GROWING CROPS FOR SUCCULENCE 71 



ners boarded across, and the inside sheathing 

 should run perpendicular at the bottom. Fourth, 

 the inside walls of stone, brick or cement silos 

 should have a final dressing of portland cement. 

 Fifth, silos should be located where it will be most 

 convenient to feed from. 



Calculating Size of Silo. The size of the silo to 

 build may be determined in any particular case 

 from the following data: A cubic foot of well- 

 packed silage will weigh on the average between 35 

 and 40 pounds, and this is about the amount that 

 should be fed daily to a dairy cow. If it is neces- 

 sary to feed cows for six months, or 160 days, one 

 cow will consume 180 cubic feet, or about 3*^2 tons 

 of silage. A herd of ten cows would consume 35 

 tons. However, there is always some loss by spoil- 

 ing and waste, so it would be better to figure on 

 about 40 tons. 



One acre of corn should yield 10 to 15 tons of 

 silage to the acre. The number of tons of silage 

 that a square or rectangular silo will hold may be 

 determined roughly by multiplying the length, 

 width and depth of the silo in feet, and dividing 

 by 50, the approximate number of cubic feet in a 

 ton of silage. A round silo 15 feet in diameter 

 and 20 feet deep will hold about 60 tons. The 

 same silo 25 feet deep will hold 80 tons. A round 

 silo 20 feet in diameter and 25 feet deep will hold a 

 little more than 140 tons. 



FILLING THE SILO 



Nowadays the corn binder is desirable for cutting 

 silage corn. It saves the expense of several men 

 and makes loading and unloading more economical
