By this time they had effected an entrance into the shed, the door of which was securely locked, while the boards of one entire side of the tumble-down structure swung in at a touch. The three men stood looking down the pitch black hole into which the rope disappeared. "Looks kind of pokey, doesn't it?" said Allery Jones. "Think you'd better try it, Fetherbee?" For answer, Mr. Fetherbee seized the lightly swinging rope with both hands, twisted one leg about it and slid gaily from sight. "_Bon voyage!_" called Dayton, down the inky shaft. "_Yage!_" came a hollow voice from the reverberating depths. They felt of the rope which was taut and firm. "He's all right," said Dayton. "There's not enough of him to get hurt," and he squeezed his portly person out between the flapping boards. "All the same, I shall be glad to see him again," Jones declared, with an anxious frown upon his usually _nonchalant_ countenance; and the two men started briskly down the hill in pursuit of "the team." Meanwhile, Mr. Fetherbee was making his way slowly and cautiously down the rope. It was a good stout one and he had no real misgivings. Yet the situation was unusual enough to have a piquant flavor. In the first place the darkness was more than inky in character, the kind of blackness in comparison with which the blackest night seems luminous. Then there was the peculiar quality of the air, so different from anything above ground, that the words chill, and dampness, had no special relation to it. In the strange, tomb-like silence, his own breath, his own movements, waked a ghostly, whispering echo which was extremely weird and suggestive. Mr. Fetherbee was enchanted. He felt that he was getting down into the mysterious heart of things; that he was having something which came within an ace of being an adventure. Then, as he felt his way down, farther and farther below the vain surface of things, that intervening ace vanished, and he came up against his adventure with a suddenness that sent a knife-like thrill to his heart. His foot had lost its hold of the rope; he was hanging by his hands only. Startled into what he condemned as an unreasoning agitation, he began describing a circle with his leg, searching for the lost rope. It must be there, of course; why, of course it must! He had certainly not gone more than fifty or sixty feet, and they had said something about three hundred feet? Where could the rope be? It must have got caught somehow on his coat! Or perhaps his right leg was getting numb and he could not feel anything with it. But no! His leg was all right. He felt out with his left leg. It did not even touch the wall of the shaft. There seemed to be nothing there, nothing at all! Nothing there? Nothing in all the universe, but this bit of rope he was clutching, and himself, a miserable little lump of quivering, straining nerves.
