TUBERCULOSIS CONTROL 
During the past month a total of 46 head of cattle were tested on the 
various islands, of which number 2 head were condemned and branded. 
Besides the above testing, autopsies were performed on 10 head of 
condemned cattle of which 9 head showed definite lesions of tubercu- 
losis. In one case, a young heifer, no definite lesions of tuberculo.iis 
could be found. 
INFECTIOUS AND CONTAGIOUS DISEASES. 
No reported losses have occurred among the live stock of Oahu. Dr. 
Golding reported the loss of a few hogs in the Mana district of Kauai. 
An investigation into the cause of death did not establish Dr. Glaisver 's 
diagnosis of hog-cholera. The sanitary conditions of the premises were 
a replica of those obtaining in the swine-raising sections of Oahu. To 
say that they w^ere filthy is to put it mildly. In the case of the j)ig 
pens which I went through in Mana, Kauai, I advised total destruction 
by fire, as any other form of disinfection is hopeless and absolutely oat 
of the question. 
When it comes to the question of making a proper and definite diag- 
nosis in these cases, it must be borne in mind that the ditferential diag- 
nosis of hog-cholera from the many other ills of swine, is essentiall}' a 
laboratory procedure and not one of field autopsy. It is a matter of 
recorded fact that the original differential diagnosis of hog-cholera and 
swine plague or hemorrhagic septicemia, was performed in the laboratory 
and with the use of experimental animals. This is a fact which is gen- 
erally lost sight of by the majority of practicing veterinarians. 
Dr. Golding has been fully instructed in the matter of furnishing j;ie 
with the necessary material for diagnostic purposes. 
Occasional losses are still occurring from hemorrhagic septicemia 
among the cattle and horses on Maui. Dr. Fitzgerald reports, however, 
that he con.siders the outbreak has practically run its course. 
No outbreaks of disease have occurred on the island of Hawaii during 
the past month. Dr. Rowat reports that the last death from hemor- 
rhagic septicemia on the Parker Ranch occurred some time in May. 
CONTAGIOUS EPITHELIOMA 
Reports coming in from various sources, on the use of the new vaccine 
for sore-head in poultrj', are uniformly favorable. In some instances 
great enthusiasm is being displayed. The vaccine as now being pre- 
pared is a high count, polyvalent vaccine; a true vaccine, not a bactcrin. 
In certain instances it is apparently conferring a high degree of im- 
munity in very young chickens. If it is finally definitely determined 
that an immunity, even though it be of short duration, is conferred by 
the use of thi.s vaccine, it will mean considerable to the poultry indust.iy 
of the Territory. 
WEST HAWAII 
Dr. Rowat reports as follows: 
TUBERCULOSIS CONTROL:— "For the present month I beg to re- 
port a trip to Kohala on the 7th and 8th, making autopsies on three 
condemned animals, and a second trip on the 10th and 11th making three 
more post-mortems and finishing all of the condemned cattle at the Hawi 
Mill and Plantation Company. 
GLANDERS: — ''During the month I have been to Kohala three times 
and each time investigated the glanders situation without finding any- 
thing to arouse suspicion.
