metal cans, colored labels and other injurious ingredients. Then 

 the swill is placed in the clean heating tanks with the requisite 

 amount of chopped green stuff and whatever other feed may be 

 raised on the place for the animals. To this should be added a 

 small amount of salt, charcoal, sulphur, antimony, etc., ae rec- 

 ommended as a preventive for hog cholera by the federal Bureau 

 of Animal Industry, as follows : 



Wood charcoal 1 lb. 



Sulphur 1 lb. 



Sodium chloride (salt) 2 lb. 



Sodium bicrbonate 2 lb. 



Sodium hyposulphite 2 lb. 



Sodium sulphate 1 lb. 



Antimony sulphid or black antimony 1 lb. 



These ingredients should be powdered by passing through a 

 coffee mill or in a large mortar, thoroughly mixed, and of the 

 mixture a heaping tablespoonful should be added to the feed for 

 every 200 pounds of hog in each pen. This prescription is re- 

 peated here because good results have been seen wherever it has 

 been used, provided all the other precautions have been taken. 

 But the medicine alone will not do it. 



The fact remains, however, that hog cholera still exists on this 

 island, and, even though there is not much of it or else that the 

 hogs here have nearly all become immune, it cannot be advised 

 to remove the restrictions against the shipping of hogs from this 

 island to the others, for some time to come. Nor is there suffi- 

 cient hog cholera to warrant the recommendation of serum im- 

 .munization on a large scale so long as the price of serum remains 

 anywhere as high as at present. 



That the vigilance against the further introduction of virulent 

 hog cholera from the Coast is still being guarded against will be 

 seen from the appended letter from the federal live stock in- 

 spector in San l^Vancisco, and which is self-explanatory. The 

 fact should always be borne in mind that the virulence of the hog 

 cholera microbe, like that of many other infectious and conta- 

 gious diseases, varies so greatly in different localities that even if 

 ap])earances justify the conclusion that a large percentage of the 

 hogs here are immune to the infection as if exists here, there is 

 no telling what degree of virulence they would be able to resist 

 should a .severe strain of infection accidentally be introduced. It 

 is therefore reassuring to see the care with which our regulations 

 are being enforced by the federal ins])ect()rs on the Coast, as tes- 

 tified to by Dr. Hicks' letter. 



During the past montii a hitlu-rto unobserved and seemingly
