From Chapter 3:
It is uncertain when licences were first issued for the sale of tobacco. Probably they were issued in London some time before it was considered necessary to license dealers in other parts of the country. Among the Municipal Records of Exeter is the following note: "358. Whitehall, 31 August 1633. The Lords of the Council to the Chamber. 'Whereas his Ma^tie to prevent the excesse of the use of tobacco, and to set an order to those that regrate and sell or utter it by retayle, who observe noe reasonable rates or prizes [prices], nor take care that it be wholsome for men's bodyes that shall use it,' has caused letters to be sent to the chief Officers of Citties and towns requiring them to certify 'in what places it might be fitt to suffer ye retayleing of tobacco and how many be licenced in each of those places to use trade'; and the City of Exeter having made a return the Lords sent a list of those which are to be licensed, and order that no others be permitted to sell."

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."
