Only one other dog, a valuable Boston bull terrier, died from 

 heart failure. This animal had been in excellent health up to a 

 few minutes before death. The keeper of the station was at the 

 time distributing the evening meal and all the dogs were, as usual, 

 more or less excited. The dog in question was also dancing 

 around and barking when suddenly it rolled over, frothing at the 

 mouth, and was dead in a few minutes. A post-mortem exami- 

 nation showed valvular insufficiency in both sides of the heart, so 

 the dog could, at the very best, have lived but a short time. This 

 condition is very common among well bred dogs, some authorities 

 placing it as high as five per cent in all well bred dogs of the pet 

 or toy varieties, the symptoms, especially when death does not 

 occur quite so sudden, frequently being mistaken for rabies in 

 countries where the disease occurs. This is the third case ob- 

 served at this station, the two former ones happening imme- 

 diately after the victims had been visited by their respective 

 owners, for which reason such visits are discouraged as much 

 as possible. 



Bovine Tuberculosis Control Work. 



As shown by the appended report of the Assistant Territorial 

 Veterinarian, a recent test of the Waialae Ranch dairy herd 

 shows a relapse which would be highly discouraging were it not 

 for the fact that the probable cause of the same may be elimi- 

 nated. The previous test of this same herd showed a reduction 

 in the number of tuberculous reactors to nearly one-half of one 

 per cent and great hopes were entertained that the disease was 

 now near complete eradication. It will be remembered that this 

 herd, the largest dairy herd in the county, showed an original 

 infection in the neighborhood of 70 per cent. The owner has 

 labored assiduously at the suppression of the disease and has 

 assisted this Division in every way to this end. But nevertheless 

 the repeated recrudescence of the disease every time when it was 

 practically eradicated, finally led to the conclusion that extraneous 

 infection might, to some extent at least, be the cause thereof and 

 inquiries led to the discovery that a neighboring herd of beef 

 cattle seems to be more or less infected with tuberculosis. 

 Whether beef cattle, or in other words, cattle from which no milk 

 is sold or used for human consumption, under the regulations 

 now in force here, can be dealt with as a center of infection, 

 pure and simple, is a question which must be decided before 

 action can be taken. The fact that bovine tuberculosis, until 

 quite recently, has not been considered or dealt with as a dan- 

 gerously infectious disease — except when milk from tuberculous 

 cows was concerned — would make a legal decision of the ques- 

 tion of the local authorities' right to interfere, without the own- 

 er's consent, of doubtful value. It has therefore been found
