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:
There is ample evidence, apart from Johnson's dictum, that in the latter part of the eighteenth century smoking had "gone out." In Mrs. Climenson's "Passages from the Diaries of Mrs. Lybbe Powys," we hear of a bundle of papers at Hardwick House, near Whitchurch, Oxon, which bears the unvarnished title "Dick's Debts." This Dick was a Captain Richard Powys who had a commission in the Guards, and died at the early age of twenty-six in the year 1768. This list of debts, it appears, gives "the most complete catalogue of the expenses of a dandy of the Court of George II, consisting chiefly of swords, buckles, lace, Valenciennes and point d'Espagne, gold and amber-headed canes, tavern bills and chair hire." But in all the ample detail of Captain Powys's list of extravagances there is nothing directly or indirectly relating to smoking. The beaux of the time did not smoke.
