as our agents outside of this Commonwealth, and this Board will 

 only accept the tests of such men as we approve of. 



All tests are to be made at the expense of the owners or buyers, 

 and not at that of the Massachusetts Cattle Commission. 



Each tested animal must have an ear-tag, furnished by this 

 Board at cost ; the number on the ear-tag must correspond with 

 the number on the certificate ; and the appearance of the animal 

 must also agree with the description of the certificate, otherwise 

 the certificate will be considered valueless. 



You have been approved of by the Massachusetts Board of 

 Cattle Commissioners to test neat cattle to be shipped to Massa- 

 chusetts, and we will continue to accept your tests as long as we 

 are of the opinion that they are being made in a careful and 

 conscientious manner; if at any time, however, we have reason to 

 be dissatisfied with your work, we retain the privilege of sum- 

 marily dropping your name from our list. 



We also request you to keep us informed as to the source of the 

 tuberculin you use, the strength of the solution and size of dose, 

 all of which must meet with our approval. 



Per order, 

 Massachusetts Board Cattle Commissioners.

 Massachusetts from bovine tuberculosis to the greatest practicable 

 extent, the work of testing cattle outside of this State, to be 

 brought in here, should be done in the most careful and efficient

 tuberculin, for dealers and farmers, to be brought into Massa- 

 chusetts, as our agents outside of this Commonwealth, and this 

 Board will only accept the tests of such men as we approve of. 



A printed list of the men we consider reliable will be furnished 

 on application. This list may be revised from time to time, as 

 new applicants may be added or men who prove either dishonest 

 or incompetent are dropped from it. 



All tests are to be made at the expense of the owners or buyers 

 of the animals, and not at that of the Massachusetts Cattle 

 Commission. 



All neat cattle over six months old brought into the State pur- 

 porting to have been tested will be quarantined and tested, unless
