172 SHEEP FARMING IN AMERICA 



There are two reasons for this: the one that it is 

 better for the grass, and thus in the long run better 

 for the flock, and the other that there is thus no con- 

 tamination of land over which the lambs will later 

 feed. If it were possible to wholly eradicate the 

 worms from the ewes by treatment this care would 

 not be needed, but unfortunately it seems almost im- 

 possible with our present knowledge to kill all of 

 the worms by any medication. Probably while con- 

 fined to the yard the lambs will be born. It is essen- 

 tial that the flock be well fed at this time so that 

 the ewes be full of milk. If desired there may be 

 provided a run to a rye field, or to some grass pas- 

 ture that will not be afterwards used that summer, 

 to help stimulate the milk flow. By May 15 probably 

 the grass will be so forward that the flock may be 

 turned out for good. Now begins the new manage- 

 ment. Instead of turning the flock to a large pas- 

 ture to roam over it at will turn them on a very 

 small part of it. How best to manage this will de- 

 pend upon circumstances. The writer thinks that 

 in our land of small supply of labor and much hurry 

 and turmoil during the summer season it is safest 

 to divide the pastures by permanent wire fences. 

 These are not costly and need not be very higH. We 

 will, then, turn the whole flock together into the 

 first division; none shall be scattered about. Of 

 course there may be two flocks, one with lambs and 

 a dry flock, but the dry flock had better be put apart 

 somewhere or else put with the ewes. It will not 

 do to let anything interfere with the regular rota-
