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 8:
smoking had certainly not died out at Cambridge, even at the time when Denison was at Oxford. According to the "Gradus ad Cantabrigium," 1824, the Cambridge smart man's habit was to dine in the evening "at his own rooms, or at those of a friend, and afterwards blows a cloud, puffs at a segar, and drinks copiously." The spelling of "segar" shows that cigars were then somewhat of a novelty.
