TO MEASURE CORN ON THE COB IN CRIBS 



(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 274S (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. 



Exa7nph\ — 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: iSo in. (length) X 60 in. (width) X 120 in. (height) 

 = 1,296,000 -T- 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 274S; the quotient 

 will be the number of heaped bushels of cars. Take two- 

 thirds of the quotient for the number of bushels of shelledcorn, 



HAY AND STIIAAV IN 3IOWS OR STACKS. 



Four hundred and fifty cubic feet of hay is roughly esti- 

 mated as a ton, but there is great variation in the ratio of 

 weight to volume, ranging from less than 400 to 500 cu. fi.^ 

 according to the kind of hay, time of cutting, and height of 

 mow or stack. In general, the finer the stalk of the plart. and 

 the larger the mow, 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; loose hay in 

 loft will take toward 500 cubic feet to the ton; in case of 

 timothy hay about 420, and in case of clover hay, about 500 

 cuiiic feet will make a ton. One ton of straw will measure 

 600-1000 cubic feet, according to kind of straw and length of 

 lime in stack or mow. The longer the time in stack, the 

 smaller the number of cubic feet per ton. 



In estimating by measurement, multiply together the fig- 

 ures representing the length, w'idih, and height of hay, and
