On turning their faces towards what they believed to be the land, there was no land in sight,--neither sand-hills, nor shore, nor even the narrow tongue upon whose tip they had been trusting themselves! There was nothing visible but water; and even this was scarce discernible at the distance of six paces from where they stood. They could only tell that water was around them, by hearing it hoarsely swishing on every side, and seeing through the dim obscurity the strings of white froth that floated on its broken surface. It was not altogether the darkness of the night that obscured their view; though this was of itself profound. It was a thick mist, or fog, that had arisen over the surface of the ocean, and which enveloped their bodies; so that, though standing almost close together, each appeared to the others like some huge spectral form at a distance! To remain where they were, was to be swallowed up by the sea. There could be no uncertainty about that; and therefore no one thought of staying a moment longer on the point of the sand-spit, now utterly submerged. But in what direction were they to go? That was the question that required to be solved before starting; and in the solution of which, perhaps, depended the safety of their lives. We need scarce say perhaps. Rather might we say, for certain. By taking a wrong direction they would be walking into the sea,--where they would soon get beyond their depth, and be in danger of drowning. This was all the more likely, that the wind had been increasing ever since they had laid down to rest, and was now blowing with considerable violence. Partly from this, and partly by the tidal influence, big waves had commenced rolling around them; so that, even in the shoal water where they stood, each successive swell was rising higher and higher against their bodies. There was no time to be lost. They must find the true direction for the shore, and follow it,--quickly too; or perish amid the breakers! CHAPTER V. A FALSE GUIDE. Which way to the shore? That was the question that arose to the lips of all. You may fancy it could have been easily answered. The direction of the wind and waves was landward. It was the sea-breeze, which at night, as every navigator is aware, blows habitually towards the land,--at least, in the region of the tropics, and more especially towards the hot Saaera. The tide itself might have told them the direction to take. It was the in-coming tide, and therefore swelling towards the beach. You may fancy that they had nothing to do but follow the waves, keeping the breeze upon their back.
