the one county of the state, will be an excellent example of what 

 can be done, and will, if successful, lead to a statewide campaign 

 with the same object in view. 



Use of Hog-cholera Remedies. — As a means of preventing hog- 

 cholera a large number of patent medicines are on the market, many 

 of which claim to be capable of preventing the disease. Most of 

 these compounds are absolutely worthless. A considerable num- 

 ber of them do possess some value, in that they contain certain 

 medicinal agents which remove intestinal parasites from the 

 animal and at the same time improve digestion and act as a gen- 

 eral tonic. As far as containing any special drug which acts as a 

 direct prevention to the development of cholera, there is no such 

 remedy as yet discovered. 



Of all the drugs which have been experimented with in the 

 prevention of hog-cholera, there are two which probably are more 

 effective in this direction than any other remedies. These two 

 agents are hyposulphite of sodium and black antimony. Officials 

 of the Dominion Government, with whom I associated while in the 

 Province of Ontario, were quite firm in the opinion that they had 

 seen some very excellent results from the use of these two drugs, 

 both as a preventive and in a curative manner. It is not very 

 Ukely that these agents, either singly or in combination, possess 

 any great power as curative remedies for this disease, but that they 

 do possess great power for good, in that they tend to regulate the 

 condition of the bowels and maintain a good digestive action, can- 

 not be denied. 



Several years ago the following formula was devised by Dr. 

 D. E. Salmon, of the United States Bureau of Animal Industry, 

 and has since been quite extensively used: 



Wood charcoal 1 pound. 



Sulphur 1 " 



Sodium chlorid 2 pounds. 



Sodium bicarbonate 2 



Sodium hyposulphite 2 



Sodium sulphate 1 pound. 



Antimony sulphid 1 



This is all mixed together in the form of a powder, and should 

 be given to hogs in the dose of a tablespoonful to each 200 pounds
