the growing season and even those which do may require resting spells for re- 

 cuperation. Continuous'TJasturing and foraging by hogs is largely dependent on a 

 succession of these two classes of crops. As a small area can be made to produce 

 sufficient green crop for large numbers of hogs, this fact, in addition to the two 

 already stated, would seem to require either a number of small lots or one large 

 one subdivided by portable fences or hurdles. Portable fences constructed of 

 light lumber have been commonly used in the past, but this material is no longer 

 practicable under general conditions. If the number of hogs on a farm will

justify the growing of say six acres of forage crops, this should be enclosed and 

 divided through the center by permanent fences. Division of the two halves can 

 then be made by means of a portable woven wire fence as follows: Set a row of 

 posts two rods apart across each half for the support of the portable fence; owing 

 to the distance between the posts they will not interfere seriously with cultiva- 

 tion. Fig. 10 shows a contrivance devised for the attachment of a portable woven 

 wire fence at the ends. Two posts cleated together at both top and bottom about 

 four inches apart, are set in line with the fences at each end. If the woven wire 

 is stapled to the end posts firmly enough to hold it, the fence will be badly 

 damaged in withdrawing the staples to remove it, so that it would soon be de-
