ALS, ICHi.
 This letter is not extant, Lincoln's quotations from it being the only source for its contents.
 The Morgan Journal for this date is not extant, but the article referred to was copied by the Illinois Gazette, February 14, 1846. It argued against Lincoln's principle of rotation in office and published the fact that Hardin had proposed a district Whig poll to replace the convention system, and also the fact of Lincoln's having declined to support the proposal---which facts could have come to light only through Hardin's having revealed the content of Lincoln's letter of January 19.
