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:
It seems to have been taken for granted that country parsons smoked. smoking was universal among their male parishioners from the squire to the labourer (when he could afford it), so that it was only natural that the parson, with little to do, and in those days not too much inclination to do it, should be as fond of his pipe as the rest of the world around him. In a World of 1756 there is an account of a country gentleman entertaining one evening the vicar of the parish, and the host as a matter of course proceeds to order a bottle of wine with pipes and tobacco to be placed on the table. The vicar forthwith "filled his pipe, and drank very cordially to my friend," his host. One cannot doubt that Laurence Sterne, that most remarkable of country parsons, smoked. His "My Uncle Toby" is among the immortals, and Toby without his pipe is unimaginable.
