From Chapter 3:
Some of the apothecaries whose shops were in most repute for the quality of the tobacco kept, took pupils and taught them the "slights," as tricks with the pipe were called. These included exhaling the smoke in little globes, rings and so forth. The invaluable Ben Jonson, in the preliminary account of the characters in his "Every Man out of his Humour," 1600, describes one Sogliardo as "an essential clown ... yet so enamoured of the name of a gentleman that he will have it though he buys it. He comes up every term to learn to take tobacco and see new motions." Sogliardo was accustomed to hire a private room to practise in. The fashionable way was to expel the smoke through the nose. In a play by Field of 1618, a foolish nobleman is asked by some boon companions in a tavern: "Will your lordship take any tobacco?" when another sneers, "'Sheart! he cannot put it through his nose!" His lordship was apparently not well versed in the "slights."

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.
