 ible animal life, it was full of sound. The steady drain- 

 ino- off of the water caused a constant sibilant snapping 

 as the surface cracked and bubbled. 



With not a spider even darting over the mud, and no 

 subterranean creature peeping above it, it would have 

 been monotonous waiting for the tide to turn, had not 

 a cat-bird kindly entertained me the while. He seemed 

 strangely out of place. AVhy he should have left the 

 briers on the hill-side and wandered thither is hard to
