"Well, perhaps he did intend to race me——"

"Does intend to race you is more like it," came shrewd interruption. "And there's your opportunity, Fitzrapp. With this notebook as concrete evidence, coupled with an affidavit from Ethel regarding the theft of the horses, there isn't a doubt that we can secure a warrant for his arrest. You can spring that document on him when he appears at the fair grounds to claim your thousand; have him held under prohibitive bail, and give the authorities time to work up a complete case against him."

"But if he doesn't appear at the track——" began Fitzrapp, as though lacking the older horseman's confidence.

"Then we must take up the hunt down in Montana," said MacDonald with eager assurance. "They'll never be able to disguise a horse like Canada, and with him it will not be a case of brand blotting. You'll probably find the stallion in the hands of some innocent purchaser, but we surely can trace back the transfers until we get the proof on the actual thieves. Against Duncan O'Hara, the ingrate, our case is already plain enough for us to ask the police to placard him through the border states. I'll suggest to Ethel that she offer a reward of five hundred dollars for his capture."

"Aren't we, perhaps, well rid of him without wasting Lady Ethel's money on rewards?"

The doughty major was stamping up and down the living-room, as well pleased with his plan of campaign as though personal loss was involved. "Well rid nothing! The guilty must pay. I'll go see if Ethel hasn't a snap-shot of the scamp that we can use on the posters."

Thomas Fitzrapp kept to his couch and wondered if Ethel Andress would be as keen as her fighting uncle to have the guilty pay. What a nuisance this man Childress was! The widow had refused to take the taunt about his success with Flame Gallegher and there was no being certain that she had not some secret understanding of her own with this unhandsome ranch enigma whose personality seemed to sweep ordinarily sensible women off their feet. Yes, the guilty must pay!

CHAPTER XXIV.
OUT OF THE NEST.

The days added themselves into several weeks at Crow's Nest, in the course of which Jack Childress improved upon the good impression which he had made the exciting afternoon of his entry. Delores had learned her lesson and caused him no further trouble, under strict orders from Crowe himself. Twice the branded man had left the outlaw resort for trips down into the State. No one asked him where he had gone or why. One of these departures was after Duncan O'Hara, already well known as a rustler who had won his spurs, had loped into the haven of the lawless. If he had been surprised to find Childress there, he managed to conceal the fact, and had accepted readily the stranger's invitation to share the individual hut which he had rented from Crowe.
