arranged for ventilation. An air duct brings fresh air to eacb 

 manger from outside the barn. 



I use the Buckley device for water ; two cows drink from each 

 bucket . 



All liquid manure is conveyed to a large tank outside the barn, 

 and the manure cellar is well ventilated and well drained. 



The herd belonging to Mr. E, after being tested and 

 cleaned up in October, 1894, was retested on March 17 and 

 18, 1896. There were 80 animals in the herd, 78 of which 

 were tested, 2 animals having a temperature too high at the 

 time to be injected. Fourteen animals reacted or showed a 

 suspicious rise in temperature ; they were immediately sepa- 

 rated from the remainder of the herd, were again retested June 

 19 and 20, at which time two were released, three were con- 

 demned and 9 were continued in quarantine. On Oct. 7, 8 and 

 9 these 9 quarantined animals were tested and condemned. 



On Aug. 16 and 17 64 of the original herd and 1 animal 

 which had been introduced recently were tested. None of 

 the original animals reacted to the test, while the animal 

 which had been introduced from outside reacted and was 

 condemned, and upon post-mortem was found to be tuber- 

 culous. 



From these records it will be seen that it requires not one 

 examination alone, but more than one test and most thorough 

 disinfection and renovation before a herd can be pronounced 

 free from disease. 



It is, perhaps, not amiss at this time to call the attention 

 of your honorable body to the pamphlet issued jointly by 

 the Board of Agriculture and the Hatch experiment station, 

 on the work done by Professor Bang of Copenhagen. 



A similar experiment is reported by Dr. Cooper Curtice 

 in the "Journal of Comparative Medicine" for August, 

 1896. He reports that a valuable herd of Guernseys, be- 

 longing to Mr. R. A. Bordon of Easton, N. Y., were badly 

 aftected with tuberculosis. This herd was handled in the 

 manner recommended by Professor Bang, with successful 

 results. In referring to the matter Dr. Curtice says : — 



The loss to Mr. Bordon and the State, through tuberculosis 

 causing death of cattle, through the slaughter and separation of
