On the 9th of October the bark canoe was entirely finished. Pencroft had kept his promise, and a light boat, the shell of which was joined together by the flexible twigs of the crejimba, had been constructed in five days. A seat in the stern, a second seat in the middle to preserve the equilibrium, a third seat in the bows, rowlocks for the two oars, a scull to steer with, completed the little craft, which was twelve feet long, and did not weigh more than two hundred pounds. The operation of launching it was extremely simple. The canoe was carried to the beach and laid on the sand before Granite House, and the rising tide floated it. Pencroft, who leaped in directly, maneuvered it with the scull and declared it to be just the thing for the purpose to which they wished to put it.

"Hurrah!" cried the sailor, who did not disdain to celebrate thus his own triumph. "With this we could go round--"

"The world?" asked Gideon Spilett.

"No, the island. Some stones for ballast, a mast and a sail, which the captain will make for us some day, and we shall go splendidly! Well, captain--and you, Mr. Spilett; and you, Herbert; and you, Neb--aren't you coming to try our new vessel? Come along! we must see if it will carry all five of us!"

This was certainly a trial which ought to be made. Pencroft soon brought the canoe to the shore by a narrow passage among the rocks, and it was agreed that they should make a trial of the boat that day by following the shore as far as the first point at which the rocks of the south ended.

As they embarked, Neb cried,--

"But your boat leaks rather, Pencroft."

"That's nothing, Neb," replied the sailor; "the wood will get seasoned. In two days there won't be a single leak, and our boat will have no more water in her than there is in the stomach of a drunkard. Jump in!"

They were soon all seated, and Pencroft shoved off. The weather was magnificent, the sea as calm as if its waters were contained within the narrow limits of a lake. Thus the boat could proceed with as much security as if it was ascending the tranquil current of the Mercy.

Neb took one of the oars, Herbert the other, and Pencroft remained in the stern in order to use the scull.

The sailor first crossed the channel, and steered close to the southern point of the islet. A light breeze blew from the south. No roughness was found either in the channel or the green sea. A long swell, which the canoe scarcely felt, as it was heavily laden, rolled regularly over the surface of the water. They pulled out about half a mile distant from the shore, that they might have a good view of Mount Franklin.

Pencroft afterwards returned towards the mouth of the river. The boat then skirted the shore, which, extending to the extreme point, hid all Tadorn's Fens.

This point, of which the distance was increased by the irregularity of the coast, was nearly three miles from the Mercy. The settlers resolved to go to its extremity, and only go beyond it as much as was necessary to take a rapid survey of the coast as far as Claw Cape.

The canoe followed the windings of the shore, avoiding the rocks which fringed it, and which the rising tide began to cover. The cliff gradually sloped away from the mouth of the river to the point. This was formed of granite reeks, capriciously distributed, very different from the cliff at Prospect Heights, and of an extremely wild aspect. It might have been said that an immense cartload of rocks had been emptied out there. There was no vegetation on this sharp promontory, which projected two miles from the forest, and it thus represented a giant's arm stretched out from a leafy sleeve.

The canoe, impelled by the two oars, advanced without difficulty. Gideon Spilett, pencil in one hand and notebook in the other, sketched the coast in bold strokes. Neb, Herbert, and Pencroft chatted, while examining this part of their domain, which was new to them, and, in proportion as the canoe proceeded towards the south, the two Mandible Capes appeared to move, and surround Union Bay more closely.

As to Cyrus Harding, he did not speak; he simply gazed, and by the mistrust which his look expressed, it appeared that he was examining some strange country.

In the meantime, after a voyage of three-quarters of an hour, the canoe reached the extremity of the point, and Pencroft was preparing to return, when Herbert, rising, pointed to a black object, saying,--

"What do I see down there on the beach?"

All eyes turned towards the point indicated.

"Why," said the reporter, "there is something. It looks like part of a wreck half buried in the sand."

"Ah!" cried Pencroft, "I see what it is!"

"What?" asked Neb.

"Barrels, barrels, which perhaps are full," replied the sailor.

"Pull to the shore, Pencroft!" said Cyrus.

A few strokes of the oar brought the canoe into a little creek, and its passengers leaped on shore.

Pencroft was not mistaken. Two barrels were there, half buried in the sand, but still firmly attached to a large chest, which, sustained by them, had floated to the moment when it stranded on the beach.

"There has been a wreck, then, in some part of the island," said Herbert.

"Evidently," replied Spilett.

"But what's in this chest?" cried Pencroft, with very natural impatience. "What's in this chest? It is shut up, and nothing to open it with! Well, perhaps a stone--"

And the sailor, raising a heavy block, was about to break in one of the sides of the chest, when the engineer arrested his hand.

"Pencroft," said he, "can you restrain your impatience for one hour only?"

But, captain, just think! Perhaps there is everything we want in there!"

"We shall find that out, Pencroft," replied the engineer; "but trust to me, and do not break the chest, which may be useful to us. We must convey it to Granite House, where we can open it easily, and without breaking it. It is quite prepared for a voyage; and since it has floated here, it may just as well float to the mouth of the river."

"You are right, captain, and I was wrong, as usual," replied the sailor.

The engineer's advice was good. In fact, the canoe probably would not have been able to contain the articles possibly enclosed in the chest, which doubtless was heavy, since two empty barrels were required to buoy it up. It was, therefore, much better to tow it to the beach at Granite House.

And now, whence had this chest come? That was the important question. Cyrus Harding and his companions looked attentively around them, and examined the shore for several hundred steps. No other articles or pieces of wreck could be found. Herbert and Neb climbed a high rock to survey the sea, but there was nothing in sight--neither a dismasted vessel nor a ship under sail.

However, there was no doubt that there had been a wreck. Perhaps this incident was connected with that of the bullet? Perhaps strangers had landed on another part of the island? Perhaps they were still there? But the thought which came naturally to the settlers was, that these strangers could not be Malay pirates, for the chest was evidently of American or European make.

All the party returned to the chest, which was of an unusually large size. It was made of oak wood, very carefully closed and covered with a thick hide, which was secured by copper nails. The two great barrels, hermetically sealed, but which sounded hollow and empty, were fastened to its sides by strong ropes, knotted with a skill which Pencroft directly pronounced sailors alone could exhibit. It appeared to be in a perfect state of preservation, which was explained by the fact that it had stranded on a sandy beach, and not among rocks. They had no doubt whatever, on examining it carefully, that it had not been long in the water, and that its arrival on this coast was recent. The water did not appear to have penetrated to the inside, and the articles which it contained were no doubt uninjured.

It was evident that this chest had been thrown overboard from some dismasted vessel driven towards the island, and that, in the hope that it would reach the land, where they might afterwards find it, the passengers had taken the precaution to buoy it up by means of this floating apparatus.

"We will tow this chest to Granite House," said the engineer, "where we can make an inventory of its contents; then, if we discover any of the survivors from the supposed wreck, we can return it to those to whom it belongs. If we find no one--"

"We will keep it for ourselves!" cried Pencroft. "But what in the world can there be in it?"

The sea was already approaching the chest, and the high tide would evidently float it. One of the ropes which fastened the barrels was partly unlashed and used as a cable to unite the floating a............
