1 STORRS AGRICULTURAL EXPERIMENT STATION. 
The agitation over the tuberculosis question is upon a 
rather different footing in Europe from what it is in the United 
States. In this country the agitation very largely interests the 
people. In Europe the interest is thus far chiefly confined to 
the scientist. Our agricultural communities are, as a rule, 
better informed upon matters relating to agriculture than those 
of Europe. The large amount of scientific literature which is 
being put into the hands of our farmers by our agricultural 
journals and government publications make our farmers much 
better informed than the farmers of European countries. 
Hence it is that while in this country the farmer feels that he 
is especially interested in the tuberculosis problem, and that - 
this is a subject that he must help settle, the farmer in Europe, 
as a rule, takes less interest in the matter, and looks upon it 
as something that the government must settle for him. The 
European scientists, therefore, who have studied into the mat- 
ter are, as a rule, more interested in it than our own, while 
the public at large knows and cares less of the matter. Scien- 
tific men are leaders in legislation in Europe to a greater ex- 
tent than they are in the United States, and, as a result, less 
mistakes have been made in legislation in Europe than in this 
country. 
The subject before us will be considered under three heads: 
I. The present condition of tuberculosis among cattle. II. 
The battle waged against tuberculosis on the part of the agri- 
culturist. III. Practical conclusions. 
I. THE PRESENT CONDITION OF TUBERCULOSIS AMONG 
CATTLE. 
Ao CAUSE: 
The cause of tuberculosis is to-day very well known, 
and so widely distributed is the knowledge with regard to it 
that little need be said upon the subject. The tuberculosis 
bacillus was discovered about fifteen years ago by Prof. Koch, 
and all of the investigations that have been carried on since 
that time have only served to confirm the conclusion that 
tuberculosis is in all cases produced by this particular bacillus. 
This tuberculosis bacillus is a small plant, which has the power 
to live as a parasite in the bodies of a number of mammals. 
If it finds entrance into the body it can feed itself upon the 
tissues of the animal, it can grow and multiply and continue 
to live under these conditions for a long time. As a result of 
its growth it produces certain chemical bodies which are very
