value; it may not be administered in the proper

One of the most commonly used drenches is 

 turpentine, but more satisfactory results are 

 obtained from the use of coal-tar creosote, or 

 coal-tar creosote and thymol, or gasoline, or 

 bluestone. 



COAL-TAB CEEOSOTE. 



I have had excellent success in treating 

 sheep, goats, and cattle for the twisted wire- 

 worm (Strongylus contortus) with a 1 per cent 

 solution of coal-tar creosote. The medicine is 

 easily prepared and quite inexpensive. It may 

 be purchased of the druggist in small quantities 

 of 1 ounce, or in pound bottles. One ounce is 

 sufficient for about 20 adult sheep, and the cost 

 of the treatment is less than one-half a cent per 

 head ; if creosote is purchased by the pound, the 

 cost is reduced to less than one-quarter of a 

 cent per head. If creosote is called for at a 

 drug store, beechwood creosote will usually be 

 dispensed. This is more expensive than the 

 coal-tar creosote and not so satisfactory in ex- 

 pelling worms. 



A 1 per cent solution of coal-tar creosote is 

 made as follows: 



Coal-tar creosote 1 ounce. 



Water 99 ounces 



(99 ounces — 6 pints and 3 ounces.) 



Twisted wireworms (Strongylus contortus) 

 taken directly from the stomach of sheep or 

 cattle die in one-half to one and a half minutes 

 when immersed in this solution.
