THE GUIDE T< ) NATURE 



every day, and to which we pay no 

 heed. 



Xku.ik 1'.. Pendergast. 



P. S. — This may seem a strange line 

 "t* argument from one who has a pas- 



sionate love and sympathy for all ani- 

 mals; who believes that we are not 

 the onlv animals who have souls ; who 



never loses an opportunity to urge 

 camera hunting instead of rifle hunt- 

 ing; and to whom tin- cry of a hurt 

 creature echos long: hut I firmly be- 

 lieve that injustice, exaggeration and 

 hysterical sentiment do more harm to 

 the cause for which the .\.\ and the 

 Humane Societies stand, than all the 

 indifference which they encounter.
