comimitted to a single-method policy, this Division is, nevertheless, 
opposed to the introduction of an nnattenuated, highly virulent virus in 
the control of any infectious and contagious disease of live stock. 
Such introduction and use has never yet, wherever tried, accomplished 
the eradication of any disease. 
As far as hog cholera virus is concerned, its introduction into this 
Territory is not warranted in view of the fact that the filtrable virus 
disease of swine, i. e., hog cholera, has never definitely been proven to 
exist here. Furthermore its introduction at the present time and under 
the present circumstances — absolute lack of control of the sanitary con- 
ditions connected with the swine industry and absolute inability to 
control the spread of the virus, with the means at our disposal, renders 
such introduction extremely dangerous and inadvisable, to say the least. 
Strict sanitation, combined with the use of a potent serum, will elim- 
inate the danger of hog cholera, and is all that is necessary to control 
the disease and is, moreover, an entirely safe method and will lead to 
final complete eradication, the goal which should always be kept in 
mind. 
In the control of infectious and contagious diseases there are two out- 
standing principles which must be strictly observed, namely: 
1. Eliminate the spread of the infection and you have controlled the 
disease. 
2. Eliminate the source of the infection and you have eradicated the 
disease. 
Needless to state, if the outbreak is confined to the original center of 
infection the loss from such outbreak is kept at a minimum and the 
source of the infection is more easily and completely eliminated and 
those agencies which are known to be responsible for the spread of the 
infection are rendered harmless. It should also be self evident that you 
cannot eliminate the infection if you are going to import it by the 
quart in the most virulent form possible. 
EAST HAWAII 
Dr. Elliot reports as follows: 
Tuberculosis Control — During the past month a total of 193 head of 
cattle were tested, of which number 191 passed and two were condemned 
and branded. 
Bovine Hemorrhagic Septicemia — The outbreak of this disease on the 
Kaalualu Eanch has been kept to one paddock. During the past month 
eight deaths occurred, and a total of 1,805 head of cattle were vac- 
cinated. 
WEST HAWAII 
Dr. Rowat reports as follows: 
Tuberculosis Control — ^The work in this field was confined to procur- 
ing signatures to indemnification vouchers and making autopsies on 
condemned cattle. 
Bovine Hemorrhagic Septicemia — -Several scattered outbreaks of this 
disease occurred on the Parker Ranch, but owing to prompt measures 
being taken to confine the disease to the original centers of infection 
and the vaccination of all exposed cattle, the loss was kept at a mini- 
mum, there being but twelve deaths prior to vaccination and three 
deaths subsequent thereto. A total of 4,177 animals were vaccinated. 
This speaks very highly for the protection afforded by means of such 
vaccination. 
Glanders — Several inspections were made during the month at the 
Puakea Plantation Company's stables, where cases of glanders had been 
found before, with the result that one acute case of glanders was found
