SHEEP AS IMPROVERS OF CROP YIELDS 21

 factory where the management is judicious. 



There are, of course, some objections to grazing sheep 

 thus. One is found in the labor involved at a busy season of 

 the yean There is first, the work of preparing the land for 

 each successive crop and sowing it; second, the labor in- 

 volved, it may be, in cultivating some of the crops; third, 

 the labor of taking the sheep to and from the pastures, and 

 fourth, the work of removing and putting up frequently such 

 portions of the fences as are movable when movable fences 

 are used. 



A second objection is found in the outlay for fencing. 

 While it is, of course, practicable to introduce this system of 

 grazing on any arable farm and on any portion of it where 

 introduced on a large scale, the arrangement of the fences 

 with reference to the grazing is a matter of prime impor- 

 tance. When planning any system of grazing through grow- 

 ing crops in succession, the aim should be to secure one plot

 outlay for the cross fences, movable or otherwise, should 

 be relatively low. If two such plots or fields can be secured 

 with a lane between them, the conditions are so far im- 

 proved. There should be easy access to a grass pasture and 

 also to the sheds, as it is necessary to admit the sheep fre- 

 quently to the sheds or the pastures while they are being 

 thus grazed. In Figure i is shown a panel of movable fence 

 and the headpiece for the same. Each panel is composed of 

 three boards, 4x1 inches vyide and a fourth one at the bot-
