There is something of the simplicity of real grandeur in the commonplace records of the leaders of this expedition. "They were men with no pretensions to scientific learning," writes Roosevelt, "but they were singularly close and accurate observers and truthful narrators. Very rarely have any similar explorers described so faithfully not only the physical features, but the animals and plants of a newly discovered land. ... Few explorers who did and saw so much that was absolutely new have written of their deeds with such quiet absence of boastfulness, and have drawn their descriptions with such complete freedom from exaggeration." The very absence of incident in the story is significant to one who remembers the countless dangers that beset Lewis and Clark as they fared slowly on up the long, tiresome stretches of the Missouri; surprises, accidents, misunderstandings, miscalculations, and mutinies might have been the order of the day; a dozen instances could be cited of parties making journeys far less in extent than that now under consideration where the infelicities of a single week surpassed those known throughout those three years. These splendid qualities, which can hardly be emphasized save in a negative way, make this expedition as singular as it was auspicious in our national annals. Good discipline was kept without engendering hatred; the leaders worked faithfully with their men at the hardest and most menial tasks; in suffering, risking, laboring, they set examples to all of their party. In dealing with the Indians good judgment was used; even in the land of the fierce Dakotas they escaped harm because of great diplomacy, presenting a more bold and haughty front than could perhaps have been maintained if once it had been challenged. With all Indian nations conferences were held, at which the purchase of Louisiana from France was officially announced, and proper presents were distributed in sign of the friendship of the United States.
