THE ALG m: OF BERMUDA. 13 



Ely's Harbor and Mangrove Hay towards the west end of the 

 group are noted for nothing in particular, but are by no means barren; 

 in the former we found a better growth of Porphyra atropurpurea 

 than elsewhere. Now crossing the land to the shore on the inside of 

 the great hook that this end of the group makes, and going along to 

 the neighborhood of Gibbs Hill light, we come to Jew's Hay and 

 Heron Bay, in both of which good collecting may be had, especially 

 in the latter, with its shallow still water and sunny exposure; we 

 found it very fertile with several species of Gradlaria, Laurencia, 

 Spyridia, Chondria curoilineata and other things. Coming back to 

 Hamilton we may find something at Salt Kettle. The wall of the 

 quay at Hamilton below low tide is well covered with algae, and a big 

 timber float lying there yielded a rich harvest of Polysiphojiia foeti- 

 dissima. This brings us round to the point of beginning.
