PERIWINKLE AND EGG-CASES 
winkle remind one of a beautiful necklace. The air 
bubbles rising from the sand or mud as the wave re- 
cedes mark the entrance to the burrows of worms. 
Stamp hard on the sand. A little fountain of water 
announces the abode of the soft clam. Watch the sand 
at the edge of the rippling water. The mole-crab may- 
be seen scuttling to cover. In the little hollows between 
rocks a rock-crab or a green-crab may be found on 
guard. 
For collecting in the pools and shallow water a fine- 
meshed net is desirable. Many of the animals can be 
caught and placed in glass dishes of sea water for close 
observatic *n.
