Jefferson to Benjamin Rush
Washington, Feb. 28. 1803
Dear Sir
Capt. Lewis is brave, prudent, habituated to the woods, & familiar with Indian manners & character. He is not regularly educated, but he possesses a great mass of accurate observation on all the subjects of nature . . . . He has qualified himself for those observations of longitude & latitude necessary to fix the points of the line he will go over.
