All reference to the nature, causes, symptoms and post-mortem 

 appearances of tuberculosis, together with the infectiousness of the 

 milk of tuberculous cows has been purposely omitted in this bulletin 

 as they have been discussed in previous bulletins of the station and 

 in a paper published in the college catalogue for 1892.* 



Considering the number of animals in the college herd tested with 

 tuberculin and the autopsies made, it was thought that certain reliable 

 conclusions could be drawn without reviewing the work of others 

 upon this subject ; consequently we shall confine ourselves to the 

 history of the herd, the tests with tuberculin, the results of the 

 autopsies and the conclusions to be drawn from a careful study of the 

 subject. 



DESCRIPTION OF THE STABLE AND HISTORY 

 OF THE HERD. 



In 18G9 there was built on the college farm the barn recently 

 destroyed by fire. In the college report for the following year it is 

 described in part as follows : " It is a substantial but plain structure 

 of wood, upon a granite foundation. The cellar for manure extends 

 under the entire main building, and is one hundred feet in length, 

 fifty feet wide, and ten feet deep. It is accessible with teams at the 

 west end by two nearly level drive-ways twelve feet in width, and is 

 well lighted and ventilated by windows on the north and south sides. 

 The lower story immediately over the cellar is eight feet high in the 

 clear and is well lighted by windows on the north, west and south. 

 Ventilation is secured by flues in each corner which extend to the 

 roof, and by the upper sashes of the windows which are hung with 

 weights. On the east end of this floor is a room for roots.
