From Chapter 1:
Another tradition gives the old Pied Bull at Islington, long since demolished, as the scene of the momentous event. It is said in its earlier days to have been a country house of Sir Walter's, and according to legend it was in his dining-room in this house that he had his first pipe. Hone, in the first volume of the "Every Day Book" tells how he and some friends visited this Pied Bull, then in a very decayed condition, and smoked their pipes in the dining-room in memory of Sir Walter. From the recently published biography of William Hone by Mr. F.W. Hackwood, we learn that the jovial party consisted of William Hone, George Cruikshank, Joseph Goodyear, and David Sage, who jointly signed a humorous memorandum of their proceedings on the occasion, from which it appears that "each of us smoked a pipe, that is to say, each of us one or more pipes, or less than one pipe, and the undersigned George Cruikshank having smoked pipes innumerable or more or less," and that "several pots of porter, in aid of the said smoking," were consumed, followed by bowls of negus made from "port wine @ 3s. 6d. per bottle (duty knocked off lately)" and other ingredients. Speeches were made and toasts proposed, and altogether the four, who desired to "have the gratification of saying hereafter that we had smoked a pipe in the same room that the man who first introduced tobacco smoked in himself," seem to have thoroughly enjoyed themselves.

From Chapter 7:
Throughout the eighteenth century the use of tobacco for smoking was largely confined to the middle and humbler classes of society. To smoke was characteristic of the "cit," of the country squire, of the clergy (especially of the country parsons), and of those of lower social status. But at the same time it must be borne in mind that then, as since, the dictates of fashion and the conventions of society were little regarded by many artists and men of letters.

In the preceding chapter I quoted from Addison's diary of a retired tradesman in the Spectator of 1712. The periodical publications of a generation or so later paid the great essayist the flattery of imitation in this respect as in others. In the Connoisseur of George Colman and Bonnell Thornton, for instance, there is, in 1754, the description of a citizen's Sunday. The good man, having sent his family to church in the morning, goes off himself to Mother Redcap's, a favourite tavern—suburban in those days—or house of call for City tradesmen. There he smokes half a pipe and drinks a pint of ale. In the evening at another tavern he smokes a pipe and drinks two pints of cider, winding up the inane day at his club, where he smokes three pipes before coming home at twelve to go to bed and sleep soundly.
