"One understands that in Canada all natural commodities belong to the State, and any person discovering them can work them on certain terms," Challoner said. "It seems to follow that if your knowledge of the locality is worth anything, it must belong to you alone. How is it that nobody else suspects the belt contains oil?"

"A shrewd objection, but easily answered. The country in question is one of the most rugged tracts in Canada—difficult to get through in summer; in winter the man who enters it runs a serious risk. I'll admit that what you know about me is not likely to prejudice you in my favor; but, on your promise to keep it secret, I'll give you information that must convince you."

"Why don't you make your offer to some company floater or stockjobber?"

Clarke smiled in a pointed manner.

"Because I've a damaging record and no friends to vouch for me. I came here because I felt that I had some claim on you."

"You were mistaken," said Challoner curtly.

"Hear me out; try to consider my proposition on its merits. For a number of years, I've known the existence of the oil and have tried to prospect the country. It was difficult; to transport enough food and tools meant a costly expedition and the attracting of undesirable attention. I went alone, living with primitive Russian settlers and afterward with the Indians. To gain a hold on them, I studied the occult sciences, and learned tricks that impose upon the credulous. To the white men I'm a crank, to the Indians something of a magician; but my search for the oil has gone on; and now, while I already know where boring would be commercially profitable, I'm on the brink of tapping a remarkable flow."

"What will you do if it comes up to your expectations?" Challoner asked, for he had grown interested in spite of his disbelief in the man.

"Turn it over to a company strong enough to exact good terms from the American producers or, failing that, to work the wells. Then I'd go back to London, where, with money and the standing it would buy me, I'd take up my old profession. I believe I've kept abreast of medical progress and could still make my mark and reinstate myself. It has been my steadfast object ever since I became an outcast; I've schemed and cheated to gain it, besides risking my life often in desolate muskegs and the arctic frost. Now, I ask you to make it possible—and you cannot refuse."

Challoner was silent for a minute or two, while Clarke smoked impassively. The Colonel knew that he had a determined man to deal with, and he believed, moreover, that he had spoken the truth. Still, the fellow, although in some respects to be pitied, was obviously a dangerous rascal, embittered and robbed of all scruples by injustice. There was something malignant in his face that testified against him; but, worse than all, he had come there resolved to extort money as the price of his connivance in a wrong.
