CONCRETE SILOS 
Before and After a Disastrous Fire on farm of A. B. Main, Delaware, Ohio; adjoining barn contained 
180 tons of hay. Burned in Autumn of 1910; 530 tons of silage absolutely uninjured in silo, so that 
Mr. Main was not compelled to sacrifice 80 head of cattle which he was feeding at that time. The silo 
is 20x60 feet in size and was built by the Perfect Cement Silo and Cistern Co., Delaware, Ohio.
