218 BRITISH SHEEP AND SHEPHERDING. 



it is often a difficult matter to decide what is best to be done. If 

 flukey sheep are to be kept, they may be given salt and iron and 

 gentian and be caked in the hope that good nourishment and tonics 

 will keep them from going back in condition until the ewes have 

 yeaned and the next year's plans can be laid. The position of the 

 parasites in the liver places them beyond all reach of destruction 

 by drugs or any direct destroyers. With good feeding and con- 

 stitutional vigour, a moderate number of flukes will be tolerated. 

 Ditches, where snails haunt, should be thrown, and lime covered 

 over the heaps, and pastures salted and dressed with soot. (See 

 Inflammation of the Abomasum, also Husk or Verminous Bron- 

 chitis.) Such dressing of the land has been found to pay well, 

 because many other kinds of parasites are also destroyed.
