"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!" * * * * * II. 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 south-westerly 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 "stocked" 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
