BOVINE TUBERCULOSIS.

have seen some shocking- examples of unthrifty dairy stock 
caused by unsanitary conditions. I discovered a whole herd 
of cows, not long since, where the animals stood two or three 
feet higher behind than in front, through the accumulations 
of their own dung throughout the entire winter of ’93-04 • 
and when I asked the farmer what advantage he thought he 
gained from such a state of affairs, he told me that he could 
milk them easier when they were propped up behind.” 
Further, with regard to the importance of the matter 
Prof. Ernst remarked: “This table of Dr. Parker’s, it seems 
to me, is a very striking one, and a serious arraignment of 
somebody. I do not know that the care of the cattle from 
which a milk supply is obtained is under any one head, but if 
it is not, such a condition of things as this certainly appears 
to me to need attention. In regard to the hygienic surround- 
mgs ol cattle and the specific action of sunlight upon bacilli 
there is no question, of course, that these are very active fac¬ 
tors in the destruction of the vitality of the organism. As to 
the exact time, I think it is hardly possible to state what that 
would be, but it is a well established law that sunlight is the 
best germicide that we have yet discovered.” 
While Dr. Abbott, Chairman of the State Board of Health, 
said: “ Such tables as we see on the chart upon the wall, it 
seems to me, are unusually valuable, and I wish that these 
twelve observations could be increased to several thousands 
in the State. It ought to be. It would be very convincing 
upon this subject to have a large number of tables prepared 
showing what are the actual conditions in which animals are 
kept for the production of milk and for slaughter. There is 
one column I should like to see added to that, and that is, the 
disposal of the dust from the stable and barn. That is one of 
the very important points. It has been shown by observation 
that dust and the disposal of dust has a great deal to do with 
the spread of consumption. Those industries which produce 
very large quantities of dust are those in which consumptives 
are most frequently found, and I wish that that one point 
might be shown, that is, as to the amount of dust and the 
dusty condition of the stable, how it is disposed of, whether
