from many who eagerly volunteered their services; two French voyageurs, or watermen, one of whom was an interpreter of Indian language, and the other a hunter; and one black man, a servant of Captain Clark.  All these, except the negro servant, were regularly enlisted as privates in the military service of the United States during the expedition; and three of them were by the captains appointed sergeants.  In addition to this force, nine voyageurs and a corporal and six private soldiers were detailed to act as guides and assistants until the explorers should reach the country of the Mandan Indians, a region lying around the spot where is now situated the flourishing city of Bismarck, the capital of North Dakota.  It was expected that if hostile Indians should attack the explorers anywhere within the limits of the little-known parts through which they were to make their way, such attacks were more likely to be made below the Mandan country than elsewhere.

The duties of the explorers were numerous and important.  They were to explore as thoroughly as possible the country through which they were to pass; making such observations of latitude and longitude as would be needed when maps of the region should be prepared by the War Department; observing the trade, commerce, tribal relations, manners and customs, language, traditions, and monuments, habits and industrial pursuits, diseases and laws of the Indian nations with whom they might come in contact; note the floral, mineral, and animal characteristics of the country, and, above all, to report whatever might be of interest to citizens who might thereafter be desirous of opening trade relations with those wild tribes of which almost nothing was then distinctly known.

The list of articles with which the explorers were provided, to aid them in establishing peaceful relations with the Indians, might amuse traders of the present day.  But in those primitive times, and among peoples entirely ignorant of the white man’s riches and resources, coats richly laced with gilt braid, red trousers, medals, flags, knives, colored handkerchiefs, paints, small looking-glasses, beads and tomahawks were believed to be so attractive to the simple-minded red man that he would gladly do much and give much of his own to win such prizes.  Of these fine things there were fourteen large bales and one box.  The stores of the expedition were clothing, working tools, fire-arms, food supplies, powder, ball, lead for bullets, and flints for the guns then in use, the old-fashioned flint-lock rifle and musket being still in vogue in our country; for all of this was at the beginning of the present century.

As the party was to begin their long journey by ascending the Missouri River, their means of travel were provided in three boats.  The largest, a keel-boat, fifty-five feet long and drawing three feet of water, carried a big square sail and twenty-two seats for oarsmen.  On board this craft was a small swivel gun.  The other two boats were of that variety of open craft known as pirogue, a craft shaped like a flat-iron, square-sterned, flat-bottomed, roomy, of light draft, and usually provided with four oars and a square sail which could be used when the wind was aft, and which also served as a tent, or night shelter, on shore.  Two horses, for hunting or other occasional service, were led along the banks of the river.
