THE AMERICAN BLACK BEAR 217 



in length, arid nearly straight. Grizzlies do not 

 and cannot climb trees. On the other hand, the 

 black bear's claws are shorter, more curved, and 

 thicker at the base, which enables them to go up a 

 huge tree very much as a cat or a squirrel would, 

 and also a slim one just large enough to sustain 

 their weight. 



In conclusion would say that I do not pretend 

 to know all about black bears no one man can ; 

 but I have found them sufficiently interesting to 

 have taken a great deal of pleasure in devoting 

 a long study to them, and have here set down 

 only what I know to be facts.
