We rowed away, toward our island paradise. But instead of going straight home, we turned into a deep cove called Ance Maurice—all coves in the French islands are called Ances—where was something to be seen, and not to be forgotten again. We grated in, over a shallow bottom of pebbles interspersed with gray lumps of coral pulp, and of Botrylli, azure, crimson, and all the hues of the flower-garden; and landed on the bank of a mangrove swamp, bored everywhere with the holes of land-crabs. One glance showed how these swamps are formed: by that want of tide which is the curse of the West Indies.
At every valley mouth the beating of the waves tends all the year round to throw up a bank of sand and shingle, damming the land-water back to form a lagoon. This might indeed empty itself during the floods of the rainy season; but during the dry season it must remain a stagnant pond, filling gradually with festering vegetable matter from the hills, beer-coloured, and as hideous to look at as it is to smell. Were there a tide, as in England, of from ten to twenty feet, that swamp would be drained twice a day to nearly that depth; and healthy vegetation, as in England, establish itself down to the very beach. A tide of a foot or eighteen inches only, as is too common in the West Indies, will only drain the swamp to that depth; and probably, if there be any strong pebble-bearing surf outside, not at all. So there it all lies, festering in the sun, and cooking poison day and night; while the mangroves and graceful white roseaux [{115a}] (tall canes) kindly do their best to lessen the mischief, by rooting in the slush, and absorbing the poison with their leaves. A white man, sleeping one night on the edge of that pestilential little triangle, half an acre in size, would be in danger of catching a fever and ague, which would make a weaker man of him for the rest of his life. And yet so thoroughly fitted for the climate is the Negro, that not ten yards from the edge of the mud stood a comfortable negro-house, with stout healthy folk therein, evidently well to do in the world, to judge from the poultry, and the fruit-trees and provision-ground which stretched up the glen.
Through the provision-ground we struggled up, among weeds as high as our shoulders; so that it was difficult, as usual, to distinguish garden from forest. But no matter to the black owner. The weeds were probably of only six weeks’ growth; and when they got so high that he actually could not find his tanias [{115b}] among them, he would take cutlass and hoe, and make a lazy raid upon them, or rather upon a quarter of them, certain of two facts; that in six weeks more they would be all as high as ever; and that if they were, it did not matter; for so fertile is the soil, so genial the climate, that he would get in spite of them more crop off the ground than he needed. ‘Pity the poor weeds. Is there not room enough in the world for them and for us?’ seems the Negro’s motto. But he knows his own business well enough, and can exert himself when he really needs to do so; and if the weeds harmed him seriously he would make short work with them. Still this soil, and this climate, put a premium on bad farming, as they do on much else that is bad.
Up we pushed along the narrow path, past curious spiral flags [{115c}] just throwing out their heads of delicate white or purple flower, and under the shade of great Balisiers or wild plantains, [{115d}] with leaves six or eight feet long; and many another curious plant unknown to me; and then through a little copse, of which we had to beware, for it was all black Roseau [{115e}]—a sort of dwarf palm some fifteen feet high, whose stems are covered with black steel needles, which, on being touched, run right through your finger, or your hand, if you press hard enough, and then break off; on which you cut them out if you can. If you cannot, they are apt, like needles, to make voyages about among the muscles, and reappear at some unexpected spot, causing serious harm. Of all the vegetable pests of the forest, none, not even the croc-chien, is so ugly a neighbour as certain varieties of black Roseau.
All this while—I fear I may be prolix: but one must write as one walked, stopping every moment to seize something new, and longing for as many pairs of eyes as a spider—all this while, I say, we heard the roar of the trade-surf growing louder and louder in front; and pushing cautiously through the Roseau, found ourselves on a cliff thirty feet high, and on the other side of the island.
Now it was plain how the Bocas had been made; for here was one making.
Before us seethed a shallow horse-shoe bay, almost a lake, some two hundred yards across inside, but far narrower at the mouth. Into it, between two lofty points of hard rock, worn into caves and pillars and natural arches, the trade-surf came raging in from the north, hurling columns of foam right and left, and then whirling round and round beneath us upon a narrow shore of black sand with such fury that one seemed to see the land torn away by each wave. The cliffs, some thirty feet high where we stood, rose to some hundred at the mouth, in intense black and copper and olive shadows, with one bright green tree in front of a cave’s mouth, on which, it seemed, the sun had never shone; while a thousand feet overhead were glimpses of the wooded mountain-tops, with tender slanting lights, for the sun was growing low, through blue-gray mist on copse and lawn high above. A huge dark-headed Balata, [{116a}] like a storm-torn Scotch pine, crowned the left-hand cliff; two or three young Fan-palms, [{116b}] just ready to topple headlong, the right-hand one; and beyond all, through the great gateway gleamed, as elsewhere, the foam-flecked hazy blue of the Caribbean Sea.
We stood spellbound for a minute at the sudden change of scene and of feeling. From the still choking blazing steam of the leeward glen, we had stepped in a moment into coolness and darkness, pervaded by the delicious rush of the north-eastern wind; into a hidden sanctuary of Nature where one would have liked to build, and live and die: had not a second glance warned us that to die was the easiest of the three. For the whole cliff was falling daily into the sea, and it was hardly safe to venture to the beach for fear of falling stones and earth.
Down, however, we went, by a natural ladder of Matapalo roots, and saw at once how the cove was being formed. The rocks are probably Silurian; and if so, of quite immeasurable antiquity. But instead of being hard, as Silurian rocks are wont to be, they are mere loose beds of dark sand and shale, yellow with sulphur, or black with carbonaceous matter, amid which strange flakes and nodules of white quartz lie loose, ready to drop out at the blow of every wave. The strata, too, sloped upward and outward toward the sea, which is therefore able to undermine them perpetually; and thus the searching surge, having once formed an entrance in the cliff face, between what are now the two outer points, has had nought to do but to gnaw inward; and will gnaw, till the Isle of Monos is cut sheer in two, and the ‘Ance Biscayen,’ as the wonderful little bay is called, will join itself to the Ance Maurice and the Gulf of Paria. In two or three generations hence the little palm-wood will have fallen into the sea. In two or three more the negro house and garden and the mangrove swamp will be gone likewise: and in their place the trade-surf will be battering into the Gulf of Paria from the Northern Sea, through just such a mountain chasm as we saw at Huevos; and a new Boca will have been opened.
But not, understand, a deep and navigable one, as long as the land retains its present level. To make that, there must be a general subsidence of the land and sea bottom around. For surf, when eating into land, gnaws to little deeper than low-water mark: no deeper, probably, than the bottoms of the troughs between the waves. Its tendency is—as one may see along the Ramsgate cliffs—to pare the land away into a flat plain, just covered by a shallow sea. No surf or currents could nave carved out the smaller Bocas to a depth of between twenty and eighty fathoms; much less the great Boca of the Dragon’s Mouth, between Chacachacarra and the Spanish Main, to a depth of more than seventy fathoms. They are sunken mountain passes, whose sides have been since carved into upright cliffs by the gnawing of the sea; and, as Mr. Wall well observes, [{117}] ‘the situation of the Bocas is in a depression of the range, perhaps of the highest antiquity.’
