Wrote to my father as usual this morning. This makes the fortieth letter to him since last October and will probably be the last for some months. I have missed but once or twice, and have seldom been much at a loss for subject. On the whole this is a satisfactory part of the year although if I were to continue it for another, I think I should attempt some thing more. Rode to Boston and spent the morning at the office reading Judge Howe’s Lecture which was rather dull. Also wrote Executive Record and read a little of Cicero. The day was exceedingly cool. Returned to Quincy, worked a little in the Nursery, and in the evening, Conversation with Mrs. Adams.
