feather of her little bonnet, matching the gray traveling dress, to the tips of her dainty boots; and one, too, at whom old Fifth Avenue promenaders would have turned to look. She had a charming figure, brown hair, hazel eyes, and an expression at once kind, intelligent, and spirited. She had cheerfully left a luxurious home to follow the young engineer's fortunes; and it was well known that those fortunes had been materially advanced by her tact and cleverness.

The third passenger in question had just been in conversation with Sinclair and the latter was telling his wife of their curious meeting. Entering the toilet-room at the rear of the car, he said, he had begun his ablutions by the side of another man, and it was as they were sluicing their faces with water that he heard the cry:

"Why, Major, is that you? Just to think of meeting you here!"

A man of about twenty-eight years of age, slight, muscular, wiry, had seized his wet hand and was wringing it. He had black eyes, keen and bright, swarthy complexion, black hair and mustache. A keen observer might have seen about him some signs of a jeunesse orageuse, but his manner was frank and pleasing. Sinclair looked him in the face, puzzled for a moment.

"Don't you remember Foster?" asked the man.

"Of course I do," replied Sinclair. "For a moment I could not place you. Where have you been and what have you been doing?"

"Oh," replied Foster, laughing, "I've braced up and turned over a new leaf. I'm a respectable member of society, have a place in the express company, and am going to Denver to take charge."

"I am very glad to hear it, and you must tell me your story when we have had our breakfast."

The pretty young woman was just about to ask who Foster was, when the speed of the train slackened, and the brakeman opened the door of the car and cried out in stentorian tones:

"Pawnee Junction; twenty minutes for refreshments!"

When the celebrated Rocky Mountain gold excitement broke out, more than twenty years ago, and people painted "Pike's Peak or Bust" on the canvas covers of their wagons and started for the diggings, they established a "trail" or "trace" leading in a southwesterly direction from the old one to California.

At a certain point on this trail a frontiersman named Barker built a forlorn ranch-house and corral, and offered what is conventionally called "entertainment for man and beast."

For years he lived there, dividing his time between fighting the Indians and feeding the passing emigrants and their stock. Then the first railroad to Denver was built, taking another route from the Missouri, and Barker's occupation was gone. He retired with his gains to St. Louis and lived in comfort.

Years passed on, and the "extension" over which our train is to pass was planned. The old pioneers were excellent natural engineers and their successors could find no better route than they had chosen. Thus it was that "Barker's" became, during the construction period, an important point, and the frontiersman's name came to figure on time-tables. Meanwhile the place passed through a process of evolution which would have delighted Darwin. In the party of engineers which first camped there was Sinclair, and it was by his advice that the contractors selected it for division headquarters. Then came drinking "saloons" and gambling houses—alike the inevitable concomitant and the bane of Western settlements; then scattered houses and shops and a shabby so-called hotel, in which the letting of miserable rooms (divided from each other by canvas partitions) was wholly subordinated to the business of the bar. Before long, Barker's had acquired a worse reputation than even other towns of its type, the abnormal and uncanny aggregations of squalor and vice which dotted the plains in those days; and it was at its worst when Sinclair returned thither and took up his quarters in the engineers' building. The passion for gambling was raging, and to pander thereto were collected as choice a lot of desperadoes as ever "stacked" cards or loaded dice. It came to be noticed that they were on excellent terms with a man called "Jeff" Johnson, who was lessee of the hotel; and to be suspected that said Johnson, in local parlance, "stood in with" them. With this man had come to Barker's his daughter Sarah, commonly known as "Sally," a handsome girl, with a straight, lithe figure, fine features, reddish auburn hair, and dark-blue eyes. It is but fair to say that even the "toughs" of a place like Barker's show some respect for the other sex, and Miss Sally's case was no exception to the rule. The male population admired her; they said she "put on heaps of style"; but none of them had seemed to make any progress in her good graces.

On a pleasant afternoon just after the track had been laid some miles west of Barker's, and construction trains were running with some regularity to and from the end thereof, Sinclair sat on the rude veranda of the engineers' quarters, smoking his well-colored meerschaum and looking at the sunset. The atmosphere had been so clear during the day that glimpses were had of Long's and Pike's peaks, and as the young engineer gazed at the gorgeous cloud display he was thinking of the miners' quaint and pathetic idea that the dead "go over the Range."

"Nice-looking, ain't it, Major?" asked a voice at his elbow, and he turned to see one of the contractors' officials taking a seat near him.

"More than nice-looking to my mind, Sam," he replied. "What is the news to-day?"

"Nothin' much. There's a sight of talk about the doin's of them faro an' keno sharps. The boys is gettin' kind o' riled, fur they allow the game ain't on the square wuth a cent. Some of 'em down to the tie-camp wuz a-talkin' about a vigilance committee, an' I wouldn't be surprised ef they meant business. Hev yer heard about the young feller that come in a week ago from Laramie an' set up a new faro-bank?"

"No. What about him?"

"Wa'al, yer see he's a feller thet's got a lot of sand an' ain't afeard of nobody, an' he's allowed to hev the deal to his place on the square every time. Accordin' to my idee, gamblin's about the wust racket a feller kin work, but it takes all sorts of men to make a world, an' ef the boys is bound to hev a game, I calkilate they'd like to patronize his bank. Thet's made the old crowd mighty mad an' they're a-talkin' about puttin' up a job of cheatin' on him an' then stringin' him up. Besides, I kind o' think there's some cussed jealousy on another lay as comes in. Yer see the young feller—Cyrus Foster's his name—is sweet on thet gal of Jeff Johnson's. Jeff was to Laramie before he come here, an' Foster knowed Sally up thar. I allow he moved here to see her. Hello! Ef thar they ain't a-coming now."

Down a path leading from the town past the railroad buildings, and well on the prairie, Sinclair saw the girl walking with the "young feller." He was talking earnestly to her and her eyes were cast down. She looked pretty and, in a way, graceful; and there was in her attire a noticeable attempt at neatness, and a faint reminiscence of bygone fashions. A smile came to Sinclair's lips as he thought of a couple walking up Fifth Avenue during his leave of absence not many months before, and of a letter many times read, lying at that moment in his breast-pocket.

"Papa's bark is worse than his bite," ran one of its sentences. "Of course he does not like the idea of my leaving him and going away to such dreadful and remote places as Denver and Omaha and I don't know what else; but he will not oppose me in the end, and when you come on again—"

"By thunder!" exclaimed Sam; "ef thar ain't one of them cussed sharps a-watchin' 'em."

Sure enough a rough-looking fellow, his hat pulled over his eyes, half concealed behind a pile of lumber, was casting a sinister glance toward the pair.

"The gal's well enough," continued Sam; "but
