    Clark, York, and Slavery

    by

    The mistake should never be made that the two men were friends. They were master and slave, owner and property, superior and inferior. As close as that relationship was for the many years and countless miles they were by each other’s side, for all the dangers and hardships they shared their relationship always was based on William as master and York as servant.

    by

    Valuable reevaluation of the evidence has accumulated about the building of the Lewis and Clark barge some two hundred years ago. Much of this evidence supports the conclusion that Jacob Myers was the principal builder.

    Medicine on the Trail

    From major crisis such as the death of Sgt. Floyd, Lewis’s gunshot wound, and the illness of Sacagawea to minor events such as sexually transmitted diseases, mosquito-born illnesses, and deep cuts, the medical aspects of the Lewis and Clark Expedition provide an interesting topic of study.

    Scientific Explorations

    Their work in the emerging fields of botany, ethnography, geography, geology, and zoology are now considered classics of early American scientific literature.

    Language

    From clichés and colorful sayings of the time to Native American languages, these pages feature the art of language.

    Horse Travel

    To cross the Rocky Mountains, the Lewis and Clark Expedition needed horses and the skills to manage them. Despite their seemingly constant struggle to find missing and stolen horses, as a kind of calvary unit, they left hoof prints on approximately 1,500 miles of western terrain.

    Trail Diplomacy

    Lewis and Clark left behind among many Indians a legacy of nonviolent contact. Those who came later enjoyed that legacy and too often betrayed it.

    Legacies

    Legacy is a very slippery sort of term. If we could erase our myth concepts of Lewis and Clark … it might reawaken something really extraordinary in our national consciousness.

    A Military Corps

    Throughout the expedition the soldiers were expected to conform to the rules and routines of the frontier soldier of 1803.

    The Trail

    Starting with its genesis in Jefferson’s Monticello, Lewis’s training and preparations in Philadelphia, and the barge’s excursion down the Ohio River, the route they took, often called the Lewis and Clark Trail, crosses the continent weaving an epic tale of western exploration treasured by many today.

    Louisiana’s Purchase

    The President’s representatives in Paris had bargained successfully with Napoleon’s bureaucrats not only to buy the port of New Orleans, then the keystone of the continent, but also to acquire, at three cents an acre, an area extending from the Mississippi River to . . . where? No one knew until Meriwether Lewis stood at the crest of the Rocky Mountains at a place known today as Lemhi Pass, on 12 August 1805.

    The Boats

    Starting at Pittsburgh, traveling to the Pacific Ocean, and then returning to St. Louis, the Lewis and Clark Expedition traveled approximately 10,600 miles. Of that, 85%—over 9,000 miles—was by boat. To understand travel in the early 1800 American West is to understand the boats and challenges of river navigation.

    Hunting and Fishing

    Although hunting and fishing were often considered a ‘gentleman’s sport’ especially in Europe, hunting and fishing for Native Americans and Americans alike were a matter of survival. The success of the Lewis and Clark Expedition depended on the success of its hunters.

    Related Explorers

    Lewis and Clark were among several significant explorers of North America both before and after the expedition.

    People

    The success of the Lewis and Clark Expedition was due to its many members and the people they met, including politicians, Eastern gentleman scientists, traders, and the many people already living in the American west.

    The Fur Trade

    Given President Jefferson’s directive to establish commerce, the captains worked extensively within a long-established network of North American fur trade. Part of their mission was to help establish the United States of America’s position within that industry.

    The Arts

    Because of the literate journalists, historians and visual artists can tell the Expedition’s story. When they celebrated with song and dance, we too can share in the experience.

    Learn about the people—and one dog—who were members of the Lewis and Clark Expedition.

    Tools and Techniques

    Other Topics

    Other topics include music, holidays, High Potential Historic Sites, and an index of articles from We Proceeded On.

    Native American Nations

    The Lewis and Clark Expedition benefited from the Indians’ knowledge and support. Maps, route information, food, horses, open-handed friendship—all gave the Corps of Discovery the edge that spelled the difference between success and failure.
