From Chapter 3:
The number of shops where tobacco was sold in the early days of its triumph seems to have been extraordinary. Barnaby Rich, one of the most prolific parents of pamphlets in an age of prolific writers, wrote a satire on "The Honestie of this Age," which was printed in 1614. In this production Rich declares that every fellow who came into an ale-house and called for his pot, must have his pipe also, for tobacco was then a commodity as much sold in every tavern, inn and ale-house as wine, ale, or beer. He goes on to say that apothecaries' shops, grocers' shops, and chandlers' shops were (almost) never without company who from morning to night were still taking tobacco; and what a number there are besides, he adds, "that doe keepe houses, set open shoppes, that have no other trade to live by but by the selling of tobacco." Rich says he had been told that a list had been recently made of all the houses that traded in tobacco in and near about London, and that if a man might believe what was confidently reported, there were found to be upwards of 7000 houses that lived by that trade; but he could not say whether the apothecaries', grocers' and chandlers' shops, where tobacco was also sold, were included in that number. He proceeds to calculate what the annual expenditure on smoke must be. The number of 7000 seems very large and is perhaps exaggerated. Round numbers are apt to be over rather than under the mark.

From Chapter 8:
Dr. Farmer was elected Master of Emmanuel in 1775. Years before he had held the curacy of Swavesey, about nine miles out of Cambridge, where he regularly performed the duty. After morning service it was his custom to repair to the local public-house where he enjoyed a mutton-chop and potatoes. Immediately after the removal of the cloth, "Mr. Dobson (his churchwarden) and one or two of the principal farmers, made their appearance, to whom he invariably said, 'I am going to read prayers, but shall be back by the time you have made the punch.' Occasionally another farmer accompanied him from church, when pipes and tobacco"—with the punch—"were in requisition until 6 o'clock." The Sabbath afternoon thus satisfactorily concluded, Farmer returned to college in Cambridge and took a nap, till at nine he went to the parlour of the college where the Fellows usually assembled, and pipes and tobacco concluded a well-spent day.
