Neb accompanied them to the turn of the Mercy, and after they had crossed, he raised the bridge. It was agreed that a gun-shot should announce the colonists’ return, and that at the signal Neb should return and re-establish the communication between the two banks of the river.

The little band advanced directly along the road which led to the southern coast of the island. This was only a distance of three miles and a half, but Gideon Spilett and his companions took two hours to traverse it. They examined all the border of the road, the thick forest, as well as Tabor Marsh. They found no trace of the fugitives who, no doubt, not having yet discovered the number of the colonists, or the means of defence which they had at their disposal, had gained the less accessible parts of the island.

Arrived at Port Balloon, Pencroft saw with extreme satisfaction that the Bonadventure was tranquilly floating in the narrow creek. However, Port Balloon was so well hidden amongst high rocks that it could scarcely be discovered either from the land or the sea.

“Come,” said Pencroft, “the blackguards have not been there yet. Long grass suits reptiles best, and evidently we shall find them in the Far West.”

“And it’s very lucky, for if they had found the Bonadventure,” added Herbert, “they would have gone off in her, and we should have been prevented from returning to Tabor Island.”

“Indeed,” remarked the reporter, “it will be important to take a document there which will make known the situation of Lincoln Island, and Ayrton’s new residence, in case the Scotch yacht returns to fetch him.”

“Well, the Bonadventure is always there, Mr Spilett,” answered the sailor. “She and her crew are ready to start at a moment’s notice!”

“I think, Pencroft, that that is a thing to be done after our exploration of the island is finished. It is possible after all that the stranger, if we manage to find him, may know as much about Tabor Island as about Lincoln Island. Do not forget that he is certainly the author of the document, and he may, perhaps, know how far we may count on the return of the yacht!”

“But!” exclaimed Pencroft, “who in the world can he be? The fellow knows us and we know nothing about him! If he is a simple castaway, why should he conceal himself? We are honest men, I suppose, and the society of honest men isn’t unpleasant to any one. Did he come here voluntarily? Can he leave the island if he likes? Is he here still? Will he remain any longer?”

Chatting thus, Pencroft, Gideon Spilett, and Herbert got on board and looked about the deck of the Bonadventure. All at once, the sailor having examined the bitts to which the cable of the anchor was secured—
