Diary of John Adams, volume 1
This day removed to my Chamber, and made a Fire. The Forenoon was Spent in Conversation with Zab, in walking to Dr. Turners, and up Pens Hill, and this afternoon in Conversation with Grindal Rawson and Zab at Mrs. Marshes. Yet I have caught several snatches of Reading and Thinking, in Blackstone, Gilbert &c. But I, as usual, expect great Things from this Chamber, and this Winter.1
This entry fixes the date of JA’s fitting out and establishing himself in his law office in the house now known as the John Quincy Adams Birthplace, which he had inherited from his father (see entry of 24 Oct. 1762, note) and which the Savils must by now have vacated. The law office was in the southeast room on the ground floor and JA opened a new doorway into it from the street. During the 19th century the doorway was boarded over but it has since been restored.
