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 6:
Even the staid Quakers smoked. George Fox's position in regard to tobacco was curious. He did not smoke himself; but on one occasion he was offered a pipe by a jesting youth who thought thereby to shock so saintly a person. Fox says in his "Journal," "I lookt upon him to bee a forwarde bolde lad: and tobacco I did not take: butt ... I saw hee had a flashy empty notion of religion: soe I took his pipe and putt it to my mouth and gave it to him again to stoppe him lest his rude tongue should say I had not unity with ye creation." The incident is curious, but testifies to Fox's tolerance and breadth of outlook.
