A dull rage came over him and when he roused up next morning that fixed idea was still in his brain. But in the morning it was different. Those two personalities that had been so exalted, and differentiated, by drink, snapped back into one substantial I Am; and his tumultuous, fighting ego took command. Rimrock rose up thinking and the first hour after breakfast found him working feverishly to build up a defense. He had been jumped once before by Andrew McBain--it must not happen again. No technicality must be left to serve as a handle for this lawyer-robber to seize. Before noon that day Rimrock had two gangs of surveyors on their way to his Tecolote claims; and for a full week they labored, running side-lines, erecting monuments and taking angles on every landmark for miles. The final blue-prints, duly certified and witnessed, he took to the Recorder himself and then, still obsessed by his premonition of evil, he came back to serve notice on McBain. For every man there is always some person instinctively associated with trouble; some person that he hates beyond all bounds and reason, and intuitively fears and distrusts. In the jumping of the Gunsight there had been others just as active, but Rimrock had forgiven them all but McBain. Even the piratical L. W., for all his treachery, was still within the pale of his friendship. But this tall, lanky Scotchman, always lurking within the law as a spider hides for safety in its hole, invoked nothing but his anger and contempt. Rimrock dropped off the train that had brought him from the County seat, and went straight up the street to the hotel. McBain was in his office, stalking nervously up and down as he dictated to Mary Fortune, when the door opened suddenly and Rimrock Jones stepped in and stood gazing at him insolently. "Good morning," he said with affected nicety of speech. "I hope that I don't intrude. Yes, it is lovely weather, but I came here on a matter of business. We've had our difficulties, Mr. Apex McBain, but all that is in the past. What I came to say is: I've got my eye on you and I don't want you out at my mine. Those claims are my property and, I give you fair notice, if you trespass on my ground you'll get shot. That's all for the present; but, because you've cleaned me once, don't think you can do it again." He bowed with mock politeness, taking off his hat with a flourish, and as he backed out Mary Fortune turned pale. There was something in that bow and the affected accents that referred indirectly to her. She knew it intuitively and the hot blood rushed back and mantled her cheeks with red. Then she straightened up proudly and when McBain began to dictate her machine went on clacking defiantly.
