examined then by agents of the Board and appraised and 

 killed by them if their condition demands it. 



Third. — Testing with tuberculin entire herds, at the re- 

 quest of the owners, to determine which animals are infected 

 and which, are healthy, with a view to entirely eradicating 

 tuberculosis from the herd. 



First. — The maintenance of quarantine regulations. All 

 persons bringing cattle into Massachusetts must have a per- 

 mit from the Cattle Commissioners, except for those coming 

 to the stock yards at Brighton, Watertown and Somerville, 

 which are considered quarantine stations, and are in con- 

 stant charge of a member of the commission. 



All cattle except calves under six months old and beeves 

 for immediate slaughter must be tested with tuberculin by a 

 veterinarian acceptable to the Board, at the expense and 

 risk of the owner, either before shipment or after arrival at 

 their destination. Cattle brought to the stock vards are 

 identified and released by the commissioner in charge, upon 

 certificate of tuberculin test ; the animals are identified by 

 an ear tag furnished by the commission ; the number on the 

 tag must agree with the number on the certificate. Animals 

 that have not been tested, upon arrival at the stock yards 

 are held and tested by the Cattle Commission, and any that 

 fail to pass the test are held for a week and retested ; if an 

 animal reacts a second time, it is deemed to be tuberculous, 

 and is killed. Formerly, all animals that reacted the first 

 time were killed, but some that gave an apparent reaction 

 on the first test were found to be free from disease on post- 

 mortem, and the State had to pay for them. Under the 

 present system, a creature that reacts to the second test is 

 invariably found to be tuberculous on autopsy.
