they have been fed the milk from a pail. In the experiments 
for the first year and a half the calves were kept in the same 
stable with the cows, and, of course, there was some liability 
that the animals might contract the disease through the breath, 
or food other than the milk. During this period, however, no 
sign of the disease was developed in any of the calves. In some 
_later experiments, two of the calves are being kept in a room 
entirely separate from the cows. 
Feeding calf A with the milk of cows 1344 and I34I.— 
This calf was dropped December 25, 1806, by a vigorous grade 
cow. The dam of the calf was tested with tuberculin on March 
3-4, 1897, but gave no response. This calf was fed the milk 
of cow No. 1344 from January 7 to March 28, 1897. The cali 
was tested with tuberculin January 26-27, and again March 
29-30, 1897, but gave no response to either of the tests. At 
that time, the supply of milk from cow No. 1344 being less 
than the calf seemed to need, it was fed the milk of cow No. 
1341. This cow being quite a heavy milker, the calf was 
limited to about 15 or 16 pounds of milk per day for the first 
month. After this, calf A was given all the milk produced by 
cow No. 1341, which amounted to 20-24 pounds daily, for the 
next two months. Calf A was fed the milk of this cow from 
about April 1, 1897, to July 9, 1898. The calf was castrated in 
May, when about a year and a half old, and was sent to pasture 
July 9, where it remained until about the ist of November, 
1898. Beside the two tuberculin tests made while calf A was 
being fed the milk of cow No. 1 344, several tests were made 
during the year and three months that it was fed the milk 
supply of cow 1341. The first of these tests was made July 
30-31, the second September 27-28, the third December 
17-18, 1897, and the last before the animal went to pasture 
was made on April 11-12, 1898. At no time since we began 
teeding this calf early in January, 1897, has it shown any effects 
from the tuberculin tests, or any physical symptoms that would 
indicate the presence of the disease. When sent to pasture 
in July it was a large, vigorous animal, weighing about 500 
pounds. Early in November this steer was returned to the 
same stable with the tuberculous cows. It was again tested 
with tuberculin December 22-23, 1808, but gave no response. 
During the present winter it is being fattened for beef, and at 
the present time (F ebruary, 1899) the steer is in vigorous con- 
dition, and is laying on flesh quite rapidly.
