The extension of commerce1 among the Indian tribes might be worthy of the attention of Congress. The land along the Missouri River is inhabited by numerous tribes, who have great supplies of furs.

An intelligent officer, with ten or twelve chosen men, might explore the whole Missouri River. They could have conferences with the natives on the subject of commerce, get permission from the natives for our traders to enter the lands, and return with the information acquired in the course of two summers. All that the men could carry would be weapons and supplies, some instruments of observation, and light and cheap presents for the Indians.

European nations have encountered great expense to enlarge their boundaries through voyages of discovery. Our nation for the same reasons, as well as for its own interests, should explore the only line of easy communication across the continent.

The interests of commerce are within the constitutional powers and care of Congress. That the voyage should advance the geographical knowledge of our own continent is an additional benefit.
