From Chapter 3:
A further witness to the prevalence of smoking and to the enormous number of tobacco-sellers' shops is Camden, the antiquary. In his "Annales," 1625, he remarks with curious detail that since its introduction—"that Indian plant called Tobacco, or Nicotiana, is growne so frequent in use and of such price, that many, nay, the most part, with an insatiable desire doe take of it, drawing into their mouth the smoke thereof, which is of a strong scent, through a pipe made of earth, and venting of it againe through their nose; some for wantownesse, or rather fashion sake, and other for health sake, insomuch that Tobacco shops are set up in greater number than either Alehouses or Tavernes."

From Chapter 6:
Even children seem to have smoked sometimes in the coffee-houses. Ralph Thoresby, the Leeds antiquary, tells a strange story. He declares that, one evening which he spent with his brother at Garraway's Coffee-house, February 20, 1702, he was surprised to see his brother's "sickly child of three years old fill its pipe of tobacco and smoke it as audfarandly as a man of three score; after that a second and a third pipe without the least concern, as it is said to have done above a year ago." A child of two years of age smoking three pipes in succession is a picture a little difficult to accept as true. As this is the only reference to tobacco in the whole of his "Diary," it is not likely that Thoresby was himself a smoker.
