On the shores of Salt Lake while the great white gulls disport 

 themselves in the air and on the water, the plump little snowy plover 

 is trotting along the beach gathering his food as he goes. If fright- 

 ened, he dro))s into the deep footprint of a horse and is lost to view, 

 so well does his back match the dull gray surface. Though so small, 

 he is one of the most attractive bits of life in his big landscapes.
