About half-way between the summit and base of the mountain, a deep longitudinal hollow lay in its track—into which the stream was precipitated, in a clear, curving cascade.
This singular hollow resembled the crater of an extinct volcano—in the circumstance that on all sides it was surrounded by a precipice facing inward, and rising two hundred feet sheer from the level below. It was not of circular shape, however—as craters generally are—but of the form of a ship, the stream falling in over the poop, and afterwards escaping through a narrow cleft at the bow.
Preserving the simile of a ship, it may be stated that the channel ran directly fore and aft, bisecting the bottom of the valley, an area of several acres, into two equal parts—but in consequence of an obstruction at its exit, the stream formed a lagoon, or dam, flooding the whole of the fore-deck, while the main and quarter-decks were covered with a growth of indigenous timber-trees, of appearance primeval.
The water, on leaving the lagoon, made its escape below, through a gorge black and narrow, bounded on each side by the same beetling cliffs that surrounded the valley. At the lower end of this gorge was a second waterfall, where the stream again pitched over a precipice of several hundred feet in height; and thence traversing the slope of the mountain, ended in becoming a tributary of the Montego River.
The upper cascade precipitated itself upon a bed of grim black boulders; through the midst of which the froth-crested water seethed swiftly onward to the lagoon below.
Above these boulders hung continuously a cloud of white vapour, like steam ascending out of some gigantic cauldron.
When the sun was upon that side of the mountain, an iris might be seen shining amidst the fleece-like vapour. But rare was the eye that beheld this beautiful phenomenon: for the Duppy’s Hole—in negro parlance, the appellation of the place—shared the reputation of the Jumbé Rock; and few were the negroes who would have ventured to approach, even to the edge of this cavernous abysm: fewer those who would have dared to descend into it.
Indeed, something more than superstitious terror might have hindered the execution of this last project: since a descent into the Duppy’s Hole appeared an impossibility. Down the beetling cliffs that encompassed it, there was neither path nor pass—not a ledge on which the foot might have rested with safety. Only at one point—and that where the precipice rose over the lagoon—might a descent have been made: by means of some stunted trees that, rooting in the clefts of the rock, formed a straggling screen up the face of the cliff. At this point an agile individual might possibly have scrambled down; but the dammed water—dark and deep—would have hindered him from reaching the quarter-deck of this ship-shaped ravine, unless by swimming; and this, the suck of the current towards the gorge below would have rendered a most perilous performance.
It was evident that some one had tempted this peril: for on scrutinising the straggling trees upon the cliff, a sort of stairway could be distinguished—the outstanding stems serving as steps, with the parasitical creepers connecting them together.
Moreover, at certain times, a tiny string of smoke might have been seen ascending out of the Duppy’s Hole; which, after curling diffusely over the tops of the tall trees, would dissolve itself, and become invisible. Only one standing upon the cliff above, and parting the foliage that screened it to its very brink, could have seen this smoke; and, if only superficially observed, it might easily have been mistaken for a stray waif of the fog that floated above the waterfall near which it rose. Closely scrutinised, however, its blue colour and soft filmy haze rendered it recognisable as the smoke of a wood fire, and one that must have been made by human hands.
