These men and their devoted band of followers were the first to break into the world-old solitudes of the heart of the continent and to explore the mountain fastnesses in which the mighty Columbia has its birth.
Following in their footsteps, the hardy American emigrant, trader, adventurer, and home-seeker penetrated the wilderness, and, building better than they knew, laid the foundations of populous and thriving States.

Peaceful farms and noble cities, towns and villages, thrilling with the hum of modern industry and activity, are spread over the vast spaces through which the explorers threaded their toilsome trail, amid incredible privations and hardships, showing the way westward across the boundless continent which is ours.

Let the names of those two men long be held in grateful honor by the American people! INDEX A Alkali, natural deposits of, 60.
