l8j MANAGEMENT AND FEEDING OF SHEEP 



ordinarily practiced, but it should be the aim to have a re- 

 serve grass pasture for reasons given later (see page 183). 



The necessity for additional fencing increases with 

 the intensity of the conditions of the supplementary graz- 

 ing. Where the attempt is made to keep sheep almost 

 entirely on such grazing, a plan that in many instances 

 is entirely feasible, more or less of additional fencing 

 should be provided. When the flock is large, it would 

 probably be more economical in the end to have the 

 fences permanent that inclose these crops. Three to four 

 fields should be inclosed, and easy of access. These are 

 necessary to furnish succession in grazing, as each can 

 usually be made to grow two crops of grazing yearly. 



Where the flock is not large, the grazing may be fur- 

 nished by one field, long and narrow, if it can be so 

 secured, but it may serve the purpose better to have two 

 such fields separated by a lane. Narrowness in such in- 

 stances lessens the necessity for using large amounts of 

 movable fencing, which when in use, extends across 

 rather than lengthwise. It is also an advantage in plow- 

 ing when the cross fences are not in use. 



Many kinds of movable fencing have been introduced 

 and each is possessed of more or less merit, but none of 

 these is superior to that now described. As has also been 

 shown in Chapter II, it consists of panels made of wood, 

 which, when in place, are held so by the headpiece. Each 

 panel is composed of three boards 4x1 inches, and a 

 fourth one at the bottom 6 x I inches. The boards are 

 usually made 12 feet long. Across these horizontal 

 boards are nailed three slats 4x1 inches. The end slats 

 are nailed on the same side of the horizontal boards, and 

 back 6 inches from the ends of the same. The middle slat 

 on the other side of the boards is equally distant from 

 the ends. The ends of the second board from the top are 

 cut off flush with the outside ends of the crossbars. The 

 spacing between the boards commencing at the bottom
