From Chapter 2:
A curious feature of tobacco-manners among fashionable smokers of the period was the practice of passing a pipe from one to another, after the fashion of the "loving cup." There is a scene in "Greene's Tu Quoque," 1614, laid in a fashionable ordinary, where the London gallants meet as usual, and one says to a companion who is smoking: "Please you to impart your smoke?" "Very willingly, sir," says the smoker. Number two takes a whiff or two and courteously says: "In good faith, a pipe of excellent vapour!" The owner of the pipe then explains that it is "the best the house yields," whereupon the other immediately depreciates it, saying affectedly: "Had you it in the house? I thought it had been your own: 'tis not so good now as I took it for!" Another writer of this time speaks of one pipe of tobacco sufficing "three or four men at once."

From Chapter 6:
Sir Roger de Coverley, as a typical country squire, was naturally a smoker. He presented his friend the Spectator, the silent gentleman, with a tobacco-stopper made by Will Wimble, telling him that Will had been busy all the early part of the winter in turning great quantities of them, and had made a present of one to every gentleman in the county who had good principles and smoked. When Sir Roger was driving in a hackney-coach he called upon the coachman to stop, and when the man came to the window asked him if he smoked. While Sir Roger's companion was wondering "what this would end in," the knight bid his Jehu to "stop by the way at any good Tobacconist's, and take in a Roll of their best Virginia." And when he visited Squire's near Gray's Inn Gate, his first act was to call for a clean pipe, a paper of tobacco, a dish of coffee, a newspaper and a wax candle; and all the boys in the coffee-room ran to serve him. The wax candle was of course a convenience in matchless days for pipe-lighting. The "paper of tobacco" was the equivalent of what is now vulgarly called a "screw" of tobacco.
