To Mr. Waterston he wrote, Aug. 25, 1844:—
Your books have been a rich mine, in which I have been working with ardor. I have read several volumes, which I had never met before. I hope to send with this the volumes of autographs, which gratified my sister as well as myself. I think I have at my office a pleasant note from Rogers, received during the last year, which is at your service. You have his likeness, but I believe no good autograph of his. Grateful for your kindness, and particularly your friendly thoughts of me in my illness, believe me sincerely yours.
