176 STORRS AGRICULTURAL EXPERIMENT STATION. 
CARE OF THE COWS AFTER THEY WERE BROUGHT TO THE 
STATION. 
When the cows were brought to the Station they were 
isolated from other cattle, in a high, light and airy stable, 
with about 1,500 cubic feet of air space per cow; although 
later several calves which were used in the experiments with 
the cows occupied the same stable. Adjoining the stable was 
a small yard, about one-half acre in area, in which the animals 
were allowed to exercise several hours each day, except in 
very stormy or extremely cold weather. No special treatment 
for the disease was attemipted, but good care and feed were 
afforded at all times. 
Soon after the cows were brought to the Station plans were 
made to begin a series of studies and experiments relating to 
the progress of the disease and its infectiousness at different 
stages of its development. ‘The general purpose of the experi- 
ments was to study: (1) the progress of tuberculosis in cows 
which apparently had the disease in a mild form when the 
studies began; (2) the infectiousness of the disease in different 
stages of development, on calves and young stock when fed 
upon the milk of the cows while closely associated with them; 
(3) the infectiousness of the milk when the calves to which it 
was ted were isolated from the cows. As quite full reports of 
the progress of the experiments have been given in the last 
three annual reports of the Station, only a brief summary of 
the work, with the results obtained, will here be given. 
Karly in the course of these studies plans were made by 
which tuberculin tests and physical examinations’ of the ani- 
mals could be made from time to time. During the first year 
that the cows were under observation the tuberculin tests were 
made from two to three months apart, and during the last three 
years the tests were made twice a year, in the spring and in 
the early fall or winter. A rise of two degrees above the max- 
imum temperature of the animal before injection, occurring 
within twenty-four hours after the injection, is. considered a 
response to the test. All of these tests and examinations ex- 
cept one were made by the College veterinarians. The tuber- 
culin tests from January 26, 1897, to July 31, 1897, were made
