How rapidly we have grown! What was once but dreams of the future first changed to reality, and then sank away until now they are but dreams of the past. No more the long train of dust-covered wagons, drawn by the slow and patient oxen, winds across the level plains or passes through the deep defile. No more the Pony Express or the lumbering stage-coach bring the quickest word or forms the fastest transport between the inter-mountain region and "The States." How hard it is to understand the briefness of time that has passed since this great interior country was practically a howling wilderness, inhabited by bands of savage Indians and penetrated only by intrepid trappers or hunters! As we are now whirled along over the Laramie Plains, the Humboldt Desert, or through the Echo or Weber Canons, reclining on luxuriously cushioned seats, and but a few hours away from the Atlantic or Pacific seaboards, we can scarcely realize it. Surely the locomotive plays a wondrous part in the destiny of modern nations. Without its aid the country through which we are about to pass might have become as was surmised by Irving, the cradle of a race inimical to the higher civilization to the East and West. Now we behold it a land giving promise of future greatness, where peace, wealth and happiness shall go hand in hand, and where already it is well-nigh impossible for the youth of today to fully comprehend the struggles and privations of its pioneer fathers. The sketches, the greater number, are roughly made. There was little time to loiter by the wayside. Some of them are hardly more than hasty outlines, filled in, perhaps, when the camping-ground was reached. Some show an impression dashed off of a morning or evening, or, sometimes, of a noonday. Once in a while there is a subject more carefully finished, telling of an early camp or of a half-day's rest. Some are in white and black merely, others in color. What a new delight it was to one young and city-bred, to mingle in the freedom of camp life such as we enjoyed near that spot. How sweet it was to pass the days and nights under the blue canopy of heaven! Three weeks we remained there; three weeks elapsed ere our train was ready to start. There was nothing very beautiful, it may be, in the scenery bordering upon "The Mad Waters," but it was wild and sylvan at the time, and we were excited by the prospect of those months of travel that lay before us.
