From Chapter 4:
So far Markham: but according to another account, when Rupert told him that there would be no battle, the Duke betook himself to his coach, "lit his pipe, and making himself very comfortable, fell asleep." The original authority, however, for the whole story is to be found in a paper of notes by Clarendon on the affairs of the North, preserved among his MSS. In this paper Clarendon writes: "The marq. asked the prince what he would do? His highness answered, 'Wee will charge them to-morrow morninge.' My lord asked him whether he were sure the enimy would not fall on them sooner? He answered, 'No'; and the marquisse thereupon going to his coach hard by, and callinge for a pype of tobacco, before he could take it the enimy charged, and instantly all the prince's horse were routed."

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.
