PEEING the Buflnefs of Dialling , if Mecha- ^ nically conjidered, is ofitfelf a Thing fo natural and eafy, one would wonder , after fo much learned Bujlle as the Mathematicians have made about it, that they floould have more perplexed and obfcured than promoted the Knowledge of that ufeful and en- tertaining Art amongst the Generality of Mankind. The different Ways, in which theje Gentlemen, have hitherto choje the World fhould fee that ufeful Subject handled, would certainly have been right and proper , and liable to no Exception, if all Men were Mathematicians : But how few are fuch f And therefore their having treated of Dialling in a Geometrical, Inffrumental or Arithmetical Me- thod, I am Jure cannot pojjibly be of any Ufe or Sig- nification to fuch as know nothing at all of thofe Sci- ences, or the Dodtrine of the Sphere. Certainly, there are two very different Ends of writing Books, which treat of any Art or Science the one is to advance the Art or Science itfelf, and the other to inffrudl Learners. Now, with refpedt to the Former, the Extent and Capacioufheis of the Subject is chiefly to be re- garded', and nothing is to be omitted which pro- perly falls within the Compafs of the Art or Sci- ence treated of-, but wit h ^rejpedt to the latter, the Capacities of the Learners are principally to be con- jidered, and Notice is to be taken, not of whatever may be known or done by the Art or Science treated A z of iv PR E FACE. of, but only of what is moll ufeful, and withal nioft eafy to be known. The mod proper and rational Method, therefore, to make any one Majler of any Art or Science, is to intr oduce it to him after the moft plain, familiar and natural Method, and to teach him at fir ft only fo much of the Art as is really ufeful in common, JL>i lo., and withal mojl eajy to be underjlood ; and when he has gone through, and is become Mafter of what is mojl ufeful and eaiy, he will be enabled with more Eaje to conquer the more difficult Parts oj. it, and to purfue the Study of it after a more lea ned Maimer, if his own Inclinations qr Pro- feffi on Jhall incline him fo to do. Upon, thefe Corfi derations, and with this View it ( was that I drew up this Treat if e of Meehan ick Dialling, becauj'e of all thofe who have hitherto treated upon this Subject in the Englifh Tongue for the Inftrudtion of Learners, not one of them jeems to me to have thoroughly confidered what I have now premijed. By the Method I have obferved in this Treatlfe , the Length and Drynefs oj" the Study of Dialling (which has dijeouraged many ) is quite removed ; and it is mow rendered not only very ufeful, but perfectly eafy and entertaining : And I think with- out Vanity I may venture to affirm, - that by the Help of this Book only, the Learner may obtain a competent Knowledge in Dialling, in much lefs Time, and with much lefs Trouble, than he can by the Ajfifiance of any other, or indeed ail the TreatiJ'es which have yet appeared in Englifh upon this Subject : where he will either find the eafy and ufeful, and the difficult and ufelefs Elements of this Art propiifcupufly w/injudicioufly exhibited PREFACE. v and taught together or elfe the SubjeCi treated of after fuch a Manner as can never he comprehended by any one that does not underfland fome of the abftrufeft Branches of the Mathematics/* But It is high Time that I floould now proceed to give the Reader the Particulars of what he may expert to meet with in the following Treatife. In the firft Place, he is made Majler of thofe few Geometrical Problems, which may be of Se r- vice to him in Mechanick Dialling. Secondly, I have taught him not only the Ufe ... of the Quadrant and Trigon, but alfo how to make thofe univerfal Injlruments , which for their Sim-; plicity, and the great Ufe they are of in Dialling are never enough to be valued. 1 have likewife. taught him not only the Ufe of but alfo how to make Dialling Scales, and this is not to be met with in any other Treatife extant upon this, Subject. Thirdly, I have given him fuch plain and ample Directions, that it will, be impojfble for him to tnifcarry in making of a Dial for any Place in. the World, whether the Dial be Equinoctial, Hori- zontal, EreCt, Declining, Reclining or Inclining. Fourthly, to thefe I have added plain and eafy Directions for making of RefleCtive, Refractive and Globe Dials. I have likewife taught the Reader how. to make a Crofs Dial, and in this, on account of its Novelty, I have been very full and particular , not only m fhewing him after what Manner it mujl be made, but in having the feveral neceffary Views or Po- ftions of it engraved on Copper. I was tempted 1 to be thus particular, by reafon I never yet fa%d- * Scubas Geome.t 17, Aftronqjny, fcfr* a 3 Vi P R E F A C E. or heard that there was any other Dial of that Sort m England, befides that which I have menti- oned m this Treatife. And I have alfo in this new Edition given a Copper- plate of, as well as Direc- tions for making the new invented Star-Dial. Filthly, I have furnifhed the Pleader with the following very ufefui and accurate Tables, all adapted to the new Stile. 1. A Table of the Sun’s Declination, exabily cal- culated for the Tear 1764, and which (for the Ufe of Dialling) will ferve for this Age without any fenfible Error. 2. An exact Table of the Equation of Tim tfor the Regulating c/’ Clocks and Watches by a Sun Dial. 3. A Table for the converting of Flours and Minutes of Time into Degrees and Minutes of the Equinoctial, and e contra. 4. A Table for drawing the Hour Lines upon all Horizontal, &c. Dials, from the Equinoctial to the Poles, 5. A Table of the Three Requifites in Dialling , foewing the Subtile’s Diffcance from the 1 2 a-clock Hour Line; the Stile’s Height; and the Inclination of Meridians anfwering to the feveral Degrees of the Declination of your Plane. 6. A Table foewing the Sun’s Altitude for every Flour and Quarter of the Day, at his Entrance into the 12 Signs of the Zodiack. Sixthly, I have given a plain and familiar De- fcription of the Sphere, for the Sake of fuch as are inclined to have a true Notion ofjuch Circles in the Heavens, as are frequently mentioned in this and other Books of Dialling. Seventhly, In Chap. XXIII. is a Collebhon of Mottos PREFACE. vii Mottos for Dials in Latin and Englifh, fuitable to almofi all Places where Dials may be fixed. Eighthly, That nothing may be wanting to ren- der this Work compleat , I have added a new and corredt Alphabetical Table of the mofi eminent Ci- ties, Towns, &c. in the whole Worlds J, hewing at each Place the Elevation of the Pole and Difference of their Meridian from London, and this Table may be depended upon to be the belt that is extant, be- caufe I have fpared neither Time nor Pains to cor - reSl as many as I could from celeftial Obfervations. Ninthly, In Chap. XXVI. 1 have been very full and particidar concerning the Manner of making and painting of Dili Planes, and alfo concerning the preparing the different Colours and Oils proper for that Purpofe and in this 1 hope to merit the Ap- ' probation of thofe who live in the Country , and cannot upon all Occafions have the Affiance of a profefied Painter. And I have alfo added Chap. XXVII. concern - ing Painting Houfes,&c. being thoroughly convinced that all thofe Country Gentlemen, and others, who are inclined to be good Huibands, will think it very well worth their Perufal. Laftly, Though it may appear a little foreign to my prefent Purpofe , yet for the Entertainment of the curious , I have fhewn (in Chap. XXV.) how naturally the two Hands of a Watch or Clock reprefent /^Motions of the Sun dWMoon. And now wfhing my Reader as much Benefit from the Perufal of this Treat if e , as I have had Pleafure in compofing of it y I remain his faithful friend whilfi CHARLES LEADBETTBR. Viii CONTENTS.

IALLING originally is a mathematical Science, attained by the philofophical Contem- plation of the Motion of the Sun, the Motion of. the Shadow , the Confutation of the Sphere , the Situa- tion of Planes, and the Confi deration of Lines. Explanation. The Motion of the Sun is re- gular, it moving equal Space in equal Time-, but the Motion of the Shadow irregular in all Parts of the Earth, unlefs under the two Poles, and that more or left, according to the Conftitution of the Sphere,, and Situation of the Plane: And therefore Scientific Dial ills, by the geometric Confideration of Lines, have found out Rules to mark out the irregular Motion of the Shadow in all Latitudes, and on all Planes, to comply with the regular Motion of the Sun . But though we may juft ly account Dialling ori- ginally a Science, yet fuch hath been the Generality of many of its ft udious Contemplators, that th ey have communicated their acquired Rules, whereby it is nowbecome, tomanyofthe Ingenious, nomoredif- ficult than an Art, and, by many late Authors, fo intituled ; nay more, by Means of this fmail Traa- tife, it will fcarce be accounted more than a manual Operation-, for though the Authors I have met with feem to prefuppofe their Reader to underftand Geo- metry, and the projecting of the Sphere already, or elfe endeavour in their Works to make him under- ftand them, as if they were abfolute necelTary to B be 2 Mechanick Dialling.

Thus they not only difcourage young Be- ginners, but alfo difappoint many Getlemen and others, that would willingly either make them themfelves, or fet their Workmen about them, if they knew how to make them. The following Pages I have therefore compofed, for the Help of thofe who underhand neither the ProjeSlion of the Sphere, or geometrical Operations. P R O B. I. To divide a right Line given [as A B) into two equal Parts.

D C on the other Side ; where thefe two Arches crofs each other, lay a Ruler, and draw the right Line D C, and it will divide the ; A- XT> m.X Cl...-- -B X C right Line given in E, the Middle thereof. Or the fame given right Line may be divided into two equal Parts , by fetting oneFoot of theCompaffes on the End of the Line at A, and there defcribe the dot- ted Circle, and then, with the fame Extent of the Compaffes, draw the other dotted Circle at Bj lafl- ly, draw the right Line F G, and it will divide the given right Line AB in E, as before.

Of Dialling in General, jP\ X A L LI N G is a very curious and ufeful Art, and teacheth us how to draw Hour-Lines up- on all Sorts of Surfaces or Planes, for any Place in the World, and thereby to know the apparent Hour of the Day, by the Shadow of a Stile* fixed on the Plane parellel to the Earth's Axis, which Stile can have no more than three Pofitions, viz. Per- pendicular, Oblique, or Parellel, which fhall be ihewn in their proper Places. -I" A Dial-Plane is that Flat on which a Dial is intended to be proje&ed. The Dial-Planes, on which Hour -Lines are drawn, are thefe following : * The Stile in Dialling iignifies the Pin or Cock of a Dial, the Shadow of which points out the Hour. f The whole Buiinefs of Dialling may be reduced to three general Heads; the firjl cenfifts in finding the Place of the Subfile, or where the Stile is to be placed; the fecond in drawing the Hour-Lines', and the third , and laft, if the Dial-Plane be moveable , in duly placing and fixing the fame, after the Dial is drawn thereon; or elfe, if the Plane, whereon the Dial is to be drawn, be unmoveable 9 and already fixed, in finding the Pofition or Situation of the faid Plane, viz • whe- ther it be a dir? ft or declining Plane, and if the latter, how far it declines .

Chap. III. Take a flat Plate of Brafs, about a Foot fquare ; or if you cannot eafily procure Brafs, get a Piece of good dried Oak, well planed on both Sides. For the Hour Lines. Draw with your Compares three -f* concentric Circles thereon, to contain the Figures, which di- vide into 24 equal Parts ; then lay a Ruler to the Center, and draw Lines to thofe equal Divijions in the Circle , and they fhall be the true Hour Lines fought. For the Stile. Eredt in the Center of the Plate a Pin or Wire perpendicular to the Plane, as A B, and that lhall be the Stile truly fitted to the Dial. You mull obferve, that 15 Deg. || in the Equi- noctial is one Hour in Time , as you may fee more at large by Table III. and therefore, if you take 15 Deg. from your Line of Chords , and fet it off from the 12 a-Clock Line each Way , that will give you the Hours of 1 1 and 1, and 30 Deg. will give you the Hours of 10 and 2, &c. and thus the whole equinodiial Circle will be divided into 24 equal Parts or Hours , as above. But becaufe this Dial, when thus drawn on one Surface or Side of the Plane, will ferve only for one Half of the Year, viz. while the Sun is on one Side of the TLquinodlial, to wit, from the 22d of March to the 2 ill of September ; and therefore to make it f See Problem VI.

Of the Equinoctial Dial. ferve for the whole Tear , it mult be doubly drawn, 4 . e. on the lower , as well as on the upper Side or Surface of the Plane, and then the Wire, which ferves for the Stile , mu ft go through the Center , and mult extend itfelf 6 or 8 Inches more or lefs beyond the Surface of the Plane, and ltand at right Angles therewith ; and then that Dial is fnijhed. How naturally the Hour Lines of all Dials are drawn from the Equinoctial Dial is fhewn in Chapter XXI. To Jet this Dial truly. You mult raife the Wire, which represents the Stile, to the Latitude of your Place, by applying that Edge of your Quadrant, in which the Sights are fixed, to the Stile, and when the Thread cuts the Limb in the Degrees of the Latitude of your Place , then doth the Stile point to the Poles of the World, and the Dial itfelf lieth parallel to the EquinoSiial Circle in the Heavens. But lfill here wants a true 12 a-clock Hour Line , which muft be found as I lhall lhew in the next Chapter, and then placing the Dial, fo that at 1 2 a-clock the Shadow of the Stile may fall in the 12 a-clock Hour Line, that you find by tire Directions fol- lowing : and thus will your Dial be truly pl.ced, which you may fallen by fixing two Pieces of Iron at each End of your 12 a-clock Hour Line upon your Dial Poft, and in thofe put the Stile of the Dial to the Height , which was found before by the Help of your Quadrant. c it A P. c iS Of the Horizontal Dial.

It matters not what Form the Plane, on which you would draw an Horizontal Dial, is, whither it be round, fquare , or triangular, but they are gene- rally drawn round, as on Plate 3.

The Dial being thus finilhed, the next Thing is to fet it truly, tor if it be ever fo truly made, and not well fet, it will go wrong: therefore you muft firft fee that your Poll, on which the Dial is to Hand, be truly level every Way, which you may try by your Quadrant, on which draw a Circle as large as the Top of the Poll will bear; in the Center there- of place a Pin exacily upright ; in the Forenoon, when the Sun (hineth, let the End of the Shadow of the Pin touch the Circle, where make a Mark ; let Things Hand thus till Afternoon the fame Day, and then obferve where the Top of the Shadow of the Pin toucheth the fame Circle; there again make a fecond Mark ; then divide the Diftance of thefe C 2 two 20 Of the eredl direEt South Dial.

Note, Inttead of the Quadrant GE, you may draw a Semicircle on the Center H, and divide it into 12 equal Parts, and fo Lines drawn from the Center at H will give the Points in the Line DEF, as before. Or, if you apply the Center of the Equi- noElial Dial to the Center at H, the Hour Lines on the EquinoSlial Dial will cut the Line DEF in the Points where the Hour Lines on the Horizontal Dial mull pal's.

For Inflance , January 14 at Noon, I fee the Clock is 9 Min. 44 Seconds too fafl for the Sun , &c. therefore the Clock Ihould be ietpMin. 44Seconds fafler than a Sun Dial.

HpHIS is a Table of Meridional Angles ; the frfi Column is the Latitude , which ferves for an Ho- rizontal Dial , and the lajl Column is the Comple- ment of the Latitude, and is for making FrellDireSl South or North Dials, and are thus to be ufed: lO* Suppofe in the Latitude of 53 Deg . I would make ^Horizontal , and alfo an Eredl Diredl South Dial. Firft, For the Horizontal Dial. See Plate 3. Fig. 2. < Now (altho’ this be projedted for a higher Lati- tude, yet it may ferve our Turn here well enough to fhew how to ufe the Table:) I look into theT able, and find againft 53 Deg. and under 1 1 and 1 a-clock 12 Deg. 5 Min. Take this 1 2 Deg. 5 Min. in your Compafles (from the Line of Chords, that you draw the Quadrant AB by) and fet one foot in the Me= ridian CA, and turning the other each Way, it ihall give the Points where the Hour Lines of 1 and 1 1 mull pafs; under 10 and 2, and againft th zfame Latitude 53, I find 24 Dag. 43 Min. which take from the Line oj Chords, and ftt each iFay from the Meridian C hap. XIX. The Explanation and Ufe, &c. 8 1 Meridian as before, and it gives the io and 2 a- clock Hour Lines. For the Hours 9 and 3 you muft take 38 Deg. 37 Min. for 8 and 4 a-clock, you muft fet 54 Deg. 12 Min. and for 5 and 7 fet 71 Deg. 28 Min. the Chord of 90 gives the 6 a-clock Hour Line, and fo by drawing Hour Lines from the Center thro' thefe Points, thus fet off in the Arch A B, are the true Hour Lines required. Secondly, For the Eredi Diredl South Dial. See Plate 4. Fig. 2. Suppofe l would make an Eredi Diredl South Dial for the Latitude of 53 Deg. the Work in this is the very fame as I have (hewn in the Horizontal Dial ; only here you muft feek your Latitude in the lajl Column on the right Hand, or its Complement on the left Band-, and againft either, for 1 1 and 1 a-clock, 9 Deg. 10 Min. for 10 and 2, 19 Deg. 9 Min. are to be fet off from the Meridian by your Line of Chords ■, for 9 and 3 a-clock are 31 Deg. 2 Min. for 8 and 4 a-clock are 46 Deg. 1 2 Min. for 7 and 5 a-clock are 66 Deg. 10 Min. and for 6 a-clock are 90, and thus for any Latitude of even Degrees, an Horizontal and South Diredl Dial may be expe- ditioufly made by help of this Table and your Line ■ of Chords. What has been faid of the South Eredt Dial is alfo applicable to the North , and therefore needs no Example. G TABLE TABLE V.

And by this means you may make the like Table for your own or any other Latitude. * For further Satisfaction herein you may fee my Syfiem of A fire no my, You L Page in. CHAP. Chap. XX.

P age 56,1 have fhewn how to ufe theLine of Chords, in meafuring of any right lined Angles. The Lines of Flours Latitudes are general for pricking down all Dials with Centers , as the Horizontal, South Diredl, &c. as for Example. Let it be required to draw a Dial upon an Horizon - taiPlane for th z Latitude of London 5 1 Deg. 3 2 Min . See Plate 1 1. Fig. 1. For the Hour Lines and Stile’s height. Draw CD for the Meridian or Hour Line of 1 2, and crofs it at right Angles in C, with AB ; then from the Scale of Latitudes , fet off CA and CB each equal to 5 1 Deg. 32 Min. forth e Stile's height. Then take the whole Scale ofSix Hours in your Compares, and fet it from A to D; draw AD and BD : Divide the Lines AD and BD as the Scale of fx Hours is divided, and thro ’ thofe Divifons draw Lines to the Center C, which fhall be the true Hour Lines fought, to which put their proper Figures as you fee done in the Dial. This is a very ready and eafy way to deferibe the Flour Lines on any Plane. For 90 Of the Ufe of the Scales in Plate II. Ch.XX. For the Stile. Take CA in your Compares, and fet from D to E,draw CE for the Stile, which mud; Hand perpen- dicular upon the Line CD, and fo is your Dial com- pleatly finiftied. Ever remember to make an Allowance for the Fhicknefs of the Stile in all Dials, as I have cautioned you before. An Example. Of a North and South Eredt Diredt Dial for Pen- zance inCornwall,who{eLatitudeis $ o Deg. 8 Min. N . See Plate 1 1. Fig. 2. This Dial is made the very fame Way as I have juft now ihewn in the Horizontal Dial, only inftead of taking the .Latitude from the Scale of Latitudes, you muft here in this Dial take the Complement of the Latitude of the Place, viz, 39 Deg. 52 Min. and fet it from C to A, and B, which is alfo the Stile’s height. For the Hour Lines of the South and North Dials. Take the Scale of ' fix Hours, and fet from A to D, draw AD and B D, then take in your Compaftes each Flour feverally from the Scale of fx Hours , and mark them off in the Lines AD and BD; thro ’ thofe Points draw Lines from the CenterC, and they ftiall be the true Hour Lines required. For the Stile. Set A C from D to E, and continue it beyond the Center C, which fhall be the Stiles for the North and South Dial, as you fee done in the Dials.

Of the Ufe of the Scales in Platell. 91 By the Scale of Inclinations is known in eredl Decliners where the fubftilar Line will fall; which rnuft always be on the contrary Side the Meridian Line or Hour Line of 12; that is, if the Plane de- clines We ft ward the fubftilar Line mufc Hand on the Eaft-ftde, but if the Plane declines Eaftward ', then the fubftilar Line mud be placed on the Weft-ftde the Meridian: and if the Inclination of Meridians be lefts than 1 5 Deg. the fubftilar Line will fall be- tween 1 1 and 12, or between 12 and 1 a-clock, ac- cording to which Point of the Heavens the Plane declines: if the Inclination of Meridians be more than 15 Deg. but lefs than 30, the fubftilar Line will fall between the Hours of one and two, See. Some Dialifts put the Difference of Meridians of feveral Places, as Jerufalem, Madrid, Z§c. upon the Dial, tolhew theTime of the Day at thofe Places, as well as the Time where you are ; but this is needlefs ; for if at anyTime you would know what a-clock it is at any Place in the known World, when it is fuch a Time at London , only turn to the Table cf the Latitude and Longitude of Places at the End of this Treatife, and there fee what the Difference of Me- ridians is; and if the Place be to the Ead of London, add the Difference of Meridians in Lime to the Time at London , which gives theTime at that Place; but if it lie to the Weft, fubftradting the Difference of Meridians in Time from the Time at London, gives you the Time of the Day at that Place, Example.

See the Figure on Page io. You are to take notice, that the Parallels of the Signs, the daily Arches, the Circles of Altitude, and ail other Circles relating to the CourJ'e of the Sun, when they are defcribed upon zny Sun Dial, are not fbadowed out by the whole Stile, or Axis of the Dial as the Hours are, but by fome one Point in the fame Stile or Axis; as by a Knob, Button or Notch, filed in the Stile of the Dial, or by a Hole in a Glajs Window for proieBed Dials, or by a Piece of Look- ing-Glafs for ref e died Dials ; in all which Cafes the ‘Trigod a-tCis to be applied, fo that theLine thereof marked AB, muft lie upon the Stile of the Dial, or parallel to the Axis of the World, iF it*be an Hole in a Window, or a Piece ofLooking-GlaJs : And now, the Trigon being thus placed with the Equinoctial CD T perpendicular to the Stile, the Center being always fixed upon the But ton or Notch, cr Knob, fo that you may turn it about the Axis, as occahon fit all require. For 93 Chap. XX. Of the Ule oj the 1 rigon. For the Equinoctial. Now fuppofeyou would infert PxtEquinoclial in- to any Dial, (for one Rule ferves for all Planes.) Firf, put a Thread through the little Hole marked with o at arand — , tying a Knot on the Thread that it flips not through the hole in the Trigon ; then put the Center C to the Knob in the Stile, and the Side AB to the Stile itfelf: This done, extend the Thread over the Line CD till it touches the Dial Plane: that Point of touching fhall be oneYdint through which the EquinoSlial is to be drawn upon thePIane: Then turning theTrigon about, frill keep- ing the Line AB parallel to the Stile, extend the Thread till it touch the Dial Plane in fome other Point, and that ihall be another Point , through which theEquinobiialis to be drawn upon the Dial. And if your Dial be ail but one plain Superficies, two Points will be fufficient to draw the Equinoc- tial by, it being a great Circle of the Sphere, and confequently a right Line upon all plain Superficies, • But, If the Dial confifl: of more than one Plane, then rnuft you, in the fame manner as before, find two Points at leaf: upon each Superficies ; which you may eafily and fpeedily do by turning the Trigon about the Stile, and keeping the Side A B parallel thereto, extending the Thread over the Li tie CD v till it touch the Plane. For the Tropick of Cancer. In like manner ifyou would infert the Tropickof Cancer intoyour Dial, you muft put the Thread in the Hole at 22, and then spply the Center C to the 94 Of the Ufe of the Trigon. Chap. XX. Knob in the Stile, keeping the Side AB parallel to the Stile (as before) extend the Thread over the Line C 25 till it touch the Plane, and that Point of touch mail be one Point through which the Tropick of Cancer mull pafs. Again move the Trigon in the fame Poftion up- on the Stile of the Dial as occafion requires} extend theThread over thtTropickC^ till it touch thePlane, and that lhali be another Point through which the Tropick mull be drawn, and in this manneryou may find as many Points upon the Plane as youpleafe, and the more the better , for thefe Parallels will not be freight Lines, as the Equinoctial Line was, but conic or curved Lines, through which Points a Line being traced, with an even hand, fhall be the Tropick of Cancer upon your Dial Plane. For the Tropick of Capricorn. And in this manner may xheTropickof Capricorn, and all the Parallels of the other Signs (or any other Parallel of the Sim s Declination ) be drawn on your Dials, if firft you put the Thread through the re- Jpeclive Hole , and apply the Trigon to the Stile, and extend theThread over the Parallel of Declination till it touch the Plane ; and thus you may find as many Pointsasyoupleafe, thro’ which to draw your Parallels', and this may fuffice for the Infcription of the Parallels of the Signs of the Zodiack. And if you would infert the Parallels for the length of the Day, they are to be done in the fame manner, ifinftead of the Declinations for the Signs, you put into your Trigon thPParallels for the length of the Days you intend to infert into your Dial.

Concerning the Motion of the Hands of a Clock or W atch , as it re - prefents the Motion of the Sun and Moon. F OR aConclufion of this Work, I fliall here £hew my Reader how naturally the two Hands of a ClockotWatch reprefent the Motions of the Sun mid Moon: For as there are twelve Calendar Months, and twelve Signs in the Zodiack, fo alfo are there twelve Hours upon the Dial Plate of a Clock and Watch. But as the Moon makes thirteen Conjuncti- ons with the Sun in one Year, that is, in the Time the Sun apparently moves once round the Heavens, fo the Minute- Hand of a Clock or Watch makes but eleven Conjunctions with the Hour-Hand in the Time it moves once round. For let the Hour-Hand reprefent the Sun, and the Minute-Hand the Moon, at 1 2 a-clock they are always together, then they both moving forward, when the Minute-Hand comes again to 12, it doth not find the Hour-Hand there, but 1 26 Of the Hands cf a Clock , &c. Chap.XXV* but is moved one eleventh Part of the whole Revo- lution further; therefore the Minute-hand mu ft go 5 Min. 27 Sec. i6Tbirds, 2 1 Fourths, 49 Fifths T ‘- r , before it make the next ConjunBion with the Hour- hand. And Juft fo it is with the SunzndMoon ; for fuppoiing the new Moon; to be upon the 21ft Day of March in the very beginning of Aries , they both moving forward according to the order of the Signs. When the Moon comes again to the very beginning of Aries, llie doth not find the Sun there, he is mo- ved 26 Deg. 55 Min. 46 Sec. more to the Eafm the E clip tick,* fo that the next Conjunction of the Sun and Moon will be made in Aries 29 Deg. 6 Min. 25 Sec. 1 2Thirds, according to their middle Motions; and the next or J'econd new Moon would be made in Taurus 28 Deg. 12 Min. 50 Sec. 24 Thirds; the Third'm Gemini 27 Deg. 19 Min, 15 Sec. 36 Thirds; the Fourth in Cancer 26 Deg. 25 Min. 40 Sec. 48 Thirds, &c. every new Moon exceeding the Place cf the foregoing by 2 9 Deg. 6 Min. 2 5 Sec. 12 Thirds, but they do not move equally as both the Hands of a Clock or Watch. Therefore the above equal Law of the Sun and Moon is not exactly obferved; how- ever, this may ferve well enough to give an Idea of the new Moons, how it is nothing elfe but the pafs- ing of the Moon by the Sun, as the Minute-hand of a Watch doth by the Hour-hand, as reprefented by the following Table. * See my Umnojafla page 1 66.

Chap.XXVT. CHAP. XXVI. Of Painting Sun Dials, and fir ft of the Planes or Surfaces on which Dials are to he drawn. ~f\IA L Planes are of two Sorts \ fir ft, fuch as are made on the Wall of a Building ; or fiecondly fuch as are drawn on Tables of Wood, vulgarly- called Dial-Boards. The firjl Sort , if they are made on Brick- Work, is done by plaifteringon the Wall with Lime, Sand * and Hair, mixed; this muft be well drenched with Linfieed Oil, after it is dry, i.e. as long as it will drink any; and then painted with Oil andWhite- Lead, that it may be durable. But a better way is to temper the Lime, Sand and Hair with Ox Blood, which will be no great Charge, but of great Advantage ; for this Mixture will equal in Time the hardnefsof aFree-Stone, and keep the Surface as free from the Injuries of Weather; but you muft afterwards paint it white. The following Method is ftill preferable. To make an exceeding ft rang Cement or Plaifter, with which to form any Dial Plane upon the Side of a Houfe or W all, which will endure the Wea^ ther, not inferior to Stone. Take Lime and Sand, and temper it with Linfieed Oil to the Confifteney of Mortar, or common Plai- fter, and fpread it upon the Wall to a competent Thicknefs, and it will become as hard as a Stone, and laftmanyAges; and upon this you may defcribe a Dial, and put on the Lines, Figures and Furni- ture, as hereafter is directed. Note, Ch. XXVI. Of Painting Sun Dials, &c. 129 Note , If you are in the Country, remote from any Opportunity of getting Linfeed Oil , you may make it with jkimmed Milk, which will be much fuperior to Plaider made with Lime, H air andWater. If you are to draw a Dial upon a Stone , the belt Way is to drench the Stone with Linfeed Oil and White-Lead mixed very thin , till it will drink in no more ; then fhall the Dial you paint upon it, lad: longer, and be the better prepared againd the Ru- ins of Time. Now for Tables or Dial Boards of Wood, they being the mod: common, I fhall give fuch Directions for making them, as have been always found moil profitable and fit for the Purpofe. The bed: Woods for this Purpofe, are the clear efl Wainfcot, and yellow Fir , provided it is clear of dead Turpentine Knots ; there is not much Diffe- rence between thefe two Woods, as to their Alte- ration by the Weather, they being both fubjeft to fplit in cafe they are bound, and have not free Li- berty to Jhrink with dry Weather, and fwell with Wet, though as to their lading, Oak feems prefer- able; though good yellow Fir will iad the Age of an ordinary Man, if well fecured, as Things of this Nature ought to be. In working either of thefe Kinds of Woods, the Boards ought fird to be cut to fuch a Length as you intend your Dial Board thould be, and fo many of them as may make up the Breadth defigned, and let them be joined on the Edges, and plained on both Sides, and afterwards fet to dry. For it has been obferved, that though Boards have lain in a Houfe ever fo long, and are ever fo dry, yet when they are thus foot and plained, they will [brink afterwards beyond Belief \ if kept dry. K When 1 30 Of Painting Sun Dials, &c. Ch. XXVI. When yon think they are dry enough, and will fhrink no more, let them be (hot again with good Joints, and let every joint be fecured with wooden Dove-Fails, let in a-crofs the Joint in the Backfide ; let this be done after the Boards are glued together and well dried : after it has been thus glued, and the Joints are fufficiently dry, then let the Face of the Board be well plained and tried every Way that it may be both fmooth and true, and the Edges fhot true and all of a Thicknefs, as Pannels of Wainfcot are commonly wrought. The Edges muft be true and even, that they may fit into the Rabit of a Moulding, put round it, juft as a Pannel of Wainfcot does in its Frame. This Method will give Liberty to the Board to jhrink without tearing; whereas Mouldings that are nailed round the Edges, as the common Way is, do fo reftrain the Motion of the W ood, that it cannot jhrink without tearing ; but Boards made this Way will laft a long Time, without either parting in the Joints or fplitting in the "Wood. Dials are fome Times drawn on Planes lined with Copper or Lead, that they may be free from fplitting or tearing ; but a Board ( if it be made as before di- re Bed ) is to be prefered in many Refpedts. As firft. In that it is much cheaper. Secondly, Both Lead and Copper will fwell a little with the Heat of the Sun, and in Time will grow hollow outwards, or become convex inftead of a perfect Flat, which will much pervert the Truth of its Shadow. And, thirdly, The Colours will be apt to peel from the Metal, and the Dial will by that means be in dan- ger to be fooner defaced, than if it were painted upon a wooden Plane. Ch. XXVI. Of Painting Sun Dials, &c. 1 3 1 To make the belt Glue for gluing the Joints of Boards for Dials. Take a Quart of Milk (but fome have prefered Water) that has flood fo long and been fkimmed fo often that no more Cream will arife; and when Ikimmed very clean boil it a little in a leaden Pot , and if any fkum yet arife be fure to take it clean off 3 then put into the Milk about half a Pound of good Glue cut in fmall Bits, which will foon melt : boil it gently on a foft Fire to a good Body , but not to be too thick nor too thin 3 then take it off the Fire and keep it for Ufe. Note, Care muft be taken in the Boiling that it do not burn to the Sides of the Pot , for that takes away much of the Strength of the Glue; but if it be made with due Care, it binds beyond any other Glue, and it is better able to refill the Weather, and therefore the fitted: for gluing Boards for Sun Dials. Care muft be taken that your Glue be not made too thin, for if it be, the Wood will Jg drink it up that it will not be of a fujjicient Body to bind the Parts together 3 on the contrary, if it be too thick , it will not give Way for the Joint to Jhut clofe enough to be ftrongly joined 3 for though it is Glue that makes the Joints flick, yet where there is fo much of it that the Joint cannot dole ekadlly, it will never hold firmly. Whenever you ufe your Glue take care that it be thoroughly hot, for Glue that is not hot never takes firm hold on the Wood. You muft alio take great Care that the Boards you are to glue have not been touched with Oil or Greaj'e 3 for in fuch Places the Glue will never take hold, although after a Thing is once glued fail, no Greafe nor Oil can hu t it. 132 Of Painting Sun Dials, &c. Ch. XXVI. The Glue being ready, and the J oints of the Board Ihot true, fet both the Faces of the Joint clofe toge- ther, and both alfo turned upward-, then dip a Brufh in the Glue and befmearthe Faces of both Joints as quick as poffible , then clap the two Faces of the Joint together, and flide or rub them long ways one upon another two or three Times to fettle them clofe, and fo let them Hand till they are firm and dry. To prepare your Oil for laying on the Colours upon Dials. Take One Gallon of Linfeed Oil and fet it upon a Charcoal Fire , and when it is about to boil put into it two Pounds of Red Lead , and let it boil toge- ther for about an Hour-, but the belt Way to know when it is boiled enough, is to take a little of it out and let it cool, and then if it ropes like thin Tar, it is enough: This done, put a lighted Paper to it, and fet it on Fire to confume the greafy Part of it, which will be, done in a Minute or two, more or lefs, ac- cording to the Quantity of your Oil ; and when it has burnt long enough clap a Cloth or any other Thing clofe over it, and extinguilh the Fire; after which let it cool and fettle , then decant the clear Oil from the Dregs, and keep it in a Bladder for Ufe. This is called drying Oil, and with this the fe- veral Colours are to be ground in order to paint, fo as to endure the Weather-, but you muft obferve that your Colours are thoroughly dry before they are ex- pofed. The feveral Colours I ill all defcribe hereafter. N. B. The above Method of making the drying Oil has one Inconvenience in it, that it makes the Oil of a deep reddijh Colour, which in fome Cafes may alter the Nature and Beauty of fome Colours, as Whites, which are liable to become Fellow -, alfo Blues Ch. XXVI. Of Painting Sun Dials, &c. 133 Blues may by this Means become greenifa 5 to pre- vent which, in the preparing of your Oil , inftead of Red Lead ufe Letharge of Gold. Of Colours ufed in Painting Sun-Dials. TheColours generally ufed inPaintingS unDials are: For White , Cerufe and White Lead. For Black, Lamp-Black, Ivory-Black, Charcoal, and Sea-Coal Black. Forifo/,Red Lead, Vermillion and CinnabarLak. For Green , Verdigreafe. BovBlue, Indigo, blueBice, blueVerditer andSmalt. For Yellow, yellow Oker, and yellow Pink. For Brown , Spanifh Brown. With the above Colours you may compound Variety of other Colours, viz. An Aft Colour is made by mixing a little Lamp- Black with White. A Purple is made by mixing Cinnabar Lak and blue Bice. A Carnation is made by mixing Cinnabar Lak and White. A Green is made by mixing blue Bice with yel- low Pink. N. B. Any Blue and Yellow make a Green of fome Degree or other. A Light Blue is made by mixing blue Bice and White. A Lead Colour is made by mixing Indigo with White. A lively Grafs Green is made by mixing Verdi- greafe with yellow Pink. And by this Means may feveral other Colours be compounded and made lighter or darker at Plea- fure, as a little Pradlice will make evident. K 3 Vo 134 Of Painting Sun Dials, &c. Ch. XXVI. To prepare the Colours for Painting Sun-Dials. Before you proceed to the painting of Sun Dials in their feveral Colours, it is iirft neceffary that they b e primed, that is, painted two or three Times over with Oil, and Colour prepared for that Pur- pofe, to fill up the Cavities which may (after plain- ing) remain in the W ood, and to make it perfectly plain, and the more capable to receive and retain other Colours; and of all Priming Spanijh Brown is reckoned to be the chief; for, not to mention its Cheap nefs, it dries kindly , and gives the Oil a fuf- ficient Time to penetrate into the Wood: and con- fequently both refills the Weather, and alfo freely receives all other Colours which are laid upon it : it is of itfeif of a Horfe-fejh Colour , and (befides its Ufefulnefs in priming) is a "natural Shadow for Ver- milion, and may be made lighter or darker, accord- ing to the greater or lefs Quantity of White mixed with it; though in priming, it requires not any Mixture, but only the Oil itfeif. In preparing the Sfanifh Brown for priming, grind it very well with the afore-mentioned drying Oil, and make it for the firjl Priming fomewhat thinner than you would do it for painting, that it may more ealily penetrate into the Wood; which being dry, do it over a fecond Time with the fame Mixture, only mix it a little thicker ; and letting that dry, do it a third Time , mixing your Colour thicker every Time; and take Care in the Priming, not only to rub the Brufh with the Priming all over the Plane, both on the Back , as well as on the Fore- fide and Edges , the better to preferve it, but alfo to bd) it againft it, that the Priming may be fure to pierce into all the Cavities or Pores of the Wood : Ch. XXVI. Of Painting Sim Dials, &c, 135 Wood : when this laft Time of colouring with your Priming is dry, then colour the Face of the Plane over with white Lead , and when it is dry do it over again three or four Times more fucceffively, after each drying; and fo will the Face of your Plane be of a beautiful white Colour, and it wall alfo he iiiiti- ciently defended againft the Fuiy and Violence of the Weather for many Years j when the laft colour- ing of your white is dry, your Plane is ready for laying on the Colours, viz. painting the Hour Lines , or what Ornament or Furniture you think fit to have upon it. Observe as a general Rule, that priming is to be mixed or tempered thin , but Colours for Lines or Figures to endure the Weather, muft be tempered thicker , the better to refill the Fury of flormy or moill Weather. If you are only for making a common Sun Dial , thefe four Sorts of Colours will be Jujficient. 1. Spanifh Brown ; which prepare, and therewith prime your Dial, as before directed. 2. White Lead , well ground in Oil; with which, after the Priming is thoroughly dry , go over it three or four Times, letting it dry between every Time ; which not only makes a beautiful white Ground, but fortifies it yet more againft the Fury of the Weather. 3 . Lamp-Black , for drawing the Hour Lines and Figures. 4. Vermilion , for drawing the Parallels of De- clination, or what other Furniture you think fit to put upon it. The Spanifh Brown, Lamp-Black and Vermilion , are all to be ground in the drying Oil, defcribed in Page 132;' and for the White Lead, it is to be ufed in the fame Manner; only in making drying Oil K 4 , for 136 Of Painting Sun Dials, &c. Ch XXVI. for White Lead, inftead of Red Lead , ufe Litharge of Go/d, and proceed as before. But if you would have your Dial more rich, you muft firft confider, what Colours you refolve to have your Lines, Figures, ©V. to be, and upon what Ground your determined Colours will appear moft beauti- ful. As, 1. Gold appears beft upon a Blue Ground, and indifferently upon a Red. 2. Blue and Green appear beft Upon Yellow and White. 3. Red fets off with Yellow, White , Blue , or Green. 4. Yellow fets off with Black , Blue , and Red. Befides the Directions given already for prepar- ing and laying on common Colours, it will be ne- ceifary to fpeak of the laying on the more rich and beautiful Colours and firft of Gold. Yo make Gold Size, with which you dejign to lay on Leaf Gold. T ake yellow Oker, and grind it with Water on a Stone with a Muller, till it be very fine, and then lay it to dry , and grind it with the afore-mentioned drying Oil, as you -would grind other Colours, ob- lerving to put fo much of each, that it may be of a competent Stiffnefs to work well, and of fuch a Bo- dy, that it may fettle itfelf fmooth when laid on, but not fo thin as to run ; and take care to grind it very fine , and it will add the greater Beauty to your Gold that is to be laid on with it. Ch. XXVI. Of Painting Sun Dials, &c> 137 fo lay Leaf-Gold on an Oily Size, or to make any Lines , Figures, See. of Leaf Gold upon your Dial. Draw your Lines, Figures, or Letters, or what you think fit to have in Gold, with Gold Size, ( above-mentioned ; ) which dry fo, that when you touch it with your Finger it will flick a little to it, but the Colour not come off-, j for if the Colour comes off on the Finger, then it is not dry enough, and mull be let alone a little longer ; for if you fhould then lay the Gold on, it would drown it fo that it would be worth nothing ; and on the other Hand if the Size fhould be fo dry as to hold your Finger, as it were to it, then is it too dry, and the Gold will not take, for which there is no Remedy but new fizing : therefore you muft watch that it be not too wet or too dry. Then cut your Leaf Gold as near as you can, into the Form you would have it, whe- ther of Figures, Letters, Lines, &c. (taking care to cut it rather too large than too little -f) and with a flat Stick lined with woollen Cloth, firft rubbing it on your Cheek, or breathing on it, take up your Gold (fo cut) and put it upon the Size, and the Gold will leave your lined Stick, and cleave to the Size ; then prefs it down with Cotton, or Hare’s Foot, and take care that you make the Figures, Lines, or Let- ters, in the Gold Size-, and that you cut the Gold large enough to cover the Figures fo made in the Size; and when it is thoroughly dry, brufli off the loofe Gold, and the painting will remain beautiful, and be able to endure the Weather. Note further , That a Book of Gold contains 25 Leaves, each Leaf being three Inches fquare; the Price of each Book is Two Shillings at the Gold-Beater’s; one Book will cover 225 fquare Inches of Work; for fo many fquare Inches are contained in 25 Leaves, that are three Inches fquare, every Leaf containing nine fquare Inches fuperiiciai in Gold. The right underkanding of this will much guide you in judging how many Books of Gold will ferve to gild that Work, whofe fuf crucial Contents in fquare Inches may before-hand be known. 138 Of Painting Sun Dials, &c. Ch. XXVI. To lay on Smalt to make a fine Blue. When you have laid on what you think fit in Leaf Gold, take white Lead, mix it pretty ft iff With, drying Oil, and with a Pencil lay that on where you intend your Blue fliall be, and then put your Smalt in a fine Searce, and lift it on to the Dial, and with a Piece of Cotton dab it down upon the White before laid on, and when it is thoroughly dry, wipe off all the loofe Colour with a Feather, and blow off the Dull with a Pair of Bellows, which will eafily blow off all, except what fell upon the White before laid on to retain the Blue, which will be a very beautiful Blue. Of the Nature and Colour of fome of the principal Ingredients ifed in painting of Sun Dials. 1 . Ceruse and White Lead are the only Colours to be ufed in painting in Oil, and befides their Ufe- fuinefs in painting of Dials, Paint made up with them and Oil, is frequently made ufe of in painting Polls, Palifadoes, Gates, Doors, Windows, W ainf- coting, &c. and anfwers the End of Painting, both as to Beauty and Prefervation, for they dry well, and ftrongly refill the Weather 5 and if you would have them to dry yet more fpeedily, you may in the tempering put a little Oil of Turpentine , if it be with- in Doors-, but without Doers, it is better without, becaufe that does not fo well refill the Weather. 2. Lamp-Black is a good Black, if it be firfl burnt, then ground, and laflly tempered with Oil. 3 . Charcoal is a Black that will ferve for ordi- nary Ufesj it dries well, but gieat Care muft be taken that it be well ground. 4. Spanijh Brown ■, the bell is a deep bright Co- lour , Ch. XXVI. Of Painting Sun Dials, & c. 139 lour, and free from Stones, and being very well ground, is the beft for priming : It is of a Horfe Flejh Colour , and a proper Shadow for Vermilion. 5. Red Lead is a great Drier and Binder for which Reafon it is made ufe of in the drying Oil ; it refills the Weather as well as any Colour whatfoever. 6. Vermilion is a rich Colour, and of a good Body, but Care mull be taken that it be finely ground, even as foft as Oil , and then it will work extra- ordinary well : It is bell to buy it in the Stone, left you meet with fome that has been adulterated with Red Lead, or the like ; it is a perfefl Scarlet of it- felf, and may be altered to feveral Varieties, by mixing with other Colours. 7. Cinnabar Lak is a rich Crimfon Colour, and mull be very fine ground. 8 . Smalt is a very fine Blue , and it is beft to be firewed on, as before taught ; for if you work it in Oil, (though you walh it and mix it with 'White Lead ) yet it will turn black in Lime ; if you buy ?t to work in Oil, the finefi is beft, which is called Oil-Smalt. 9. Blue Bice is a pale Colour, and works well, though a little fandy. 10. Blue Verdi ter is not fo good a Blue as Bice and Smalt, though it may ferve in Dial-painting, where they are wanting ; but it is a little fandy, and apt to fade and turn greenifh. 1 1 . Indigo is a very dark Blue, and commonly lightened with White, when ufed in Painting, ex- cept in Shadowing j it grinds fine, and is very pro- per for the lafl Colour of Polls, Palifadoes, Doors, Windows, &c. for it refills the Weather, and pre- ferves the Wood. 12. Blue Balls are almoft like Indigo, but not fo good a Colour, nor will it endure fo long. 140 Of Painting Sun Dials, &c. Ch. XXVI. 13. Umber is a Hair Colour , it muft be very fine- ly ground, which to effect, requires a great deal of Labour; it dries and binds exceedingly, and is there- fore alfo very proper for painting without Doors, as Doors, Pallifadoes; if calcined in a Crucible, it is a natural Shadow for Gold , and fome other Colours. 1 4. Verdigreafe is a perfect willow Green , but may be altered at Difcretion, with Yellow , &c. but being very foul , it mult be mended or cleanfed, which may be thus done : Grind it fine , and put to it eight Times its Weight of Spirit of Vinegar, digefi till the Vinegar is tinged very green , then decant the Co- lour ; caft away the Faeces, and evaporate the Vinegar in a Brafs Vefica, fo have you a very good Verdigreafe at the Bottom , much more fine and valuable , then be- fore it was cleanfed ; it dries very ipeedily. 15. Yellow Oker, the Eng/ijh, the Colour of firefh Wheat Straw ; the foreign is of fomewhat a more deep Colour ; it is much ufed in common Painting, being ground very fine. 16. Yellow Pink is a greenijh Yellow ; it grinds well, and is good to mix with other Colours, to make a Green. Of thefe Colours fome require wajhing , as Red Lead, Blue Bice, Smalt, and Verditer, which is thus performed : Put the Colour into a glazed Veflel, and put thereto plenty of clear Water; walh it well, and (after a while) decant the Water; repeat this Work fix or feven Times ; at laft (the Water being but juft troubled) put it into another glazed Veflel, leaving the Dregs at the Bottom ; then put fome more Water into this fecond Veflel, and wafli it as before, till the Water, after fettling, be clear, and the Colour remain fine at the Bottom. Note, Ch. XXVI. Of Painting Sun Dials, &c. 141 Note , Before you take the Colour out of the Velfel, fpread it about the Sides of the VefTel very thin ; and when it is dry, it will Part of it fall down to the Bottom, which keep by itfelf; but that which flicks to the Sides of the Veffel is the bell, and is as fine as any Flower; that ftrike off with a Feather, and keep it for Ufe. The Colours that require wafoing being thus pre- pared, (or if they are thofe that do not require waffl- ing, they are done without) your next Work is to grind them , which is done thus : Take a Spoonful or two of the Colour you in- tend to grind . and put to it a little lij-ifeed Oil , (but be careful you put in too little rather than too much ; ) mix them together, and upon your Stone with a Muller grind them well, adding Oil by De- grees, as you fee it requires it, to make it like an Ointment, (always obferving that it grinds much better when it is thick , than when it is fo thin as to run about the Stone;) every now and then fcrape it up together with a thin Knife or Lanthorn-horn , to keep it at or near the Middle of the Stone, and fo continue to w'ork till you have ground as much as you have Occafion for; which done, clean your Stone by grinding Sand and Water upon it, and then wafh and dry it, and the Muller ; and when you go to make Ufe of it, mix it with drying Oil, till it be fo thin as to run freely from the Pencil, yet fo thick that the Ground may not appear through it, or to run w T hen it is laid on, and then it will be the more beautiful Colour, and better endure the W eather. CHAP. Note, Dials are not to be refreihed but by new Painting ; yet here take Notice, that I think it not convenient at all to lay new Colour- ing upon the old Ground of a Sun Dial, (that is, to draw the old Lines and Figures over again in the fame Pollute, wherein they were 142 Of Painting Timber Work. Ch. XXVII. CHAP. XXVII. the Manner of Painting Timber Work "¥3 Y 'timber Work I mean all Manner of Wain- J 3 fcot, Doors, Windows, Pofts, Rails, Pails, Gates, Border-boards for Gardens, &c. to pre- ferve them from the Violence of Rain or Injury of the Weather ; the Method of doing which, I ihall here lay down as plain as I can. Suppofe then that there be a Set of Palifadoes, or a Pair of Gates , or fome Pofts and Rails to paint, and I would finifti them in a Stone Colour ; firft look over the Work, and take Notice whether the joints be open in the Gates, or whether there be any large Clefts in the Pofts ; for if thefe are not fecured, the Wet will iniinuate itfelf into thofe Defeats, and make the quicker Difpatch in rotting the whole Work : Let the firft Bufinefs therefore be to flop up thefe drawn before) but rather to take the Declination a-new, and accord- ing thereunto make a new Draught of your Dial, and proceed in the painting of it, in all Refpedts, as if it were a new Dial; for it is ob- ferved, that Dials which were made many Years, as thirty or forty Years ago (which we believe went true when firft made) will not give the true Hour now, but go very.falfe, which is caufed by fome fecret Motion of the Earth, not hitherto taken Notice of, which apparently alters the Declination of all Planes whatfoever. If any one requires more Satisfaction herein, let him repair to fome old Dial that was made many Years ago, and according to the Diiiance of the Su bitile from the Meridian, let him find out the Declination when frit mrde, as any Man that is an Artift can eafiiy do ; then let him take the Declina- tion of the Plane by the Sun, and he ihall find thefe two Declinations to differ considerably, according to the Number of Years contained be- tween your Ohfervation, and the Time of the Dial’s firft making : So that a Plane that flood full South thirty, forty, or fixty Years ago, ihall now decline fome Degrees either to the Eaft or Weft, according to the Nature of the Earth’s Motion, which is that which is called the Variation of the Comp of s , which is found by Gbfervation to differ much in the fame Country, in the Space of fifty or fixty Years, as all fkiiled in Aftronomy very well know. Places Ch. XXVII. Of Painting Timber Work. 143 Places fmooth and even with Putty, which is made of Whiting and Linfeed Oil, well beaten together on the grinding Stone, or with a wooden Mallet, to the Coniiftence of a very ftiff Dough, and with this let all the Crannies, Clefts, and other Defefts be per- fectly filled up, that it may be equal to the Surface or Outflde of the Stuff; then proceed to the priming of the W ork with fome Spanifh Brown well ground and mixed very thin with Linfeed Oil; with this do over the Work, giving it as much Oil as it will drink up; this in about two Days will be indiffe- rently dry: then, if you would do the Work fub- ftantially, do it over again with the fame priming Colour; when it is thoroughly dry, then take white Lead well ground and tempered up, but not too thin, for the Jliffer you work it, if it be not too ftiff, the better Body will be laid on ; and the longer it will laft : let the Colour be well rubbed on with a large Briftle Brufh, and the whole Surface of the Work be fo entirely covered, that there remain no Crack nor Corner bare, which you may eafily do by jobbing in the Point of a Briftle Brufh. : Let this firft Colouring dry, and then go over it a feccnd i Time , and if you pleafe a third alio : the Charge will be a little more, but the Advantage will be great in the Duration. This Courfe is fufficient for any Kind of Timber Work that requires only a plain Colour, whether you thus cover the Work v/ith a Stone Colour, or elie with a Timber Colour in Um- ber and White, or a Lead Colour with Indigo and White, that with White being cheapeft of the three by much : nay I have known fome lay over their Work only with a Coat of Spanijh Brown, by tempering it up more ftiff than was done for the two firft Primings, which in fome Refpedts is cheapeft of 144 Of Painting Timber Work. Ch. XXVII. all, and preferves the Timber- perhaps as well as any. Now he that is able to bring the Work thus far on, has proceeded to the higheft Pitch of that vulgar Painting, that aims at Prefervation beyond Beauty, though fomething of Beauty is neceffarily included In this alfo ; but this is not all, for he that is ar- rived thus far, is in a fair Way to other Perfedlions in the Art of Painting ; but for the Painting of Wainfcot with its proper Shadows, and for imitating Olive and Walnut Wood , Marbles , and fuch like, thefe mult be attained to by ocular Infpedtion ; it being impoffible to deliver the Manner of the Ope- ration by Precept without Example ; and I am bold to affirm, that a Man fhall gain more Knowledge by one Day’s Experience, than by an Hundred fpent to acquire it fome other Way. I advife therefore all thofe that defire an Infight into this Bufinefs, to be a little curious, if Oppor- tunity offers, in obferving the Manner of a Painter’s working, not only in grinding his Colours, but alfo in laying them on, and working in them, in all thefe obferving the Motion of his Hand, in the manage of any Kind of Tool, and by this Means, with a little imitation joined to the Diredlions here given, I doubt not but in a fhort Time you may arrive to great Proficiency in the Bufinefs of vulgar Painting. Note, That if when you have made ufe of your Colours, there be Occafion for a fmall Ceffation till the Work be finiffied, in this Cafe it is befi: to co- ver the Colours, if any remain in your Pots, with Water , for that will prevent their drying, even in the hotteft Time. And for your Pencils, they ought, fo foon as you have done working, to be well wafned out in clean Linfeed Oil, and then in warm Soap-Suds ; for if either Chap.XXVlI. Of Tainting Timber Work. 145 either Oil or Colours be once dried in the Brufh or Pencil, it is fpoiled for ever. It has been obferved, that Timber laid over with White , when it has flood fome Time in the Wea- ther, the Colour will crack and fir-ink up together, juft as Pitch does, if laid on any Thing that Hands in the Sun ; the Caufe of this is the Colour’s being- laid on with too Jiiff a Body , for being wrought too thick once, it will dry with a Skin on the Outfde , which will keep the Infde moift and prevent its binding firm, from whence thofe Cracks proceed. 5 Take notice , that if you fhall at any Time have occafion to ufe either Brufhes that are very fmall, or Pencils, as in many Cafes there will be occafion, you ought then to difpofe of the Colours you ufe uporr a Pallet , (which is a wooden Inftrument eafy to be had at any Colour Shop ;) and there work and tem- per them about with your Pencil, that the Pencil may carry away the more Colour; for you are to note> that if a Pencil be only dipt into a Pot of Co- lour, it brings out no more with it than what hangs on the Outfde , and that will work but a little Way, whereas if you rub the Pencil about in the Colour, on a Pallet, a good Quantity of Colour will be taken up in the Body of the Pencil ; and befides all this, you may work your Pencils better to a Point on a Pallet, than you can do in a Pot ; the Point of a Pencil being of greateft Ufe in divers Cafes, efpecially in drawing of Lines, and all kind of Flourifhing. I fhall flill be more particular under this Head of Painting, becaufe Painters Work is very expenfive, and is the only Part in Building wherein a Gentleman can be affifting either by himfelf or Servants, it be- ing almoft impoffible for any Gentleman to do either fylafons, Bricklayers, Carpenters, or Smith’s Works, L whereas j46 Of Painting Timber Work.

And that which conduces moft to this Pradiceis the vaft Difproportion between the Prices which Painters charge for their Work, and the Expence which Gentlemen are at in this Method of Painting, which at the utmoft doth not amount to one fourth Part of the Painter’s Price, to prove which I {hall fet down the Prices of Colours, and likewife fhew what Number of Yards one Pound of each Colour will paint.
