From Chapter 3:
Trickery of another kind is revealed in a scene in Chapman's play "A Humorous Day's Mirth," 1599. A customer at an ordinary says: "Hark you, my host, have you a pipe of good tobacco?" "The best in the town," says mine host, after the manner of his class. "Boy, dry a leaf." Quietly the boy tells him, "There's none in the house, sir," to which the worthy host replies sotto voce, "Dry a dock leaf." But the diner's potations must have been powerful if they had left him unable to distinguish between the taste of tobacco and that of dried dock-leaf.

From Chapter 7:
At another inn a country squire is discovered smoking his pipe by the door and the parson promptly joins him. Again, he smokes before he goes to bed, and before he breakfasts the next morning; and when he goes into the inn garden with the host who is willing to trust him, both host and parson light their pipes before beginning to gossip. Farther on, when the hospitable Mr. Wilson takes the weary wayfarers in, Parson Adams loses no time in filling himself with ale, as Fielding puts it, and lighting his pipe. The menfolk—Wilson, Adams and Joseph—have to spend the night seated round the fire, but apparently Adams is the only one who seeks the solace of tobacco. It is significant that Wilson, in telling the story of his dissipated early life, classes smoking with "singing, holloaing, wrangling, drinking, toasting," and other diversions of "jolly companions."
