TOBACCO FOR SHEEP ON GRASS 341 



and a half ounces or more of coaltar dip diluted with 6 

 ounces of water and administered to a ewe is said 

 effectually to rid her of stomach worms. Scouring ewes 

 may infect through soiling of the teats. Some shepherds 

 practice separating the ewes and lambs each day, put- 

 ting them together in the yard at night and the ewes in 

 one field and the lambs in another. This has given clean 

 and thrifty lambs. 



Sown Pastures for Sheep. The most practical thing 

 perhaps is to use only sown pastures for sheep. There 

 seems little danger of infestation when ewes and lambs 

 graze rape or red clover or oats or vetches. The reason 

 for this immunity is probably that the animals do not 

 graze so close to the ground as when on bluegrass or 

 other permanent grasses, so do not so readily take in the 

 worms or germs. Even here there is fear lest the sheep 

 have access to small plots of old grass, maybe along 

 fences or in yards to which they are given access and 

 which though small in extent may infect all the grazing 

 animals. When one is turning to fresh and clean pas- 

 ture one must strictly avoid letting animals have access 

 to old and infected spots. 



Feeding Tobacco to Sheep on Pasture. Tobacco feed- 

 ing has come into favor and seems to have much merit. 

 Tobacco will not always eradicate worms in a sheep, 

 but it will often serve to prevent their lodgement. One 

 can use stems or "trash" or any waste tobacco. There 

 is no fear of their eating too much ; they should be given 

 all that they will take. I have found that to dip the to- 

 bacco in not very strong salt water, taking out at once 

 and putting it in boxes where the sheep can have access to
