Mackenzie flung him a disgusted look. “We don’t go much on heroes out here. He’s game, if that’s what you mean. And able, too. Bucky O’Connor himself isn’t any smarter at following a trail.”

“And who is Bucky O’Connor?”

“He’s the man that just ran down Fernendez. Think I’ll have a smoke, sir. Care to join me?”

But the Pekin-Bostonian preferred to stay and jot down in his note-book the story of the bear-trap, to be used later as a sermon illustration. This may have been the reason he did not catch the quick look that passed without the slightest flicker of the eyelids between Major Mackenzie and the young woman in Section 3. It was as if the old officer had wired her a message in some code the cipher of which was known only to them.

But the sheriff, returning at the head of his cohorts, caught it, and wondered what meaning might lie back of that swift glance. Major Mackenzie and this dark-eyed beauty posed before others as strangers, yet between them lay some freemasonry of understanding to which he had not the key.

Collins did not know that the aloofness in the eyes of Miss Wainwright—he had seen the name on her suit-case—gave way to horror when her glance fell on his gloved hand. She had a swift, shuddering vision of a grim-faced man, jaws set like a vise, hacking at his wrist with a hunting-knife. But the engaging impudence of his eye, the rollicking laughter in his voice, shut out the picture instantly.

The young man resumed his seat, and Miss Wainwright her listless inspection of the flying stretches of brown desert. Dusk was beginning to fall, and the porter presently lit the lamps. Collins bought a magazine from the newsboy and relapsed into it, but before he was well adjusted to reading the Limited pounded to a second unscheduled halt.

Instantly the magazine was thrown aside and Collins’ curly head thrust out of the window. Presently the head reappeared, simultaneously with the crack of a revolver, the first of a detonating fusillade.

“Another of your impatient citizens eager to utilize the unspeakable convenience of rapid transit,” suggested the clergyman, with ponderous jocosity.

“No, sir; nothing so illegal,” smiled the cattleman, a whimsical light in his daredevil eyes. He leaned forward and whispered a word to the little girl in front of him, who at once led her younger brother back to his section.
