From Chapter 4:
Mrs. Alice Morse Earle, in her interesting book, abounding in curious information, on "The Sabbath in Puritan New England," says that the use of tobacco "was absolutely forbidden under any circumstances on the Sabbath within two miles of the meeting-house, which (since at that date all the houses were clustered round the church-green) was equivalent to not smoking it at all on the Lord's Day, if the law were obeyed. But wicked backsliders existed, poor slaves of habit, who were in Duxbury fixed 10s. for each offence, and in Portsmouth, not only were fined, but to their shame be it told, set as jail-birds in the Portsmouth cage. In Sandwich and in Boston the fine for 'drinking tobacco in the meeting-house' was 5s. for each drink, which I take to mean chewing tobacco rather than smoking it; many men were fined for thus drinking, and solacing the weary hours, though doubtless they were as sly and kept themselves as unobserved as possible. Four Yarmouth men—old sea-dogs, perhaps, who loved their pipe—were in 1687 fined 4s. each for smoking tobacco around the end of the meeting-house. Silly, ostrich-brained Yarmouth men! to fancy to escape detection by hiding around the corner of the church; and to think that the tithing-man had no nose when he was so Argus-eyed."

From Chapter 8:
No doubt smoking had its ups and downs at the Universities apart from the set of the main current of fashion. We learn from the invaluable Gunning that at Cambridge about 1786 smoking was going "out of fashion among the junior members of our combination-rooms, except on the river in the evening, when every man put a short pipe in his mouth." "I took great pains," he adds, "to make myself master of this elegant accomplishment, but I never succeeded, though I used to renew the attempt with a perseverance worthy of a better cause." About the same time Dr. Farmer was Master of Emmanuel and the Master was an inveterate smoker. Gunning says that Emmanuel parlour under Farmer's presidency was always open to those who loved pipes and tobacco and cheerful conversation—a very natural collocation of tastes. Farmer's silver tobacco-pipe is still preserved in his old college, while Porson's japanned snuff-box is at Trinity.
