Nothing therefore which threw any light on the supposed wreck could be found on this shore, yet an object of any importance, such as the hull of a ship, would have been seen directly, or any of her masts and spans would have been washed on shore, just as the chest had been, which was found twenty miles from here.  But there was nothing.

Towards three o’clock Harding and his companions arrived at a snug little creek.  It formed quite a natural harbor, invisible from the sea, and was entered by a narrow channel.

At the back of this creek some violent convulsion had torn up the rocky border, and a cutting, by a gentle slope, gave access to an upper plateau, which might be situated at least ten miles from Claw Cape, and consequently four miles in a straight line from Prospect Heights.  Gideon Spilett proposed to his companions that they should make a halt here.  They agreed readily, for their walk had sharpened their appetites; and although it was not their usual dinner-hour, no one refused to strengthen himself with a piece of venison.  This luncheon would sustain them until their supper, which they intended to take at Granite House.  In a few minutes the settlers, seated under a clump of fine sea-pines, were devouring the provisions which Neb produced from his bag.

This spot was raised from fifty to sixty feet above the level of the sea.  The view was very extensive, but beyond the cape it ended in Union Bay.  Neither the islet nor Prospect Heights was visible, and could not be from thence, for the rising ground and the curtain of trees closed the northern horizon.

It is useless to add that notwithstanding the wide extent of sea which the explorers could survey, and though the engineer swept the horizon with his glass, no vessel could be found.

The shore was of course examined with the same care from the edge of the water to the cliff, and nothing could be discovered even with the aid of the instrument.

“Well,” said Gideon Spilett, “it seems we must make up our minds to console ourselves with thinking that no one will come to dispute with us the possession of Lincoln Island!”

“But the bullet,” cried Herbert.  “That was not imaginary, I suppose!”

“Hang it, no!” exclaimed Pencroft, thinking of his absent tooth.

“Then what conclusion may be drawn?” asked the reporter.

“This,” replied the engineer, “that three months or more ago, a vessel, either voluntarily or not, came here.”

“What! then you admit, Cyrus, that she was swallowed up without leaving any trace?” cried the reporter.

“No, my dear Spilett; but you see that if it is certain that a human being set foot on the island, it appears no less certain that he has now left it.”

“Then, if I understand you right, captain,” said Herbert, “the vessel has left again?”

“Evidently.”

“And we have lost an opportunity to get back to our country?” said Neb.
