tion by man or for calves or pigs or for the production of butter. 

 The quarantined herd is marked, registered, and kept under 

 government surveillance ; it cannot be parted with for stock uses, 

 but it is at the disposal of the owner to keep it for milk, or fatten 

 at once for the butcher. Finall3 7 every member of this herd is 

 slaughtered under government inspection, and the beef put on 

 the market or sent to the rendering works as may be decided. 

 The system secures the hearty cooperation of dairyman, dealer 

 and government, and while it comes short of the speed and 

 efficiency of a generally applied method of extinction, it is ac- 

 complishing a great work for Denmark, putting an immediate 

 stop to the advance of the disease in the worst infected herds, 

 and placing the latent cases of such herds in a safe seclusion for 

 the rest of their lives. At first the tested herds showed 40 per 

 cent, affected ; now less than 20 per cent. 



The feature which would be likely to work the least satisfactorily 

 in the United States, is the disposal of the sterilized milk as such. 

 It is to be feared that this milk would find but a poor market with 

 us, and if it proved unsalable, the preservation of the reacting 

 herd would be no longer an economic success. 



In Pennsylvania where practically the same method is in force, 

 leaving it in the option of the owner to keep the reacting latent 

 cases and sterilize their milk, or to abandon them to the State, 

 have them appraised and slaughtered with indemnity, the uniform 

 practice has been to accept the latter alternative. Not a single 

 owner, I believe, has elected to keep a herd in quarantine and 

 sell the milk sterilized. The result has been that four times the 

 number of applications come in that the appropriation will war- 

 rant the officials to take in hand. 



A special feature of the Pennsylvania method is the provision 

 that a stockowner can have his herd examined, and tested with 

 tuberculin, at his expense, the State to furnish a certificate setting 

 forth the condition of the animals. In case of infection, the 

 owner has the option of abandoning the reacting ones to the State, 

 to be secluded, or appraised and slaughtered, he meanwhile 

 guaranteeing that he shall introduce no new animals into the 

 herd except by tuberculin test under the direction of the State 

 Board. 



The usual provision is in force that no indemnity is allowed for 

 any animal that entered the state not more than three months
