to dispose of the reinaiuiug Devons and the Swiss, and I accordingly 

 sold the Devon cow and calf to Mr. E. O'Rourke of New Brighton,. 

 Pennsylvania and had the Swiss and Devon bulls slaughtered." 



That this measure was not adopted to eradicate or limit the spread 

 of the disease in question seems probable, for in the following para- 

 graph of the report we read : "The keeping of many breeds of 

 animals adds materially to the expense of the farm, as well as to the 

 anxiety and care of the superintendent." At the same time the 

 advisability of keeping representatives of the different breeds of 

 cattle for the benefit of the students was not forgotten. 



From the information obtained through Professor Stockbridge and 

 the preceding quotations we are certain that tuberculosis existed in 

 the college herd ; and that it occasionally caused slight trouble 

 among the animals for a few years afterwards, we may conclude 

 from a section of the farm report which appeared a few years later,, 

 that reads : "The stock has been thrifty and productive. A few 

 animals which fell short of a high standard of excellence have been 

 slaughtered, or disposed of, with full notice of all defects, while 

 others of pure descent and imi'mjieacJiable character have been sold 

 for remunerative prices." 



From this year to 1890 there were occasional deaths in the herd 

 from tuberculosis, but at no time can I learn that there were during 

 one season any considerable number lost. 



In a letter to the President of the college, Professor Brooks under 

 date of January 3, 1893, makes in part the following statement in 

 regard to the condition of the stables and the existence of tuberculo- 

 sis among the cattle : 



" In spite of our utmost attempts to disinfect our barn, it appears 

 to be thoroughly infected with the germs of tuberculosis. The first 

 case of this disease in our barn occurred before 1880, and from that 

 time to the present, losses of valuable animals have occasionally 

 happened. When I assumed responsibility for the management of 

 the college farm, in 1889, I found two animals in the barn affected 

 with tuberculosis. These were slaughtered, and matters were 

 allowed to run until the winter of 1890, and there was little indica- 

 tion of the presence of the disease. 



Becoming somewhat alarmed, in view of the statements of certain 

 veterinarians as to the condition of our herd at this time, Dr. James 

 Law was called in. He made a thorough examination of every 

 animal in the barn, and sent in a report which, as you are aware, 

 was quite reassuring in its character. Two animals slaughtered by
