were a matter of law instead of volition the farmer would fail 
to give it personal supervision, and the experiment would fail 
in such a large majority of cases as to bring the whole plan 
into disrepute. It will only succeed where the farmer will take 
a personal interest in the carrying out of the scheme. It is 
hoped, however, after a few years had demonstrated by ex- 
amples in numerous localities the feasibility of the plan, that 
legislation looking in this direction might be feasible. At the 
outset it would be futile. It is, however, a general belief that 
the expenses connected with preparing the tuberculin for the 
inoculation of the animals should be free to the farmer. This is: 
advisable for two reasons. In the first place, it will make the 
farmer much more inclined to adopt the scheme than if the 
original inoculation were a matter of expense to him; and, 
secondly, it insures that the tuberculin and the methods of in- 
oculation used are satisfactory inasmuch ‘as they will be under 
official inspection. Already two or three of the European 
countries have advanced as far as this, giving the free use of 
tuberculin to such farmers as are willing to adopt the methods 
suggested along the lines indicated above. 
One of the most important phases of the adoption of this 
method of Prof. Bang is that the young animals should be in- 
oculated. This is of so much importance that it deserves to be 
considered by itself and should be recommended entirely apart 
from the general adoption of the method of Prof. Bang. The 
testing of young cattle by tuberculin will detect at once the 
animals which have already yielded to tuberculosis. These 
animals, above all others, should be excluded from the herd. 
If they have taken the disease in the earlier period of their life, 
it is practically certain that the disease will advance in them 
rapidly. They will not only be of no use to the herd in the 
future, but will become a menace to the rest of the animals. 
Even if they should recover from this attack, the fact that they 
have yielded to the disease early in life shows that they have 
weak resisting power. On the other hand a slaughter of such 
young animals is not a matter of such serious expense as it is 
later. The flesh can be sold with proper precaution, and the 
animals have not yet become valuable as dairy animals. It is, 
therefore, above all things desirable, if a farmer desires to free 
himself from this great burden, that all calves should be tested 
with tuberculin, and no calf should ever be allowed to join the 
healthy herd until it has proved by failure to respond to this 
test that it is free from every taint of this disease.
