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.

"I fear so."

"Very well, since the opportunity is lost, let us go on; it
