He stopped abruptly and stood staring vacantly in front of him, while Brooke heard him noisily draw in his breath.
"You can imagine what that meant!" he continued. "After what had happened in England I could never go back a poor man, but a good deal is forgiven the one who comes home rich. Then, while I tried to keep my head, we came to the fault where the ore vein suddenly ran out. It broke off as though cut through with a knife, and went down, as the men who knew no better said, to the centre of the earth. Now a fault is a very curious thing, but one can deduce a good deal when he has studied them, and a big snow-slide had laid bare an interesting slice of the foundations of this country in the valley opposite. It took me a month to construct my theory, and that was little when you consider the factors I had to reckon with – ages of crushing pressure, denudation by grinding ice and sliding snow, and Titanic upheavals thousands of years ago. The result was from one point of view contemptible. With about four thousand dollars I could strike the vein again."
"Of course you tried to raise them?"
Allonby made a grimace. "For six long years. The men who had lent me money laughed at me, and worked the poor ore back along the incline instead of boring. Somebody has been working it – for about five cents on the dollar – ever since, and when I told them what they were letting slip all of them smiled compassionately. I am of course – though once it was different – a broken man, with a brain clouded by whisky, only fit to run a played-out mine. How could I be expected to find any man a fortune?"
His brain, it was evident, was slightly affected by alcohol then, but there was no mistaking the genuineness of his bitterness. It was too deep to be maudlin or tinged with self-commiseration now. The little hopeless gesture of resignation he made was also very eloquent, and while the rain splashed upon the roof Brooke sat silent regarding him curiously. The dim light and the flickering radiance from the fire were still on one side of his face, forcing it up with all its gauntness of outline, but the weakness had gone out of it, and for once it was strong and almost stern. Then a little sardonic smile crept into it.
"A fortune under our feet – and nobody will have it! It is one of Fate's grim jests," he said. "I spent a month making a theory, and every day of six years – that is when I was capable of thinking – has shown me something to prove that theory right. Now Saxton wants to swindle another man into buying the mine for – you can call it a song."
He poured out another glass with a shaking hand, and then turned abruptly to his companion. "Put on your rubber coat and come with me," he said.
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.
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."
