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 7:
The most famous of country clergymen of the early Georgian period is, of course, Fielding's lovable and immortal Parson Adams. Throughout "Joseph Andrews" the parson smokes at every opportunity. At his first appearance on the scene, in the inn kitchen, he calls for a pipe of tobacco before taking his place at the fireside. The next morning, when he fails to obtain a desired loan from the landlord, Adams, extremely dejected at his disappointment, immediately applies to his pipe, "his constant friend and comfort in his affliction," and leans over the rails of the gallery overlooking the inn-yard, devoting himself to meditation, "assisted by the inspiring fumes of tobacco." Later on, in the parlour of the country Justice of the Peace, who condemned his prisoners before he had taken the depositions of the witnesses against them, and who, by the way, also lit his pipe while his clerk performed this necessary duty, Adams, when his character has been cleared, sits down with the company and takes a cheerful glass and applies himself vigorously to smoking. A few hours later, when the parson, Fanny, and their guide are driven by a storm of rain to take shelter in a wayside ale-house, Adams "immediately procured himself a good fire, a toast and ale, and a pipe, and began to smoke with great content, utterly forgetting everything that had happened." In the same inn, after Mrs. Slipslop has appeared and disappeared, Adams smokes three pipes and takes "a comfortable nap in a great chair," so leaving the lovers, Joseph and Fanny, to enjoy a delightful time together.
