Even while Bob had the possibility in his mind, he saw, clearly defined on the sky-line on the farther side of the valley, a small band of mounted men approaching at a walking pace. The group was too small to be of any avail as a reinforcement, and Bob was wondering who the new-comers could be, when, as they drew nearer, he noticed among them one man on foot, walking with a strangely awkward gait. Intently watching him, he had in a few moments the explanation of his awkwardness: he had his arms tied behind him. Evidently he was a prisoner—some luckless Japanese scout or spy, perhaps, who had fallen into the hands of a Russian patrol, and was now being marched off for summary trial. Bob compared his own case with that of the Japanese, almost to the advantage of the latter, and watched him with mixed feelings until the edge of the hill hid him from sight. Glancing down, he saw the dead bear still jammed between the rocks; but there was a change in its appearance. Pieces of its fur had been torn away; apparently it had been mauled by some prowling beast of prey. Bob shuddered as he realized what a fate he had himself escaped—when suddenly a thought came to him. The bear had fallen headlong down the precipice. Was it possible that he himself might make a safe and leisurely descent, and, under cover of night, reconnoitre the Russian position? At the back of his mind there was a dim outline of an idea that brought a flush to his cheeks and a light into his eyes. He turned sharp round, hurried through the cavern, and, stopping only to answer a remark from Mrs. Pottle, sought his faithful Chinaman, Ah-Sam. During the next hour the two were busily engaged at a secluded part of the gully, making the traces from the mule-cart into a long knotted rope, with three loops at intervals, formed of the collars of the animals. There was not enough to construct a ladder, but Bob hoped the rope would prove long enough to let him down from the mouth of the cavern on to the slope, whence the descent to level ground would be easy. When it was complete, he took the only shaft of the cart which had not been demolished for fuel, returned to the cavern, and, evading Mrs. Pottle’s eager questions, went quickly with Ah-Sam to the farther end. At the point where the cleft narrowed just before opening out on the hill-face they placed the shaft across from side to side, and then firmly attached the rope to it. It was not safe to do anything more in the daylight. During the afternoon Bob at last yielded to Mrs. Pottle’s entreaties, and related the story of his adventures up to his meeting with her. "It just beats anything!" exclaimed the lady at its conclusion. "Why, Ethel, what a story it would make!" "I don’t think of that, auntie." "Well, why not? My pen is rusting for want of work. What do you think, then?"
