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 5:
These seventeenth-century pipes were largely made in Holland of pipe-clay imported from England—to the disgust and loss of English pipe-makers. In 1663 the Company of tobacco-Pipe Makers petitioned Parliament "to forbid the export of tobacco pipe clay, since by the manufacture of pipes in Holland their trade is much damaged." Further, they asked for "the confirmation of their charter of government so as to empower them to regulate abuses, as many persons engage in the trade without licence." The Company's request was granted; but in the next year they again found it necessary to come to Parliament, showing "the great improvement in their trade since their incorporation, 17 James I, and their threatened ruin because cooks, bakers, and ale-house keepers and others make pipes, but so unskilfully that they are brought into disesteem; they request to be comprehended in the Statute of Labourers of 5 Elizabeth, so that none may follow the trade who have not been apprentices seven years."
