Allonby smiled in a curious fashion. "The one the rest split on? I see you understand." "You deduce where the ore ought to be--by analogy. That kind of reasoning is, I fancy, not greatly favored in this country by practical men. They prefer the fact that it is there established by the drill." Allonby made a little gesture of impatience. "They have driven shaft and adit for half a lifetime, most of them, and they do not know yet that one law of Nature--the sequence of cause and effect--is immutable. I have shown them the causes--but it would cost five thousand dollars to demonstrate the effect. Well, as no one will ever spend them, we will go back." He had come out unsteadily, but he went back more so still, as though a sustaining purpose had been taken from him, and, as he fell down now and then, Brooke had some difficulty in conveying him to the foot of the shaft. When he had bestowed him in the ore hoist, and was about to ascend by the chain, Allonby laughed. "You needn't be particularly careful. I shall come down here head-foremost one of these nights, and nobody will be any the worse off," he said. "I lost my last chance when that vein worked out." Then Brooke went up into the darkness, and with some difficulty hove his companion to the surface. They went back to the shanty together, and as Allonby incontinently fell asleep in his chair, Brooke retired to the bunk set apart for him. Still, tired as he was, it was some little time before he slept, for what he had seen had made its impression. The shanty was very still, save for the snapping of the fire, and the broken-down outcast, who held the key of a fortune the men of that province were too shrewd to believe in, slept uneasily, with head hung forward, in his chair. Brooke could see him dimly by the dying light of the fire, and felt very far from sure that it was a delusion he labored under. When he awakened next morning Allonby was already about, and looked at him curiously when he endeavored to reopen the subject. "It is not considerate to refer next morning to anything a man with my shortcomings may have said the night before," he said. "I think you should recognize that fact." "I'm sorry," said Brooke. "Still, it occurred to me that you believed very firmly in the truth of it." Allonby smiled drily. "Well," he said, "I do. What is that to you?" "Nothing," said Brooke. "I shall, as I think I told you, be worth about thirty dollars when the month is out. What is the name of the man Saxton wishes to sell the mine to?" "Devine," said Allonby, and went out to fling a vitriolic reproof at a miner who was doing something he did not approve of about the windlass, while Brooke, who saw no more of him, departed when he had made his breakfast.
