A NEW METHOD OF CALCULATING THE CUBIC CONTENTS OF EXCAVATIONS AND EMBANKMENTS, BY THE AID OF DIAGRAMS. BY JOHN C. TRAUTWINE, CIVIL ENGINEER. PHILADELPHIA: it W, BARNARD & SONS, PRINTERS, 1851. Entered, according to the Act of Congress, in the year 1851, by JoimN J. RTnA'TwIn,, in the Clerk's Office of the District Court of the United States, for the Eastern District of Ponnsylvania. P T fil ACE Although the usual methods of obtaining correctly the cubic contents of Excavations and Embankments, cannot be said to involve any dc/iciulty, still they are certainly open to the objection of being very tedious. Consequently, any device for diminishing the labor, without affecting the accuracy, of the operation, may justly be regarded as a desideratum of some importance; and, in the belief, that the method by diagrams which I here propose, will conduce to that result, both in the field and in the office, I submit it to the notice of the profession. It originated with myself, several years since; but the want of sufficient leisure to reduce it to its present form, has hitherto prevented me from giving it publicity. Should an objection be made to the admission of the transverse ground-slope, as an element in'the Calculations, I can only reply that, practically, it is at least as accurate as that based upon the usual assumption, that the two outer heights or depths of a crosssection represent the exterior elevation of straight lines, drawn from those points to the centre stake. Sensible of the necessity of perfect accuracy in the Tables, I have prepared them all with the greatest care; and they have undergone so many revisions, both before and after being stereotyped, as to leave no doubt of their entire reliability. The paragraph commencing with "It is not absolutely necessary," page 8, applies only to approximate preliminary estimates; since the Rule which it contains is not mathematically correct; its error increasing with the degree of ground-slope. As remarked on a preceding part of the same page, new diagrams, and Tableg of Level Cuttings, must be prepared for new widths of roadway, when perfect accuracy is required. JOHN C. TRAUTWINE. Mr. Joseph Hufty, the enterprising Engineers' Stationer, No. 139 Chesnut street, Philadelphia, having proposed to me, that he would prepare a handsome copperplate engraving of Figure 3, for sale, on condition that I would secure a copy-right, and transfer it exclusively to him for a limited time, I have done so. Mr. Hufty's engraving will be found more accurate than paper ruled by the stationer's multiple pen; and will moreover exhibit the slopes, &c., which could not be effected by the ruling process. As this engraving will be required only in cases where the ground-slope cannot be regarded as uniform, throughout the width occupied by the excavation and embankment, it will rarely be necessary to use more sheets of it than there are miles in the length of the road. Its title is "Trautwine's Cross-section Diagram." Mr. Hufty will also print upon transparent paper, a diagram of Transverse Groundslopes, which, being laid upon a sheet of Figure 3, will give by in sp]ection, the horizon lal distances of the side-stakes fiom the centre. I have no other interest in these engravings, than the desire to facilitate a thorough testing of the merits of my plan. For merely obtaining Cubic Contents, the division of Figure 3 into squares, is not necessary; their use being confined to the determining of the side-distances. J. C. T. ERRATA.

A NEW METHOD CALCULATING THE CUBIC CONTENTS EXCAVATIONS AND EMBANKMENTS. There is but one correct principle upon which to calculate the cubic contents of excavations and embankments; and that is, by means of what is known as the Prismoidal Formula, or Rule. This Rule is as follows:.Jdd together the areas of the two parallel ends of the prismoid, andfour times the area of a section half way between and parallel to them; and multiply the sumv by one-sixth of the length of the prismoid, measured perpendicularly to its two parallel ends. Since, in railroad measurements, the prismoids are generally 100 feet long, it becomes easier in practice to multiply the sum of the areas by 100, (by merely adding two cyphers,) and to divide the product by 6; which amounts to the same thing as multiplying their sum by'th of 100 feet. The very general application of the prismoidal formula to other solids than such as are generally understood by the term "prismoids," has been shown by Mr. Ellwood Morris, Civil Engineer, in an able paper published in the Journal of the Franklin Institute. Vol. xxv, 2d Ser.p. 381. It embraces all parallelopipeds, pyramids, prisms, cylinders, cones, wedges, &c., whether regular or irregular, right or oblique; together with their frustra, when cut by planes parallel to their bases; in a word, any solid whatever, which has two parallel ends, connected together by plane or unwarped surfaces. In the cylinder and cone, the sides may be considered as consisting of an infinite number of indefinitely narrow unwarped planes. In railroad cuttings, it rarely happens that the ground surface lying between two consecutive cross sections 100 feet apart, is absolutely unwarped; yet, for practical purposes, it may very frequently be assumed to be so. When much warped, the cross sections must be taken closer together than 100 feet. There are generally two circumstances under which it is necessary to ascertain the cubic contents on a public work; viz: first, after a prelimi1 nary survey of one or more trial lines, for the purpose of determining approximately their actual or comparative costs; and, second, after the final adoption and staking out of the determined route, in order to know precisely the amount of work to be done. The measurements for the latter are performed with considerably more care, and attention to detail, than those of the former, inasmuch as upon them depend the payments to be made to the person who executes the work. They, moreover, involve considerations which cannot be attended to during a preliminary survey, without incurring an expenditure of time and labor, more than commensurate with the importance of the result. When the ground is level transversely of the line of survey, there is no difficulty whatever in ascertaining the contents from a table of level cuttings, previously calculated; but when the ground is inclined or irregular transversely, the calculations have hitherto been attended with considerable labor. The following method by diagrams, devised by myself during my probation as an assistant, and now communicated for the first time, will, I trust, be found to render the operations in the last cases nearly as simple and expeditious as in those of level ground; or., at least, infinitely more so than the usual ones. It dispenses with a great deal of calculation, and is, therefore, comparatively free from liability to error arising from that source. METHOD OF USING THE DIAGRAMS. The construction of the diagrams is extremely simple, notwithstanding that, at first sight, they appear somewhat complex. They are but few in number, since any particular road will generally require but three or four, which may be prepared by one person in a day or two. Before proceeding to explain the manner of drawing them, I wrill give one or two examples of their use, that the reader imay see the object aimed at, and to what extent it is attained. Example 1. Suppose that in a roadway of' 28 feet wide, and with sideslopes of 1~ to 1., the cutting at a certain station is 20 feet; and that the ground, instead of being level transversely, inclines at an angle of 15~. Turn to the diagram for a roadway 28 feet wide, with side-slopes of 1 to 1: place a finger on the centre line, at the height of 20 feet, and run it along up the curved line which commences at that point, until it strikes the inclined line marked 15~. It will be seen at once that the two coincide at the height of 22'8 feet: and this is the depth of the equivalent level cutting, which would have precisely the same area as the section under consideration. All such cases may therefore be instantly, and without any calculation whatever, reduced to others of equivalent level cuttings. This constitutes the main feature of the principle involved in the dia. grams. Had the depth been 20-3, or other decimal of a foot, the proceeding would have been the same as with the 20 feet; and the equivalent level cutting would be fbund on the inclined line 15S, at the distance of 3 of a foot (estimated by eye) above the curved line 20. E]xamrple 2. Using the same diagram; let the depth of cutting be 2 feet, and the transverse slope of the ground 20~. Here, placing a finger on the centre-line, at the height of 2 feet, and running it along the curved line commencing at that point, it will be fbund that before reaching the inclined line of 200, it encounters the dotted curved line drawn near the bottom of the diagram. When this occurs, we know that the ground-slope cuts the roadway, forming a cross section, partly in excavation, and partly in embankment, as in fig. 7. This is a most usefJt! check; for in such cases, the contents cannot be obtained by means of the diagram; but recourse must be had to a figure of the section, drawn for the purpose; as must also be the case when the ground is irregular transversely. A very simple method of proceeding, in all such cases, will be given further on. I trust that what has been already shown, will satisfy the reader that my method partakes of utility, as well as of novelty. On the page opposite each diagram, is a table of cubic yards for level cuttings, and for lengths of 100 feet. By means of this, the cubic contents may at once be taken out, when the equivalent level cuttings at both ends of a station are equal: but if they are not so, the prismoidal rule must be employed, thus: Suppose the equivalent level cutting at one end to be 20 feet, and at the other 25 feet. Then, that at a point half way between them would be 224- feet. Therefore, the cubic content will be equal to one-sixth of the sum of those corresponding to each of the two end depths, and four times that of the centre depth; that is, Cubic content by table ix, for ~0 feet depth 4296 cubic yards, e st 6"'C'a a25 " 6065 "s'~ Four times'" " 222 66 I 20584 or 4 times 5146 6)390945 Cubic yards contained in the station, 5157.5 It will be perceived that, instead of the areas correspondin:g to the difflbrent depths of cutting, or heights of filling, our tables give the cubic yards corresponding to those areas, for lengths of 100 feet. For the purposes of calculating cubic contents, these solidities may evidently be used instead of the areas; but for such cases as require the areas thermselves, a table of such is added. Its use will be shown further on. I will here observe, that for mere cozip'artive estimates of trIial lines, the labor may be much reduced by taking from the tables, the cubic content corresponding to the average of the equivalent level cuttings at the two ends. This mode is, of course, by no means mathematically correct, and should never be resorted to for final estimates; but it will frequently be sufficiently approximate (always a little deficient) for such trapezoids as occur in ordinary cuttings and fillings, wshere the depths at the two ends diff/e but a few feet. For instance, in the foregoing example, the correct contents of the station 20 feet deep at one end, and 25 feet at the other, were found to be 5157'5 cubic yards; while by this approximating mode, the contents of an average equivalent level depth of 221 feet, would be 5146 cubic yards; or but 11- yards less than the truth. In this manner, an entire cut or fill may be approximately estimated at one operation, by merely adding together all the average midway equivalent level cuttings or fillings, and dividing their sum by their number for an average one. Thus, if the average midway equivalent level depths of 6 consecutive stations of cuttings, were respectively 2, 5, 6, 4, 3, 7 feet, an average depth might be taken of 5+6+4+3'7 = 4'5 feet; and the cubic 6 contents taken from the proper table, for a depth of 4'5 feet, and multiplied by 6, (the number of stations,) would give the contents of the whole 600 feet, but slightly too little. METHOD OF PREPARING THE DIAGRAMS. I will now proceed to describe the mode of preparing the diagrams, for any width of roadway, and for any side-slope whatever. The determination of the principle on which they are formed, is left as a problem for such of the younger members of the profession as may choose,5 Y /t /n c to exercise their ingenuity upon it.

For example, if the side-slopes h e, gf, of the excavation or embankment, are I to 1, lay off (without any regard to the width of roadway,) the distances on the upper column of the table; if 1 to 1, those on the 2nd column, &c. This done, the scale of a b, as unity, will be of no further use. Distances on b c, intermediate of those in the table, may be inserted with sufficient accuracy by eye. Those beyond 200 will rarely be required, because, when the transverse ground-slope is great, retaining walls are resorted to as a matter of economy.

From o as a centre, lay off with a protractor, the several angles of transverse ground-slope as shown by the are in fig. 1. As before remarked, angles higher than 200 will seldomn be required. NoTE.-In fig. 1, the inclined lines, and also the angles on the arce are, for convenience, numbered only for every 5'; but in a working diagram they should be taken nearer together, for instance every, 20 to 3~. Lay a parallel ruler friom o to 5~ on the arc, and mark with a dot the point of intersection on the inclined line a 50; then keeping the ruler in the same position, move it upwards along o b, stopping at every division of 1 foot, and making corresponding dots on the inclined line a 5, as in fig. 1, continuing to such a height on the centre line as will include the greatest cutting or filling to be calculated by the diagram. Then lay the parallel rauler from o to 10~ on the are, and mark with a dot, the point of intersection on the inclined line a 100; then keeping the ruler in the same position, move it upwards along o b, stopping at every division of 1 foot, making corresponding dots on the inclined line a 10~. Then lay the parallel ruler from o to 150 on the are, and proceeding as before, make corresponding dots on the inclined line a 15~, and so on up to as high an angle as will equal the greatest transverse slope of the ground which occurs on the work to be calculated by means of the diagrams. Finally, connect the corresponding dots on the several inclined lines, forming thereby a series of curves, as shown in fig. 1, and also in our working diagrams. The diagram is now ready for use, for all cases of ground-slope which do not intersect the roadway, thereby forming a section partly in excavation, and partly in embankment, as shown in fig. 7. In order that the diagram itself imay inform us when this is the case, the dotted curve shown near the bottom of the working diagrams is added. It is prepared as follows: \ _= _ // Let a b, fig. 2, represent the C A --— ~f wVi(ldth of roadway, and c d the centre line of cuttings and fillings. From a as a centre, lay off with a protractor, the angles 50, 100, &c., and draw the lines a e, a/f; a g, &c., to the centre line. Now, suppose the height c e, corresponding to 50, to be 2 feet. Mark on the working diagram, the intersection of the curved line of 2 feet with the inclined line of 50~. Suppose the height cf corresponding to 100 to be 4 feet; and mark on the diagram the intersection of the curved line of 4 feet with the inclined line of 100; and so on with the rest. Then join their several marks of intersection, and the dotted curve is formed, and the diagram is finished. The working drawings which I have given, are on a scale of -1'th of an inch to a foot, for convenience of insertion in this volume; yet, although the curved lines are drawn straight across several divisions of the inclined lines, (generally 5 of them,) they will rarely be found, in operating with them, to differ as much as Jth of a foot from the truth. They are adapted to such widths of roadway as I judged most likely to be adopted in ordinary practice; viz.: for single and double track embankments, 14 and 24 feet wide on top, and with side slopes of 1- to 1; and for single and double track excavations, 18 and 28 feet wide at bottom, with side-slopes of from 1 to 1, up to 2 to 1P The widths will rarely differ more than 2 feet from those for which the diagrams have been prepared. The most mistaken economist would hardly venture to make them more than 2 feet less; nor do I conceive that any advantage would attend making them more than 2 feet greater. It is sometimes advisable to increase the quantity of excavation to be taken from a cut, in order to furnish earth for an adjoining embankment. When the value of land is not sufficiently great to constitute an objection, this may generally be most advantageously effected by merely increasing the side-slopes of the cut to 2 to 1; but, where that would not be sufficient, it becomes necessary to increase the width of the cut at bottom also, and separate calculations must be made for the purpose. No diagrams accompany the tables of level cuttings for side-slopes of ~ to 1, which are used only for rock; hecause with this side-slope, the transverse inclination of the ground rarely affects the quantity of material to an important extent. Still, on every work on which much rock cutting occurs, a diagram should be prepared for the purpose. Should other widths of roadway be adopted, new diagrams must be drawn for them; as also new tables of level cuttings calculated. These new tables may be easily made by merely adding to or subtracts ing from the contents corresponding to every consecutive -Tioth of a foot of depth in the tables of level cuttings, an additional'741 of a cubic yard, for each 2 feet of width added or subtracted. For example, suppose that the roadway, instead of 28 feet, is to be made 30 feet wide; with side-slopes of 1- to 1. Here, By the continual ad- Cubic Yards in a 30 ft.

It is not absolutely necessary to calculate new tables of level cuttings for widths differing 2 feet from those which I have assumed in the working diagrams. The contents of an excavation or embankment, may be taken from the nearest table, by means of the equivalent level cuttings deduced fiorn the diagrams; and an allowance be made afterwards for the 2 feet difference of width, by adding together all the average midway level depths, and dividing their sumn by their number, for an average depth of the whole. The number of cubic yards taken firom table 14, for this average depth, and a width of 2 feet, will, when multiplied by the number of 100 feet stations in the cut or fill, be correctly the amount to be added to, or taken from, the quantity previously obtained from the tables.:While the width of roadway remains the same, a separate diagram is required only for each side-slope; so that when the roadway has the same width in cuttings, and on embankments, with side-slopes of 1~ to I in both, but one diagram is necessary for the entire road. But, generally, the roadway is wider in the cuts than on the embankments; requiring at least one diagram for embankments, with side-slopes of 11 to 1, and one for excavations, with such side-slopes as may be adopted. Frequently one will be required also for rock cuttings, of to 1; and if different side-slopes of excavation are employed in different kinds of soil, a diagram must be prepared for each side-slope. An entire set for any particular road, may be completed by a ready draughtsman, in a day or two. CASES OF GROUND IRREGULAR TRANSVERSELY. All cases of irregular transverse ground-slope, (except that in which the ground-slope intersects the roadway, as in fig. 7,) may easily be reduced, by drawings, to such a form that their equivalent level cuttings may be obtained by means of diagrams, and the corresponding contents taken out from the tables. For this purpose, it is very convenient to have paper of about 14 by Fig. 3. 24 inches, ruled across in both ct directions, with parallel lines.......i''-.......................... about i- of an inch apart, as in....i...................................................................I..... ~ 1,.X..........6'.......................

Those flat rulers which move on rollers are greatly preferable to those with hinges, which invariably get out of order in a short time. The ruled paper is prepared by drawing upon some sheets, outlines of the side-slopes of an excavation, with a small piece of embankment below it, as in fig. 3; and upon others, the side-slopes of an embankment, with a small piece of excavation above it. The heights, or depths, should be numbered along the centre line, as in fig. 3. Finally, lay off on both sides of o as a centre, by means of a large protractor, single degrees up to as high as the greatest transverse ground slope for which the paper is to be used; this, as before remarked, will rarely exceed 200; because, with high transverse ground-slopes, it is generally. better to resort to retaining walls. The paper is now ready for use, and all the subsequent operations may be performed by the parallel ruler. One sheet may be made to serve for the calculations of many stations, by merely drawing in the transverse ground slopes, very lightly, with lead pencil marks, which may be rubbed out as each station is finished. It is advisable, however, in very irregular sections, to represent but two consecutive ones on one sheet; and after having drawn them in ink, and added the numbers of the sections or stations to which they belong, as well as the cubic content comprised between them, to lay them aside for future reference, in case of dispute with the contractor, after the work is commenced. The method which I advise for reducing irregular cross sections to equivalent regular ones, vwhich may be calculated by means of the working diagrams and tables of level cuttings, is as follows: CASE 1.- When the grounzd slopes differentlyfiom the centre each way, as e d,1 e a, infigs. 4 and 5. Fig. 4. Fig. 5. On the prepared paper, fig. 3, from the centre height or depth e, figs. 4 and 5, and by means of the parallel ruler, and the degrees marked on the sheet, fig. 3, draw the two slopes e d1 e a, figs. 4 and 5; the inclina2 10 tions of which are taken from the field slope-book. Draw e f parallel to a d, and join a.f. Then is a b cfequal to a b c d e,' figs. 4 and 5. Find by means of the parallel ruler and the degrees marked on the paper, the slope of a f; and with that slope, and the new centre depth n n, (which is had from the figure by inspection,) use the proper diagram for finding the equivalent level cutting; and take out the cubic yards from the table. Also, in fig. 5, the trianglesf e cd, andf e a, being on the same basefe, and between the same parallels fe, d a, are equal to each other; and leaving out from each the trianglef e o, which is common to both, we have the triangle f o di, e o a, and consequently a b cf= a b c d e.

If ithe trianole of excavation at the other end of the 100 feet station has the same area, the number of cubic yards corresponding to this area for a length of 100 feet will be taken from table 15. Also multiply a o by ef, and half the product will be the area of the triangle of embankment a, o e. If the triangle of embankment at the other end of the 100 feet station has the same area, the corresponding number of cubic yards will be taken fiom table 15. But if the triangles of excavation, (or those of embankment,) at the two -5Proof.-The two triangles a d f, a d e, fig, 4, being on the sanme base c d, and between the salme parallels a d and e f, are equal to each other. Leaving out firom each, the triangle a ci o, which is commnon to both, we have the triangle d f o, equal to the triangle ( C 0; and coni-euently ab cf is equal to a b c d e ends, are not of the same area, the trapezoidal rule must be employed, as in the case of trapezoidal cross sections of unequal areas. See page 3. That is, we must add together the contents corresponding to the two end triangles, and 4 times that corresponding to the triangle half way between them, and divide the sum by 6, for the true content. The base of the centre triangle of excavation, will be the average between the two bases a b, fig. 7, at the ends; and its perpendicular, the average between the two perpendiculars c d, at the ends. In like manner, the base and perpendicular of the centre triangle of embankment, will be averages of the two end bases a o, and of the two end perpendiculars eft If from irregularities in the ground, in the directionl of the line of the road, it should become necessary to take cross sections nearer together than 100 feet, only the same proportional parts of the cubic yards rmust be taken from the tables; and on this account, it is better always, when possible, to subdivide the 100 feet station-distances into such parts as will furnish numbers easy to divide by; thus, if the station be divided into 10, 20, 25, or 50 feet distances, they will furnish respectively the numbers 10, 5, 4, or 2, by which to divide the cubic yards in the tables, all of which are calculated for 100 feet distances. TO FIND THE DISTANCES OF THE SIDE ST AKES FROM THE CENTRE STAKE. In all. cases in which the cross sections are drawn, as just described, these disances may be had by measurement on the figures. But they may be obtained much more rapidly thus: prepare a piece of tracing paper,as in fig. 8, of the same size as the ruled paper on which the cross sections are drawn. From c as a centre, lay off and number the degrees above and below a b, as marked at the ends, to as high as the greatest transverse ground slope in the work. Also, from c as a centre, draw by the same scale as the ruled paper, fig. 3, arcs of circles one foot apart, and number them with their distances from c in feet. Then, by laying this paper upon a cross section of the road, fig. 3, with c of fig. 8, placed at the Fig. S. given centre height or depth on _ the line a a, of fig. 3, we at once read off; without any calculation whatever, the distances of the side stakes from the centre stake, ID',,,' measured along the transverse d -,' ground slope. These distances s' — will be copied into the proper,,, book for field use. If, instead of concentric arcs, vertical straight lines are drawn 12 on the transparent paper, we shall in like manner obtain, by mere inspec-. tion, the horizontal distances of the side stakes from the centre one. When the horizontal distances are used in preference to those measured along the transverse ground slope, it is necessary to use a plumb at the end of the measuring line, in order to hold it vertically over the centre, or the side stake, depending upon which is lowest. The tracing paper figure should be pasted to a frame, so as to lie flat on fig. 3. The frame may be of stiff pasteboard. ON THE USUAL METHOD OF CALCULATING EXCAVATIONS AND EMBANKMENTS. Different engineers employ different methods, of which the following is, perhaps, as simple as any: Fig. 9. Fig. 1O, e -, ct a It requires that there shall be given, (beside the width of roadway m n-, figs. 9 and iO, and the side-slope,) the extreme horizontal width a b of the cut, or embankment; and the vertical depthsf e at the centre; and c a, d b at the sides. The Rule then is, multiply the extreme horizontal width a b, by half the centre depth f e; also multiply ONE-FOURTH of the width of roadway m n, by the sum of the two side depths c a and d b: the sum of the products will be the area of the cross section m n d f c, fig. 9 or fig. 10. This area, thus found, multiplied by 100, (the usual length of the station in feet,) and divided by 27, (the number of cubic feet in a cubic yard,) gives the cubic content of the station, provided the area of the cross section at the other end of the station be the same; but if not, the prismoidal Rule must be used, as already explained. The trouble of multiplying by 100, and dividing by 27, may be avoided by the use of table 15, which I have prepared for that purpose. The centre depthsf e, fig. 9 and 10, are given by the level book; but the side depths c a and d b, have to be found by trial on the ground. USUAL METHOD OF FINDING SIDE-DEPTHS, AND PLACING SIDE., STAKES. The level is placed conveniently for sighting from the same position upon f, c, and d. A sightf o, is then taken on the target rod held atf; this sightf o, being added to the centre depth f e, gives the height e o, of the instrument above a b; or the horizontal plane, (represented by h p,) through which 13 the line of sight passes as the telescope of the level is swept round on the axis of the instrument. The height of d abovef is then estimated by eye, say at 2 feet; this 2 feet, added tof e, gives the approximate height of d b. Assuming the approximate height d b as the correct one, we find what would be the horizontal distance from the centre to d, either by calculation, or from a previously prepared table of horizontal distances. Measure off that distance horizontally towards d, and placing the target 2 feet lower on the target rod, hold it at the end of the measuring distance. A sight is then taken with the level, and if it strikes the centre of the target, it proves that the assumed height of d, and the corresponding horizontal distance from the centre of the roadway, were correct; and that the proper spot is found for placing the side-stake d. It seldom happens that such a coincidence is found at the first trial; at least two trials are generally required; and frequently three, or even four when the ground is extremely irregular. A very close approximation, however, can always be made by an experienced leveller after the first trial. An error of an inch or two in the position of a side-stake is a matter of no practical importance whatever. The same operation is performed at c, except that as c is lower thanf, the target is raised on the rod, as far above the sight taken atf as c is estimated to be belowf. (When putting in side-stakes for an embankment, the sight taken on the rod at the centre stake, is subtracted from the centre height of the embankment, in order to obtain the depth of the instrument below the roadway.) It is plain that if the height on the target rod at d, fig. 9, be subtracted from e o, the remainder will be d b; and that taken at c, subtracted from e o, will give c a. These operations give us therefore, at the same time, the heights d b, and c a; and also the horizontal distances from the centre to each side stake. All these are at once entered into the proper field-book, to be used in estimating the areas and cubic contents in the office. The sum of the two horizontal distances manifestly gives the extreme width of the excavation or embankment. It is evident, that in the time required for a leveller and rodman to ascertain the positions and heights of the side-stakes, at a single station, by this method, those of several stations could be found by one person in the office, by mine. Still, in some rare cases, where the ground-slope is extremely irregular, as among jagged rocks, the mode by the level is the only one proper to be used; as, in that case it would be impossible to take the transverse ground-slopes with any degree of accuracy. Transverse ground-slopes are obtained in the field with great facility, by means of a small slope level, or clinometer, placed upon a rod, 10 or 12 feet long, which, at every station, is laid upon the ground as near at 14 right angles to the line of survey, as can be judged by eye. These clinometers are sold by most of our principal instrument makers. When the ground is regular transversely, but one slope need be taken; at other times, one may be required from the centre each way; and rarely, more than one on each side of the centre-stake. The slopes for estimating the final adopted line, must be taken with much more care than during preliminary surveys of trial lines. They need not, however, extend beyond the widths actually occupied by the cuttings and fillings; while those taken in preliminary surveys should comprise a considerable width, as they are, moreover, used in the office for changing the position of the surveyed line, in order to avoid excavation and embankment. In the following tables of level cuttings, the left hand vertical column contains the height or depth of the embankment or excavation, in feet; and the upper horizontal column, the intermediate tenths of a foot. Thus in table 1, the cubic yards in a station 100 feet long and 10 feet deep, are 1074; for 10'1 deep, 1090; for 10'2 deep, 1107, &c. 1 -- 5 1 - iLO ->:. i t (8~ chill 5 i 5 I /' / /: 75:::.............................: o:~~~~~~~~~~~-i 15 TAnLE 1.-LEVEL CUTTINGS.

Of cubic yards in a 100 foot station, to be added to, or subtracted from, the quantities in the preceding thirteen tables, in case the excavations or embankments should be increased or diminished 2 feet in width. The most rapid method of performing this operation would be to add together the average heights, or depths, of the equivalent level cuttings or fillings of several consecutive 100 foot stations, and divide their sum by their number, for an average one of th:em all. The number of cubic yards corresponding to this average height, or depth, when multiplied by the number of stations, will give the content of the entire length, nearly. It would, however, be better for the assistant, in cases where the width of roadway differs from those in the preceding Tables, to construct at once a new table.

This Table shows the number of cubic yards of Excavation, or Embankment, corresn ponding to different areas of cross section, and to a length of 100 feet. The areas are expressed in square feet. This Table may be extended, by mentally changing the place of the decimal point; thus, the cubic yards corresponding to area of 1100 square feet will be 10 times that of 110 square feet, or 4074; those corresponding to an area of 8955 square feet will be 10 times that of 895'5 square feet, or 33167. If the number is not exactly divisible by 10, we may still take out the corresponding cubic yards with sufficient accuracy for practice, by using the nearest tabular number; thus, if we take 33167 for the cubic yards corresponding to an area of 8953 square feet, the error will be but about 8 cubic yards in 33000. A mean can, however, always be estimated in an instant by the eye, which will reduce the error to still less; thus it is seen at a glance, that 33157 is, in this instance, nearer than 33167. Area.
