From Chapter 1:
The truth probably is that whoever actually smoked the first pipe, it was Raleigh who brought the practice into common use. It is highly probable, also, that Raleigh was initiated in the art of smoking by Thomas Hariot. This was made clear, I think, by the late Dr. Brushfield in the second of the valuable papers on matters connected with the life and achievements of Sir Walter, which he contributed under the title of "Raleghana" to the "Transactions" of the Devonshire Association. Hariot was sent out by Raleigh for the specific purpose of inquiring into and reporting upon the natural productions of Virginia. He returned in 1586, and in 1588 published the results of his researches in a thin quarto with an extremely long-winded title beginning "A briefe and true report of the new found land of Virginia" and continuing for a further 138 words.

From Chapter 6:
Sir Roger de Coverley, as a typical country squire, was naturally a smoker. He presented his friend the Spectator, the silent gentleman, with a tobacco-stopper made by Will Wimble, telling him that Will had been busy all the early part of the winter in turning great quantities of them, and had made a present of one to every gentleman in the county who had good principles and smoked. When Sir Roger was driving in a hackney-coach he called upon the coachman to stop, and when the man came to the window asked him if he smoked. While Sir Roger's companion was wondering "what this would end in," the knight bid his Jehu to "stop by the way at any good Tobacconist's, and take in a Roll of their best Virginia." And when he visited Squire's near Gray's Inn Gate, his first act was to call for a clean pipe, a paper of tobacco, a dish of coffee, a newspaper and a wax candle; and all the boys in the coffee-room ran to serve him. The wax candle was of course a convenience in matchless days for pipe-lighting. The "paper of tobacco" was the equivalent of what is now vulgarly called a "screw" of tobacco.
