CORN CULTURE 57 



This means that at the proper time a drove of hogs are 

 turned into the field and allowed to feed themselves upon 

 the corn. This method will work well only in cases where 

 there is a drove of considerable number, and when the 

 fields of corn are not too large. The field should be all 

 cleaned up in from two to four weeks after the hogs are 

 turned in, since rain and mud are likely to injure corn left 

 too long on the ground. 



It has been found by farmers who have made careful 

 tests of feeding corn in this way that more pork can be pro- 

 duced per bushel of corn when the hogs are allowed to feed 

 themselves from the field than when they are hand fed. 

 The labor of gathering and feeding the corn is also saved, 

 and manure evenly distributed over the field. Fences are 

 usually set up to divide the larger fields into small corn 

 lots. Twenty-six-inch woven wire is suitable for this use. 

 The wire is attached to well set, corner posts, and tightly 

 stretched. It is then tied to the corn stalks for posts. 

 This type of fence will last as long as is required for clean- 

 ing up the field. 



TOPICS FOR INVESTIGATION 



1. Good corn, if cut when glazing, should yield about 

 ten tons of silage to the acre. A ton of silage occupies 

 fifty cubic feet in the silo. If a silo is made to hold fifteen 

 acres of corn, and is built thirty feet high, what must be 

 its diameter? 



2. If a cow requires forty pounds of silage a day, and 

 the feeding season is one hundred and eighty days, how 

 many tons must be stored for twenty-five cows ? 



3. If the corn yields twelve tons of silage to the acre, 

 how many acres will be required for twenty-five cows? 



4. How many silos are there in your school district? 

 Of what are they constructed? What height and diameter 

 are they? Do any of them have a water-tank in the top? 

 vVhat did each of them cost? Draw a silo.
