Pulling himself up a little way to gain a securer footing, Colwyn took the coil of rope from his pocket, and selecting a strong withe which hung near him, sought to fasten the end of the rope to it. It took him some time to do this with the hand he had at liberty, but at length he accomplished it to his satisfaction, and then he allowed the coils of the rope to fall into the pit. He next essayed to test the strength of the support, by pulling at it. To his disappointment, his first vigorous tug snapped the withe to which the rope was attached. He tied the rope to a stronger growth, but with no better result: the growths seemed brittle, and incapable of bearing a great strain when tested separately. It was the twisted network of the withes and twigs which gave the climbing plants inside the pit sufficient toughness to support his weight. Taken singly, they had very little strength. Colwyn reluctantly realised that it would be folly to endeavour to attempt the further descent of the pit by their frail support, and he decided to relinquish the attempt. As he was about to ascend, the light of the torch brought into view that part of the pit to which he was clinging, and he noticed that the testing of the withes had torn away a portion of the leafy screen, revealing the black and slimy surface of the pit's side. Colwyn was amazed to see a small peg, with a fishing line attached to it, sticking in the bare earth thus exposed. Somebody had been down the pit and placed it there--recently, judging by the appearance of the peg, which was clean and newly cut. What was at the other end of the line, which dangled in the darkness of the pit? A better hiding place for anything valuable could not have been devised. The thin fishing line was indiscernible against the slimy side of the pit, and Colwyn realised that he would never have discovered it had it not been for the lucky accident which had exposed the peg to which the line was anchored. A place of concealment chosen at the expense of so much trouble and risk indicated something well worth concealing, and it was with a strong premonition of what was suspended down the pit that the detective, taking a firmer hold of the twining tendrils above his head, began to haul up the line. The weight at the end was slight; the line came up readily enough, foot after foot running through his hand, and then, finally, a small oblong packet, firmly fastened and knotted to the end of the line. Colwyn examined the packet by the light of the torch. It was a man's pocket-book of black morocco leather, a large and serviceable article, thick and heavy. The detective did not need the information conveyed by the initials "R. G." stamped in silver lettering on one side, to enlighten him as to the owner of the pocket-book and what it contained.
