"The water below is rather poor," he informed Elaine, when he once more rejoined her above. "I believe I can reach a supply considerably better by building a bamboo platform that will give me access to a larger and fresher pool." Elaine was thinking of another, more personal danger. "Do you think these creatures have visited the cave?" "If they have, they left no signs." "You are not afraid they may go there soon--and discover the end of this passage?" Grenville shook his head. "I only wish they would try--every man Jack of them hunting there at once! If it weren't for this smoke, I should try to lure them in!" Glad of an occupation, no matter how forlorn the hope it afforded, he went promptly to work fetching all of the largest bamboo stems from his generous supply, together with wood for fuel and many lengths of creeper. By the time these various transfers were complete, he had left but little of their meager possessions in or about the former camp. Bombs, fuses, torch-wood, and much of his extra powder he now proceeded to store along the wall, and in a niche of the gallery, where they should neither obstruct the passage under foot, nor yet be exposed to possible accident from necessary fire. The terrace continued to be wrapped in smoke, as on the previous day. Instructing Elaine to call him instantly, should any attempt be made by the Dyaks to bridge the gap on the trail, he now began the laborious task of carrying one after another of the bamboo stems down the passage to the cave. The stems were large, some of them fully six inches through at the butt, and while they were never heavy, yet the twelve or more feet of length to which he had reduced them made their transfer through the narrow and angular gallery an awkward and troublesome maneuver, with only a torch for light. He had made up his mind that six of these stems, lashed together in pairs, or even laid side by side, and slightly separated, would complete a float on which he could readily find sufficient buoyancy for himself and a couple of water jugs, more especially as he thoroughly intended to stretch himself out flat, full length, upon it while moving about the shore. He felt, moreover, it must be so light he could not only launch it from the cave, but even withdraw it inside again, should danger so require. Fortunately, he reflected, none of the stems was split. Each comprised a set of water-tight compartments that a load of double his avoirdupois could hardly sink beneath the surface. If he found that four of the lengths would answer as well as six, he would certainly use no more. As he stumbled and edged his way downward once again, with the last of his load colliding here and there along the wall, he thought, perhaps, it might be possible to test the float in the salty pool that remained in the basin of the cavern. Could this be done, much time would be saved, and no risk of being discovered at his work need be incurred.
