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 8:
Parr was not a model smoker. He was brutally overbearing towards other folk, and would accept no invitation except on the understanding that he might smoke when and where he liked. It was his invariable practice, wherever he might be visiting, to smoke a pipe as soon as he had got out of bed. His biographer says—"The ladies were obliged to bear his tobacco, or to give up his company; and at Hatton (1786-1825) now and then he was the tyrant of the fireside." Parr was capable of smoking twenty pipes in an evening, and described himself as "rolling volcanic fumes of tobacco to the ceiling" while he worked at his desk. At a dinner which was given at Trinity College, Cambridge, to the Duke of Gloucester, as Chancellor of the University, when the cloth was removed, Parr at once started his pipe and began, says one who was present, "blowing a cloud into the faces of his neighbours, much to their annoyance, and causing royalty to sneeze by the stimulating stench of mundungus." It is surprising that people were willing to put up with such bad manners as Parr was accustomed to exhibit; but his reputation was then great, and he traded upon it.
