been tested some years ago, and the diseased animals allowed to remain, 

 were retested. In some of these herds 50 per cent of the animals were 

 diseased and still a large number suspicious, many of which reacted on 

 subsequent tests. 



The work done in 1911, when we tested practically twice as many 

 cattle as in 1910, and four times as many as in 1909, the percentage of 

 reaction was reduced to 1.4 per cent. With this large increase tested, the 

 percentage of reactors fell to within 1.05 per cent of our first year's test- 

 ing. 



Our work indicates that less than one-tenth per cent of our native 

 cattle are tubercular. The cause of so small a per cent of the disease in 

 our native cattle may be explained by the mild climate and the cattle 

 being kept in barns only a short time during our very short, mild win- 

 ters. Cattle rarely go to winter quarters before Christmas. April fre- 

 quently finds them on pastures again. During the winter when they are 

 in stables it is usually simply for milking or during falling weather and 

 an occasional cold day. The remainder of the time they are in spacious 

 yards, or possibly in the stalk fields or meadows. 



In these herds where the large amount of disease was found the reac- 

 tors have been slaughtered and the barns and yards thoroughly disin- 

 fected and subsequent tests revealed no reactors. We now feel that dairy- 

 men and beef breeders can safely locate anywhere in the State with prac- 

 tically no fear of their cattle contracting the disease.
