THE DISEASES OF SHEEP. 299 



reputation as a vermifuge. I have used it in 

 a number of cases and have found the claims 

 made for it to be more or less justified. Three 

 objections, however, arise to its use, and I can 

 not, therefore, consider it an ideal treatment. 

 These objections are: 



(1) Not less than three doses, and usually 

 four to six, are required to expel the worms. 

 This involves a great exj)enditure of labor, and 

 it is therefore imyjracticable on the large 

 ranches. 



(2) While several doses are not necessarily 

 injurious to the stock, still, if the doses are 

 large, repeated drenches cause a more or less 

 severe congestion of the' bowels. Not only that, 

 but repeated handling of range sheep, with the 

 necessary preliminary treatment of withhold- 

 ing food, is injurious to the animals. 



(3) If used on animals suffering from 

 pleurisy, it is likely to be fatal. I have had 

 several fatal cases of this kind. 



Nearly all vemiifuges are, however, more or 

 less poi.sonous in one way or another, and gaso- 

 line, if properly used, is not particularly dan- 

 gerous. The necessity of repeating the dose 

 from four to nine times in order to effect a 

 complete cure will, however, militate against 

 its general adoption. 



If gasoline is used, ammonia also should al- 

 ways be kept on hand. If an animal is sud- 

 denly overcome by the effects of gasoline, a 

 small amount (a teaspoonful or so) of aromatic 

 spirits of ammonia may be given in water as a
