no. Smithsonian institution, Washington d.c. April 28th, 1871. dear Mother, The manuscript which you so kindly sent to me arrived this morning. It was just what I wanted. Please send one [of] those blank books you speak of—particularly those which contain measurements and notes of birds made at home. I have not made my visit to New York yet, but will probably go next week. Mother, I am happy to announce to you that there is a prospect of my coming home this summer—about the same time that I did last year—though I won’t be certain about it. I shall try my best to come. Tell poor neglected, but dearly loved, Francy that I will answer her nice letter the very first opportunity that I have; and that I am really ashamed of myself for having neglected her for so long, but my excuse is that I am so terribly busy all the time.
