As he spoke, a low dull sound was heard coming from the shore, and from the top of the volcano rose a dense black mass, which extended itself like an umbrella. Directly afterwards down came a shower of ashes, covering every part of the boat, while the coast itself was completely shut out from view, except where a lurid glare could be seen on the summit of the hill, and from the streams of lava descending the sides. Masses of rock and other dense substances were also thrown up, and their splashes could be heard as they fell into the water, though they themselves were invisible. Lord Reginald steered to the northward, in order that they might as soon as possible get away from the dangerous neighbourhood, but it was some time before they were free of the ashes and once more had the bright sun shining down upon them. They looked anxiously towards the island, and were thankful to observe that a large portion to the eastward was bright and fair, showing that it had not suffered materially from the eruption. It might, however, only be the commencement of a still more serious outbreak, and they were thankful that they had their vessel ready, in case it should become necessary to escape for their lives. As they opened up the eastern side of the hill, they saw the trees which had hitherto escaped, burning furiously, surrounded by the hot lava. They had too much reason to fear that the conflagration might extend still further, and destroy the whole of the remaining vegetation, though it was possible that the stream would stop its progress, and that the part of the island on which they had been living might be spared. Dick now set to work to get rid of the ashes which covered the boat. It was no easy task. He had only a piece of board to serve as a shovel, and a handful of oakum. He cleared the decks and water-ways and thwarts, but he found it impossible to get them out of the bottom of the boat. "Never mind," said Lord Reginald, "it will serve instead of a coat of paint." "She will look very like a coal barge," answered Dick, who was vain of the hitherto clean appearance of their craft. The wind continued very light, and it was some time before they reached the eastern end of the island, which they calculated was at the utmost ten miles long and five or six broad. They looked out narrowly for any small harbour into which they might run, should the wind come from the southward, and blow into their bay.
