niiist be prepared for each individual outbreak, or. in other words, 

 that a severe outbreak yielding a good deal of material (scabs) 

 cannot be taken advantage of for the protective inoculation of 

 other flocks, nor for the treatment of birds of a different class or 

 variety. It has been learned during the present month that car- 

 bolic acid may be added to the vaccine as a preservative without 

 injury to the treated birds, but whether the effectiveness of the 

 vaccine is diminished by this addition of carbolic acid, it would 

 seem almost impossible to ascertain. As now prepared, the vac- 

 cine deteriorates rapidly through putrefaction, unless kept di- 

 rectly on ice. But even though this treatment of vaccination 

 may seem to have several objectionable features connected with 

 it, the results have, nevertheless, been so satisfactory in most 

 cases as to warrant its use wherever poultry is raised and when 

 the disease makes its appearance. 



I would, therefore, recommend that the circular of instructions 

 herewith appended be reprinted in 250 copies and that the same 

 be distributed among the poultry raisers of the Islands. 



HOG CHOLERA. 



No outbreak of this disease has occurred during the past 

 month. The anti-hog cholera serum, of which the Board keeps 

 a supply on hand against sudden outbreaks, can now be obtained 

 for 1.5 cents per c.c, or perhaps a little less. 



BOVINE TUBERCULOSIS CONTROL WORK. 



The 1916 test has now been started, and will be carried through 

 as soon as possible, as it is intended to test all dairy herds twice 

 this year. A considerable number of pure-bred Holstein cattle 

 have arrived here recently, and although the unfavorable weather 

 of the past two months caused a decided fall in the milk produc- 

 tion, it may now be said to have returned to the normal. The 

 muddy condition of most paddocks caused several complaints 

 about dirt in the milk, and it is hoped that the milk producers 

 will take the same to heart, as any kind of sediment in a bottle of 

 milk is inexcusable, and may l^e the cause of much sickness 

 among the children of the community. 



LIVE STOCK FROM NEW ZEALAND. 



Two importations of Merino rams, each consisting of 25 head, 

 arrived here during the month. They were exceptionally fine 

 animals and will no doubt put their stamp on the flocks of the 

 Parker Ranch, for which place they were imported. 



Respectfully submitted,
