From Chapter 10:
Notwithstanding that the number of smokers had so largely increased, and was continually increasing, smoking was regarded socially as something of a vice—to be practised in inconvenient places and not too publicly.

There were still plenty of active opponents and denouncers of tobacco. One of the most distinguished was the great Duke of Wellington, who abominated smoking, and was annoyed by the increase of cigar-smoking among officers of the army. In the early 'forties he issued a General Order (No. 577) which contained a paragraph that would have delighted the heart of King James I. It ran thus: "The Commander-in-Chief has been informed, that the practice of smoking, by the use of pipes, cigars, or cheroots, has become prevalent among the Officers of the Army, which is not only in itself a species of intoxication occasioned by the fumes of tobacco, but, undoubtedly, occasions drinking and tippling by those who acquire the habit; and he intreats the Officers commanding Regiments to prevent smoking in the Mess Rooms of their several Regiments, and in the adjoining apartments, and to discourage the practice among the Officers of Junior Rank in their Regiments."

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.
