 the inside of the bark and eat it. The grizzly 

 never does these things. This pulp, however, is used 

 by some of the Indians, who make a kind of bread 

 out of it.

 who is an expert fisherman. On the Pacific slope of 

 the Rocky Mountains almost every stream has, or 

 used to have, its runs of salmon, these fish making

They come from undiscovered regions of the sea in 

 uncountable billions. In untold millions they enter 

 the mouths of the great rivers. They turn off into each

 fill the tributaries of these tributaries. And finally one 

 finds them, still in their hundreds, filling the pools
