From Chapter 2:
smoking was soon as common in the country as in London. On Wednesday, April 16, 1621, in the course of a debate in the House of Commons, Sir William Stroud, who seems to have been a worthy disciple of that tobacco-hater, King James I, moved that he "would have tobacco banished wholly out of the kingdom, and that it may not be brought in from any part, nor used amongst us"; and Sir Grey Palmes said "that if tobacco be not banished, it will overthrow 100,000 men in England, for now it is so common that he hath seen ploughmen take it as they are at plough." Perhaps this terrible picture of a ploughman smoking as he followed his lonely furrow did not impress the House so much as Sir Grey evidently thought it would; at all events, tobacco was not banished.

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.
