58 CORN IN CRIBS. 



height,=1296000-^274r8=4:71.6 heaped bushels, f of which 

 is 314.6 bushels shelled. Ans. 



NOTE. The above rule assumes that three heaping half 

 bushels of ears make one struck bushel of shelled corn. 

 This proportion has been adopted upon the authority of 

 the major part of our best agricultural journals. Never- 

 theless, some journals claim that two heaping bushels of 

 ears to one of shelled corn is a more correct proportion, 

 and it is the custom in many parts of the country to buy 

 and sell at that rate. Of course, much will depend upon 

 the kind of corn, the shape of the ear, the size of the cob, 

 &c. Some samples are to be found, three heaping half 

 bushels of which will even overrun one bushel shelled ; 

 while others again are to be found, two bushels of which 

 will fall short of one bushel shelled. Every farmer must 

 judge for himself, from the sample on hand, whether to 

 allow one and a half or two bushels ears to one of shelled 

 corn. In either case, it is only an approximate measurement, 

 but sufficient for all ordinary purposes of estimation. The 

 only true way of measuring all such products is by weight. 



When the crib is flared at the sides. 



RULE. 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 pro- 

 duct by 2748, and 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.
