The young operator, who, in spite of his efforts to conceal his hurt, now limped a little as he walked up the street of the new railroad town might well look with curiosity and amazement on what he saw. The street he walked in was no more than a long assemblage of saloons, restaurants, boarding-houses, gambling-houses, dance-halls and shops. Nearer the station and fronting on the open square, there were barber-shops and so-called hotels. Up and down the side streets he saw livery-stables and roughly built warehouses for contractors' supplies, army supplies, and stage-line depots. The main street was alive with strange-looking frontiersmen, trappers, hunters, scouts, soldiers, settlers, railroad laborers, outlaws, prospectors, and miners. Every face that Bucks looked into presented a study. They were sometimes faces bronzed with the clear, dry sunshine of the plains and mountains, rugged with adventure and keen with dangers met and passed, but others were furrowed with dissipation and seamed with vice, or merely vacant with the curiosity of the wanderer. Nearly every man carried a fire-arm of some sort. Indians were a continual menace upon the frontier to the north and west and on the front where the road was being built; and in the train-service and construction work railroad men usually went armed. Moreover, when the frontiersmen were not arming against the Indians they were arming against one another; it being difficult at times to tell whether the white men or the savages were the more dangerous to the peaceful pursuit of happiness. As Bucks, returning down Front Street, neared the square that opened before the station a group of army officers were walking across it. They were the first regular officers he had ever seen and he regarded them with interest. At the station the chief despatcher, Baxter, met him at the door. "Bucks, I've been waiting for you. Can you ride a horse?" Bucks smiled. "Colonel Stanley," continued Baxter, "is going to the front to-night. He wants to take an operator with him. Giddings isn't well enough to go, but he can take your key to-night; you can go with the colonel instead. He will take Dancing and a detail of cavalrymen with Leon Sublette and Bob Scott for guides." The suddenness of the call was not unpleasant. It was such continual excitement and new adventure that Bucks liked and he said he was ready. The despatcher told him to hunt up Bill Dancing, who would give him the details. Within an hour the cavalry horses were being loaded into a box-car up at the stock chute, and while Bucks and big Bill Dancing watched them an engine and the chief engineer's car were backed down the yard to make up the special train. At the same moment, the two saw Stanley walking across the yard with two engineers who were going to the front with him.
