NH, XI, 94. No trace of the original letter has been found, and the text in the source is open to question. A footnote in the source is as follows: ``General Van Alen wrote Lincoln, requesting him, for the sake of his friends and the nation, to guard his life and not expose it to assassination as he had by going to Richmond. The above reply was written on the very day Lincoln was assassinated. Its discovery is due to the enthusiastic research of Mr. Gilbert A. Tracy, of Putnam, Conn.'' The purported letter from Van Alen is not in the Lincoln Papers.
