16 SEA MOSSES. 



" The breaking waves dash high 

 On a stern and rock-bound coast." 



In hunting through the tidal region for plants, 

 hunt everywhere, and collect everything found grow-

 a note of it." If you cannot remember without, carry 

 a small memorandum book and enter in it the 

 habitat of each particular kind as you collect it. 

 The tide pools, that is, the little basins in the rocks 

 out of which the water is never emptied, are 

 the places where the choicest collecting may be had. 

 And the nearer they are to the low tide limits, the 

 more likely they will be to have abundance of vege- 

 table life in them. But do not fail to look, also, 

 under the overhanging curtain of " Rockweed " which 

 shadows the perpendicular sides of the cliffs and 

 great boulders. You will often find some beautiful 

 plants there, as for instance, the Ptilota elegans, 

 the Cladophora rupestris and other smaller "mosses."

 by the side of which the tide currents rush in and

 water forms, all spread out beautifully and displayed
