1James M. Davis wrote and signed this letter. Davis wrote another letter to Abraham Lincoln the same day.
2Justin H. Butterfield, James L. D. Morrison, and Cyrus Edwards were vying to become commissioner of the U.S. General Land Office. Lincoln entered the competition after learning that Butterfield was favored over Morrison and Edwards.
As competition for the job intensified, William H. Henderson and Josiah M. Lucas, Lincoln supporters living in Washington, DC, urged Lincoln to come to the nation’s capital to personally lobby for the position. On June 9, Butterfield wrote Lincoln suggesting that neither go to Washington. Lincoln did not respond to this suggestion, and on June 10, both set out for the capital. Lincoln arrived on or before June 19. See the General Land Office Affair.
3This is a reference to people from southern Illinois sending letters in support of Lincoln to President Zachary Taylor. Thomas Ewing was the secretary of the U.S. Department of the Interior, but Taylor was ultimately responsible for appointing the commissioner of the U.S. General Land Office.
4Nil desperandum means nothing must be despaired of or despair of nothing.
Ultimately, neither Morrison, Edwards, nor Lincoln received the appointment; the job went to Butterfield instead. See the General Land Office Affair.
