From Chapter 4:
From the various entries in the "Diary" relating to the purchase of tobacco, it seems clear that there was no shop in Exeter devoted specially or exclusively to the sale of the weed. Hayne bought his supplies from four of the leading goldsmiths of the city, who can be identified by the fact that he had dealings with them in their own special wares, also from two drapers, one grocer, and four other tradesmen (on a single occasion each) whose particular occupations are unknown.

From Chapter 6:
Grave wits, who, spending farthings four,
Sit, smoke, and warm themselves an hour.

The allusions in the Spectator to smoking in the coffee-houses are frequent. "Sometimes," says Addison, in his title character in the first number of the paper, "sometimes I smoak a pipe at Child's and whilst I seem attentive to nothing but the Post-man, over-hear the conversation of every table in the room." And here is a vignette of coffee-house life in 1714 from No. 568 of the Spectator: "I was yesterday in a coffee-house not far from the Royal Exchange, where I observed three persons in close conference over a pipe of tobacco; upon which, having filled one for my own use, I lighted it at the little wax candle that stood before them; and after having thrown in two or three whiffs amongst them, sat down and made one of the company. I need not tell my reader, that lighting a man's pipe at the same candle is looked upon among brother-smoakers as an overture to conversation and friendship." From the very beginning smoking has induced and fostered a spirit of comradeship.
