SWINE DISEASES. 
Considerable time has been spent in vaccinating hogs in the Koko 
Head, Kuliouou and Niu districts, with varying degrees of success. A 
number of reports from the Board of Health have been investigated 
but no sick pigs were found and no history of the disease could be 
learned. 
In the various outbreaks which have occurred in different sections of 
the island of Oahu, vaccination has not shown the results which might 
have been expected. In some herds vaccination has accomplished mar- 
velous results, stopping the losses immediately, and in other herds no 
apparent benefits have been experienced. 
After considerable study of the disease, as it is occurring in these 
outbreaks, and the poor results obtained in many instances through 
the present methods of vaccination, the conclusion has been reached 
that this disease, hemorrhagic septicemia or swine plague, should be 
handled in the same manner as anthrax, i.e. an attempt to establish 
a certain degree of immunity through the means of a serum-simultaneous 
method of vaccination. 
Working upon this theory, I have taken up the subject of the pro- 
duction of a special virus and serum with one of the foremost biological 
laboratories on the mainland. If they will be willing to manufacture 
such a product under my direction I will conduct a series of experiments 
to prove whether or not an immunity can be produced, the approximate 
degree of such an immunity and the length of time it will last. 
With such a product we can then tackle the problem from a dif- 
ferent angle. Instead of waiting for outbreaks to occur and then 
treating the herds we can attempt to immunize the herd and by so 
doing prevent the occurrance of the disease. 
In the light of present knowledge this seems to be the logical way 
to prevent these recurring losses to both, the cattle and swine in- 
dustries. 
QUAEANTINE STATION. 
Considerable change and improvement in the general aspect of the 
Quarantine Station have taken place during the past month in that 
the ramshackle buildings which constituted the keeper 's cottage were 
removed, the site of said buildings cleaned up and a new cottage built 
for the keeper and his family. 
The new building, while highly unsatisfactory from the point of view 
of a finished job, is nevertheless a vast improvement over the former 
living quarters. The cess-pool should be condemned both as to position 
and workmanship. Already it has caved in. It is full of w^ater prac- 
tically all the time and this without ever having been in use. Provision 
should be made to pump it out frequently or else the odor from it, es- 
pecially during the summer months, will be far from pleasant. 
LIVE STOCK IMPORTATIONS. 
Seven head of purebred holstein cattle, imported by C. Brewer & Co., 
constituted the only shipment of note during the month. 
WEST HAWAII. 
Dr. Eowat reports that the chicken cholera situation has greatly im- 
proved, no new cases having occurred in some time. 
During the month two outbreaks of hemorrhagic septicemia occurred 
on the Parker Ranch. One animal died in the first outbreak and two in
