"The report embraces a description of the portion of the river examined and the lands in its vicinity, and also of the other portions of the Upper Columbia and the country drained by it and its tributaries." "I have sought to show the economical relations of the Columbia to the surrounding country, and the importance of making that portion of it lying within the territory of the United States navigable as far as practicable, and have suggested a plan for doing so."
