From Chapter 2:
Sir Francis Vere, in the account of his services by sea and land which he wrote about 1606, mentions that on an expedition to the Azores in 1597, the Earl of Essex, waiting for news of the enemy at St. Michael, "called for tobacco ... and so on horseback, with those Noblemen and Gentlemen on foot beside him, took tobacco, whilst I was telling his Lordship of the men I had sent forth, and orders I had given." Presently came the sound of guns, which "made his Lordship cast his pipe from him, and listen to the shooting."

From Chapter 8:
In the whole sixteen volumes of Walpole's correspondence, as so admirably edited by Mrs. Toynbee, there is scarcely a mention of tobacco; and the same may be said of other collections of letters of the same period—the Selwyn letters, the Delany correspondence, and so on. Neither Walpole nor any member of the world in which he lived would appear to have smoked. In Miss Burney's "Evelina," 1778, from the beginning to the end of the book there is no mention whatever of tobacco or of smoking. Apparently the vulgar Branghtons were not vulgar enough to smoke. Such use of tobacco was considered low, and was confined to the classes of society indicated in the preceding chapter. One of the characters in Macklin's "Love à la Mode," 1760, is described as "dull, dull as an alderman, after six pounds of turtle, four bottles of port, and twelve pipes of tobacco."
