Whether or not the volcano would accede to his request seemed very doubtful. Towards morning the commotions increased, crash succeeded crash, and they could perceive that other portions of the cliff had given way, while there was some fear that the rafts would be swamped by the sea which the falling masses created, before they could get out of the harbour. Strange to say, in spite of the fearful danger in which they were placed, the men joked as much as ever, though they worked away in a manner which showed that they were fully conscious of the necessity of speed, the officers labouring with them as hard as any one. At the sound of the boatswain’s call they scampered off to breakfast, which they bolted in a few minutes, and soon came back to their work.

The weather now became finer than it had been since they had landed on the island many months before. The sky was clear and the air pure, and there was not an invalid among them.

The sixth raft had just been completed, and the men were working it down to the water, when a rumbling sound far louder than any thunder was heard. The tall cliffs appeared as if about to fall down and fill up the whole of the harbour, the mouth evidently of an ancient crater. The rocks were seen to lift and heave; Adair stood on the shore, superintending the launching of the raft, apparently as cool and unmoved as ever.

“Now, my lads, get the boats into the water,” he exclaimed. “Let their proper crews attend to them; the rest of you assist the marines in bringing down the provisions and water.”

It should have been said that, under the direction of the pay-master and his assistants, all the casks had been filled with water, and all the provisions done up in packages, which could be easily transported.

Even at that moment perfect discipline prevailed; the men hurried backwards and forwards, it is true, as fast as their legs could carry them. They worked like a colony of ants, knowing exactly what they had to do. The midshipmen were ordered into the boats with their respective crews to stow the packages, and to keep the rafts off the beach. These were next loaded, and the boats being filled, the men were ordered to take their places on the rafts.

Captain Adair and Lord Saint Maur stood alone on the shore, when the sound of a gun was heard.

“I forgot Roy and the men with him,” exclaimed Adair.

“I’ll go for him,” cried Desmond, and before he could be stopped, he darted off.

Adair now ordered the boats to take the rafts in tow, and to proceed over the bar, as it would be impossible to find a more favourable opportunity for crossing it. One boat—his own gig—with four hands in her, only remained, so that she was able to carry, in addition, Roy and his party.
