From Chapter 1:
At the fifteenth-century Manor-House at South Wraxall, Wiltshire, the "Raleigh Room" is shown, and visitors are told that according to local tradition it was in this room that Sir Walter smoked his first pipe, when visiting his friend, the owner of the mansion, Sir Henry Long.

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.
