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:
John Philips, the author of "Cyder" and the "Splendid Shilling," was an undergraduate at Christ Church, during Aldrich's term of office, and no doubt learned to smoke in an atmosphere so favourable to tobacco. In his "Splendid Shilling," which dates from about 1700, Philips says of the happy man with a shilling in his pocket:

Meanwhile, he smokes, and laughs at merry tale,
Or Pun ambiguous or Conundrum quaint.
But the poor shillingless wretch can only
doze at home
In garret vile, and with a warming puff
Regale chill'd fingers; or from tube as black
As winter-chimney, or well-polish'd jet,
Exhale Mundungus, ill-perfuming scent.
>The miserable creature, though without a shilling, yet possessed a well-coloured "clay."

It is significant that the writer of a life of Philips, which was prefixed to an edition of his poems which was published in 1762, after mentioning that smoking was common at Oxford in the days of Aldrich, says apologetically, "It is no wonder therefore that he [Philips] fell in with the general taste ... he has descended to sing its praises in more than one place." By 1762, as we shall see, smoking was quite unfashionable, and consequently it was necessary to explain how it was that a poet could "descend" so low as to sing the praises of tobacco.
