with the herd, and a strict quarantine observed, in a short 

 time the entire State would be cleared up, and that the herds 

 in the State would remain free from disease. 



Those who object to this method say that the cost is too 

 great. While it might be possible in certain herds, yet in 

 many barns it is impossible to thoroughly disinfect and 

 renovate them without great expense to the owner. It is 

 difficult to pick out all the diseased animals in one test, and 

 if all animals that reacted to the test were condemned, many 

 of the best milking strains might be destroyed, and whole 

 families that it had taken years of labor to produce would be 

 wiped out of existence. 



About a year ago a number of valuable herds in the State 

 were tested with tuberculin, under promise from the owners 

 to strictly observe certain conditions. Among those tested 

 was one belonging to Mr. A, consisting of 81 animals. This 

 herd was carefully tested, and the figures submitted to this 

 Board, and 28 animals considered certainly diseased by the 

 Board were condemned and destroyed, and a number were 

 held for retest. The animals held for retest were kept in a 

 separate pasture, and were not allowed to mingle with the 

 rest of the herd. Of these, 13 animals were retested, con- 

 demned b}^ the Board and killed, the others passed as sound. 

 Before these cattle were allowed to join the hei-d the barn 

 had been thoroughly disinfected, in accordance with the fol- 

 lowing statement : — 



Owner's Statement. 



We disinfected the barns in the following manner, August 10, 

 11 and 12. They were thoroughly washed with soap and water, 

 the corners of cribs and stalls received careful attention. The 

 floor of the stalls was relaid in new plank throughout. We then 

 used Labaraque's disinfecting chlorinated solution in full strength 

 as a disinfectant. We used 8 or 10 barrels of it, and every par- 

 ticle of wood received a generous quantity, after which the win- 

 dows and doors were stopped securely and chlorine gas was gen- 

 erated for five or six hours. After this the stalls, sides and over- 

 head received a coat of paint or vai'nish. This barn, in which 

 are always kept the cows in milk, ties up 50 head. It is 101 feet 

 long by 46 wide, and 9 foot post. There are 9 windows on the 

 west side, and 8 on the east side, each 5 by 3 feet, besides win-
