From Chapter 1:
At the fifteenth-century Manor-House at South Wraxall, Wiltshire, the "Raleigh Room" is shown, and visitors are told that according to local tradition it was in this room that Sir Walter smoked his first pipe, when visiting his friend, the owner of the mansion, Sir Henry Long.

From Chapter 7:
Hogarth himself was a confirmed pipe-lover. When he and Thornhill and their three companions set out from Gravesend for the final stage, up the river, of their famous "Five Days Peregrination," we are told that they hired a boat with clean straw, and laid in a bottle of wine, pipes, tobacco, and light, and so came merrily up the river. The arm-chair in which Hogarth was wont to sit and smoke is still preserved in his house at Chiswick, which has been bought and preserved as a memorial of the moralist-painter; and in the garden of the house may still be seen the remains of the mulberry tree under which Mr. Austin Dobson suggests that Hogarth and Fielding may have sat and smoked their pipes together in the days when George was King.
