form is possible ; without it practically nothing is possible. Undue 

 sentiment for the dog should not be allowed to blind us to his dan- 

 gerous possibilities as a carrier of diseases and parasites or to stand 

 in the way of effective measures for the protection of human life and 

 health. The time seems to be at hand when the stray dog, the sheep- 

 killing cur, the vagrant carrier of dangerous parasites and of the 

 horrors of rabies should be exterminated. The destruction of such 

 dogs would mean a saving of hundreds of lives and the saving and 

 making of millions of dollars.
