makes its dairy and breeding herds the depository of the reacting 

 animals that otlier states wisely exclude. The sifting process 

 goes on at Buffalo and other centres and the New York herds are 

 loaded with the rejected, diseased animals. Under the operation 

 of this, and the denial of indemnity for animals slaughtered, it 

 will be wonderful, if the New York stock owner is not soon 

 roused up from his idle dream of fancied security, by a great ex- 

 tension of the infection. 



Generally Applicable Measures. Under any system many 

 special rules will be demanded in individual cases, which it will 

 require the skill of the expert sanitarian to apply, and which 

 cannot be referred to here. The following are generally applicable 

 whether by the owner in his particular herd, or by the State or 

 other authority dealing with the subject. 



i st. On discover}' of a case of tuberculosis, test the whole herd 

 with tuberculin. (See Tuberculin Testing.) 



2d. Remove all animals that show a typical reaction. 

 3d. Destroy and burn, boil or deeply bury all cases ot the dis- 

 ease, unless it is decided to form an isolated herd of latent cases 

 which are in good condition and apparent good health. 



4th. In case of doubt or disturbing influence which ma}' have 

 caused rise of temperature (calving, heat, exposure, concurrent 

 disease, changes in management, etc.), keep the, suspected ani- 

 mal apart for four weeks and test again. 



5th. Repeat the test every six months, and if two successive 

 tests show no indication of tuberculosis, the herd may be accounted 

 sound. 



6th. As soon as tuberculous animals have been removed from 

 a stable, let it be vacated and thoroughly disinfected with chloride 

 of lime, 4 ozs. to 1 gallon of water, and enough quick lime to 

 make a good whitewash which will show if even a square inch is 

 missed. When chloride of lime is objectionable because of its 

 tainting the milk, use mercuric chloride 1 dr. to 1 gallon water, 

 with enough sal ammoniac to make it freely soluble. The roof, 

 walls, and especially the floor, gutter and feeding trough must be 

 first thoroughly scraped, washed and cleaned, all rotten wood 

 work must be removed, and, in case of double boarded walls, the 

 boards must be removed on one side to permit of a thorough ap- 

 plication. Utensils should be scalded and dressed with carbolic
