The land-wind was blowing in from the ocean, and, according to the forecast of Old Bill, a great practical meteorologist, it promised ere long to become a gale. It was already sufficiently violent, and chill to boot, to make the situation on the summit of the dune anything but comfortable. There was no reason why they should make their couch upon that exposed prominence. Just on the landward side of the hillock itself, below at its base, they perceived a more sheltered situation; and why select that spot for their resting-place? There was no reason why they should not. Old Bill proposed it; there was no opposition offered by his young companions, and, without further parley, the four went floundering down the sloping side of the sand-hill, into the sheltered convexity at its base. On arriving at the bottom, they found themselves in the narrowest of ravines. The hillock from which they had descended was but the highest summit of a long ridge, trending in the same direction as the coast. Another ridge, of about equal height, ran parallel to this on the landward side. The bases of the two approached so near that their sloping sides formed an angle with each other. On account of the abrupt acclivity of both, this angle was almost acute, and the ravine between the two resembled a cavity out of which some great wedge had been cut, like a section taken from the side of a gigantic melon. It was in this re-entrant angle that the castaways found themselves, after descending the side of the dune, and where they had proposed spending the remainder of the night. They were somewhat disappointed on reaching their sleeping-quarters, and finding them so limited as to space. In the bottom of the ravine there was not breadth enough for a bed, even for the shortest of the party, supposing him desirous of sleeping in a horizontal position. There were not six feet of surface, nor even three, that could strictly be called horizontal. Even longitudinally, the bottom of the "gully" had a sloping inclination; for the ravine itself tended upwards until it became extinguished in the convergence of its inclosing ridges. On discovering the unexpected "strait" into which they had launched themselves, our adventurers were for a time nonplussed. They felt inclined to proceed farther in search of a "better bed", but their weariness outweighed this inclination; and, after some hesitation, they resolved to remain in the "ditch" into which they had so unwillingly descended. They proceeded therefore to encouch themselves.
