From Chapter 1:
"'It requires no effort of the fancy to picture these three men [Shakespeare, Bacon and Raleigh] as lounging in a window of Durham House, puffing the new Indian weed from silver bowls, discussing the highest themes in poetry and science, while gazing on the flower-beds and the river, the darting barges of dame and cavalier, and the distant pavilions of Paris garden and the Globe.'" This is a pure "effort of the fancy" so far as Bacon and Shakespeare are concerned. Shakespeare's absolute silence about tobacco forbids us to assume that he smoked; but of Raleigh the picture may be true enough. The house had, as Aubrey tells us, "a little turret that looked into and over the Thames, and had the prospect which is as pleasant perhaps as any in the world"; and it would be strange indeed if the owner of the noble house did not often smoke a contemplative pipe in the window of that pleasant turret.

From Chapter 8:
Parr was not a model smoker. He was brutally overbearing towards other folk, and would accept no invitation except on the understanding that he might smoke when and where he liked. It was his invariable practice, wherever he might be visiting, to smoke a pipe as soon as he had got out of bed. His biographer says—"The ladies were obliged to bear his tobacco, or to give up his company; and at Hatton (1786-1825) now and then he was the tyrant of the fireside." Parr was capable of smoking twenty pipes in an evening, and described himself as "rolling volcanic fumes of tobacco to the ceiling" while he worked at his desk. At a dinner which was given at Trinity College, Cambridge, to the Duke of Gloucester, as Chancellor of the University, when the cloth was removed, Parr at once started his pipe and began, says one who was present, "blowing a cloud into the faces of his neighbours, much to their annoyance, and causing royalty to sneeze by the stimulating stench of mundungus." It is surprising that people were willing to put up with such bad manners as Parr was accustomed to exhibit; but his reputation was then great, and he traded upon it.
