From Chapter 4:
But to turn from this worthy Exeter citizen to more famous names: I do not know of any good evidence as to whether or not Cromwell smoked, although he is said to have taken an occasional pipe while considering the offer of the crown, but John Milton certainly did. The account of how the blind poet passed his days, after his retirement from public office, was first told by his contemporary Richardson, and has since been repeated by all his biographers. His placid day ended early. The poet took his frugal supper at eight o'clock, and at nine, having smoked a pipe and drunk a glass of water, he went to bed. Apparently this modest allowance of a daily evening pipe was the extent of Milton's indulgence in tobacco. He knew nothing of what most smokers regard as the best pipe of the day—the after-breakfast pipe.

From Chapter 5:
The arrival of coffee and the establishment of coffee-houses opened a new field for the victories of tobacco. The first house was opened in St. Michael's Alley, Cornhill, in 1652. Others soon followed, and in a short time the new beverage had captured the town, and coffee-houses had been opened in every direction. They sold many things besides coffee, and served a variety of purposes, but primarily they were temples of talk and good-fellowship. The buzz of conversation and the smoke of tobacco alike filled the rooms which were the forerunners of the club-houses of a much later day.
