are devoted to permanent pasture. The stock kept are mostly cattle, 

 and they are kept on pasture much of the year. Barbed-wire fences 

 sufficient to turn cattle can be much more cheaply constructed than 

 woven- wire fences, and under the conditions prevailing here are 

 nearly as satisfactory. Even if a few steers are lost as a result of 

 wire cuts, their loss would go but a short way toward balancing the 

 higher cost of building and maintaining woven-wire fences.

RELATION OF SIZE OF FARM AND TYPE OF FARMING TO RODS OF 



FENCE PER ACRE. 



From an examination of Table 2 it will be seen that the amount of 

 fence used per acre is considerably less in Area jSTo. 4 than in the other 

 areas. This is due to the fact that much less stock is carried in pro- 

 portion to the size of the farms by the farms in Area No. 4. There 

 are many purely grain farms in this area which carry no stock other 

 than the necessary number of horses to do the farm work. Some of 

 these farms have a pasture fenced for their horses, and the remainder 

 of the farm is left unfenced. 



Table 2 also shows that as the size of the farm increases the number 

 of rods of fence per acre decreases. The smaller fence requirement 

 of the large farm is due first to the fact that less fence per acre is 

 required to inclose a large field than a small one; a square 10-acre 

 field requires 16 rods of fence per acre, while a square field of only 1 

 acre requires approximately 50 rods; secondly, the crop rotation 

 practiced on the small farm is usually similar to that of the large 

 farm and requires as many fields, therefore proportionately much 

 more division fence than is required by the large farm.
