 conditions leading to sickness in his flock to be able to satisfac- 

 torily diagnose and differentiate disease, and in cases where his 

 intelligence appears to him to be at fault before the majority of

 anthrax is the disease affecting the flock. As in almost all cases

 to an entirely new locality and vaccinating the healthy members 

 with Pasteur's Anthrax Vaccine.

In all cases of anthrax is only preventive, the disease run-

 with any hope of success. The matter of first importance is to 

 find out whether the complaint causing destruction to the flock 

 is anthrax or not. Should it be this disease, the sheep should 

 immediately be moved to different pastures or ranges, and Pas-

 the flock. This consists in the injection under the skin of the 

 hind leg of an attenuated virus of the disease, which has to be 

 specially prepared, and is obtained from the Pasteur laboratory 

 in Paris, France, agencies for which exist all over the civilized 

 world. Sheep when once treated with the anthrax virus are 

 immune to the disease for the balance of their lives. This pro-

 introduced in America with good results. 



In Europe thousands of cattle as well as sheep are sub-
