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:
A Sussex rector, the Rev. Giles Moore, of Horsted Keynes, in 1656 and again in 1662, paid 1s. for two ounces of tobacco, i.e. at the rate of 8s. per lb. Presumably the rector bought the more expensive Spanish tobacco and the squire the cheaper Virginian. At the annual parish feast held at St. Bride's, Fleet Street, London, on May 24, 1666, the expenses included 3d. for tobacco for twenty or more adults. This too was doubtless Virginian or colonial tobacco. The North Elmham Church Accounts (Norfolk) for 1673 show that 12s. 4 d. was paid for "Butter, cheese, Bread, Cakes, Beere and Tobacco and Tobacco Pipes at the goeing of the Rounds of the Towne." On the occasion of a similar perambulation of the parish boundaries in 1714-15 the churchwardens paid for beer, pipes and tobacco, cakes and wine. The account-books of the church and parish of St. Stephen, Norwich, for 1696-97 show 2s. as the price of a pound of tobacco. These entries, and many others of similar import, show that at feasts and at social and convivial gatherings of all kinds, tobacco maintained its ascendancy. Pipes and tobacco were included in the usual provision for city feasts, mayoral and other; and smoking was made a particular feature of the Lord Mayor's Show of 1672. A contemporary pamphleteer says that in the Show of that year were "two extreme great giants, each of them at least 15 foot high, that do sit, and are drawn by horses in two several chariots, moving, talking, and taking tobacco as they ride along, to the great admiration and delight of all the spectators." Among the guests at a wedding in London in 1683 were the Lord Mayor, Sheriff and Aldermen of the City, the Lord Chief Justice—the afterwards notorious Jeffreys—and other "bigwigs." Evelyn records with grave disapproval that "these great men spent the rest of the afternoon till 11 at night, in drinking healths, taking tobacco, and talking much beneath the gravity of judges, who had but a day or two before condemned Mr. Algernon Sidney."
