cious breeding along with poor sanitary conditions, poor ven¬ 
tilation, poor light and bad drainage ; what more do we want 
what more could we have, even if we w r anted to propagate 
the disease instead of control it ? 
Prevention .— In considering the measures to be adopted by 
the authorities for the purpose of controlling the spread of 
tu berculosis, we must not forget that the disease is not confined 
to one species of animals, but it may be communicated to and 
by all kinds of animals, and so long as there remains one tu¬ 
berculous individual (whether man or animal), there will be 
danger to all other animals. 
But while it is not possible to eradicate it by the process of 
killing off diseased animals, it is possible to control it to a 
great extent by improving the surroundings and the sanitary 
and hygienic conditions of the cattle, and by changing the 
present method of breeding and feeding to one more in ac¬ 
cordance with the dictates of common sense. 
In the first place the present provision of the state law 
ought to be enforced ; a competent veterinary surgeon should 
be appointed as inspector in every city and town of the com¬ 
monwealth ; every dairy should be licensed and periodically 
inspected (say monthly or bimonthly), each cow ought to be 
registered and carefully examined for any trace of disease, an 
especial examination being made of the udders; and no cow 
ought to be used for dairy purposes unless it is in a generally 
healthy condition 
And further, as suggested by Prof. Walley, “ Whenever such 
disease is detected, power should be given to the inspector to 
remove the infected animal to a sanitarium or other place for 
further observation, or to an abattoir for slaughter; if in the 
latter case it were ultimately found on autopsy that no disease 
existed of a nature likely to render the meat or milk harmful, 
compensation should be given to the owner of the cow.” 
The barns also ought to be periodically inspected for their 
sanitary condition, which would mclude the cubic space for 
each animal, ventilation, drainage, light, cleanliness, w^ater 
supply, etc. 
In this connection I would call your attention to the grant-
