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:
Hogarth's subscription ticket for the print of Sigismunda was Time smoking a Picture (1761). It represents an old man sitting on a fragment of statuary and smoking a long pipe against a picture of a landscape which stands upon an easel before him. Below, on his left, is a large jar labelled "Varnish." The figure of Time is nude and has large wings. Volumes of smoke are pouring against the surface of the picture from both his mouth and the bowl of his long clay pipe. In The Stage-Coach, or Country Inn-yard, is shown an old woman smoking a pipe in the "basket" of the coach. The plate of The Distrest Poet (1736) shows four books and three tobacco-pipes on a shelf. In the second of the "Election" series—the Canvassing for Votes (1755)—a barber and a cobbler, seated at the table in the right-hand corner, are both smoking long pipes. Apparently they are discussing the taking of Portobello by Admiral Vernon in 1739 with only six ships; for the barber is illustrating his talk by pointing with his twisted pipe-stem to six fragments which he has broken from the stem and arranged on the table in the shape of a crescent. In the frontispiece which Hogarth drew in 1762 for Garrick's farce of "The Farmer's Return from London," the worthy farmer, seated in his great chair, holds out a large mug in one hand to be filled with ale, while the other supports his long pipe, which he is smoking with evident enjoyment.
