"In captivity bears may, or may not, hibernate. 

 As a rule they ' sleep ' for more or less varying pe- 

 riods during severe weather. One authority states 

 the grizzly has been known to sleep from sixty to 

 seventy-five days and during that time it was not 

 difficult to awaken him. Black bears frequently 

 pass the winter without evidence of even drowsi- 

 ness. Others awake at irregular intervals, and after 

 feeding lightly, return to their slumber." 



The winter life of many animals is stem and 

 strange. During the autumn the beaver stores up a 

 food-supply for use when the pond is closed over 

 with ice. The cony harvests hay for his winter food. 

 Numbers of animals hunt food each day in the 

 snow. But the woodchuck and the bear hiber- 

 nate, that is, they fast and sleep in a den during the 

 winter.
