Inscription.  Under the direction of President Thomas Jefferson, the Louisiana Purchase of 1803 — the largest single land deal in the history of the United States — doubled the size of the young nation. Napolean Bonaparte of France, whose dream for an empire in America had been dashed, sold the territory of 600 million acres for $15 million, or approximately 4˘ per acre.

The acquisition, acquired as a result of the successful negotiating efforts of Robert R.
