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:
smoking had certainly not died out at Cambridge, even at the time when Denison was at Oxford. According to the "Gradus ad Cantabrigium," 1824, the Cambridge smart man's habit was to dine in the evening "at his own rooms, or at those of a friend, and afterwards blows a cloud, puffs at a segar, and drinks copiously." The spelling of "segar" shows that cigars were then somewhat of a novelty.
