that it leaked through the earth into the den. 

 Again driven forth from his den, the bear so 

 his tracks in the snow showed after one pause 

 climbed to another den on the mountain-side 

 about two miles distant. 



The grizzly spends about one third of each year 

 in hibernation. He may use the same den year after 

 year, repairing and reshaping it; or perhaps he will 

 dig a new one. Sometimes he goes outside his own 

 territory for a den to his liking. He is sometimes 

 driven forth during hibernation by landslides as 

 well as by snow-slides and floods. 



A grizzly is strongly attached to his home terri- 

 tory and spends most of his time in it. Occasion- 

 ally, and in exceptional cases regularly, he wan- 

 ders far away. A scarcity of food may cause him 

 to leave home temporarily; or excessive food else- 

 where may attract him. 



Bears and lions are not neighborly, and at best 

 each ignores the other; but one bear I knew fol- 

 lowed a lion for weeks, and others have occasion- 

 ally done likewise, profiting by the food-supply 

 the excessive killing of the lion. Here was unusual 

 tolerance, almost friendly association, between 

 antagonistic wild folk.
