return to Granite House after having liberally supplied the stables.
As he was about to start, Harding asked him if he would not like one of them to accompany him, observing that the island was less safe than formerly. Ayrton replied that this was unnecessary, as he was enough for the work, and that besides he apprehended no danger. If anything occurred at the corral, or in the neighbourhood, he could instantly warn the colonists by sending a telegram to Granite House.
Ayrton departed at dawn on the 9th, taking the cart drawn by one onager, and two hours after, the electric wire announced that he had found all in order at the corral.
During these two days Harding busied himself in executing a project which would completely guard Granite House against any surprise. It was necessary to completely conceal the opening of the old outlet, which was already walled up and partly hidden under grass and plants, at the southern angle of Lake Grant. Nothing was easier, since if the level of the lake was raised two or three feet, the opening would be quite beneath it. Now, to raise this level they had only to establish a dam at the two openings made by the lake, and by which were fed Creek Glycerine and Falls River.
The colonists worked with a will, and the two dams, which besides did not exceed eight feet in width by three in height, were rapidly erected by means of well-cemented blocks of stone.
This work finished, it would have been impossible to guess that at that part of the lake, there existed a subterranean passage through which the overflow of the lake formerly escaped.
Of course the little stream which fed the reservoir of Granite House and worked the lift had been carefully preserved, and the water could not fail. The lift once raised, this sure and comfortable retreat would be safe from any surprise.
This work had been so quickly done, that Pencroft, Gideon Spilett, and Herbert found time to make an expedition to Port Balloon. The sailor was very anxious to know if the little creek in which the Bonadventure was moored, had been visited by the convicts.
“These gentlemen,” he observed, “landed on the south coast, and if they followed the shore, it is to be feared that they may have discovered the little harbour, and in that case, I wouldn’t give half-a-dollar for our Bonadventure.”
Pencroft’s apprehensions were not without foundation, and a visit to Port Balloon appeared to be very desirable. The sailor and his companions set off on the 10th of November, after dinner, well-armed. Pencroft, ostentatiously slipping two bullets into each barrel of his rifle, shook his head in a way which betokened nothing good to any one who approached too near to him, whether “man or beast,” as he said. Gideon Spilett and Herbert also took their guns, and about three o’clock all three left Granite House.
