From Chapter 1:
Various places are traditionally associated with Raleigh's first pipe. The most surprising claim, perhaps, is that of Penzance, for which there is really no evidence at all. Miss Courtney, writing in the Folk-Lore Journal, 1887, says: "There is a myth that Sir Walter Raleigh landed at Penzance Quay when he returned from Virginia, and on it smoked the first tobacco ever seen in England, but for this I do not believe that there is the slightest foundation. Several western ports, both in Devon and Cornwall, make the same boast." Miss Courtney might have added that Sir Walter never himself visited Virginia at all.

From Chapter 8:
In the whole sixteen volumes of Walpole's correspondence, as so admirably edited by Mrs. Toynbee, there is scarcely a mention of tobacco; and the same may be said of other collections of letters of the same period—the Selwyn letters, the Delany correspondence, and so on. Neither Walpole nor any member of the world in which he lived would appear to have smoked. In Miss Burney's "Evelina," 1778, from the beginning to the end of the book there is no mention whatever of tobacco or of smoking. Apparently the vulgar Branghtons were not vulgar enough to smoke. Such use of tobacco was considered low, and was confined to the classes of society indicated in the preceding chapter. One of the characters in Macklin's "Love à la Mode," 1760, is described as "dull, dull as an alderman, after six pounds of turtle, four bottles of port, and twelve pipes of tobacco."
