to the tuberculin test. Especially now when the N. Y. State 

 Veterinary College undertakes to furnish tuberculin free for use 

 in herds in this state, the expense of such a test should not be a 

 serious drawback. The measures to be adopted may be thus 

 enumerated. 



I St. Apply the tuberculin test to the entire herd. 



2d. Remove all animals showing a rise of temperature which 

 indicates tuberculosis. 



3d. Destroy and burn, boil, or deeply bury all cases of the 

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

 cases which are in good condition. (See above.) 



4th. In case of doubt or disturbing influences which may 

 have caused rise of temperature (nearness to calving, heat, ex- 

 posure, concurrent disease, changes in management, etc.), keep 

 the suspected animal apart for three or four weeks and test 

 again. This will almost certainly correct an}- mistake of the 

 first test. 



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

 tests show no indication of tuberculosis the herd may be ac- 

 counted safe. 



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

 a stable let it be vacated and thoroughly disinfected with chloride 

 of lime, 4 ounces to a gallon of water and enough quicklime to 

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

 has been missed. When chloride of lime is objectionable because 

 of its tainting the milk, mercuric chloride may be used in the 

 proportion of one drachm to a gallon of water, to which is added 

 one drachm of sal ammoniac and 5 drachms of common salt. 

 This is much more poisonous than the chloride of lime and must 

 be cautiousl}^ handled during its application. The walls, roof, 

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

 thoroughly scraped, washed and cleaned, all rotten woodw^ork 

 must be removed, and in case of double boarded w^alls, the boards 

 must be removed on one side to permit of a thorough application. 



7th. In making ne^v purchases avoid any herd in which 

 tuberculosis has appeared, or w^hich has had sickness or deaths 

 in recent j^ears. 



8th. Don't purchase from city, suburban nor swill stables.
