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:
Country gentlemen smoked just as much as town mechanics and tradesmen. In 1688 Hervey, afterwards Earl of Bristol, wrote to Mr. Thomas Cullum, of Hawsted Place, desiring "to be remembered by the witty smoakers of Hawsted." A later Cullum, Sir John, published in 1784 a "History and Antiquities of Hawsted," and in describing Hawsted Place, which was rebuilt about 1570, says that there was a small apartment called the smoking-room—"a name," he says, "it acquired probably soon after it was built; and which it retained with good reason, as long as it stood." I should like to know on what authority Sir John Cullum could have made the assertion that the room was called the smoking-room from so early a date as the end of the sixteenth century. No mention in print of a smoking-room has been found for the purposes of the Oxford Dictionary earlier than 1689. In Shadwell's "Bury Fair" of that date Lady Fantast says to her husband, Mr. Oldwit, who loves to tell of his early meetings with Ben Jonson and other literary heroes of a bygone day, "While all the Beau Monde, as my daughter says, are with us in the drawing-room, you have none but ill-bred, witless drunkards with you in your smoking-room." As Mr. Oldwit himself, in another scene of the same play, says to his friends, "We'll into my smoking-room and sport about a brimmer," there was probably some excuse for his wife's remark. These country smoking-rooms were known in later days as stone-parlours, the floor being flagged for safety's sake; and the "stone-parlour" in many a squire's house was the scene of much conviviality, including, no doubt, abundant smoking.
