"Silage has very much the same effect upon the cow's digestive 
apparatus as pasture grass." — KimhalVs Dairy Farmer, Waterloo. 
"Every now and then some cock and bull yarn is started by ignorant 
men as to evil effects of ensilage. No one can stop them. They are a 
natural product of ignorance. Disraeli once said that 'even 
Buif Stories I^^o^idence could not provide for the unforeseen machinations 
of stupidity.' About once in so often we are called upon to dis- 
pute the statement that ensilage injures the teeth of cows. The latest 
tomfoolery of that kind is that ensilage causes acidity in the soil, and we 
notice Dr. Hart of the Wisconsin College of Agriculture feels called upon 
to dispute it. But the worthy doctor has an interminable task ahead of 
him if he puts down every ignorant tale that is told about the silo and 
about ensilage." — Editorial, Hoard's Dairyman, Ft. Atkinson. 
"It is more difficult to keep silage in a silo 24 feet deep than in one 30 
or 40 feet deep. The deeper the silo, the more likely the silage is to pack 
Dee Silos ^^8^^^^^ together and keep out air. In early days, when silos 
were made only 15 or 20 feet deep, they found it necessary to 
l)ut weights on top of the mass in order to prevent spoiling." — From 
Wallace's Farmer, Des Moines, Iowa.
