But there was not an hour to lose, for forty miles was a long march, and they could not hope to reach Granite House before night.

At six o'clock in the morning the little band set out. As a precaution the guns were loaded with ball, and Top, who led the van, received orders to beat about the edge of the forest.

From the extremity of the promontory which formed the tail of the peninsula the coast was rounded for a distance of five miles, which was rapidly passed over, without even the most minute investigations bringing to light the least trace of any old or recent landings; no debris, no mark of an encampment, no cinders of a fire, nor even a footprint!

From the point of the peninsula on which the settlers now were their gaze could extend along the southwest. Twenty-five miles off the coast terminated in the Claw Cape, which loomed dimly through the morning mists, and which, by the phenomenon of the mirage, appeared as if suspended between land and water.

Between the place occupied by the colonists and the other side of the immense bay, the shore was composed, first, of a tract of low land, bordered in the background by trees; then the shore became more irregular, projecting sharp points into the sea, and finally ended in the black rocks which, accumulated in picturesque disorder, formed Claw Cape.

Such was the development of this part of the island, which the settlers took in at a glance, while stopping for an instant.

"If a vessel ran in here," said Pencroft, "she would certainly be lost. Sandbanks and reefs everywhere! Bad quarters!"

"But at least something would be left of the ship," observed the reporter.

"There might be pieces of wood on the rocks, but nothing on the sands," replied the sailor.

"Why?"

"Because the sands are still more dangerous than the rocks, for they swallow up everything that is thrown on them. In a few days the hull of a ship of several hundred tons would disappear entirely in there!"

"So, Pencroft," asked the engineer, "if a ship has been wrecked on these banks, is it not astonishing that there is now no trace of her remaining?"

"No, captain, with the aid of time and tempest. However, it would be surprising, even in this case, that some of the masts or spars should not have been thrown on the beach, out of reach of the waves."

"Let us go on with our search, then," returned Cyrus Harding.

At one o'clock the colonists arrived at the other side of Washington Bay, they having now gone a distance of twenty miles.

They then halted for breakfast.

Here began the irregular coast, covered with lines of rocks and sandbanks. The long sea-swell could be seen breaking over the rocks in the bay, forming a foamy fringe. From this point to Claw Cape the beach was very narrow between the edge of the forest and the reefs.

Walking was now more difficult, on account of the numerous rocks which encumbered the beach. The granite cliff also gradually increased in height, and only the green tops of the trees which crowned it could be seen.

After half an hour's rest, the settlers resumed their journey, and not a spot among the rocks was left unexamined. Pencroft and Neb even rushed into the surf whenever any object attracted their attention. But they found nothing, some curious formations of the rocks having deceived them. They ascertained, however, that eatable shellfish abounded there, but these could not be of any great advantage to them until some easy means of communication had been established between the two banks of the Mercy, and until the means of transport had been perfected.

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.
