Accordingly Lambert went down and waited 40 feet under water in the inky blackness for the inventor. Fluess made his way down the ladder in the centre of the shaft, taking a firm hold of the rungs with his hands and feeling for the next one with his foot. As it happened, the ladder was short of the bottom by some 10 feet, and they had forgotten to inform him of this fact. Fluess, coming to the end, felt as usual for the next rung. It was not there, so he lowered himself one rung by his hands, expecting to touch the bottom with his feet. His feet merely churned in the dank water, so he went down rung by rung until he was clinging to the last rung with his hands. After vainly feeling with his feet for the bottom, he let go his hold and dropped about 6 feet. Some boards creaked and tipped ominously under him as he landed, then he felt his way round until he came to Lambert. The diver took off the inventor’s life-line, and Fluess fared forth into those underground workings some 200 feet beneath the surface of the green fields above. It was a weird experience. At first he tried to walk, and being without any guide whatsoever he lost all sense of direction. Then he tried for the sides of the tunnel, but there were ditches and wreckage which brought him down so often that he was forced back to the centre of the road. So he went down on his hands and knees and began to crawl along, feeling the sleepers of the tram-track with his hands, using them as a guide. He came, after many tribulations, to a place where the sides and roof had fallen badly and very laboriously managed to crawl over the heap of debris. After struggling about the underground tunnel for an hour, he was forced at length to turn back. Another and yet another attempt he made, each time getting a little farther along the tunnel. “Why not let me try?” said Lambert at last. “Very well,” said the inventor. Lambert had never before used the new type of diving dress, but that did not deter him. He got into it and had a short trial dive one afternoon, and the next morning went down the shaft to try in dead earnest to close the sluice which was letting in the water. The inventor went down too, and sat there waiting, waiting, and wondering what had happened to Lambert, and whether the new diving dress was going to justify his hopes. The diver, meanwhile, was fighting his way forward over the numerous obstacles in the tunnel, crawling over the falls and squeezing between the roof and the debris. It was nervy, risky work, for he did not know whether another fall would come and bury him or close the small exit, nor did he know whether he could manage to find his way back again. Under such difficult conditions, anything is possible.
