THE GRAIN HANDLERS. 193 



lows: Determine the length, width and height in inches, 

 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 uniform, 

 several measurements should be taken and their average 

 used. For example, the usual wagon-box is thirty-six inches 

 wide, one hundred and twenty-four inches long and sixteen 

 inches deep. Therefore, when level full, it holds, (36xi24x 

 16) divided by 2150, equals 33.22 bushels. This equals 2.07 

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

 forty-inch wagon-box will hold (40x124x16) 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 standard 

 weight, and when lighter or heavier, correction should be 

 made accordingly. The weight per bushel of grain and 

 seeds is given on the following page.
