EXTRACTS FROM THE LOG OF THE EOLIS. 



BY JOHN B. HENDERSON, JR. 



The following extracts taken from the log-book of the Eolis are 

 offered to the NAUTILUS readers at the editor's suggestion. The 

 Eolis is a fifty-foot motor cruising yacht built by the writer es- 

 pecially for the purpose of dredging, and is provided with hoisting 

 machinery, etc. At the time of these entries in the log the boat 

 was cruising in south Florida waters, with Key West, and later, 

 Tortugas, as headquarters. Mr. George H. Clapp, of Pittsburgh, 

 was on board during both cruises. The passages from the log are 

 taken quite at random : 



"April 18, 1910" (in the Hawk Channel). "... coming in 

 sight of Loue Key, a mere patch of coral sand on an exposed bit of 

 the outer Florida Reef, we decide to try for some reef collecting, the 

 tide being favorable. We run the Eolis almost to the key on the 

 lee side, but with breakers all about us. The Captain, Clapp and I 

 go ashore in the tender, leaving the Eolis rolling in uncomfortably 

 shoal water. It is difficult here to record the first impressions of 

 this our first experience on a tropical reef. At last the fine ones are 

 to be had for the picking. In nervous haste we turn over the coral 

 slabs and inspect their under sides. There they are, bright, shin- 

 ing, alive and beautiful : Cypraea cinerea and spurca, Conns mus 

 and floridana, Mitra barbaderis and nodulosa, one excellent specimen 

 of Mitra fergusoni, Cassis, Pisania, Trivia, Olivet, Olivellu, and so 

 on. The wash of the surf over the coral rocks where we are col- 

 lecting, deprives us, I am sure, of many specimens, both by hiding 

 them from sight and by washing them away. . . . Our catch, in 

 two rather strenuous hours' work, is amazing in quantity and quality 

 . . . arrive in Key West at 3 p. m."
