From Chapter 2:
In the afternoon the gallant might attend what Dekker calls a "Tobacco-ordinary," by which may possibly have been meant a smoking-club, or, more probably, the gathering after dinner at one of the many ordinaries in the neighbourhood of St. Paul's Cathedral of "tobacconists," as smokers were then called, to discuss the merits of their respective pipes, and of the various kinds of tobacco—"whether your Cane or your Pudding be sweetest."

Of course he often bragged, like Julio in Day's "Law Trickes": "Tobacco? the best in Europe, 't cost me ten Crownes an ounce, by this vapour."

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.
