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 7:
Fielding himself smoked his pipe. When his play "The Wedding Day" was produced by Garrick in 1743, various suggestions were made to the author as to the excision of certain passages, and the modification of one of the scenes. Garrick pressed for certain omissions, but—"No, damn them," said Fielding, "if the scene is not a good one, let them find that out"; and then, according to Murphy, he retired to the green-room, where, during the progress of the play, he smoked his pipe and drank champagne. Presently he heard the sound of hissing, and when Garrick came in and explained that the audience had hissed the scene he had wished to have modified, all Fielding said was: "Oh, damn them, they have found it out, have they!"

Simon Fraser, Lord Lovat, the crafty old Jacobite who took part in the rising of 1745 and who was executed on Tower Hill in 1747, was a smoker. The pipe which he was reported to have smoked on the evening before his execution, together with his snuff-box and a canvas tobacco-bag, were for many years in the possession of the Society of Cogers, the famous debating society of Fleet Street.
