disease in a dairy through the presence of one tuberculous animal 

 could not be wanted. 



It is hard to understand why, after the large amount of work 

 w^hich has been done and the effort which has been made on the 

 part of the officials of this division to educate the dairymen, giv- 

 ing tliem the best and latest information on the subject and ad- 

 vising them as to the most economical methods to follow in eradi- 

 cating the disease, such a condition should exist. In this in- 

 stance the experience has been a costly one, and one calculated 

 to allay all further opposition to the carrying out of methods of 

 complete eradication of the disease. I am glad to report that in- 

 stances of this kind are rare and that opposition to the carrying 

 on of the work of the eradication of bovine tuberculosis has died 

 down and in its stead has sprung up a keen desire on the part of 

 dairymen to offer every help possible. 



This year's general test of the dairy herds of the island of 

 Oahu is nearing completion and the results are gratifying, indeed. 

 Up to the present time figures show the following: 



Total Number Total Number Total Number 



Tested. Passed. Condemned. 



4,379 4,586 153 



From the above figures it will be seen that the percentage of 

 tuberculous animals up to the present time is 3.22%. There re- 

 mains in the neighborhood of fifteen hundred animals still 1o l>e 

 subjected to the test, but as these are owned by the O. R. & L. 

 Co., and as the percentage of diseased animals among then" stock 

 is very low, indeed, being less than 1%. the addition of these to 

 the total number will lower the final percentage of tuberculous 

 animals. 



That the campaign against bovine tuberculosis is meeting with 

 success is evidenced by the marked decrease in the percentage of 

 tuberculous animals among the dairy herds of the city and county 

 since the beginning of the work in 1909. This is brought out 

 clearly in the following figures : 



Per- 

 T. Tested. T. Passed. T. Cond. centage. 



First Test 1,916 1.475 441 23.01% 



Second Test 4,152 3,930 222 5.34% 



Third Test (uncom- 

 pleted) . 4,739 4,586 153 3.22% 



In the three years which this work has been going on the per- 

 centage has been brought from one quite large, 23.01%, to one 

 quite small, 3.22%, and which may be smaller yet when the test is 

 completed. This is making rapid strides toward the time when 

 bovine tuberculosis among dairy stock on the island of Oahu will 

 be a thing of the past and when this, the third general test, is 

 finished we will have advanced a long way toward the eradication
