Thomas Jefferson to John Staples, 25 January 1814

To John Staples

Monticello Jan. 25. 14.


Understanding that you are the agent for disposing of mr Oliver Evans’s patent screws for crushing the ear of corn, cob & all for grinding in a mill, I have to ask the favor of you to deliver one for me to mr William Johnson, a waterman of Milton, who will apply to you for it about a week hence. Mr Gibson will be so good as to pay you the price on presenting him this letter.

Accept the assurance of my esteem and respect

Th: Jefferson
