pecuniary loss, in which some of the Western States have 

 been involved. But efforts for the eradication are now being 

 made there, with good prospect of success. Several sus- 

 pected cases of this disease were found in Essex County by 

 the veterinary member of our Board, which were examined 

 and placed under surveillance ; but the lesions, though 

 somewhat similar, did not develop in typical form, and the 

 watch was withdrawn. To this date it is believed that not a 

 case of the kind has occurred in this State ; but our com- 

 merce in horses with all parts of the country is so unre- 

 stricted that horse breeders need be cautious in selecting 

 both sires and dams which in this respect are in perfect 

 health. 



Swine. 



There has been less disease among our swine the present 

 year than in previous years of recent date, or else our local 

 officials have been less faithful in reporting their cases. 

 There have doubtless been cases of hog cholera, derived 

 from the usual source of swill containing the germ of the 

 disease from Western cholera pork ; but the tendency on the 

 part of swine owners has been to give that name to every 

 disease to which this class of our animals are subject. The 

 regulations made by the Board to prevent the spread of this 

 disease were given in full in our last animal report. They 

 have been kept in force until the present time ; and we are 

 satisfied that the prevalence of the disease has not been 

 increased by their enforcement, that substantial justice has 

 been received by our swine owners, and the State saved 

 from much expense which could not be made effective to 

 decrease or exterminate the malady.
