multiply them together and divide the product by 2150,* 

 the number of cubic-inches in a bushel. The quotient will 

 be the number of bushels. Where the depth is not uni- 

 form, several measurements should be taken and their 

 average used. For example, the usual wagon-box is 36 

 inches wide, 124 inches long and 16 inches deep inside. 

 Therefore, when level full, it holds: 36X124X16, 

 divided by 2150 equals 33.22 bushels. This equals 2.07 

 bushels for each inch of depth. In the same manner, the 

 forty-inch wagon-box will hold: 40 X 124 X 16, divided 

 by 2150, equals 36.91 bushels, or 2.37 bushels for each 

 inch in depth. This method of calculating the quantity of 

 grain gives the correct result only when the grain is stand- 

 ard weight, and when lighter or heavier, correction should 

 be made accordingly. The weight per bushel of grain and 

 seeds is given on page 240.
