From Chapter 9:
One of the earliest cigar-smokers must have been that remarkable clergyman, the Rev. Charles Caleb Colton, whose "Lacon," published in 1820, was once popular. Colton was in succession Rector of Tiverton and Vicar of Kew, but on leaving Kew became a wine-merchant in Soho. While at Kew he is said to have kept cigars under the pulpit, where, he said, the temperature was exactly right.

At first even cigar-smoking was confined to comparatively few persons, and the social prejudice against tobacco continued unabated. Thackeray significantly makes Rawdon Crawley a smoker—the action of "Vanity Fair" takes place in the first two decades of the nineteenth century. The original smoking-room of the Athenæum Club, which was founded in 1824, the present building being erected in 1830, was a miserable little room, Dr. Hawtree, on behalf of the committee, announcing that "no gentleman smoked." The Oriental Club, when built in 1826-27, contained no smoking-room at all.

From Chapter 14:
Readers of Sir Walter Scott will remember in "The Heart of Midlothian" one curious instance of eighteenth-century smoking in church—in a Scottish Presbyterian church, too. Jeanie Deans's beloved Reuben Butler was about to be ordained to the charge of the parish of Knocktarlitie, Dumbartonshire; the congregation were duly seated, after prayers, douce David Deans occupying a seat among the elders, and the officiating minister had read his text preparatory to the delivery of his hour and a quarter sermon. The redoubtable Duncan of Knockdunder was making his preparations also for the sermon. "After rummaging the leathern purse which hung in front of his petticoat, he produced a short tobacco-pipe made of iron, and observed almost aloud, 'I hae forgotten my spleuchan—Lachlan, gang doon to the Clachan, and bring me up a pennyworth of twist.' Six arms, the nearest within reach, presented, with an obedient start, as many tobacco-pouches to the man of office. He made choice of one with a nod of acknowledgment, filled his pipe, lighted it with the assistance of his pistol-flint, and smoked with infinite composure during the whole time of the sermon. When the discourse was finished, he knocked the ashes out of his pipe, replaced it in his sporran, returned the tobacco-pouch or spleuchan to its owner, and joined in the prayers with decency and attention." David Deans, however, did not at all approve this irreverence. "It didna become a wild Indian," he said, "much less a Christian and a gentleman, to sit in the kirk puffing tobacco-reek, as if he were in a change-house." The date of the incident was 1737; but whether Sir Walter had any authority in fact for this characteristic performance of Knockdunder, or not, it is certain that any such occurrence in a Scottish kirk must have been extremely rare.
