WINTER WAYS OF ANIMALS 159 



the top of the beaver house and also prowled 

 along the bottom of the dam. A number of 

 mountain sheep had crossed the pond a day or 

 two before. 



The pond was in a deep gulch and a goodly 

 stream of water out of sight beneath the ice 

 and snow was running into it. The concen- 

 trated outflow burst out over the top of the 

 south end of the dam through an eighteen-inch 

 opening. This pond was frozen over for five 

 months. For these five months the beaver 

 each day had a swim or two in the water under 

 the ice. When hungry he took a section of an 

 aspen from the pile on the bottom of the pond. 

 This was dragged under the ice up into the 

 house, where it afforded a meal of canned green 

 bark. 



Most summer birds fly away from winter. 

 Other birds and a few animals travel a short 

 distance go to a place where food is more 

 abundant although the winter there may not be 

 any milder than in the locality in which they 

 summered. Birds that remain to winter in the 

 locality in which they summered, and most of 

 the animals, too, go about their affairs as usual. 

 They do not store food for the winter or even 

 for the following day. The getting of food in 

 the land of snows does not appear to trouble 

 them.
