From Chapter 7:
At Oxford in early Georgian days a profound calm—so far as study was concerned—appears to have prevailed. Little work was done, but much tobacco was smoked. In 1733 a satire was published, violently attacking the Fellows of various colleges. According to this satirist the occupation of the Magdalen Fellow was to
drink, look big,
Smoke much, think little, curse the freeborn Whig—

from which it may not unreasonably be surmised that the author was a Tory; and however little enthusiasm there may have been at Oxford in those days for learning and study, there was plenty of life in political animosities.

Another witness to the dons' love of tobacco is Thomas Warton. In his "Progress of Discontent," written in 1746, he plaintively sang:

Return, ye days when endless pleasure
I found in reading or in leisure!
When calm around the Common Room
I puff'd my daily pipe's perfume!
Rode for a stomach, and inspected,
At annual bottlings, corks selected:
And dined untax'd, untroubled, under
The portrait of our pious Founder!

From Chapter 4:
It is certain that the armies of the Parliament were great smokers, for the finds of seventeenth-century pipes on the sites of their camps have been numerous. A considerable number of pipes of the Caroline period, with the usual small elongated bowls, were found in 1902 at Chichester, in the course of excavating the foundations of the Old Swan Inn, East Street, for building the present branch of the London and County Bank.

From Chapter 15:
The "Tobacco Roll," either alone or in various combinations, was one of the commonest of early tobacconists' signs, and was in constant use for a couple of centuries. It may still be occasionally seen at the present time in the form of the "twist" with alternate brown or black and yellow coils, which up to quite a recent date was a tolerably frequent adornment of tobacconists' shops, but is now rare. This roll represented what was called spun or twist tobacco. Dekker, in James I's time, speaks of roll tobacco. The youngster who mimics the stage-gallants in Jonson's "Cynthia's Revels" as described in Chapter II (ante; page 31), says that he has "three sorts of tobacco in his pocket," which probably means that it was customary to mix for smoking purposes tobacco of the three usual kinds—roll (or pudding), leaf and cane. One would have thought that a representation of the tobacco plant itself would have been a more natural and comprehensive sign than one particular preparation of the herb, yet representations of the plant were rare, while those of the compressed tobacco known as pudding or roll in the form of a "Tobacco Roll," as described above, were very frequently used as signs.

From Chapter 5:
The French traveller, Sorbière, who visited London in 1663, declared that the English were naturally lazy and spent half their time in taking tobacco. They smoked after meals, he observed, and conversed for a long time. "There is scarce a day passes," he wrote, "but a Tradesman goes to the Ale-house or Tavern to smoke with some of his Friends, and therefore Public Houses are numerous here, and Business goes on but slowly in the Shops"; but, curiously enough, he makes no mention of coffee-houses. A little later they were too common and too much frequented to be overlooked. An English writer on thrift in 1676 said that it was customary for a "mechanic tradesman" to go to the coffee-house or ale-house in the morning to drink his morning's draught, and there he would spend twopence and consume an hour in smoking and talking, spending several hours of the evening in similar fashion.
