No. 4.] CATTLE COMMISSIONERS' REPORT. 545 



sanitary regulations and go through the expensive process of 

 properly cleansing and disinfecting stables until all diseased 

 animals within the enclosure have been picked out and removed. 

 Therefore the matter of sanitation becomes especially important 

 in cases where herds have been examined by the Board and the 

 disease removed. 



In all cases where entire herds have been examined by this 

 commission upon voluntary request, the owner has agreed that 

 he "will observe the sanitary regulations prescribed by the 

 Board of Cattle Commissioners, and will not introduce into 

 such herd any animals without having them first subjected to 

 the tuberculin test." After the examination of the herd has 

 been completed, and the diseased animals removed, the Board 

 has given directions for the proper disinfection of the premises, as 

 follows : all animals are to be removed from the barn ; all wood- 

 work with w T hich they have been in direct or indirect contact is 

 to be thoroughly scraped ; all floors, ceilings and walls to be 

 sprinkled with water and thoroughly swept ; after this has been 

 done, live steam, or, failing that, boiling water, is to be applied 

 freely to all parts with which the animals have been in contact ; 

 this having been done and allowed to dry, the premises are to 

 be again scraped and swept ; the buildings are then to be closed 

 as tightly as possible, and subjected to the effects of chlorine 

 gas. This gas can be easily made by treating chloride of lime 

 with crude sulphuric acid diluted with three or four parts of 

 water, in sufficient quantities to thoroughly till all parts of the 

 building, which is then left closed for twelve hours. Follow- 

 ing this, all the woodwork is to be treated with whitewash to 

 which has been added a solution of bi-chloride of mercury, one 

 part of mercury to one thousand parts of water, the application 

 to be made by means of a force pump. When this is dry the 

 premises are ready to be used again. It is desirable that this 

 whitewash should be repeated at convenient intervals, for two 

 or three times. 



It is the intention of the Board to continue the work of the 

 examination of stables, such as has already been inaugurated, 

 and to furnish to parties interested instructions in regard to 

 what sanitary conditions are deemed advisable by the Board, 

 and as to how these ends may be accomplished. 



To this end owners of stoek are advised that any building
