224 DISEASES DUE TO INTERNAL PAHASITES. 



solved in water. Where large numbers of sheep have to be 

 treated pumpkin seeds have been used, and in many cases with 

 satisfactory results. These can be given in unlimited quantities, 

 mixed with dry feed, such as shorts, the great drawback in using 

 this simple remedy being the difficulty to get the sheep to eat a 

 sufficient quantity. After treatment the flock should be mOved 

 to fresh and uninfected pastures. The ground from which they 

 have been moved should not be used to graze sheep on for at 

 least two seasons, and where practicable the pasture should be 

 given a dressing of lime or salt. 



A new method, and apparently, from all data which can be 

 gathered on the subject a most successful one, is the use of

 treatment of this affection. This is used as follows : For lambs

 line in half a pint of linseed tea or oat-meal gruel; repeat daily 

 for three or four days. Adult sheep take from two to three 

 tablespoonfuls. This treatment is simple, and from all accounts-

 the reports from that country were most gratifying, leading to 

 the adoption of this agent by many prominent sheep men in this 

 country, notably Jos. E. Wing of Mechanicsburg, Ohio, who re- 

 ports favorably. 



Nodular Disease of the Intestines. 



This is a diseased condition of the intestines, due to a para- 

 site called the oesophagostoma cokmibianum, the last word 

 signifying that it was first found in the District of Columbia. 

 The investigations leading to and determining this particular 

 species of worm were successfully carried out by Dr. D. E. 

 Salmon, Chief of the Bureau of Animal Industry, assisted by 

 Dr. Cooper Curtice, also a member of the Department of Agri- 

 culture. Its presence can only be detected by post mortem ex-
