From Chapter 4:
It is certain that the armies of the Parliament were great smokers, for the finds of seventeenth-century pipes on the sites of their camps have been numerous. A considerable number of pipes of the Caroline period, with the usual small elongated bowls, were found in 1902 at Chichester, in the course of excavating the foundations of the Old Swan Inn, East Street, for building the present branch of the London and County Bank.

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."
