BY-PEODUCTS OF THE FAEM 195 



ated with the average gasoline engine. Shelled 

 corn well cleaned should command a price equal 

 to the corn sold on the cob, and would in this 

 manner afford the farmer the same profit and 

 leave him the cobs, costing the labor and expense 

 of shelling which would not be large. Most all 

 farms have their feed mills, or they can be pur- 

 chased at a cheap price, which too are operated by 

 gasoline power. These mills will grind up cobs 

 into a fine matter that can be utilized for feed, 

 bedding or manure, or, as has recently been dis- 

 covered, can be with little trouble and skill mixed 

 with cement and molded into the best of lumber. 

 But if the cobs were ground and returned to the 

 soil, the farmer would receive five times the value 

 by such utilization than he receives from the pur- 

 chase and use of commercial fertilizers, and he 

 would save to his soils the valuable soil minerals 

 contained in them. No manufacturing plants 

 would despise such a utilization of its by-pro- 

 ducts. It would ever be on the alert to find them. 



Much care should be exercised in the utilization 

 of straw upon the farm, and it should never be 

 sold from any farm unless animal or green manur- 

 ing crops are substituted in its place. Its main 

 uses are for bedding and roughage for stock, and 

 is thus converted, not only into animal profit mak- 

 ing fat, but into another by-product, manure. 

 Utilized thus, greater profit is secured than in its 

 sale. 



The successful orchardman is ever on the alert 

 to work up into profit his by-products of unsalable 

 fruit. They are used into cider, vinegar, feed, etc.
