while the latter installed the most modern electric milk purifying 

 devices, and what is most important, refused to receive milk ex- 

 cept from clean herds and sanitary premises. xA.t the same time 

 the local Board of Health, through its Pure Food Commissioner, 

 cooperated by enforcing the requirements of the statutes per- 

 taining to the official milk standards, with the result that the City 

 of Honolulu may be said to have a milk supply second to none 

 and eqijal to the best of any city of its size in the United States. 



The adoption of the intradernial method of tuberculin testing 

 has, so to speak, revolutionized the campaign of eradication of 

 bovine tuberculosis, compelling, as it does, the confidence of the 

 owners, and at the same time obviating the many inconveniences 

 and objectionable features of the old subcutaneous method. The 

 fact that an owner can see for himself wdiether an animal reacts 

 or not, that he no longer has to blindly accept the word of the in- 

 spector — frequently in doubt himself as to whether the tempera- 

 ture record spells positive or negative — has by one stroke done 

 away with ninety per cent, of the old objections to having the 

 animal tested, and when a majority of the consumers demand of 

 the producer to know whether the cows have been treated and 

 whether any of the reactors are left on the premises before leav- 

 ing an order for milk to be delivered at his home, then the moral 

 effect becomes binding, and the result comes very close to one 

 hundred per cent, of "clean" dairies, as is now the case in Hono- 

 lulu. It is the aim of this division to extend the work of eradica- 

 tion of bovine tuberculosis to the entire group, and if the same 

 spirit is found to prevail on the other Islands as on Oahu, the 

 end is in view. With the assistance of the Deputy Territorial 

 Veterinarians on the other islands, who must be remunerated for 

 the time given to the w(M-k, and with the necessary funds for 

 traveling expenses for an insi^ector and an assistant sent out from 

 this office, with an automobile, it is antici])ated that a sufficient 

 number of milk producers will be f(nuid willing to have their 

 herds cleaned up, to compel tlie l)alance to eitlier follow suit or go 

 out of the business. 



The only disease wliich has at all caused any alarm during the 

 past year is cerebri) sf'iiuil incuiiii:;ilis among horses and nuiles. 

 Outbreaks of this have occurred on all four of the principal 

 islands, but es])ecially on Maui. In accordance with the latest 

 views on the subject the disease must be classified as a toxaemia, 

 due to the assimilation of nnisly or mouldy \cv^\. rallicr tli.m as 

 an infectious disease. The condition cannot be transmitted trom 

 animal to an'imal, even b\' direct inoculation, and cm always be 

 controlled when it is ])ossible to locate the existing cmse, which 

 is generally foimd to be musty grain or possibly water found to be 

 contaminated bv decomposing vegetable matter. .\ rather severe 

 outbreak of this di.sease was investigated during the j^ast year, 

 and an attcmj)t to stop it was made by applying Pasteiu' filters 

 to the water pipes supplying the stables where the affected ani-
