Once in for the winter, the bear is likely to stay

 is not heavy enough greatly to deaden his senses. 

 Hunters, trappers, floods, and snow-slides have 

 driven grizzlies from their dens during every stage 

 of hibernation, and in each case a moment after 

 the bear came forth his senses were as alert as

 his normal manner. 



Prospectors in Jefferson Valley, Montana, told 

 me of staking claims and starting to drive a tunnel 

 early one December. A day or two after they be-

 den and scamper away on the mountain-side. They 

 tracked him to the place where he had holed up 

 again. It was their belief that the noise or the jar 

 of their shots had awakened and re-awakened the
