A Photographic Expedition 145 



bears had been feeding, as was shown by the grass that had 

 been nipped and the holes that had been dug for roots. 



For some hours I waited in the bushes and fought gnats 

 and mosquitoes. I saw several black bears pass along the 

 hillside, but not a grizzly showed his nose until after the 

 sun had set and the little marsh in the park was covered 

 with a mantle of fog. Suddenly then, far up the, trail,

I watched closely to see if he acted diflFerently from
