80 Rhodora [May 
Sargassum is used in Bermuda for fertilizer as is Laminaria with us, 
and it is an important factor in agriculture. To one who has seen it 
only as scattered floating strips, the amount thrown ashore during 
a blow is astonishing. At the head of the narrow Inlet, near Flatts 
Village, I have known more than a hundred cartloads to be obtained 
from the mass brought in by one northwesterly gale. In my visits 
to Bermuda, April-May, 1912, and July—Sept., 1913, I was busy with 
other algae, and noticed only incidentally the floating forms; but one 
of the principal objects of my visit in Nov.-Dec., 1915, was to observe 
these floating forms. For this I had good facilities, thanks to Prof. 
E. L. Mark, Director, and Dr. W. J. Crozier, Resident Naturalist, of 
the Bermuda Biological Station. All facilities of the Station at 
Agar’s Island were at my disposal. I lived at the island, collecting at 
its shores, and by excursions in motor boats in various directions. 
As already noted, the floating material is sometimes in scattered 
irregular patches, but when there is any wind, it forms narrow strips, 
in the line of the direction of the wind. This is noted by Bérgesen, 
Sp. Sarg., p. 12. “The Gulfweed is nearly always found in long nar- 
row rows arranged in the direction of the wind, and at a right angle to 
the moving of the sea.” The last phrase is rather ambiguous, possibly 
misleading. The strips are at right angles to the crests of the waves, 
but in the line of their motion, which is of course the same as that of 
the wind. He says further, “The Sargasso floats frequently so near the 
surface that tips of the leaves become emerged when moved by the 
sea.” ‘This is an exact description of the appearance in rough or even 
slightly moving water. In calm water one sees that a frond, as a 
whole, is of a slightly less specific gravity than the water; the stem 
lies just below the surface, and as the stiff leaves are radially arranged, 
those on one side project above the surface, from one to three cm., 
thickly set over the whole patch, much like the peduncles of some 
flowering plant, Elodea or Potamogeton. It is only in smooth water, 
and when the observer is nearly on a level with the water, that this 
is noticeable, but here it is quite striking. The color is quite light, 
yellowish olive; distinctly lighter than that of the attached species 
found in Bermuda. It is darker in the lower part of the individual. 
There are several attached species at Bermuda, S. lendigerum (L.) 
Agardh being the commonest, and found on exposed shores all around 
the islands. The same storms that bring ashore the pelagic forms, tear 
off fragments or even whole plants of the attached forms, which may
