Brooke would much rather have retired to sleep, but the man's earnestness had its effect on him, and he rose and went out into the rain with him. Allonby came near falling down the shaft when they stood at its head, but Brooke got him into the ore hoist and sent him down, after which he descended the running chain he had locked fast hand over hand. The level, as he had been told, was close to the surface, and while Allonby walked unsteadily in front of him with a blinking candle in his hat, they followed it into the face of the hill. Twice his companion stumbled over a piece of the timbering, and the light went out, while Brooke wondered uneasily if there was another sinking anywhere ahead as he lighted it again. He knew a little about mining, since he had on one or two occasions earned a few dollars assisting in the driving of an adit. Finally, Allonby stopped and leaned against the dripping rock, as he took off his hat and held the candle high above his head. Then he turned and pointed down the gallery the way they had come. "Look at it!" he said, thickly. "Until we struck the ore where you see the extra timbering, I counted the dollars every yard of it cost me as I would drops of my life's blood. I worked while the men slept, and lived like a Chinaman. There was a fortune within my grasp if those dollars would hold out until I reached it--and fortune meant England, and I once more the man I had been. Then--we came to that." He swung round and pointed with a wide, dramatic gesture which Brooke fancied he would not have used in his prosperous days, to a bare face of rock. It was of different nature to the sides of the tunnel, and had evidently come down from above. Brooke understood. The strata his companion had been working in had suddenly broken off and gone down, only he knew where. He sat down on a big fallen fragment, and there was silence for a space, emphasized by the drip of water in the blackness of the mine. Brooke was very drowsy, but the scene, with its loneliness and the haggard face of his companion showing pale and drawn in the candle-light, had a curious effect on him, and in the meanwhile compelled him to wakefulness. "You know where that broken strata has dipped to?" he said, at last. Allonby, who laughed in a strained fashion, sat down abruptly, and thrust a bundle of papers upon his companion. "Almost to a fathom. If you know anything of geology, look at these." Brooke, who unrolled the papers, knew enough to recognize that, even if his companion had illusions, they were the work of a clever man. There was skill and what appeared to be a high regard for minute accuracy in every line of the plans, while he fancied the attached calculations would have aroused a mathematician's appreciation. He spent several minutes poring over them with growing wonder, while Allonby held the candle, and then looked up at him. "They would, I think, almost satisfy any man, but there is a weak point," he said.
