From Chapter 4:
Gardiner evidently follows this account, for his version of the story is: "Newcastle strolled towards his coach to solace himself with a pipe. Before he had time to take a whiff, the battle had begun." The incident was made the subject of a picture by Ernest Crofts, A.R.A., which was exhibited at the Royal Academy in 1888. It shows the Duke leaning out of his carriage window, with his pipe in his hand.

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.
