From Chapter 4:
It is certain that the armies of the Parliament were great smokers, for the finds of seventeenth-century pipes on the sites of their camps have been numerous. A considerable number of pipes of the Caroline period, with the usual small elongated bowls, were found in 1902 at Chichester, in the course of excavating the foundations of the Old Swan Inn, East Street, for building the present branch of the London and County Bank.

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.
