SHEEP PARASITES IN GRASS 345 



through to the next enclosure. This they will early learn 

 to do, and so they will be eating the fresher parts of the 

 herbage in advance of the ewes. In 10 days then the 

 whole flock will go forward one pasture, the lambs yet 

 having access to the fresher feeding on ahead. Doctor 

 Ransom says we shall need for this sure treatment the 

 following divisions: For May, 2 pastures; for June, 4 

 pastures ; for July, 4 pastures ; for August, 4 pastures ; for 

 September, 3 pastures; for October, 2 pastures. That 

 makes 19 enclosures in all and insures that the flock shall 

 be kept in absolute freedom from infections throughout 

 the year. However, one will not absolutely need so many 

 enclosures as that. By June many of the lambs will be 

 ripe, by July many of the others, and even when the lambs 

 are born late, when managed in this way they should all be 

 ripe as peaches by the middle of August. After the lambs 

 are gone the ewes can be managed a little less carefully, 

 especially if they are in strong condition, though there is 

 a comfort in knowing that every stomach worm germ 

 that falls to the earth must die from lack of a host. 



To make this thing doubly successful put flat-bot- 

 tomed troughs in the pastures ahead, where the lambs 

 run, and put feed in them ; any sort of grain, corn, oats, 

 barley, bran, coarse-ground or broken cake or oilmeal. 

 Thus the lambs will grow like weeds and pay many 

 times over for their grain. Thus more sheep may be 

 carried on the same ground than would be possible under 

 ordinary treatment. There is scarcely any limit to the 

 number of sheep that can be safely kept on an eastern 

 farm under this system of management. The limit is, 

 of course, the size of the farm and the amount of grass,
