ALS, IHi.
 Speed had returned to Springfield with Lincoln in September, 1841, but was now returning to Kentucky to live and to marry Miss Fanny Henning. The date given to this letter by Nicolay and Hay has been followed as presumably the date assigned to it by Speed for the Complete Works, but Speed wrote Herndon, September 17, 1866, that he remained in Springfield until the ``1st of Jany. 1842'' (DLC-HW). In any event, Lincoln wrote the letter before Speed's departure and presumably gave it to him before he left. There is no postmark to indicate that the letter went through the mail.
