CONCRETE SILOS 
uses are being found for the silo and new crops successfully put up. 
Where a crop is in good condition there is no reason why it will not 
keep in a silo better than anywhere else, provided, of course, that the silo 
is air tight, and stays air tight. 
"Corn is universaUy recognized as the greatest of the silage crops. 
Its large yield of grain and fodder under fair conditions is remarkable. 
Corn, on bottom land farms, will produce from 6 to 20 tons of 
rn as milage per acre (in Oklahoma). The general average for Okla- 
homa is, however, much lower, ranging from 9 to 12 tons per 
acre. This wide difference indicates that for maximum yields corn should 
be grown on bottom land as far as possible, and kafhr and milo may be 
reserved for the upland." — KimbalVs Dairy Farmer, Waterloo.
