TO MEASURE CORN ON THE COB IN CRJBS. 



(Waring.) 



When the Crib is Equilateral. 



Rule. — Multiply the length in inches by the breadth in 

 inches, and that again by the height in inches, and divide the 

 product by 2748 (the number of cubic inches in a heaped bushel), 

 and the quotient will be the number of bushels of ears. Take 

 two thirds of the quotient for the number of bushels of shelled 

 corn. 



Example. — Required the number of bushels of shelled corn 

 contained in a crib of ears, 15 ft. long by 5 ft. wide and 10 ft. 

 high. 



Solution: 180 in. (length) X 60 in. (width) X 120 in. (height) 

 = 1,296,000 -f- 2748 = 471.6 heaped bushels, two thirds of which 

 is 314.6 bushels, shelled. 



When the Crib is Flared at the Sides. 



Multiply half the sum of the top and bottom widths in inches 

 by the perpendicular height in inches, and that again by the 

 length in inches, and divide the product by 2748; the quotient 

 will be the number of heaped bushels of ears. Take two 

 thirds of the quotient for the number of bushels of shelled corn. 



RECKONING OF AMOUNT AND VAX.UE OF HAY. 



Four hundred cubic feet of hay is roughly estimated as a 

 ton, but there is great variation in the ratio of weight to 

 volume, dependent upon the kind of hay, time of cutting, 

 and treatment in storing. In general, the finer the stalk of 

 the plant the heavier the hay ; also, of course, the more 

 closely packed in putting away, and the nearer the bottom 

 of the mow the heavier. Grass allowed to stand till nearly 

 ripe before cutting will be the lighter. 



In estimating by measurement, multiply together the fig- 

 ures representing the length, width, and height of hay, and 

 divide the product by the number of feet in a ton. For ex- 

 ample, if the hay is 40 ft. long, 16 ft. wide, and 18 ft. from 

 the bottom to the top of the mow, and the bulk agreed is 

 400 cub. ft. to the ton, the mow will contain 40 X 16 X 18,
