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.

From Chapter 14:
Another eighteenth-century clerical worthy, the famous Dr. Parr, an inveterate smoker, was accustomed to do what Mr. Disney prevented Archbishop Blackburn from doing—he smoked in his vestry at Hatton. This he did before the sermon, while the congregation were singing a hymn, and apparently both parties were pleased, for Parr would say: "My people like long hymns; but I prefer a long clay."

Robert Hall, the famous Baptist preacher, having once upon a time strongly denounced smoking as an "odious custom," learned to smoke himself as a result of his acquaintance with Dr. Parr. Parr was such a continual smoker that anyone who came into his company, if he had never smoked before, had to learn the use of a pipe as a means of self-defence. Hall, who became a heavy smoker, is said to have smoked in his vestry at intervals in the service. He probably found some relief in tobacco from the severe internal pains with which for many years he was afflicted.
