CHAPTER VIII-CALOULATIONS REGARDING EXCAVATIONS. 273
An example in illustration thereof. 62. In relation to the place known as vidyadhara-naghara, the breadth is 8, and the length is 12. The thickness of the surrounding wall is 5 at the bottom and I at tho top. Its height is 10. (What is the cubic measure of this wall ?)
Thus ends (the seotion on) the measurement of (brick) piles in the operations relating to excavatione.
Hereafter, we shall expound the operations relating to the work done with saws (in sawing wood). The definitions of torms in relation thereto are as follow :
63. Two hastas less by six angulax is what is onlled a kisku. The number measuring the courses of cutting from the beginning to the end of a given (log of wood) has the name of märga (or way).
64-66. Then, in relation to collections (of logs) of wood of not less than two varieties, consisting of teak logs and other such logs hereafter to be mentioned, the number of angulus measuring the breadth, and those measuring the length, and the number of märgas are all three) multiplicd together. The resulting product is divided by the square of the number of wigulus found in a hasta. In operations relating to Haw-work, this gives rise to a valuation (of the work as measured) in what is known 48) patřikās. In relation to logs (of wood) consisting of teak logs and other such logs, the number of hastus measuring the breadth and of those measuring the length are multiplied with each other, and (then) multiplied by the number of margar, and (thereafter) divided by the pattikäs as above determined; this gives rise to the numerical measure of the work done by means of the saw.
68 to 87. Kipku = hasta. Marga is the name given to any desired course or line of us wing in log of woud. The extent of the out surface in log of wood measures ordinarily the work done in sawing it provided that the wood is of definite hard nye sastmed to be of unit valge. This extent of the cat marface is menanred by means of special unit area which is called pati and is 96 angular in length and one kipku or 49 angul asin breadth. It io. owy to Ree that paffim is thus equal to seven square hastan.
