The volume is first found by the approximate method of avenging end areas, to which can be added, if desired, a correction due to the strict prismoidal formula, or a correction due to a modification of it for irregular ground. This separation reduces the labor, if both parts are computed at once, while it allows of computing only the approximate value at first, which will answer for all purposes except the final estimate, leaving the prismoidal correction to be computed at leisure on those volumes only where it is large enough to be appreciable.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cspan style=\"font-family:Calibri;font-size:1.0em;color:#000000;font-weight:normal;font-style:normal;text-decoration:none;\"\u003eThe Table for \" Volume by Avenging End Areas,\" is a table for triangular prisms, and it will give the approximate volume of triangular prismoids in cubic yards for a length of one hundred feet, between the parallel triangular ends, by taking the sum of the two numbers found with the base and altitude of each of the two end triangles as arguments. The table is thus independent of side slope, or width of roadbed, and will apply to borrow pits, trenches, etc., by dividing up the cross sections into triangles and trapezoids.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cspan style=\"font-family:Calibri;font-size:1.0em;color:#000000;font-weight:normal;font-style:normal;text-decoration:none;\"\u003eThe method of dividing up the sections for three-level, five-level and irregular ground, while not essential, is believed to give the least labor in computing, either with or without tables.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cspan style=\"font-family:Calibri;font-size:1.0em;color:#000000;font-weight:normal;font-style:normal;text-decoration:none;\"\u003eThe method for irregular ground is due to J.

By using A. M. Wellinghton's method for irregular ground, that for the purposes of the prismoidal correction only, the ground may be called regular, the correction is easily and quickly applied, to three-level, five-level, and irregular ground. It may be noted that when either the bases or altitudes of the end triangles are equal, the correction diappears.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cspan style=\"font-family:Calibri;font-size:1.0em;color:#000000;font-weight:normal;font-style:normal;text-decoration:none;\"\u003eWhile quantities are only given for full feet the corrections for tenths are easily taken out from the margin without multiplication and can be added mentally with but slight increase of labor.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cspan style=\"font-family:Calibri;font-size:1.0em;color:#000000;font-weight:normal;font-style:normal;text-decoration:none;\"\u003eThe Tables have been carefully recomputed in print, and it is confidently believed they are free from errors.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\n\u003cdiv style=\"text-align:left\"\u003e\u003cspan style=\"font-family:Arial;font-size:1.0em;color:#000000;font-weight:normal;font-style:normal;text-decoration:none;\"\u003eAll pictures are of the actual item.  If this is a railroad item, this material is obsolete and no longer in use by the railroad.  Please email with questions.
