the ends of the toes. The black's curved claws are 

 much used in climbing; the grizzly's claws are used 

 mostly for digging. 



The largest grizzly-track that I have measured 

 was slightly more than thirteen inches long, and 

 seven and one half inches wide at the widest point. 

 These measurements did not include the claw- 

 marks. In places where this bear had slipped on 

 snowy or muddy ground the track with claw- 

 marks was of most formidable appearance. Many 

 of the big Alaskan grizzlies have large feet, some- 

 times making a track eighteen inches in length. 

 However, in the Rocky Mountains I have seen a 

 large track that had been made by a compara- 

 tively small bear. More than once I have seen 

 bears weighing less than four hundred pounds 

 whose feet were larger than those of other bears 

 who weighed upwards of six hundred pounds. A 

 large grizzly bear track does not necessarily indi- 

 cate that it is the track of a large bear. 



There is marked difference in the ordinary ways 

 of the black and the grizzly. The grizzly is ener- 

 getic, thorough, works hard, and takes life rather 

 seriously; while the black bear is lazy, careless, 

 does no more work each day than is necessary, and
