room. Water supply should be abundant, pure and obtained 
from deep wells when possible. No unwholesome, spoiled or 
putrifying food or any material likely to impart unpleasent 
taste or odor should be used. Animals should have access to 
shelter at all times and should be cleansed once daily ; must 
have kind treatment and the milk from excited cows should not 
be used. Milking should take place in a clean, well-ventilated 
building and the milk then properly attended to. The dairy 
schools are a good step in the right direction for the production 
of sanitary milk. The consideration of pure milk and the ad¬ 
vantage in obtaining it seems to fall naturally to veterinarians; 
they should do all in their power to restore the confidence of 
the consumer, thus increasing the consumption of milk. The 
importance of this work is better appreciated when we realize 
# that there are about 17,000,000 cows in this country ; it is es¬ 
timated that 5,000,000, of them, whose annual product is valued 
at $150,000,000 produce milk for direct consumption. 
Dr. Leonard Pearson in his paper on the work of Prof. Bang 
quoted him as one of the greatest authorities on tuberculosis of 
cattle ; and gave to him the credit of having first discovered and 
called attention to many of the facts in connection with this 
disease that were previously unknown. Prof. Bang’s country is 
one of the smallest in Europe, but its inhabitants are a thrifty, 
frugal, and conservative people, of a high order of intelligence ; 
they depend largely upon the dairy for their support, and al¬ 
though the country has a population of but 2,200,000 and an 
area of little over 15,000 square miles, about one-third that of 
Pennsylvania, there are in Denmark about 1,700,000 cattle (ap¬ 
proximately the number in Pennsylvania). In 1890 Denmark 
exported more than $22,000,000 of butter and more than $2,- 
000,000 worth of cattle; this amounts to more than $10 for 
each inhabitant of the country. The subject of .tuberculosis is 
of national importance in Denmark, as it involves the principal 
source of the country’s wealth and prosperity. Prof. Bang is 
at the head of the work there now, and has at his command an 
appropriation of $30,000 per annum. By the use of tuberculin 
it was found in testing 53,000 cattle that 38.5 per cent, were 
tubercular to greater or less degree. Long continued contact is 
a means of spreading the disease, while short exposure is not al¬ 
ways necessarily dangerous. Skim-milk from creameries may 
become a potent factor in the spread of the disease, part of the 
whole milk being supplied by tubercular cows, the mixed pro¬ 
duct is returned to the farm and disease communicated to healthy
