160 STORRS AGRICULTURAL EXPERIMENT STATION. 
in July, 1898, calf B was fed the milk of cow No. 1343. This 
calf was not a vigorous eater, and at times refused single 
feeds of milk. The calf seemed healthy, and ate hay 
readily. When a year old the animal was thought to be 
rather small for its age, but this may have been due to the 
fact that it had always refused grain feeds. ‘This animal 
was castrated in May, 1898, and was sent to pasture with 
steer A in the early part of July. It was returned to the same 
stable with the cows early in November, and started upon a 
heavy grain ration with a view to fattening for beef. Decem- 
ber 22-23, this steer gave a marked response to the tuberculin 
test (see temperature, Table 36, page 153). In addition to 
the marked rise in temperature, the steer showed physical 
symptoms by a roughness of the coat, shivering, and twitching 
of the muscles. Steer B was killed and carefully examined by 
the College Veterinarian, Dr. Mayo, December 20);:1 3060.91 He 
only trace of the disease found was a few small tubercles in 
one of the pharyngeal glands of the throat. ‘T‘he disease was, 
with little doubt, of recent origin. While, of course, there is 
no proof as to how this animal contracted the disease, it seems 
quite probable that the germs may have entered the system in 
the breath after the animal was returned to the stable early in 
November, 1808. 
feeding Calf C with the milk of Cow 1337.—This was a heifer 
calf, dropped by cow No. 1337, April 5, 1897. The calf was 
allowed to suckle its dam until about six months old. About 
October 1 the calf was weaned, but was fed the milk of its 
dam until January, 1898. It was then gradually put upon a 
skim-milk diet, and was placed in the college herd with the 
intention of raising the calf for dairy purposes. The animal 
_ was tested with tuberculin July 30-31, September 27-28, and 
December 17-18, 1897, and again December 22-23; 1898.0) Phe 
heifer produced her first calf December 5, 1899, and has con- 
tinued to give a fair flow of milk. She was tested with 
tuberculin June 2-3 and December: 7-8, 1899, and April 25-26, 
1900, but gave no response. 
feeding Calf D with the milk of Cow 1344.—This was a bull 
calf, dropped by a vigorous grade cow, November 29, 1897. 
It was fed the milk of cow No. 1344 from early in December, 
1897, till February, 1899, after which it was given a grain and
