From Chapter 1:
In this "Report" Hariot says of the tobacco plant: "There is an herbe which is sowed a part by itselfe and is called by the inhabitants Vppówoc: In the West Indies it hath divers names, according to the severall places and countries where it groweth and is used: The Spaniardes generally call it Tobacco. The leaves thereof being dried and brought into powder: they use to take the fume or smoke thereof by sucking it through pipes made of claie into their stomacke and heade: from whence it purgeth superfluous fleame and other grosse humors, openeth all the pores and passages of the body: by which meanes the use thereof, not only preserveth the body from obstructions: but if also any be, so that they have not beane of too long continuance, in short time breaketh them: wherby their bodies are notably preserved in health, and know not many greevous diseases wherewithall wee in England are oftentimes afflicted."

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."
