It was almost too much to credit, this apparent retreat of the fiends so bent upon his capture. He made no positive report to Elaine of the fact he felt he must verify, lest he find himself obliged to retract it later. She had quickly responded to his ministrations, having fainted as much from lack of food and rest as from shock in that final moment. Concerning the final effect of her shot, she was destined never to know. Grenville was far too wise to let her believe she had taken the life even of a fiend in human semblance. He told her the Dyaks had fled from the place, which flight he had personally witnessed. He was certain, moreover, they would hardly return again that day, if they did not quit the island. Assured of the safety of the adventure, he descended to the jungle and returned with an armful of fruit. He proceeded later to the spring for a fresh supply of water. Estimating the final fighting force of the Dyaks at ten, and conceding that five, at the least, must have perished at the cave, since one or two must have guarded the boats while three were searching the chamber, he concluded that no more than four at the most could still remain uninjured. He had gone to the edge of the ruin, above the obliterated cave, and, having discovered no boat either near or far, had arrived at a fairly accurate conjecture respecting the fate of the craft the Dyaks had employed. One more calculation, respecting the number of able seamen required to navigate the retreating vessels, convinced him the island was deserted to the uses of Elaine and himself. It was not, however, till that afternoon that he cautiously explored their former possessions and confirmed the hope in his breast. There was ample evidence about the spring, and in the jungle, of the methods of living the Dyaks had employed, but neither at the western inlet, back of the central hill of rock, nor at the friendly estuary, was anything boatlike to be found. His catamaran had vanished, along with the larger craft, and its fate he could readily surmise. He lost no time in arranging a number of his snares and traps for the meat of which they were in need. Their camp was made as before on the terrace proper, despite the heat of the sun. It was not until many of these essential comforts had been once more established that Sidney explored the gallery to determine what destruction had been wrought by his double mine. Everything stored in the lower depths had been hopelessly buried by the rock. The passage was open for no more than half its former length. His bamboo raft was among the possessions sacrificed to the ruse that had finally succeeded beyond even his wildest dreams. Not ten feet back of his basket-load of treasure the last of the caving had been halted.
