The air was frosty. During the night snow had fallen, and as Bucks followed his party the sun burst over the plain that they had crossed in the night and lighted the busy camp with a flood of gold. It was a camp such as few American boys had ever seen and of a type that no boy will ever see again. Everywhere along the cuts and hillsides and in sheltered spots the men had made temporary quarters by burrowing into the clay or soft rock and making dugouts and canvas-roofed huts, with earthen sides for walls. But not all were so enterprising as this. Some laborers were camping in old hogsheads. Even packing-boxes served others for shelter, but were all so disposed within the cuts and among the ridges of the railroad grade as to be safe from Indian forays. And along the completed railroad, all the way from the Missouri River, material and supply trains were moving to supply this noisy, helter-skelter camp, which seemed to Bucks all confusion, yet was in reality all energy. General Jack Casement, in charge, came forward to greet Stanley. "And they tell me, general," said Stanley, "you are laying a mile a day." "If you would give us the ties, colonel," returned Casement, short-bearded and energetic, "we should be laying two miles a day." "I have turned the Missouri River country upside down for timber," returned Stanley. "The trouble is to get the material forward over a single track so many hundred miles. However, we shall be getting ties down the Spider Water within two weeks. I am on my way up there now to see what the contractors are doing." It was the first intimation Bucks had had as to the object of the trip. Casement had a number of subjects to lay before his superior while within consulting distance, and Bob Scott, an hour later, announced that Stanley would not move on for two days. This left his attendants free, and when Scott, low-voiced and good-natured, asked Bucks if he wanted to go out on the Sweet Grass Plains with him after an antelope, Bucks accepted eagerly. The two saddled horses and Bucks, with a rifle borrowed from Sublette, followed Scott across a low-lying range of hills broken by huge stone crags and studded with wind-blown and stunted cedars, out upon the far-reaching expanse of an open plain. The scene was inspiring, but impressions crowded so fast one upon another that the boy from the Alleghanies could realize only that he was filled with sensations of delight as his wiry buckskin clattered furiously along the faint trail that carried him and his guide to the north and west. The sun was high when Scott reined up and, dismounting, tethered his horse in a glade hidden by a grove of aspens and bade Bucks do the same. "Getting hungry?" asked Scott, smiling at his companion. An answer was written pretty plainly on Bucks's face. "Didn't bring anything to eat, did you?" suggested Scott. Bucks looked blank. "I never thought of it," he exclaimed. "Did you bring anything?"
