Was there any chance of his getting out of it? Not by the dive, certainly. Without help that was impossible. He set himself to remember what his guide had said in reply to the questions with which he had been purposely plied. First, as to light. If Gu-gu was to be trusted the materials for this must be close at hand. Lance rose cautiously and felt about the ledge on which he lay and the walls of rock about him, and ere long came on what he sought. Flint and steel, a box of tinder, a bottle of oil, and a rag torch hung in an old bit of fishing-net to a peg that was driven into a crevice. So far, good; and after a minute these enabled him to see that he was in a sort of vaulted well, half hewn out of rock, half built in with brick. It was filled to some three feet or so with water, except in one corner, where the flooring shelved down to an archway. There it was deeper. This must be the opening of the tunnel through which they had dived, and through which, doubtless, Gu-gu had escaped; for he was not likely to have braved the intricate passages without a light. This thought made Lance look to see how much oil the bottle contained. There was only a mere driblet at the bottom. Plainly, therefore, he could pause no longer; so, instantly, without further thought, he waded across the pool and ran along the only passage which led from it. He had to stoop as he ran, and from the feel to his feet he guessed that the passage led upwards first, then downwards; apparently, too, in a perfectly straight line. The river, therefore, must be behind him, and he tried to make this point a fixed one, so as to give him some notion of his bearings. After a hundred yards or so he emerged into a second cave or chamber, also nearly waist-deep in water. From this several passages opened, some too small to admit of a man passing through them. These, then, must be the canals of which Gu-gu had spoken; one of them, possibly, that which should have supplied the Pool with Immortality. The memory of that crowd of eager, patient faces, disappointed by such a miserable trick, made Lance feel pitiful; then his pity brought a sudden practical suggestion. Why not open the sluice, or whatever it was, now, and give the miracle? It would at least keep _some_ of the crew quiet when it came, at dawn; the dawn which might be so fatal to quiet--the dawn which must, surely, be close at hand.
