disease. On tlie oilier hand, tlierc wore some cows which liad been under tlie same 

 treatment as the three niontioned, and these when killed showed evident progress of 

 the disease or. at least, the disease in a most active condition. Thus on the one hand 

 there seems to be improvement and on the other a decline. As long as it is not possible 

 to detect the one from the other before post-mortem, this places the stock-grower in a 

 no better jilight. 



There may be encouragement in the work of de Schweinitz of Washington, who has 

 been successful in producing a serum which in an experimental way has been able to 

 check and even cure tuberculosis. It should be remembered that this is only in its 

 experimental stage, and is not yet available nor practicable for application. It is 

 mentioned to illustrate the trend of thought and the lines along which work is being 

 done. 



In the treatment of humans, the sanitoria of Germany have accomplished wonder- 

 ful results. The treatment in these consists of life in the open air, plenty and 

 substantial food, pure water and suitable exercise, all of which are under the stringent 

 regulations of the physicians in charge. This is, therefore, simply the intelligent ap- 

 plication of hygienic principles. 



BREEDS OF CATTLE AFFECTED. 



At the present time, there is not much said regarding the susceptibility of difierent* 

 breeds to tuberculosis. So far as is known, all breeds are equally susceptible. In the 

 College herd the Shorthorn, the Jersey, the Holstein, the Guernsey, Polled Angus, Red 

 Polled, have alike responded to the tuberculin test. The kind of breed apparently 

 has little influence. 



HISTORY OF TUBERCULOSIS IN THE COLLEGE HERD. 



It has been stated with good reasons that the College herd had suffered severely 

 from tuberculosis previous to 1889, but there is nothing authentic which would give us 

 any adequate notion of the extent of the disease. In 1889 Prof. Davenport made some 

 notes in the herd record-book in regard to the existence of tuberculosis at that time. 



It is my purpose to present these notes practically in toto. 



"Having become known in the autumn of 1899 that the herd was to some extent 

 affected with tuberculosis and that some cases had been known before, it w^as decided 

 that vigorous measures should be taken. 



"A resolution of the Board of Agriculture, passed January 6, 1890, condemned to 

 slaughter every animal suspected of the disease and all related closely to those found 

 affected. It was also deemed advisable to reduce the herd by slaughtering all culls 

 and cross-bred animals at as early a day as practicable to learn, if possible, the limits 

 of this disease. In this plan the Farm Committee of the Board concurred. 



"Under this plan the herd was rapidly reduced in numbers and full notes are herein 

 inserted of all cases. Before this action a few had been sold as culls for shipment 

 to reduce the herd. After discovery of the disease every animal was slaughtered if sold 

 and notes made herein of its condition. Dr. E. A. A. Grange, State Veterinarian, 

 conducted the examinations.

PROF. DAVENPORT'S REPORT OF CASES. 



"Phcrnix 12 began to fail in health in the spring of 1890 and grew very bad. She 

 was giddy by spells and poor and dull. She was slaughtered on suspicion April 23, 

 1890, and was affected with tuberculosis in the right lung. The liver seemed diseased, 

 but the cause was not determined. 



"Calf bj-^ her side was killed the next day. The calf had not been well, but no signs 

 of tuberculosis were discovered upon post-mortem. It is supposed that this sickened 

 condition was due to the milk of the motlier, which had been very offensive for weeks. 



"Imperial Red Rose of DereA'>ent. — This cow rapidly lost flesh after the last calving. 

 She had been examined by H. H. Hinds, President Live Stock Sanitary Commission, 

 and Dr. Grange, State Veterinarian, and others, all of whom believed her to be tuber- 

 culous. Upon post-mortem examination she was found to be badly affected. One 

 lung was grown to the side and tubercles as large as walnuts were found in the lungs. 

 Portions of the lungs had broken down, which seemed to account for the coughing 

 spells she had had weeks previous. This was the first animal slaughtered under the 

 resolution of January 6, 1890, and it took place on the 7th of the month. 



"A calf by her side was also slaughtered, but showed no signs of the disease.
