This--the illuminating moment--had occurred the trip before, on the return passage. They had just left a place of call on the mainland called Pangu; they were steaming straight out of a bay. To the east a massive headland closed the view, with the tilted edges of the rocky strata showing through its ragged clothing of rank bushes and thorny creepers. The wind had begun to sing in the rigging; the sea along the coast, green and as if swollen a little above the line of the horizon, seemed to pour itself over, time after time, with a slow and thundering fall, into the shadow of the leeward cape; and across the wide opening the nearest of a group of small islands stood enveloped in the hazy yellow light of a breezy sunrise; still farther out the hummocky tops of other islets peeped out motionless above the water of the channels between, scoured tumultuously by the breeze. The usual track of the Sofala both going and returning on every trip led her for a few miles along this reefinfested region. She followed a broad lane of water, dropping astern, one after another, these crumbs of the earth’s crust resembling a squadron of dismasted hulks run in disorder upon a foul ground of rocks and shoals. Some of these fragments of land appeared, indeed, no bigger than a stranded ship; others, quite flat, lay awash like anchored rafts, like ponderous, black rafts of stone; several, heavily timbered and round at the base, emerged in squat domes of deep green foliage that shuddered darkly all over to the flying touch of cloud shadows driven by the sudden gusts of the squally season. The thunderstorms of the coast broke frequently over that cluster; it turned then shadowy in its whole extent; it turned more dark, and as if more still in the play of fire; as if more impenetrably silent in the peals of thunder; its blurred shapes vanished--dissolving utterly at times in the thick rain--to reappear clear-cut and black in the stormy light against the gray sheet of the cloud--scattered on the slaty round table of the sea. Unscathed by storms, resisting the work of years, unfretted by the strife of the world, there it lay unchanged as on that day, four hundred years ago, when first beheld by Western eyes from the deck of a high-pooped caravel.
