METHOD OF 



Suppose a field to be in the 

 shape of the figure annexed, the 

 length in the middle being 148 

 yards, the end A B 88 yards, 

 the end C D 94 yards, and the 

 straight line B D 154 yards; the 

 distance from the straight line to 

 the curve at B nothing, at E 18 

 yards, at P 13 yards, and at the 

 end D, nothing: then, for the 

 content of the square part the 

 length is 148 yards, and the two 

 ends when added together make 

 182 yards, the half of which is 

 91 for the mean width. Again, - 

 for the curve, the length is 154; and the off-sets, 

 aforesaid rule, will stand thus
