From Chapter 4:
One inference at least may be fairly drawn, I think, from this document, and that is that smoking was very popular north as well as south of the Tweed.

Tobacco was certainly cheap in Scotland. The following entries are from a MS. account of household expenses kept by the minister of the parish of Eastwood, near Glasgow, the Rev. William Hamilton. They cover two months only and show that the minister was a furious smoker. The prices given are in Scots currency, the pound Scots being worth about twenty pence sterling:

It may perhaps be interesting to compare with these prices, from which, apparently, it may be inferred that near Glasgow tobacco could be bought for some 5d. a pound, which seems incredibly cheap, the occasional expenditure upon tobacco of a worthy citizen of Exeter some few years earlier. Extracts from the "Financial Diary" of this good man, whose name was John Hayne, and who was an extensive dealer in serges and woollen goods generally, as well as in a smaller degree of cotton goods also, were printed some years ago, with copious annotations, by the late Dr. Brushfield.

From Chapter 8:
A satirical print by Rowlandson contains A Man of Fashion's Journal, dated May 1, 1802. The "man of fashion" rides and drinks, goes to the play, gambles and bets, but his journal contains no reference to smoking. Rowlandson himself smoked, and so did his brother caricaturist, Gillray. Angelo says that they would sometimes meet at such resorts of the "low" as the Bell, the Coal Hole, or the Coach and Horses, and would enter into the common chat of the room, smoke and drink together, and then "sometimes early, sometimes late, shake hands at the door—look up at the stars, say it is a pretty night, and depart, one for the Adelphi, the other to St. James's Street, each to his bachelor's bed."

But outside the fashionable world pipes were still in full blast, and in many places of resort the atmosphere was as beclouded with tobacco-smoke as in earlier days. Grosley, in his "Tour to London," 1765, says that there were regular clubs, which were held in coffee-houses and taverns at fixed days and hours, when wine, beer, tea, pipes and tobacco helped to amuse the company.
