From Chapter 2:
The properly accomplished gallant not only professed to be curiously learned in pipes and tobacco, but his knowledge of prices and their fluctuations, of the apothecaries' and other shops where the herb was sold, and of the latest and most fashionable ways of inhaling and exhaling the smoke, was, like Mr. Weller's knowledge of London, "extensive and peculiar." It was knowledge of this kind that gained for a gallant reputation and respect by no means to be acquired by mere scholarship and learning.

From Chapter 6:
Towards the close of the seventeenth century signs may be detected of some waning in the universal popularity of tobacco. There are hints of change in the records of City and other companies. Tobacco had always figured prominently in the provision for trade feasts. In 1651 the Chester Company of Barbers, Surgeons, Wax and Tallow Chandlers—a remarkably comprehensive organization—paid for "Sack beere and Tobacco" at the Talbot on St. Luke's Day, October 18, on the occasion of a dinner given to the Company by one Richard Walker; and similar expenditure was common among both London and provincial Companies. The court-books of the Skinners Company of London show that in preparation for their annual Election Dinner in 1694, the cook appeared before the court and produced a bill of fare which, with some alterations, was agreed to. The butler then appeared and undertook to provide knives, salt, pepper-pots, glasses, sauces, &c., "and everything needfull for £7. and if he gives content then to have £8. he provides all things but pipes, Tobacco, candles and beer"—which apparently fell to the lot of some other caterer.
