From Chapter 1:
Wherever Raleigh is known to have lived or lodged we are sure to find the tradition flourishing that there he smoked his first pipe. The assertion has been made of his birthplace, Hayes Barton, although it is very doubtful if he ever visited the place after his parents left it, some years before their son had become acquainted with tobacco; and also with more plausibility of his home at Youghal, in the south of Ireland. Froude, in one of his "Short Studies," quotes a legend to the effect that Raleigh smoked on a rock below the Manor House of Greenaway, on the River Dart, which was the home of the first husband of Katherine Champernowne, afterwards Raleigh's wife; and Devonshire guide-books have adopted the story.

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."
