Who has not had a vision from some vessel's deck, when he had still his land-legs on, of this great brown apron, drifting half upright, and quite submerged through the green water, clasping a stone or a deep-sea mussel in its unearthly fingers? I have seen it carrying a stone half as large as my head. We sometimes watched a mass of this cable-like weed, as it was tossed up on the crest of a breaker, waiting with interest to see it come in, as if there was some treasure buoyed up by it; but we were always surprised and disappointed at the insignificance of the mass which had attracted us. As we looked out over the water, the smallest objects floating on it appeared indefinitely large, we were so impressed by the vastness of the ocean, and each one bore so large a proportion to the whole ocean, which we saw. We were so often disappointed in the size of such things as came ashore, the ridiculous bits of wood or weed, with which the ocean labored, that we began to doubt whether the Atlantic itself would bear a still closer inspection, and would not turn out to be but a small pond, if it should come ashore to us. This kelp, oar-weed, tangle, devil's-apron, sole-leather, or ribbon-weed, — as various species are called, — appeared to us a singularly marine and fabulous product, a fit invention for Neptune to adorn his car with, or a freak of Proteus. All that is told of the sea has a fabulous sound to an inhabitant of the land, and all its products have a certain fabulous quality, as if they belonged to another planet, from sea-weed to a sailor's yarn, or a fish-story. In this element the animal and vegetable kingdoms meet and are strangely mingled. One species of kelp, according to Bory St. Vincent, has a stem fifteen hundred feet long, and hence is the longest vegetable known, and a brig's crew spent two days to no purpose collecting the trunks of another kind cast ashore on the Falkland Islands, mistaking it for drift-wood. (See Harvey on Algæ.) This species looked almost edible; at least, I thought that if I were starving I would try it. One sailor told me that the cows ate it. It cut like cheese; for I took the earliest opportunity to sit down and deliberately whittle up a fathom or two of it, that I might become more intimately acquainted with it, see how it cut, and if it were hollow all the way through. The blade looked like a broad belt, whose edges had been quilled, or as if stretched by hammering, and it was also twisted spirally. The extremity was generally worn and ragged from the lashing of the waves. A piece of the stem which I carried home shrunk to one quarter of its size a week afterward, and was completely covered with crystals of salt like frost. The reader will excuse my greenness, — though it is not sea-greenness, like his, perchance, — for I live by a river shore, where this weed does not wash up. When we consider in what meadows it grew, and how it was raked, and in what kind of hay weather got in or out, we may well be curious about it. One who is weather-wise has given the following account of the matter.

"When descends on the Atlantic
The gigantic
Storm-wind of the equinox,
Landward in his wrath he scourges
The toiling surges,
Laden with sea-weed from the rocks.
