The lake is perfectly clear, with a bottom of yellowish shallow mud, which rests—according to investigations made in 1851—upon a mass of pumice-stone mixed in places with ferruginous sand; and the yellow mud itself is a detritus of pumice-stone. We strip for a swim.
Though at an elevation of nearly 5000 feet, this water is not so cold as that of the Roxelane, nor of other rivers of the north-west and north-east coasts. It has an agreeable fresh taste, like dew. Looking down into it, I see many lame of the maringouin, or large mosquito: no fish. The maringouins themselves are troublesome,—whirring around us and stinging. On striking out for the middle, one is surprised to feel the water growing slightly warmer. The committee of investigation in 1851 found the temperature of the lake, in spite of a north wind, 20.5 Centigrade, while that of the air was but 19 (about 69 F. for the water, and 66.2 for the air). The depth in the centre is over six feet; the average is scarcely four.
Regaining the bank, we prepare to ascend the Morne de la Croix. The circular path by which it is commonly reached is now under water; and we have to wade up to our waists. All the while clouds keep passing over us in great slow whirls. Some are white and half-transparent; others opaque and dark gray;—a dark cloud passing through a white one looks like a goblin. Gaining the opposite shore, we find a very rough path over splintered stone, ascending between the thickest fern-growths possible to imagine. The general tone of this fern is dark green; but there are paler cloudings of yellow and pink,—due to the varying age of the leaves, which are pressed into a cushion three or four feet high, and almost solid enough to sit upon. About two hundred and fifty yards from the crater edge, the path rises above this tangle, and zigzags up the morne, which now appears twice as lofty as from the lake, where we had a curiously foreshortened view of it. It then looked scarcely a hundred feet high; it is more than double that. The cone is green to the top with moss, low grasses, small fern, and creeping pretty plants, like violets, with big carmine flowers. The path is a black line: the rock laid bare by it looks as if burned to the core. We have now to use our hands in climbing; but the low thick ferns give a good hold. Out of breath, and drenched in perspiration, we reach the apex,—the highest point of the island. But we are curtained about with clouds,—moving in dense white and gray masses: we cannot see fifty feet away.
The top of the peak has a slightly slanting surface of perhaps twenty square yards, very irregular in outline;—southwardly the morne pitches sheer into a frightful chasm, between the converging of two of those long corrugated ridges already described as buttressing the volcano on all sides. Through a cloud-rift we can see another crater-lake twelve hundred feet below—said to be five times larger than the Étang we have just left: it is also of more irregular outline. This is called the Étang Sec, or "Dry Pool," because dry in less rainy seasons. It occupies a more ancient crater, and is very rarely visited: the path leading to it is difficult and dangerous,—a natural ladder of roots and lianas over a series of precipices. Behind us the Crater of the Three Palmistes now looks no larger than the surface on which we stand;—over its further boundary we can see the wall of another gorge, in which there is a third crater-lake. West and north are green peakings, ridges, and high lava walls steep as fortifications. All this we can only note in the intervals between passing of clouds. As yet there is no landscape visible southward;—we sit down and wait.

... Two crosses are planted nearly at the verge of the precipice; a small one of iron; and a large one of wood—probably the same put up by the Abbé Lespinasse during the panic of 1851, after the eruption. This has been splintered to pieces by a flash of lightning; and the fragments are clumsily united with cord. There is also a little tin plate let into a slit in a black post: it bears a date,—8 Avril, 1867.... The volcanic vents, which were active in 1851, are not visible from the peak: they are in the gorge descending from it, at a point nearly on a level with the Étang Sec.
The ground gives out a peculiar hollow sound when tapped, and is covered with a singular lichen,—all composed of round overlapping leaves about one-eighth of an inch in diameter, pale green, and tough as fish-scales. Here and there one sees a beautiful branching growth, like a mass of green coral: it is a gigantic moss. Cabane-Jésus ("bed-of-Jesus") the patois name is: at Christmas-time, in all the churches, those decorated cribs in which the image of the Child-Saviour is laid are filled with it. The creeping crimson violet is also here. Fire-flies with bronze-green bodies are crawling about;—I notice also small frogs, large gray crickets, and a species of snail with a black shell. A solitary humming-bird passes, with a beautiful blue head, flaming like sapphire.
All at once the peak vibrates to a tremendous sound from somewhere below.... It is only a peal of thunder; but it startled at first, because the mountain rumbles and grumbles occasionally.... From the wilderness of ferns about the lake a sweet long low whistle comes—three times;—a siffleur-de-montagne has its nest there.
There is a rain-storm over the woods beneath us: clouds now hide everything but the point on which we rest; the crater of the Palmistes becomes invisible. But it is only for a little while that we are thus befogged: a wind conies, blows the clouds over us, lifts them up and folds them like a drapery, and slowly whirls them away northward. And for the first time the view is clear over the intervening gorge,—now spanned by the rocket-leap of a perfect rainbow.
... Valleys and mornes, peaks and ravines,—succeeding each other swiftly as surge succeeds surge in a storm,—a weirdly tossed world, but beautiful as it is weird: all green the foreground, with all tints of green, shadowing off to billowy distances of purest blue. The sea-line remains invisible as ever: you know where it is only by the zone of pale light ringing the double sphericity of sky and ocean. And in this double blue void the island seems to hang suspended: far peaks seem to come up from nowhere, to rest on nothing—like forms of mirage. Useless to attempt photography;—distances take the same color as the sea. Vauclin's truncated mass is recognizable only by the shape of its indigo shadows. All is vague, vertiginous;—the land still seems to quiver with the prodigious forces that upheaved it.
