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 

 m 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.
