These messengers of the United States were true Long Knives: young Captain Meriwether Lewis of Virginia and Lieutenant William Clark, his friend and a brother of the famed General George Rogers Clark, of Kentucky. They were to report upon the nature of the northern Louisiana Purchase, talk friendship with the strange Indians, and find a way by water across the Oregon Country beyond, to the mouth of the Columbia. They took a company of thirty-one men enlisted as soldiers and boatmen and interpreters. Among them there were nine of the Kentucky Long Hunters. It is said that Lewis Wetzel joined, but he dropped out. John Colter, of Maysville on the Ohio River at the mouth of Limestone Creek, opposite West Virginia, was another. He went through. Ten years before, Daniel Boone had moved west, into Louisiana Province while it was owned by Spain. He had settled in central Missouri, on the Missouri River above St. Louis; wanted "elbow room," he said--and the Spanish governor gave him eight thousand five hundred acres of land. Colonel Boone the Big Turtle was the first of the American dead-shots in the new West. When the Lewis and Clark men toiled up-river here he still was, living among the French in the very last white settlement. He was not to be alone long. Many another Kentuckian and Carolinan and Tennesseean and Virginian had been thinking of a try at Boone's latest hunting-grounds; they remembered that he had made a good choice when he picked Kentucky: and now that the country yonder was being opened by Americans for Americans they pressed after Lewis and Clark--their own kind. There were furs to be found, under American protection, and sold at St. Louis, an American city. So when in the summer of 1806 the Lewis and Clark men were on the down-river trail, bound for St. Louis again, on the Missouri below the mouth of the Yellowstone River away up in North Dakota they met two American trappers, Forest Hancock and Joseph Dickson, hailing last from Illinois. John Colter, of the nine Kentuckians, thought that this was a good chance for him. The two free-trappers had been in here for two years--had set out right on the heels of the exploring party; they had caught many beaver and were doing well. They turned back, for fifty miles, with the company. On the way down John Colter arranged to become their partner. Captain Lewis gave him his discharge; and instead of going home he stayed, to be a trapper.
