Again the sound of the gun was heard, followed by a third report. All this time the cliffs above the further end of the harbour appeared crumbling away, while the ground where the marines’ huts stood, as well as beyond them, was heaving in visible undulations. Adair felt that at any moment the whole island might be convulsed in such a way as to destroy all remaining on it. He anxiously looked out for the return of Saint Maur and Roy. The movements increased in violence. He saw the men in the boat turning their eyes towards the cliff, as if they were eager to be away, fearing lest they themselves would be involved in the expected destruction of the island. He drew his breath more freely when at length he saw Saint Maur appear on the top of the path leading from the hill, followed by Roy and his men. Down they rushed at headlong speed. They had not a moment to lose; already huge rents appeared in the ground, some of a width across which it seemed scarcely possible they could leap, while the rocks on either side were tumbling and leaping along, and threatening to crush the party as they made their downward way.
Adair ordered the men in the gig to come in, and he stood half in the water holding her stem. He had no need to hurry Saint Maur and the rest. One poor fellow was struck, but his companions did not wait for him; they saw at a glance that he was killed. Another narrowly escaped, and a huge block came near Saint Maur as he sprang over a wide gap. With frantic haste they dashed along, and almost breathless reached the beach.
“Spring in!” cried Adair; “I shall be the last to leave the shore!”
Roy and the other men followed. Adair now jumped on board, and made his way to the stern sheets. The bow-men shoved, off without waiting for orders, and bending to their oars the gig was soon across the bar. Saint Maur and Roy were too much out of breath to speak. Indeed, Adair himself forgot to ask the reason of the signals they had heard; as, while steering for the bar, and casting a momentary glance over his shoulders, he saw the whole island rocking to and fro, and not only steam and smoke, but flames bursting forth from several fissures. Even now neither he nor his men were in safety: for should the island sink, the rafts and boats would be drawn into the vortex; or should it blow up, as seemed very likely, the fragments would too probably fall down and crush them, or create so violent a commotion of the ocean that they would scarcely escape being overwhelmed. Steering for the heaviest raft, he joined another boat in towing her. As yet they were under the lee of the island, and their sails were of no use. Long paddles had been formed for the use of the men on the rafts, who worked energetically, as the boats, heavily laden as they were, were unable to make much headway.
Roy, who had been hitherto panting too much to speak, now recovering himself, exclaimed—
“A sail, sir! a sail! We saw her standing towards the island. She’s a steamer, I think, though I could not make out her funnel. I caught sight of a wreath of white smoke hanging above her masthead.”
“Too probably she’s only passing,” said Adair.
“No, sir, she was standing steadily this way; and the heads of her courses had already risen above the horizon. We left the flag flying, so if the hill doesn’t come toppling down, she will see that, and know that there is some one on the rock. Perhaps she is coming expressly to look after us.”
“Thank Heaven!” cried Adair, in a voice choking with emotion, for the first time the calm composure he had hitherto exhibited giving way. “My poor people will be saved!”
The joyful news soon spread from boat to boat and raft to raft. At length feeling the wind, sail was set, and the little squadron steered a course as close to it as was possible, not to near the ship, but to get further off from the island. As soon as they had gained what Adair considered a safe distance, he ordered the first lieutenant, who was in one of the boats, to cast off and stand towards the stranger, whose topsails by that time could be seen. He had now only earnestly to pray that the weather would continue calm until they were all on board. Meantime he had cast many an anxious glance towards the land, which seemed, at the distance they were now from it, to be at rest, though the rumbling sounds which reached them and the thick clouds of smoke and flame ascending, showed them that they had good reason to be thankful that they had escaped it.
