 are left them. What if there were enough gan- 

 glia to enable them to dream of their past higher 

 life, in the long intervals of patient waiting!

 cables, so tough that they often defy our utmost 

 efforts to tear a specimen away. How secure these

 they have enemies which make havoc among them. 

 At high tide fishes come and crunch them, shells

 waiting to set their file-like tongues at work, which 

 mercilessly drill through the lime shells, bring-
