THE DOG AS A CAEEIER OF PARASITES AND DISEASE. 27 
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.
