Lesson Plan Graphic
THE CRUCIAL ROLE OF LANGUAGE
ON THE LEWIS AND CLARK EXPEDITION


THEME
The physical problems faced by the Corps of Discovery often overshadow the equally difficult communication problems they encountered as they moved farther and farther west. These problems were of three kinds: (1) communicating with western Indian tribes who spoke many different languages (2) recording observations and scientific information in journals under less than favorable conditions, and (3) communicating with President Jefferson in Washington. The lesson plan and activities in this unit relate to one or another of those problems.

GOALS

  • To emphasize the important part played by language, both spoken and written, in the success of the Lewis and Clark Expedition.
  • To expose students to the astonishing variety and complexity of American Indian languages.
  • To demonstrate ways in which the English language has changed over two millennia.
  • To introduce students to the esoteric world of cryptology.

OBJECTIVES
Upon completion of this unit, students will be able to:

  • Comprehend the enormity of the communication challenges that faced the Corps of Discovery.
  • Discuss two ways in which the English language in America has changed since the time of Lewis and Clark.
  • Define or identify: cryptology, enigma machine, linguistics, Code Talkers

IMPLEMENTATION
Introduction
Communication problems faced by Lewis and Clark and the Corps of Discovery are often overshadowed by the sheer physical aspects of the expedition. Rowing boats against the current, encountering grizzly bears, portaging around waterfalls, and crossing rugged mountain ranges make for more exciting stories than how the Corps members communicated.
Nevertheless, some of the most important duties assigned to the Corps involved the use of language in one way or another. One of these duties was to tell the Indian tribes who lived in the Louisiana Territory that the United States now claimed their homelands. The captains were also to discuss trading possibilities with them, and discourage them from trading with the British and French. In the Pacific Northwest, beyond the boundaries of the United States, the captains were instructed to gather information from natives whose languages were completely unknown to them.

Another important duty assigned to the captains was to keep detailed records of what they observed. Jefferson's "need-to-know list" was exhaustive. He wanted information on geography, flora, fauna, weather, minerals, latitude and longitude, customs and languages of western Indian tribes, and much more. (For a copy of Jefferson's instructions to Lewis, click on http://www.mt.net/~rojomo/landc.htm?1.)

The captains also encouraged crew members to keep journals. Four of the men's journals have survived, those of Charles Floyd, Patrick Gass, John Ordway, and Joseph Whitehouse. There may have been other journals that did not survive or have not been discovered. Of course, some members of the Corps of Discovery may not have been able to read or write.

A third duty was to keep Jefferson informed about the progress of the expedition as much as possible. Fearing that messages might be intercepted by those opposed to the expedition, Jefferson taught Lewis how to encode them. If Jefferson's code was ever used by Lewis, no evidence of it has survived.

Apparently, Jefferson heard from the captains only once after they left St. Louis until they returned more than two years later. After spending the winter with the Mandan Indians (near present day Bismarck, North Dakota), several of the boatmen sailed the keelboat back to St. Louis as previously planned. On board were letters and maps from the captains as well as several boxes of flora and fauna specimens and Indian artifacts. On April 3. 1805, Clark wrote in his journal, "we are all day engaged packing up Sundery articles to be sent to the President of the U.S." He then lists the contents of the nine boxes placed on board. Some of these items still exist today in museums and private collections.

Before Lewis left Washington, he and Jefferson discussed the possibility of sending crew members back east at intervals to report on the expedition's progress. As the Corps made its way west, however, it became apparent that such a plan was unfeasible. No member of the tight-knit Corps of Discovery could be spared to carry messages. They were a small group on their own in a vast landscape, and they had to stick together.


CONCLUSION/FOLLOW-UP
Each of these issues about the role of language in the Lewis and Clark Expedition is taken up in more detail in three different activities:

Activity M-1: AMERICAN INDIAN LANGUAGES
One of the most perplexing challenges Lewis and Clark faced on the expedition was communicating with American Indian tribes who spoke many different languages. Over three-hundred languages were spoken by the inhabitants of North America when Europeans discovered the New World. About half of those languages are no longer spoken. In this activity, students conduct research on American Indian languages and the current efforts to preserve those still being spoken.

Activity M-2: "THE KING'S ENGLISH" OF JEFFERSON, LEWIS, AND CLARK
In this activity a book by Thomas Jefferson, and the journals of Lewis and Clark provide the basis for studying changes in the English language over two centuries.

Activity M-3: PRESIDENT JEFFERSON'S SECRET CODE
Secret codes have a long history. At the time of the Lewis and Clark Expedition, secret codes were often used for government business. President Jefferson taught Captain Lewis how to use a secret code for sending messages. In this activity, students learn to code and decode messages using the same code Jefferson and Lewis used.

SUGGESTIONS FOR FURTHER RESEARCH RELEVANT TO THIS UNIT

  • Writing equipment used by Jefferson, Lewis, and Clark
    The quill pen dipped in ink was the principal writing instrument of the day. Lewis and Clark took lap desks with them to hold their writing materials and to provide a flat writing space. Jefferson had so much writing to do, he invented a mechanical "duplicating machine" to copy his documents.
  • Location and condition of the Lewis and Clark Expedition journals
    Many of the original journals and field notes from the expedition still exist. Some of them are owned by the American Philosophical Society of Philadelphia. Clark's field notes are at Yale University, etc.
  • The work of Noah Webster who created the first American English dictionary published in 1806.
    Before he compiled the dictionary, Webster published a standardized spelling book that was widely used in early American schools.
