Cost of putting ten tons of silage into the silo, at 70 cents per ton. . 7.00 

 This includes all costs of machinery depreciation, as well as 

 horse and man lahor. 



Value of the stalks as they stand in the field 1.00 



Storage in an Iowa silo, at 23 cents per ton 2.30 



Total charge against the ten tons of silage $26.30 



Deducting the charges against this acre of silage, or ten tons, we 

 have left for the corn stalks a value of $13.70 an acre, and if clover 

 hay is worth $10 a ton, an acre of corn stalks from fifty bushel corn 

 land is easily worth this $13.70. Does it not pay to gather and put into 

 the silo a part of them? 



To determine the comparative value of silage and clover for two- 

 year-old cattle, and furthermore, to discover the best methods of feed- 

 ing silage, we have carried on quite comprehensive experiments at the 

 Iowa experiment station the past few years. One trial, especially that 

 of 1911-1912, in which five lots of ten steers each were fed, expresses 

 typically the general results of our experience. That corn silage is a 

 most acceptable and efficient fattening steer feed, the following figures 

 rlearly show: 



CORN SILAGE A PROFITABLE CATTLE FEED.
