parts prt-ts upon the lower, and the lower bear up the higaer; this is all, and the ftrudture of it is therefore plain and eafy. In a larger buildirig the rches, roofs and the floor, are the burthen i the WalU aie the iupport : let '300 W A L let the architedl therefore compute the weight of the one according to his pliin, and to that proportion the ftrength of the other. J he thick Wall? that bear diredly upon their foundations prels from top to bottom ^j the arches prefs lide-wwys, and to know how much, we muft mcafure their convexity. The floors and the roof have a grtat preflure perpen- dicularly, and a little obliquely : all this mull be carefully conlidercd, and upon this depends the computation of the general load, and of the necellary proportioned thicknefsof the Walls. The ftrength of a build- ing depends upon the force of its fupports : and the great art on this head is, that of giving a plain wall the utmoll flrength of which it is capable. We have adviled the young architecl to be careful in this computa- tion, that he may know what flrength his Walls ought to have, iur it is as eafy to make them too thick as too thin, and either extreme is equally unworthy of a good builder ; too much thicknels in Walls not only is the cxptpce of a great deal of ueedlets money, but it gives the edifice a very heavy afpc6t. The great art is to join flrefigth and deli- cacy. We fee the fonrer confulted in many of our modern I uildings at the expence of the latter. The ancients had an art in joining thcfe that we have loft. They were fparing of ftone, but they never grudged iron work, and b) the means of that alliftance and of a perfedf truth in their perpendicul irs, they have left us n^odtls we defpair cf copying. Our houfes tumble down after a few years for want of ftrength ; and we have confecrattd the heavinefs of our work in moft of the m.dem churches. There is one farther particular which rtgaros ftrength .n the ftrudure of a plain W all, and that is the fortifyirg the angles. This is bcft done with gocd 0( ne on each fide, which gives not only a great deal of ftrength but a great deal of beauty. A Wall ihct is raifed over arcnes and pil- lars, provided they be judicioufly direftcd, and the work carried on in the fame manner, ftands as firm as one that is begun from a plain founduion. Pihillers properly applied area very great ftrcngthening to Walls j their bell diftance is about every twenty foot, and they Ihould rile live or fix inches trom the naked of the Wall. A much (lighter WaJ of brick, with this aliiliance, is ftronger than a heavier and maffier built plain. In brick Walls of every kit^d, it is an exceeding addition to their ftrength to lay fome chief courles of a larger and haroer matter, for thefe ferve like finewb to kttp all the reft togeiher, and are of very gicut ufe when a Wall t .ippeiis to fink more on one nde than another. In the m. il perfeft way ot forming the diminution of Walls, the middle of the thinnell pait being dircftiy over the midaie of the thich.cit, tiie W A L 301 the whole is of a pyramiJal form ; but when one fide of the wall muft of neceffity be perpendicular and plain, it mull be the inner, for the fake of the floors and crofs walls. The diminilhed part of the outfide may be covered in this cafe with a fafcia or cornice, which will be at once a ftrength and ornament. As the openings in a wall are all weakenings, and the corners require to be the ftrongeft parts, there never Ihould be a window very near a corner. Properly, there Hiould always be at leaft the fpace of a breadth of the opening firm to the corner. This is the general idea of a wall, and, according to thefe principles, it may be raifed of any needful height, and for the kipport of any weight above; and the young arcf)itedt being thus acquainted with the form, we fliall next lead him to the con- fideration of its conflrudic)n of whatfoever materials. The ancients ereded their walls fomeiimes of ftone and fometimes of brick, as we do ^ and by the remains that are yet extant of the fcveral kinds, we find they had various ways of conftrufting them. At prefent, archited:ure in this, as in its other branches, is reduced into a much nar- rower compafs than it has been in earlier times ; but as it is not impof- fible to improve upon the prefent pradice, and as the works of the an- cients are in all relpedts the beft models we can follow in the attempts of improvement, we Hiall here give a fhort recital of their feveral manners of conftrueling them, before we mention thofe of our own time. Their chequer work, or reticulated wall, was at one lime famous, but was looner out of ufe than the others. This had corners of orick, and courfts of brick to bind the whole; there were about three courfes at every two feet and halt; the inward part of the red: was made of ce- ment, and the facing was chequered. Their common brick walls were made with the two fides of good bricks, and the middle was filled up with mortar and brick-bats rammed together. rheir cement walls were compofed of cement with pebbles and earth, laid in a rough manner, fometimes with, and fometimes without mortar, but the corners were ftrengthened with brick or ftone, and at every two feet height there ran courfes of brick- work, to bind and ll^rencrthen them. Their ruftic walls were built with rough and irregular ftones of vari- ous fliapes and fizes, which they laid together as evenly as they could by nieansof a leaden rule; this being bent according to the place where flone was to be laid, ihewed how it was to be formed and placed. Their fquared walls were made of larger and fmaller ftones regularly cut and fquared, and laid with great beauty. A courfe of larger and a courfe of fmaller ufually were laid over one another. This was a wall of great beauty and grcv^t ftrenclh. H h h h Their 302 W A L Their cofFer-woik walls were made of rough and ragged Hones, wiih a ilrong mortar. Thefe had their nanies from the manner of working them. They made a kind of oblong coffers of boards dillaiit by the in- tended tbicknefs of the wall, and into thefe they threw ragged ftoncs, ce- ment, and earth at random ; but they began with a courfe of brick- work, and made courfcs al(o between. The mortar we ufe at this time would not hohl fuch materials together in a wall ; but we have before obferved, that the ancients were much more careful both in the mate- rials and manner of working it ; we fee an inftance of the effttt of that care and pains, for there are walls of this ftrudure in which no trowel was ufed, but the force of the mortar held the moft uneven ftones, and they are very flrong after two thoufand years. Tliere occur alfo remains of a confiderable antiquity, in which we fee a kind of coffer- work, of a folid fubrtance, with this rough mixture within, the coffer- work being the effential part of the wall j in thefe two rows of good free ftone were laid at a confiderable diflance, and there ran crofs-bars of the fame ffone from fpace to fpace between them ; the refl: of the inner fpace was vacant in form of great fquare coffers, and they filled up with rough flones and mortar poured in together, which hardening, with the retf became a folid part of the wall. Vitruvius faw the objedion to the chequered wall, that it would be more liable to accidents than the others; and it was found fo, and there- fore difufed. The double brick walls with cement and brick-bats between, are ex- tremely ffrong and fit lor great buildings ; we lee remains of them in the rotunda and in the baths of Dioclefiun. We have examples of the ce- ment walls in the amphitheatre of Verona: the walls of the prasnefle afford an inftance of the rullic, and they paved their ftreets in the fame manner. The fquare flone walls are to be feen in remains about the temple of Auguftus, alfo of the antique coffer-work kind, where the face and crofs work is Hone, and the filling up of the coffers, mortar, and rough flones. Inigo Jones obferves, that he had feen the ruflic of the wail of the ancients in a houfe going to Naples, and that it looked very well, and that the fqu:!red flone wail marie of ifones of different bignelles has a grand look in many of the ancient buildings. We lee in ail thefe with what knowledge both of the nature of materials and the manner of dif- pofir.g them, the ancients built their wafs : what lire ngih, lolidity and beauty. We have all their materials, we fhall next obferve in what man- ner we employ them. We build walls of part flones, or entire bricks, and fomctimes face thfm with f.ewn flone, or cover them in part with plailler wrought into rcftmblance of fuch a ffone covering. When brick walls fland finale we W A L 3^3 we frequently cope or cover them at the top with ftone ; but in exa- mining through the whole courfe of the proceeding, we fliall find that we have neither the ftrength, beauty, nor variety of the ancients in this great part of architecture. We rarely fee inftances of walls of entire ftone rough or wrought without any facing of another kind, and it is only in the moft expenfive of our buildings the others make any tolerable figure; what we commonly fee about houfes is a facing of cut (lone over a wall of ordinary brick-work, better or v/orfe j and as to brick walls, inftead of the doul)le facing of the ancients, which was filled up between with a rougher ftuff, our walls are ufually faced with good brick on the outfide, and wrought up a coarfer kind inwardly, the inner fur- face not being feen when the building is finiflied. In regard to the manner of conftrudting a brick-wall, we are to cau- tion the young architedl that in fummer he lay the bricks as wet, and in winter as dry as he can ; for this is the way to make them bind the better with the mortar. In fummer as foon as they are laid, they are to be covered up, to prevent their drying too faft, the mortar in that cafe lofing half its binding quality j and, for the fame reafon, they are to be covered yet more carefully in winter, for rain is a great enemy to the ftrength of mortar, and froft is worfe. In all cafes let him take care that the angles of his walls be well united together, for if the ad- joining walls be not wrought up at the fame time, they never clofe fo well. Finally, that all the parts of the building where there are walls to be raifed and finidied at the fame time, becaufe then they fettle equally every where, and there are none of thofe cracks and clefts, which are fo great a blemhh in the building and fcandal to the builder. Treating of walls, we fhould not omit to mention thole inferior kinds which have been once much ufed, and are in fome places to be met with now ; for though brick and ftone are the general walls at this time, they do not utterly exclude all others. In framed timber houfes, there sre fcmetimes ulcd what may be called walls of lath and plaifter; and in fmall buildings made altogether of wood, there are what may be cal- led boarded walls. The plailfer walls are chiefly ufed in ordinary tim- ber buildings : they are compofed of loam or coarfe mortar fpread over the laihirig, which is to continue from beam to beam, and the whole is covered afterwards v^ith a fine mortar. Sometimes the timber work is left naked, foinetimes the whole is covered with lathing, and ti;en with loam and mortar; this is the handfomefl: manner of doin2 it, and frequently in this way of ufing it is rough call: over, and while clean makes a pretty appearance. In what are called boarded walls, the great care is to iecure them very well by painting without, and by plaifteriug within, in which caie they will endure a very confiderable time, aisd will be no mure in danger of accidents by fire than other materials. Thefe 30 1- WAT Thefe are a very inferior kind, and only fit for meaner ptirpofts, hat in a general account of walls it would have been wrong to omit naming thrm. Wefliall from thefe proceed to the conlidcr.uion of thofc nioft expcnfive and elegant walls, which we raifc? of iievvn ftune for churches and other elegant buildings. In thefe the better the flone be wrought the fm;d!tr will be the joints, and this is a creat excellence in that kind of building. We fee the ancients have been fo accurate in the cutting of their (lone on ihefe occafions, that in the remains of many of their great buildings we can Icarce perceive a joint, but the whole looks as if of one entire reck wrought to that exadtnels. I'here is indeed thus much to be faid on this head, that they in reality did work down the iaces of their ftones after their walls were ereded, their whole care before being to cut the fquares that were to join with a pcrfed exadncfs. We fee proofs that this was their manner of working .among their re- mains ; in fome the faces of the ifones were yet rougli as they were laid, and in others the very marks of the tools Chew how they were wrought. In buildings of valV extent and expence, they lometimes wrought only the impofls of arches, the capitals and cornices, leaving the reft rough as they laid it in. This was thtir manner of executing v.hat we call ruflic, in diflindlion from thofe walls they finiflied up in every pait. Tliere is nothing into the fpirit of which we have lefs entered than the ruftic of the ancients in their walls. We fee they have done it, and therefore we conclude it to be right; but we Ihould examine why they did it, and conform ourfelves to the fame condudt. They al- ways ufed this lorm in their largefl buildings, we have therefore no au- thority from them for uli ng it in fmall ones. In our flone walls for elegant edifices this Imallnefs of the joints fhould be our great concern, and to this end the fides of the flone where they are to join cannot be wrought with too much care and exaitne/s. The ufe of thin flieet-lead it, alfu excellent; and upon the whole, as it concerns only buildings of great expence, it is an article in which the price of workmandiip never fliould be fpared. Of all materials for building walls for fru.t-trees, brick is the bed, it being not only the hamlfomel'l:, but the warmelf and kindefh for the ripen- ing of fruit, and affording the bell conveiiiency for nailing, as fmaller nails will lerve in brick than will in Hone walls, where the joints are larger; and if the walls are coped with free flone, and flone pilaf- ters or columns at proper diliances, to feparate the trees, and break off the force of the winds, they are very beautiful, and the moft pro- fitable walls of any others. Water-Table, in architedlure, a fort of a ledge left in flone or brick-walls, about eighteen or twenty inches f'lom the ground, from wliich place the thickncfs of the wall begins to abate. Wat£R- X Y S Water-Whkel, is an engine for raifing water in great quantities out of a deep well. Water- vVoRKS, in general, denote all manner of machines moved by, or employed jn raifing or fuftaining water, in wlich i'enk, water- mills of all kinds, fluiccs, aquc^duds, &c. may be called Water-work?.

At the Earneft Requeft of manv of our StTB<:cRiB''ns, we (hall give a complete A B S T K A C I ot the ACT OF PARLIAMENT, OF THE FOURTEENTH, OF GEORGE THE THIRD, FOR REGULATING BUILDINGS AND PARTY-WALLS, &c. THE Preamble to the Adl of the 14th of George III. recites. That the Aifl made in the i^th year of the fame reign, for the purpofe of regulating Buildings and Party-walls, &.c hath been found iniufficient to anlvver the good purpofes intended thereby; and there- fore that it may tend to the Safety of the inhabitants, and prevent greater inconveniences to Builders, and workmen employed in Build- ings the prefent Ad has been made, and began to take effedl on the 24th of June, 1774. This prefent Aft is made to repeal entirely the faid Adl of the 12th of George the Third ; and alfo fo much of all other Afts whatever as re- lates to the regulation of Buildings and Party-walls. All irregular eredlions whatever built fince the paffing the faid Adl of the 12th of George the Third, and contrary thereto, (except where pro- ftcuticns have been commenced, and the penalties paid^ are to be alter- ed and made in every refpedt conformable to the feveral regulations con- tained in that of the 14th. The King's palaces, or any building in the pofleffion of himfelf, his heirs, or fucctflirs, or employed for his ufe ; alfo the Queen's palace, or any building in her pofleffion, or employed for her ufe, are exempted by this prefent Ad: trom the feveral regulations therein contained. By the iaid Ad, all other buildings whatever now built, or hereafter to be built, are by the Ad divided into feven different rates or clafles. We fhall now proceed to the feveral regulations contained in the Ad, which we are enjoined to ojjferve. Kkkk RATES ( 3oS ) RATES OF BUILDINGS. Ill what Manner determined. First Rate of BUILDINGS.

Thefe are of the fifth rate, and may be built oi any dimenlions whatever. Sixth Kate of BUILDINGS. Every dwelling-houfe, ware-hou'e, ftable, and other building (except not being dwelling-houfes, as are defcribed to be of tb.e firlf rate) wfiich is at the diildnce or 5 feet from any public road, ftreer, cr caufeway, and is detached from any oiher building, net in the (iuiie j;ofleffion, at leaft 30 feet, or connected with any other huildirg cnly by a fence or fence- wall. Thele may be built of any dimtnficns, and with any materials ■.vhatever. Seventh [ 3^«> 1 Seventh Rate of BUILDINGS. EvcRV crane -houfe, or any wharf or qtiay, every fhamble, wind-mill or w?ter-mill ; every building fituated without the cities of London and Wedmlnfter, and t!ie liberties theieof, ufed for workshops or Hryng pi .ces for tanners, kllmangcrs, glue-mnkers, fize-makcrs, calHco prin- ters, whitflers, whitinsj makers, curriers, lea her-dreffers, buckra n- ftiftcners, oil-clcth p.nnters, wool ft i piers, throwfters, parchme it-ii»ikcrs and paper- makers, lo long and at ki h times, as t"- ey arc ufed far fo;ne or one of thofe purp fes, and no lonij;er, fh.iil be deetn-d to be of the feventh rate, and may be built of any dimenfions, and with any ma.cnals what'-ver ; but they are not to be covered with pitch or tar, or any other inflammable material, nor ever to be converted to any other ule tiian as abi vementiontd. N. B The aft makes an exccptioi to the m^-terials of crane-houfes, and expre-sly fays. That the wiiole, or any iduitio. thereto, (hall be built of llone, brick, (lite, tile, oak, elm, ftetl, iron oi brTs. It may be neceiraiy hereto obferve. That the aft pr> vides againft any doubts which may arife cuncernmg offices th.t belong to any building of the firft, fecond, thi'd, or fourth rate, and therefore fays, ' hat every fuch office, if detached from the buildinj^ to which it belongs, and con- nefted therewith only by a fence or fence wall, or covered palTige open on one or both fides, fhall be deemed to be of the rate fuch building would be of, as if the lame was not any ways connefted or belonged to any fuch building. What particularly concerns the Bricklayer in this Act. There are only the firft, fecond, third, and fourth rates of Building, vshofe thicknefs of external and party-walls are defcribed in the aft. The aft direfts. That every mafter-workman, or owner, (hall give 24 hours notice to the lurveyor, in whofe diftrift any building, from the firft to the feventh rate, is to be altered or erefted. As buildings in general are oftener began by the bricklayer than by the carpenter, it naturally fol o.vs, that it will be the bricklayer's bulinefs 10 oive luch notice, except where a foundation is to be piled or planked; and then it becomes the bufinefs of the carpenter. External Walls. The Aft of 14 George III. calls every front, fide, or end wall, &c. (not being a paity-Wrtll; an external wall. The ( 3^1 ) The footings to the walls are to be with eq-ial projeilion on each fide,. but where any adj iin'ng building will not admit of luch p''oj dli jn to be made on the fide next adj wning to fuch bu Ming, the ad: allow i. to be d ^ne as near as the cale will admit, and this to each of the four rates. The timbeis in each rate may be Tuppo^ed as g'rders, beams, or trim- minti joilb, &c. which might be illulTirated with an engraving, to fhew tiieir be::ring on the wall, which in all cafes, and in ail the a!)ove four rates, may be as much as the nature of the wall will admit, pro- vided there is left 4 inches between the ends of fuch timber and the ex- ternal furface of the wall. The joiiits of th:- brck-work might alfo be fhewn, and might anfwer to the exprels number of bricks of which fuch wall is to be compofed. It miy now be nectflary here to lay lomething further, relative to ex- ternal wa Is. External Walls, and other external inclofures to the firft, fe- cond, third, fourth, and alfo the fiHh rate of building, when built hereafter, mult be of brick, flone, artificial flone, lead, copper, tin. Hate tile, or iron; or of brick, done, and fuch artificial ftone, lean, copper tin, (late, tiie and iron together, except the planking, piling, &c for the foundation, which may be of wood of any fort. If any part to an external will of the firft and fecond rate, is buik whol'y of lloue, it is not to be lels in thicknefs than as follows. Firll rate, 14 inches below the ground floor i 9 mches above the ground floor. Second rate, 9 inches above the ground floor. Where a receis is meant to be made in any external wall, it muft be arched over, and in fuch mmnT, as that the arch, and ths back of fuch recefs (hall refpeftively be of the thicknefs of one brick in length j it is therefore plain, that where a wall is not more than one brick thick, it cannot have any recefs. No external wall to the firft, fecond, third, and fourth rate, is ever to becoiiie a party-wall, unlefs the fame fliall be of the height and thicknefs above the footing, as is required for each party-wall to its ref- pedive rate. Of Part y-w alls. Buildings of the firfl, fecond, third, and fourth rate, which are not dcfigneil by the owner thereof to have feparate and diftind fide walls, on fuch parts as may be contiguous to ether buildings, mud have party-walis; and they are to be placed half and half, on the ground of each owner, or of each building refpedively, and may be built thereon, L 1 1 1 without ( 3'2 ) without any notice being given to the owner of the other part, that !<; to fay, the firfl: builder has a right fo to do, where he is building againft vacant ground. F;irty-vvall?, chimnies, and chimney- fhafts hereafter to be built, muft be of good found bricks, or ftone, or.of found bricks and llonc toge- ther, and muft be coped with flone, tile or brick. Party- wallf, or additions thereto, muft be carried up iS inches a- bove the roof, meafuring at right angles with tlie back of the rafter, and 12 inches above the gutter of the higheft building, which gab'es agiinftit; but where the height of a party- wall fo carried up, exceeds the height of the blocking courfe,. or parapet, it may be made lefs than one foot nbcve the gutter, for the diftance of 2 feet 6 inches from the front of the blocking -courfe, or parapet. Where dormers or other eredtions are fixed in any flat or roof, within 4 feet of any party-wall, fuch party-wall is to be carried up againft fuch dormer, and muft extend' at leaft 2 feet wider, and to the full height of every fuch dormer or erection. No recefs is to be hereafter madein any party-v/all of thefirft, fecond, third and fourth rate, except for chimney -flues, girders, £ic. and for the ends oPwalls or'piers, fo as to reduce fuch wall in any part of it, to a lefs thicknefs than is required by the ad, for the higheft rate of build- ing to which fuch wall belong?. No opening is to be hereafter made in any party-wall, except for communication"from' One ftack of ware-houfes to' another, and from one ftable building to another, all which communications muft have wrought iron doors; and the pannels thereof are nOt to be lefs than one quarter of an inch thick, and to be fixed in ftone door -cafes and fills. But there may be openings f'or pafflVges or \Vays on the ground, for foot paftengers, cattle or carriag-^s, aind muft be arched over throughout with brick or ftone, or brick and ftdiie together, of the thicknels of a brick and haif at the leaft, to- the-fir.ft and fecon^ rate, and one brick, to the third and fourth rate. And if theie is anycellar or vacuity under fuch paflage, it is to be arched over throughout in the fame manner as the pafla^c over it. No party wall or party-arLh, or Ihaft of any chimney, new or old, muft be cut into, other than for the purpofes as follow. If the fronts of buildings are in a line with each 'other, a break may be c t, b. th in the fore and back front of fjch building, (as may be al- ready erected), for the purpole of inferting the end of fuch other exctrnal wall which is to adjoin thereto; which break muft not be more than 9 inches dtcp, from the outward faces cf fuch external walls, and not to be cut beyond the centre ot the purty-wall tneicto belonging rtp.d further, lor the u e of inlcrtii.g br^fl'ummerb and ftory ports, that are to be fixed on the ground floor, cithtr in the front or back wall, which ( 3^3 ) which recefs miy be cut from the foundation, of fuch new wall, to the top of fuch brelfummer 14 inches deep from the outward face of fuch wall, and 4 inches wide in the cellar Ilory, and 2 inches wide on the ground fliory. And further, for the purpofe of tailin.;-in ftone fteps, or ftone land- ipgs, or lor bearers to v\ood flairs, or for laying-in ftone corbels for the fupport of chitijney jauoib?, girders, beams, purloins, binding or trim- ming joifts, or other principal timbers. Perpendicular recefles may alio be cut in any party-wall whofe thick- nefs is not lefs than 13 inches, for .the purpofe of inferring walls, and piers therein, but they muft not be made wider than 1^ inches, ormjre than 4 inches deep, and no fuch recefs is to be nearer than lo feet to any other recefs. All fuch cuttings and recefles muft be immediately made good, and eflldtually pinned up, with bri.k, ftone, flate, tile, (hell, or iron, bed- ded in mortar. No party-wall to be cut for any of the above purpofef, if t':e fame will injure, dilplace, or endanger, the timbers, chimnies, flues or inter- nal finilhings ot the adjo.ning buildings The aft alio allows the footing to be cut off on the fide of any party- wall, where an independent lide-vvailis intended to be built againll fucli party wall. When any buildings I'the inns of court excepted) that are ereded over gatewa-^s, or public palTages, or have diffennt rooms and floors, the pro- perty of difl'erent owners, come to be rebuilt, they mull h ive a party- wall, with a party- arch or arches, of the thickne.'s of a brick and half at the leafl, to the fiift and feconJ rate, and of one brick to the third and fourth-rate, between building and buiding, or between the different rooms and floors that are the property ot different ovvn( rs. All mns of court are excepted from the regulation as above, and are onlv neceffit.. ted to have party wa'Is, where any room or chamber com- municates to each feoarate, and difrinft ftair-cafe, and which are aifo fubjedl to ti.e fame regulations as re'pecl other party-walls. it a bui'dingof a lower rate, is lituated adjoining to a building of a higher-rate, and any addition is intended to be made thereto, the party- wall mul be built in luch mamer, as is req^ui'-ed for the rate ot fuch higher rate of building lo adjo^nmg. When any party-wall is raifcJ, it is to be made the fame thicknefs, as the wa.l is of, in the itory ntxt below the root ot the highell outlding adjoining, but it mull not be railed at all, unlefs it can be done with fatety to luch wall, and the building adjoining thereto. Every dwtUing-houie to be built which contains four flories in height fiom the tounddtion, exclulive of rooms in the roof, mull have its party- M m m m wall r 3H 1 • wall built according to the third rate, althoigh fuch dwelling-houfe may be of the fourth rate. And every dwelling houfe to be built in future which exceeds four ftorics in height, from the foundatio.i, excluive of the roorriN in the roof, mufthave its party- wall built according to the firft: rate, although fuch houfe may not be of the firft rate. C H I M N I E s, &c. No Chimney is to be ereded on timber, except on the piling, plank- ing, &c. of the foundations of the building. Chimnies may be built back to bdck, in party-walls j but in that cafe they muft not be lefs in thicknefs irom the centre of fuch party-wall than as follows. Firft rate, or adjoining thereto, mull: be one brick thick in the cellar floryj and half a brick in all the upper ftories. Second, third and fourth rate, or adjoining thereto, muft be three- fourths of a brick thick in the cellar ftory ; and half a brick in all the upper ftories. Such chimnies in party-walls as do not ftand back to back may be built in any of the four rates as iollows : From the external face of tht party-wall to the inward face of the back of the Chihiney in the cellar ftory, one brick and an half thick, and in the upper ftories, one brick thick, from the hearth to 12 inches above the mantle. Thole backs of chimnies which are not in party- wails, to the firft rate, muft not be lefs than a brick and half thick in tlie ctllar ftory, and one brick thick in every other ftory, and to be from the hearth, to 12 inches above the mantle. If fuch chiinney is built againft any other wall, the back may be half a brick thinner than that which is above defcribed. Thole bncks of chimnies which are not in party-walls of the fecond, third and fourth rate, muft be in every ftory one brick thick, at leaft, from the hearth, to. 12 inches above the mantle. Thefe backs may be alio half a brick thinner, if fuch chimney is built againft aAy other wall. All breafts of chimnies, whether they are in party-walls or not, are not to be lefs than one brick thick in the cellar ftory, and half a brick thick in every other ftory. All withs between flues muft not be lefs than half a b. ick thick. Flues may be built oppolite to each other in party- walls, but they muft not approach to the centre of inch wall nearer than 2 inches. All chimney breafts, next the rooms, and chimney backs alfc, and all fluts aie to be rendered or pargeited.

The bafement or ruitic ifory, is divided into a number of rooms for the principal fervants j the kitchen ana other convtniencies ihould be detached from the manfion, that it may not be incommoded by iieain or heat : the coach houfe and ilablfS fl:iould be a building anfwerable on the other fide of the manfioa ; which, by the help of a colonade, will form a communicaticn, and have an agreeable effedt. A EXPLA- [ 2 ] Explanation of Plate IV. Plate IV. is an elevation of the Corinthian order. The Corin- thian, being a very rich order, never fhevvs its elegance fo perfedtly, as when placed in a fingle feriss on the principal ftory. It fliould confitt only of three ftories, a bafement floor, a magnificent principal floor, and an attic; the louder floor, by being funk a little, makes a pedeftal agreeable to the order, which fliould be always one-fifth of the height of the whole order. Though we rtcommend a ruftic face in the bafe- ment flory, yet the delicacy of the order, that is to be raifed upon it, fhould always be confidered, and that it ought net to be too rude and harlh. 1 he builder tliould run a courfe of ilone, about one foot three inches high, on the level of the ground, which fornis a plinth, on which the ruftic is to be raifed; which, continuing in a ftraic line, forms a fub- plinth to the pedeftal on which the columns are to be railed. The fafcia which terminates this ilory fhould he equal in bread h to the cap of the pedeftal. On this fhould be raifed a pedef- tal of the Ionic order to the bottom of the windows, on which the decorations of the window fhould be placed. Thefe decorations are fo various, that the archited: will generally make ufeof hi^ own judg- ment in the choice of the;ii ; but he fhould be particularly attentive never to ule columns or other decorations of a luperior order, as that would be exceedingly abfurd ; for a more enriched order would give an ill contraft to the other columns, which are the principal objedl, and where the greateft decoration is required. For example, if, in this elevation, we fhould decorate i ur win'ows with the Compufite order, the eye would naturally be ofFinded, that thoie in the principal fabric hid not as much decoration as the others. We thereiore re- commend the Ionic order, as a proper decoration for the windows on thofe occafions. Kawng explained the decorations of the vv'indows on the principal floor, it is nectflary to obferve, that a flat w.ill wholly unornamented, cairicd up tu ihe height of the columns, wiil have a dead afpedl ; to prevent which, the windows ot the attic and ftring (or falcia) are properly introduced ; and as the entablature raifed up- on the columns is carried aK ng the n. ked wa.l, this gives an unifor- mity, very happily, to the face of the whole building. As every part fliould be made to correfpond with the whole, in fuch an elegant ftrufture as we are liere otfc.ibing, it fliould not be entirely plain, therefore a baluftrade with t; cir proper pedcflals, crowned with vafes, &c. will be judicioufly added. I 3 ] > 9m>rt P LA T E V. Is defigned for. a door for a room of Hate. We have endeavoured to fliew how elegant a door is to be conftrudled upon this order, with the ftri-dtefl adherence to the eftablifhed rules of Palladioj and having that before you as a ilandard, you will find no difficulty to vary it iti many refpetis. By fluting the columns, it gives an opportunity of in- troducing a capital, compofed of a lighter nature, the architrave round the door being funk, and the door pannel raifed ; and, by adding the architrave into the freeze, vye have a large fcope to introduce luch orna- ments, as will, with propriety, add much to its dignity ; and by hav- ing the pediment open, we may, without deviating from the order, in- troduce a fhield with proper fupporters, which will give it an air of grace and beauty. P LA T E VL Ts a plan and elevation for a farm-houfe, intended to be built for a farmer of eminence in the county of Middlefex ; the front extends fe- venty-eight feet, and is meant to afcend with three fteps, with a portico over them, which will add fomc little degree of elegance to the building*. '"'■■ 'The plan islaid out in the following manner. APafFageorHall B B Parlours C Dining Room D Kitchen IG Clofet E Dairy FBrew-houfc H Lobby I Wafli-houfe K Pantry L Great-Stairs M Stair-cafe for Servants N Paflage The Barns, Cow-houfes, Cart-houfcs, Stables, Pig-fties, Hen-houfes, and other buildings, made ufe of in the farming bufmefs, form two wings at the back ot the houfe; and, as they have a communication from a road by the fide of the houfe, it will fiand detached ; and by having a grafs plat, and fmall gravel walk up to the front, it will make it have an agreeable appearance. PLATE VII. Is a Dcfign for a Chimney-Piece. We are in nothing left fo much to the didates of fancy, in the whole fcience of Architedure, as in the conftrudtion of Chimney- pieces; and it is deemed an article of fuch efiTential importance, that no room, whether plain or elegant, can, with any degree of proprie- ty, be finiflied without it. We have here given two different defigns, both of which are fufceptible of all the grace of ornament ; and in thefe two figures we have fketched various kinds, which are proper to cither : wc have decorated the one with columns, and the other with B i^n r 4 ] an open pilartcr, which render them defigns of various fpecies, adapted to different prices, and alfo to the elegance or plainnefs of different aparrments ; and as the openings of chimnies are fo very various, we would advife the following particulars, viz. to have a chimney which is four feet high, to be kept as nearly fquare as poffible; but, if there is any difference, to be wider, and lo on, in proportion, down to about three feet four inches high. Columns have the befl effe• ; the fommering of each courfe will appear clear, by in- fpedting the dotted lines. [ ^7 ] PLATE XXIX.

The fedion is taken through the wards, nurfes room, circular piazza, and area : the dotted line Z in the plan lliews its courfe. In the bafement ftory we fee the vaults under the ftreet for coals ; the areas, and ftairs down to them; the houfe-keeper's room, cook's-room, (being under the center of the wards) rooms under the nurfes rooms : circular paflage (under piazza) which receives light from grates in the footing of the piazza : large vaults for ftores, &c.

A Half of the plan D D Tombs B B Steps alcending up to the Bone- E Entrance into the Bone-houfe houfe F Jnfide of ditto C C Footing round ditto G G Buttments The ftudent is to obferve, that as all churches lliould he built in the Gothic tafle, as being more fuitable to fuch ftruftures than the Grecian tafle, fo likewife every part appertaining to it muft be in the fame ftyle, (as this defign for a bone-houfe, and various other defigns introduced in thecourfe of this work for religious purpofes.) For true it is, nothing can be more abfurd than mixing one tafte with the other, as is too commonly the cafe, for inftance, tiie towers of Weflminfter Abbey, what a medley of Grecian and Gothic architefture is there ! The choir of the fame place is decorated w'x^z fcreen of Grecian co- lumns, &c. to the altar, while every other objetfl round is Gothic ! Guildhall is another proof of this unaccountable fancy — all the upper part of the building has been repaired in the Roman ftyle, doubtlefs with the intent of fhewing how far inferior the Gothic part below is to its vain and towering beauties above — the choir to Canterbury cathe- dral is Grecian, and numberlefs other places in England can produce inftances as i-idiculous as thefe. I think no true confiderate admirer of Grecian architecfture can with confidence maintain that fuch medley 'work fhews real tafte, it can only fhew a love of novelty, which will always refle(5ta difgrace on the intru- der of Grecian architedure on Gothic remains. If any of thefe venerable piles need repair, or any alterations, let it be defigned in the exaft manner of the original work, and feek not, by introducing fome new whim or fancy, to caft a mark of /corn on what in- deed fliould be our pride to imitate and preferve in its original purity and grandeur. Some architecfts of late years have invented an extraordinary tafle for Gothic buildings, as the feats of juflice in Wefiminfter-hall — the arches that compofe the fame are purely tfiodern, and I may fay, with the reft: of the ornaments, need no other convidion of their deformity and extrava- gance than to be compared with the old Gothic — thus is one of the nobleft rooms in the world rendered odious, when before it was fo truly beautiful and magnificent. I muft confefs myfelf a zealous admirer of Gothic architedure — af- firming with confidence, nothing can be more in charadler, and better a- dapted to a place of worfhip, than that awful ftyle of building, and that Grecian and Roman architefture ftiould be confined to manfions and other ftruiftures of eafe and pleafure.
