Here the overland stages took their departure for the distant mining town of Denver, and here the long trains of great freight-wagons were loaded for their toilsome journey over the Santa Fé trail to the far-away valley of the Rio Grande. Here, on side-tracks, were the construction-cars, movable houses on wheels, in which lived the graders, track-layers, and other members of the army of workmen employed in the building of a railroad. Railroad men, soldiers, teamsters, traders, Indians, and Mexicans, horses, mules, and oxen mingled here in picturesque confusion. Nearly every man carried a rifle, and it was rare to meet one who did not wear one or more revolvers strapped to his waist.
