a triangle is formed, the sides of which are 12, 16, 20 and this triangle *is 

 a rectangular one ; a e stands at right angles on a c, and as it is just 12 padas 

 Long, e marks the place of the southeast corner of the vedi. The north east 

 corner d is found in the same way. 



With the same cords increased four times (i. e., their length multiplied 

 by five) the two western corners of the vedi are found. 



In this case a cord of 40 padas length is tied to the poles at c and b, 

 and marked at the distance of 15 padas from b. Then it is taken by the 

 mark and drawn towards the south into the position b g c. The result is a 

 rectangular triangle as above ; g marks the place of the southwest corner. 

 The same operation repeated on the north side gives f as the place of the 

 northwest corner of the vedi. 



Another method for the measurement of the vedi follows : 



The diagonal cord of an oblong, the sides of which are twelve and five, 

 is thirteen ; with these cords the two east corners are fixed. 



(See diagram III.) 



A pole is fixed at the distance of five padas from the east end of the 

 prachi, a cord of twenty-five padas length fastened at a and c, marked at 

 the distance of 12 padas from a, drawn towards the south &c, as above. 



"With these cords increased twice (multiplied by three) the two western 

 corners are fixed. 



The requisite rectangular triangle is here formed by the whole prachi 

 = 36, and by a cord of 54, divided by a mark into two pieces of 15 and 39. 



Another method follows : 



The diagonal cord of an oblong, the sides of which are fifteen and eight, 

 is seventeen ; with these cords the two western corners are fixed. 



(See diagram 4.) 



A pole b is fixed at the distance of eight padas from d, a cord of 32 

 padas tied to b and d, &c.

The diagonal cord of an oblong, the sides of which are twelve and 

 thirty-five is thirty-seven ; with these cords the two eastern corners are 

 fixed. 



A pole is fixed at c, thirty-five padas to the west from a ; a cord of 

 forty-nine padas tied to a and c, &c.
