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:
smoking was still popular also at Oxford. A. D'Anvers, in her "Academia; or the Humours of Oxford," 1691, speaks, indeed, of undergraduates who, when they could not get tobacco, did much as the parson of Thornton is reputed to have done, as already related in Chapter II, i.e. they condescended to smoke fragments of mats. With this may be compared the macaronic lines:
