From Chapter 1:
In the Wallace Collection at Hertford House is a pouch or case labelled as having belonged to and been used by Sir Walter Raleigh. This pouch contains several clay pipes. It was perhaps this same pouch or case which once upon a time figured in Ralph Thoresby's museum at Leeds, and is described by Thoresby himself in his "Ducatus Leodiensis," 1715. Curiously enough, a few years ago when excavations were being made around the foundations of Raleigh's house at Youghal a clay pipe-bowl was dug up which in size, shape, &c., was exactly like the pipes in the Wallace exhibit. Raleigh lived and no doubt smoked in the Youghal house, so it is quite possible that the bowl found belonged to one of the pipes actually smoked by him. In the garden of the Youghal house, by the way, they used to show the tree—perhaps still do so—under which Raleigh was sitting, smoking his pipe, when his servant drenched him. Thus the tradition, which, as we have seen, dates from 1708 only, has obtained two local habitations—Youghal and Durham House on the Adelphi site.

From Chapter 8:
In the first two or three decades of the nineteenth century smoking reached its nadir. No dandy smoked. If some witnesses may be believed smoking had almost died out even at Oxford. Archdeacon Denison wrote in his "Memories"—"When I went up to Oxford, 1823-24, there were two things unknown in Christ Church, and I believe very generally in Oxford—smoking and slang"; but one cannot help fancying that the archdeacon's memory was not quite trustworthy. It is difficult to imagine that there was ever a time when the slang of the day was not current on the lips of young Oxford, or that so long as tobacco was procurable it did not find its way into college rooms.
