They felt that they would not be safe in leaving their place of concealment until the horde had re-crossed the ridge and descended once more into the oasis that contained their encampment. Making a rough calculation as to the time it would take for the return journey, and allowing a considerable margin against the eventuality of any unforeseen delay, the mids remained in their subaqueous retreat without any material change of position. When at length it appeared to them that the coast was clear, they rose to their feet and commenced wading towards the strand. Though no longer believing themselves observed, they proceeded silently and with caution, the only noise made among them being the chattering of their teeth, which were going like three complete sets of castanets. This they could not help. The night breeze playing upon the saturated garments, that clung coldly around their bodies, chilled them to the very bones; and not only their teeth, but their knees knocked together, as they staggered towards the beach. Just before reaching it, an incident arose that filled them with fresh forebodings. The strange beast that had threatened to intercept their retreat over the ridge, once more appeared before their eyes. It was either the same or one of the same kind, equally ugly, and, to all appearance, equally determined to dispute their passage. It was now patrolling the strand close by the water's edge; going backwards and forwards, precisely as it had done along the saddle-shaped sand-wreath; all the while keeping its hideous face turned towards them. With the moon behind their backs, they had a better view of it than before; but this, though enabling them to perceive that it was some strange quadruped, did not in any way improve their opinion of it. They could see that it was covered with a coat of long shaggy hair, of a brindled brown colour; and that from a pair of large orbs, set obliquely in its head, gleamed forth a fierce sullen light. How it had come there they knew not; but there it was. Judging from the experience of their former encounter with it they presumed it would again retreat at their approach; and, once more drawing their dirks, they advanced boldly towards it. They were not deceived. Long before they were near, the uncouth creature turned tail; and, again giving utterance to its unearthly cry, scampered off towards the ravine, in whose shadowy depths it soon disappeared from their view. Supposing they had nothing further to fear, our adventures stepped out upon the strand, and commenced consultation as to their future course. To keep on down the coast and get as far as possible from the Arab encampment was the thought of all three; and as they were unanimous in this, scarce a moment was wasted in coming to a determination. Once resolved, they faced southward; and started off as briskly as their shivering frames and saturated garments would allow them.
