TABLE IX. - WEIGHT OF PRODUCE PEK ACRE. 315 



yard in the given dimension, the number at the top of the Tablo 

 is the number per acre. 



EXAMPLE 1. The average produce of a drill of potatoes has 

 been ascertained to be 4f pounds per yard, and the width of the 

 drill is 30 inches ; required the weight of the crop per Imperial, 

 Scotch, and Irish acre? 



Look in the Table under 30 inches, and 



Tons cwt. qr. Ibs. Tons cwt. qr. Ibs. Tons cwt. qr. Ibs. 



Opposite 4Hbs. stands 1113 112 1414 1 5* 18 18

EXAMPLE 2. A field of carrots is in drills 15 inches wide, and 

 the plants 10 inches apart in the drills ; the average weight of 

 the carrots in a yard in length of the drill, is 4 pounds; required 

 the number of carrots on an acre Imperial, Scotch and Irish, 

 also the weight of the crop per acre ? 



To find the number of carrots, divide the inches in a yard =r 3G 

 by 10 inches, the distance between each = 3^- = 3f = the 

 number of carrots in a yard of the drill; then multiply the num- 

 bers of each denomination at the head of the Table at 15 inches 

 by 3|; the product is the number of carrots per acre.
