"Would nothing tempt you to go on?" "I'm afraid not; that is--I--er--" the young man's embarrassment suddenly returned, and he stopped helplessly. Mrs. Burton's curiosity was instantly on the alert. "Then there _is_ something? Do tell me what it is," she pleaded. "It's nothing; in fact, it's much less than nothing. I hesitated because I--because your way of putting it is very--that is, it covers a great deal of ground," he stammered. "Don't make him quibble any more than he has to," said Burton, with mock severity. "You see it's quite impossible for him to tell the truth." The young man laughed good-naturedly. "That's the fact. I've been in the passenger service so long that I can't always be sure of recognizing the verities when I meet them. But to get back to the original sheep; I mustn't go on--not beyond Denver. It would have been better for all concerned if I had cut it short at the river." "For all concerned? for yourself and the invalids, you mean?" queried the curious one. "Yes, and perhaps for some others. But speaking of the invalids, I'll have to be getting back to them; they'll think I've deserted them. I'll be in again later in the day." Mrs. Burton waited until the swing-door of the vestibule had winged itself to rest behind him. Then she arched her eyebrows at her husband and said, "I wonder if Fred isn't the least little bit _épris_ with Gertrude Vennor?" To which the general agent replied, with proper masculine contumely, "I believe you would infer a whole railroad from a single cross-tie. Of course he isn't. Brockway is a good fellow, and a rising young man, but he knows his place." None the less it was the arrow of the woman's intuition, and not that of the man's reason, that pierced the truth. In the vestibule the passenger agent suddenly changed his mind about rejoining his party in the Tadmor, turning aside into the deserted smoking-room of the Ariadne to burn a reflective cigar, and to piece out reminiscence with present fact. Notwithstanding his expressed reluctance, he had intended going on to the Pacific Coast with the party in the Tadmor; had, in effect, more than half promised so to do. It was the time of year when he could best be spared from his district; and the members of the party had made a point of it. But the knowledge that Miss Gertrude Vennor was a passenger on the train opened up a new field wherein prudence and reawakened passion fought for the mastery, to the utter disregarding of the mere business point of view.
