tion of the disease, its nature, cause, manner of transmission and 
economic importance, told in language comprehensive to the 
veriest tyro and with a total absence of scientific or technical 
terms. This primer would lend itself well to translation into the 
various languages of the heterogeneous dairy industry of these 
Islands and, when copies are ultimately received, I shall strongly 
recommend its translation into at least the Hawaiian, the Portu- 
guese and one of the Oriental languages, and the wide dissemina- 
tion of copies thereof among all dairy owners and laborers as 
well as milk dealers and all others in any way connected with the 
cattle industry, whether for daily or beef purposes. 
The intradermal test with which we have obtained such fine 
results here was hardly more than mentioned though some work 
had been done in an experimental way with it at the Experiment 
Station of the Bureau of Animal Industry, near Washington, D. C. 
The number of tests made were, however, absolutely insufficient 
to lead to any definite conclusions and when a few doubtful reac- 
tions were met with, even though admittedly due to faulty tech- 
nique, the method was at once concluded to be less reliable than 
the subcutaneous one, and its great advantages of simplicity and 
cheapness were lost sight of. I did, however, whatever was pos- 
sible to prevent the official relegation of the method to the junk 
heap and succeeded in interesting a number of the leading sani- 
tarians, including the chief of the Bureau of Animal Industry, 
and to obtain their promises of exhaustive experiments with, and 
further investigation of, the method. I was also promised that 
the Bureau will prepare and furnish us with the special tuberculin 
required for the test, free of charge. The work which has been 
performed here with the eradication of bovine tuberculosis was 
highly commended, and its continuation encouraged with the 
promise of every assistance which it is possible for the Federal 
Bureau to lend in the matter. Our rapid strides in regard to the 
improvement of the milk supply and especially the installation 
here of one of the most modern milk purifying plants was quite 
a sensation, it being somewhat out of the usual for the Washing- 
ton and New York heads of bureaus and divisions to get informa- 
tion on dairy sanitation and hygiene from the South Seas. In 
this connection I must mention that I called on the manufacturers 
of the electric milk purifying machinery, while passing through 
New York, in order to ascertain whether the plant installed here 
could possibly be provided with a self-registering and regulating 
appliance, which would make official supervision a matter of 
automatically obtained records, thereby insuring to the consumers 
an absolutely clean and safe product ; and I was agreeably sur- 
prised to find that the company was then working on tliat same 
problem, and that before long a very ingenious device, which will 
insure not alone an absolutely even temperature, but will auto- 
matically regulate the stream of milk passing through the ma- 
chine, in such a manner that each atom of the product will be ex- 
posed to the required temperature at a definite lengtli of time,
