Excerpt: So, North America at the time of the Lewis and Clark Expedition had two economies. Lewis made his purchases on the basis of one [a $1000 War Department draft in Philadelphia], then, for the most part, left his white man's "wampum" behind, and went forth with the other. Compared to exchanges in a paper economy, the stocking-up preparations took much more attention to detail, and added burden to the keelboat in Pittsburgh. However, he could not have otherwise succeeded. |
