The detail of the laws of the different governments regarding 

 the suppression of tuberculosis differs very materially ; but of 

 all these methods that law will be the most effective that subjects 

 all of the cattle to a regularly repeated and intelligent examination ; 

 that most surely prevents animals known to be diseased from being 

 sold or hidden by their owners, or dressed for beef by unprincipled 

 butchers ; that makes it possible to destroy them with the least 

 delay after they are found ; and that divides the expense of doing 

 the work and the loss of the animals with the greatest fairness 

 between those who are the most directly benefited, namely, the 

 owner, the town and the Commonwealth.
