Book excerpt: Excerpt from Dansk Botanisk Arkiv, Vol. 3: Udgivet Af Dansk Botanisk Forening At St. Thomas I have dredged in the sea around Water Island. At a depth of about 10 fathoms and upon sandy, loose bottom a vegetation of Udotea and Halimeda was found, together with several Floridae. At St. Croix the dredgings were mostly not successful on account of the coral reefs which almost entirely surround the island. Only in the sea near Buck Island have more successful dredgings been undertaken. I much regret that I have not succeeded in dredging in deeper water than about 20-25 fathoms; as pointed out in the introduction to the Chlorophycae section, my attempts at this were negative, the dredge being immediately lost in the rocky bottom. But it is not only in deep water that the Red Alg occur; also in shallow water near the shore they are often found in great numbers. In connection with this may also be borne in mind the rich algal vegetation upon the roots of the mangroves and among which the red alg are very prominent.) With regard to the physiographical details, coral reefs, depths etc. and also to localities visited, reference should be made to the introduction to the section on the Chlorophycae; in this part moreover a chart is published showing the coral reefs, depths etc. in the sea surrounding the islands.
