And what manner of men were in charge of this expedition, thus filled with both interest and peril? Meriwether Lewis was the leader of the party. He was a captain in the U. S. Army who was well known to Jefferson and who had been selected by him as possessed of the endurance, boldness, and energy which made him the fittest man within Jefferson’s knowledge for the duties of commander. His whole life, from his boyhood days in Virginia, had been one of bold adventure. It is related that at the tender age of eight, he was already illustrious for successful midnight forays upon the coon and possum. He had not received a scientific education, but immediately upon receiving the appointment of commander of the expedition, he entered with great energy upon the acquisition of knowledge along geographical lines which would best fit him for preserving an accurate record of his journey. William Clark, the lieutenant of the expedition, was also a United States officer, a man of very good judgment, boldness, and skill in organising his work, and readiness in meeting every kind of emergency. The party was made up of fourteen United States regular soldiers, nine Kentucky volunteers, two French voyageurs, a hunter, an interpreter and a negro servant. The soldiers were offered the munificent bounty of retirement upon full pay, with a grant of land. By Jefferson’s directions, the party were encouraged to keep complete records of all they saw and did. They carried out the instruction so fully that seven journals besides those of Lewis and Clark themselves, were carefully kept, and in them a record was made of every important, as well as unimportant, discovery, even down to the ingredients of their meals and their doses of medicine. It is safe to say that no expedition was ever more fully or accurately reported. Although not a single one of the party possessed literary attainments, there is nevertheless a singular charm about the combined record which has been recognised to this day by repeated editions of the work. It was well understood that the success of the expedition depended largely upon making friends with the Indians, and the explorers were therefore completely fitted out with beads, mirrors, knives, and all manner of trinkets.

The summer of 1804 was spent in an easy and uneventful journey of five months up the Missouri to the country of the Mandan Indians, in what is now Dakota. There they determined to winter. The winter was devoted to making the acquaintance of Indians and to collecting botanical and zoölogical specimens, of which they sent President Jefferson a large amount by a portion of the party which now left them and descended the River. And, while speaking of their relations to Indians, it is very interesting to note the attitude Jefferson instructed them to take in respect to the native tribes. He insisted upon a policy of peace and good-will toward all the tribes upon the route. It is observable that Jefferson refers in a most considerate and friendly manner to the Indians, and instructs the explorers to arrange, if possible, to have some of the more important chiefs induced to come back with the explorers to the city of Washington. He also points out the desirability of urging any bright young Indians to receive such arts as might be useful to them when in contact with the white men. Jefferson even goes so far as to advise the explorers to take along vaccine matter that the Indians might be instructed in the advantages of vaccination. A number of medallion medals were made that were intended to be given as presents to Indian chiefs, the inscription of which was “Peace and Friendship,” with the design of clasped hands. These medals, it may be remarked, seem to have been prized by the Indians as among their greatest treasures. Several of them have been found in Indian graves; one even in a grave of the Nez Percé Indians in Idaho.

While among the Mandans, the expedition was joined by the most attractive personage in it, that is to say, Sacajawea. This young Indian woman, the only woman in the expedition, seems to have furnished the picturesque element in the composition of the party, and she has in later days become the subject of great interest on the part of students of Pacific Coast history.

On April 7th, everything was in readiness for resuming their journey up the River. The explorers embarked again in a squadron of six canoes and two pirogues.

On the twelfth day of August, an advance party of the explorers crossed the Great Divide of the Rocky Mountains, the birthplace of mighty rivers. Descending the western slope, they found themselves in the country of the Shoshone Indians. Captain Lewis was leading this advance expedition, and, as he neared the highest point of the pass, he realised the significance of the transition from the waters of the Missouri to those of the Columbia. A quotation from his narrative at this most interesting point of the journey gives the reader a better conception than any description could, of the feelings of the explorers:

The road was still plain, and as it led directly toward the mountains, the stream gradually became smaller, till after their advancing two miles further, it had so greatly diminished in width that one of the men in a fit of enthusiasm, with one foot on each side of the rivulet, thanked God that he had lived to bestride the Missouri. As they proceeded, their hope of seeing the waters of the Columbia rose to almost painful anxiety; when at the distance of four miles from the last abrupt turn of the stream, they reached a small gap formed by the high mountains which recede on either side, leaving room for the Indian road. From the foot of one of the lowest of these mountains, which arises with a gentle ascent of about half a mile, issued the remotest water of the Missouri. They had now reached the hidden sources of that river, which had never before been seen by civilised man; and as they quenched their thirst at the chaste and icy fountain,—as they sat down by the brink of that little rivulet, which yielded its distant and modest tribute to the parent ocean,—they felt themselves rewarded for all their labours and difficulties. They left reluctantly this interesting spot, and pursuing the Indian road through the interval of the hills, arrived at the top of a ridge from which they saw high mountains, partially covered with snow, still to the west of them. The ridge on which they stood formed the dividing line between the waters of the Atlantic and the Pacific Oceans. They found the descent much steeper than on the eastern side, and at the distance of three-quarters of a mile, reached a handsome, bold creek of cold, clear water running to the westward. They stopped to taste for the first time the waters of the Columbia.

The party was now upon the western slope of the Great Divide, in the vicinity of the present Fort Lemhi in Eastern Idaho. They supposed that they were almost to the Pacific, not realising that a thousand miles of difficult and dangerous travel and more than two months of time still separated them from their wished-for goal. The journey, in fact, from the springs of the Missouri to the navigable waters of the Columbia, proved to be the most critical of the whole series.

Soon after passing the crest of the mountains, the party encountered a band of sixty Indians of the Shoshone tribe, coming to meet them at full speed, upon fine horses, and armed for battle. Captain Lewis, who always showed great discretion with Indians, took the Stars and Stripes in his hand, and advanced alone to meet the party. As soon as the Indians perceived that he was a white man, they showed signs of great rejoicing, and the three leaders of the war-party, dismounting, embraced the American captain with great exuberance, shouting words which he afterwards discovered meant, “We are rejoiced! We are rejoiced!” The valiant captain, however, was much more pleased with the hearty good-will of their intentions than in the manner of its expression, inasmuch as they had transferred a good portion of the war paint from their own faces to his. Lewis now brought up his companions and entered upon a long and friendly conference with the chief of the party, whose name was Cameahwait. Captain Lewis, as the representative of the great American nation, set forth to the eager listeners about him, a glowing report as to the benevolence of the Great Father at Washington, and his desire that his brothers of the West should come into friendly relations with him and trade their furs for the beads and blankets and knives which the Indians so highly prize. He also explained to them that they would receive from his government guns and ammunition which would enable them to cope with the dreaded Sioux or the pitiless Blackfeet. Captain Lewis also greatly aroused the curiosity of these Indians by indicating to them that he had with him a woman of their tribe, and also a man who was perfectly black and yet not painted. He now made a proposition to Cameahwait to go back with him and his companions to the forks of the Missouri where they had left the main party with their goods and boats. Cameahwait very gladly agreed to do this and also to provide them with horses for the journey westward to the navigable waters of the Columbia.
