Cyrus Harding wished to set out without delay; but as the expedition would be of some days' duration, it appeared best to load the cart with different materials and tools in order to facilitate the organization of the encampments. One of the onagers, however, having hurt its leg, could not be harnessed at present, and a few days' rest was necessary. The departure was, therefore, put off for a week, until the 20th of November. The month of November in this latitude corresponds to the month of May in the northern zones. It was, therefore, the fine season. The sun was entering the tropic of Capricorn, and gave the longest days in the year. The time was, therefore, very favorable for the expedition, which, if it did not accomplish its principal object, would at any rate be fruitful in discoveries, especially of natural productions, since Harding proposed to explore those dense forests of the Far West, which stretched to the extremity of the Serpentine Peninsula.
During the nine days which preceded their departure, it was agreed that the work on Prospect Heights should be finished off. Moreover, it was necessary for Ayrton to return to the corral, where the domesticated animals required his care. It was decided that he should spend two days there, and 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 neighborhood, he could instantly warn the colonists by sending a telegram to Granite House. Ayrton departed at dawn, 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 completely to 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
