The sea was rising over the ledge at the mouth, tossing and tumbling with foam-topped billows, and rolling up along the floor of the cavern in a seething mass of froth.

They saw how high it had come, and had no reason to fear that it would rise farther.

They now made their way to the spring, and drank heartily.

“We ought to be thankful that we are in so snug a place,” observed Bill; “but I tell you, we must take care not to eat up all our food in a hurry, or we may find it a hard matter to get more. The wind appears to have driven the sea over on this shore, and I doubt whether we shall be able to make our way along the beach even at low water.”

Jack did not at all like the idea of starving, but he saw that it would be wise to follow Bill’s advice.

They had food enough to last them for three days, as Jeannette had put up a double allowance; but the gale might blow much longer than that, and then what should they do?

“It’s no use troubling ourselves too much about the matter till the time comes,” observed Bill; “only we must be careful not to eat more than is necessary to keep body and soul together.”

As they had found a fire very useful and pleasant, they went down as close as they could venture to the water, and employed themselves in collecting all the driftwood and chips they could find. They agreed that they would do the same every day, so as to have a good stock of fuel. They wanted also to secure some pieces which might serve as torches, so that they could examine the smugglers’ store as they called it, which they had discovered.

They carried their wood and placed it on the soft warm sand, where it would dry more rapidly, for in its present state it would not serve to kindle a fire. They had, however, some dry pieces which would answer that purpose, and they judged rightly that they might place the damp wood on the top of their fire, when it would burn in time.

Most of the day was employed in this manner. Even after the tide went out they found a number of pieces washed up along the sides of the cavern. The seas, however, rolled so far up the beach that they were afraid of descending, or they might have obtained much more.
