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:
smoking was frowned upon, even in places where hitherto it had been allowed. In 1812 the authorities of Sion College ordered "that Coffee and Tea be provided in the Parlour for the Visitors and Incumbents, and in the Court Room for the Curates and Lecturers; and that Pipes and Tobacco be not allowed; and that no Wine be at any time carried into the Court Room, nor any into the Hall after Coffee and Tea shall have been ordered on that day."

The use of tobacco for smoking, as I have said, had reached its nadir—in the fashionable world, that is to say—but the dawn follows the darkest hour, and the revival of smoking was at hand, thanks to the cigar.
