NATIONAL INTELLIGENCER, Washington, D.C., Aug. 26, 1807  The back page has a very lengthy: "Proposals...For Publishing LEWIS and CLARK'S Tour to the Pacific Ocean, through the Interior of the Continent of North America..." noting the details that will be in "Volume First" as well as "Volume Second". And this is followed by another descriptive notice headed: "Lewis & Clark's Map of North America..." with many details. All this takes an entire column.
All of the front page is taken up with: "Trial of Aaron Burr" with considerable detail.
Four pages, very nice condition.

Note: recent auction sales of this identical title and Lewis & Clark content have sold for $1912 and $2000 each.
