Pike's expeditions were the first military and the second governmental explorations which were pushed to any considerable extent in our then newly acquired territory of Louisiana. The name and fame of the brilliant young soldier who impersonated the authority of the United States over all the ground between British and Spanish possessions are thus inseparably linked with those of Lewis and Clark in the beginning of our history of the Great West--a West so great that it reached from the Mississippi to the Pacific. The two movements were similar in scope and plan; both were in the nature of claiming possession of property; they were alike fruitful of permanent good results; but they differed entirely in the circumstances under which each was devised, and to a marked degree in their respective purposes. Lewis and Clark's enterprise originated with the President of the United States; and though both of the men to whom that most memorable exploration was confided were officers of the regular army, their military organization was entirely subservient to affairs of state, being simply designed to secure the most efficient discipline in the discharge of certain civilian duties. Jefferson had invested heavily in real estate; the Louisiana purchase had been made with the people's money; he naturally wished to know what sort of a bargain he had made with Napoleon; so he sent Lewis and Clark to explore the vast extent of country he had bought. While their faces were still fixed on the setting sun, which for them still dipped behind the shining snow-caps, Pike set forth on his first journey northward; while they were homeward bound from the South Sea by way of the mighty Missouri and the rugged Roche Jaune, he was pressing on his second way toward the Mexican mountains. Both his expeditions originated with the commander-in-chief of the army; both were as strictly military in method as in purpose. Pike was the simon-pure and simple soldier, who had been ordered by his general to carry our flag among British traders and Sioux, Ojibways, and other Indians of the Northwest, in the first instance; in the second place, to display that emblem of authority among the Osages, Pawnees, and Comanches, and plant that standard of the republic on the still disputed boundary of New Spain in the Southwest. All else that he accomplished was incidental to Wilkinson's main aim. How daring were Pike's exploits, these volumes testify. Their moral effect was enormous; their results proved far-reaching; and some of these are still in evidence of intrepid adventure pushed to successful issue.
