THE PREVENTION OF TUBERCULOSIS. 311 
mals were fed. There were no special provisions for venti- 
atmg, and the floor being of wood, and old, could not'be 
kept more than moderately clean. And yet this herd, al¬ 
though it had been exposed to contagion, was by the tuber¬ 
culin test found to be healthy. The history of it is both 
interesting and instructive. The fourteen animals kept in 
this stable had been owned on the place for several years 
All of the summer and fall of 1894 they went in the same 
pasture and in the same yards with six other cows which 
were brought from the State of New York. It was subse¬ 
quently found that the herd from which the six cows came 
was a perfect hotbed of tuberculosis. Consequently, in Jan¬ 
uary of this year, Mr. Sloane had the entire herd tested with 
full doses of tuberculin. Every one of the six new cows re¬ 
acted, but not one of the original fourteen. On slaughter, 
five of these six cows were found extensively diseased, two 
of them being extremely bad. One of these two worst cases 
was a cow which had been exhibited and had taken a first 
premium at the World’s Fair, and must have been far gone 
with the disease at the time of her exhibition. 
This feature of having individual stalls for individual ani¬ 
mals ought in the construction of a stable to take precedence 
over every other consideration. While the plan I have sug¬ 
gested is open to criticism on the ground of not being com¬ 
plete enough, yet it is probably as complete as is practicable, 
is an immense improvement over any other system in general 
use, and has to recommend it the fact that it can be applied 
to any of the stables at present in existence, and that at a 
comparatively trifling cost. 
In regard to the matters of cubic space, ventilation, light 
and drainage, there seems to be among stock-owners no clear 
conception of what is fit and necessary. The whole matter 
seems to be in a state of fog and chaos, and the good feat¬ 
ures which are occasionally met with seem to be more the 
result of chance and whim than of well directed and intelli¬ 
gent plan.
