Although there were previous initiatives to explore the western continent, the Lewis and Clark Expedition begins here when Thomas Jeffersonn wrote a letter to James Wilkinson with a request that Meriwether Lewis be the President’s personal secretary in February 1801. Before leaving for Pittsburgh in July 1803, Lewis traveled between Jefferson’s home Monticello, Washington City, Harpers Ferry, and Philadelphia as plans coalesced and preparations ensued.
Lewis’s Estimate of Expenses
by Kristopher K. TownsendPrior to Jefferson’s annual message to Congress on 15 December 1802, Lewis prepared a roughly itemized estimate of $2500 as the cost of the expedition.
After some eight months of planning and discussion, President Thomas Jefferson handed his twenty-eight-year-old secretary, Captain Meriwether Lewis, a letter containing instructions for the conduct of one of the most significant undertakings in American history.
When Meriwether Lewis traveled to Philadelphia in 1802, his guide to the city was Mahlon Dickerson who gave him a survey of people and places well beyond the privilege or opportunity of most Philadelphians of the time.
In this brief extract from We Proceeded On, the quarterly journal of the Lewis and Clark Trail Heritage Foundation, Carol MacGregor explains the beginning and purpose of the American Philosophical Society and its connection to the Lewis and Clark Expedition.

Harpers Ferry by Air
Wedge of history
Harpers Ferry’s tiny footprint belies the richness of its roles in American history—in industrialization, in commerce, and especially in the unfolding of the Civil War and the long struggle of African-Americans out of slavery.
Early American Flags
by Joseph A. MussulmanLewis’s long list of needs for the journey would have been a large supply of American flags, to be flown on their boats, over their camps, and at their council sites. Leading up to the Lewis and Clark expedition, what did the young country’s flags look like?
Considering all he had to do to prepare for the expedition, Lewis was fortunate in that he could rely on a small cadre of Army personnel to help him assemble, pack, and ship his supplies.
It was Thomas Jefferson who gave cryptography in America its greatest impetus. Sometime in 1803 Jefferson presented Meriwether Lewis with a cipher based on a square table or tableau used to create a substitution cipher.
Moving between Philadelphia and Washington City in 1803, Lewis devised a plan for recruiting personnel while traveling to St. Louis. Plan A was to go down the Cumberland River, Plan B, the Ohio.
During the planning and preparations for the Western Expedition, Thomas Jefferson practiced selective levels of secrecy.
In his capacity as the President’s secretary, Meriwether Lewis prepared a report in which he classified the Army’s officers by military merit and by political affiliation, if known. Both of these factors were considered in identifying candidates for dismissal.

News from Capt. Stoddard
Fort Fayette, PA Capt. Amos Stoddard writes a letter to Col. Henry Burbeck informing the latter that he has arrived at Pittsburgh and is awaiting further orders. Those orders would be connected to what would later become the Lewis and Clark Expedition.
The Corps of Discovery, as it would be called, or the “corps of volunteers for North Western Discovery,” as Lewis put it, epitomized the rising glory of the United States—its sense of limitless possibilities and unparalleled opportunities.
The President’s Secretary
by Arlen J. LargeIt was 4 March 1801, Inauguration Day for the third president. Nine days previously Jefferson had asked Meriwether Lewis to serve as his private secretary in the raw new mansion called the President’s House.
The Louisiana Purchase
by Pierce MullenEaster week in Paris, 1803, was truly momentous for the young United States of America. The American Minister to France, Robert R. Livingston was sent to discuss the difficult question of New Orleans, the Mississippi and Franco-American relations.
The story of what was known by his detractors as “Jefferson’s War,” opens for us a narrow window on a little known but intriguing episode in Meriwether Lewis’s brief position as the President’s secretary.
During preparations, Lewis relied on the Harpers Ferry Armory and Arsenal for the guns and hardware that would meet his unique requirements.
