ALS, owned by Kingman Brewster, Washington, D. C. On the verso Martin has noted: ``One to M[E]AGHER/ 25.th January 1851.'' Below this notation he has copied the following, presumably the telegram which Thomas Meagher had sent: ``To Michael McCormack/care of James Lamb./ Springfield Ill, 24 Jan 1851./ Your [horse?] is bad. Cannot/ work any longer He is sick/ dont want to keep him any/ longer/ Thos Meagher.'' As Lincoln's letter of July 26 (infra) indicates, he found the telegram to Meagher later, but could not identify the writer. James L. Lamb was a prominent merchant of Springfield. Thomas F. Meagher, the Irish patriot, seems an extremely unlikely candidate for the authorship of the telegram but he is the only Meagher mentioned in contemporary newspapers. Michael McCormack likewise has not been identified.
