From Chapter 1:
Perhaps the most likely scene of Raleigh's first experiments in the art of smoking was Durham House, which stood where the Adelphi Terrace and the streets between it and the Strand now stand. This was in the occupation of Sir Walter for twenty years (1583-1603), and he was probably resident there when Hariot returned from Virginia to make his report and instruct his employer in the management of a pipe. Walter Thornbury, in his "Haunted London," referring to the story of the servant throwing the ale over his smoking master, says: "There is a doubtful old legend about Raleigh's first pipe, the scene of which may be not unfairly laid at Durham House, where Raleigh lived." The ale story is mythical, but it is highly probable that Sir Walter's first pipes were smoked in Durham House. Dr. Brushfield quotes Hepworth Dixon, in "Her Majesty's Tower," as drawing "an imaginary and yet probable picture of him and his companions at a window of this very house, overlooking the 'silent highway':

From Chapter 8:
Notwithstanding the unfashionableness of tobacco, there were still some noteworthy smokers to be found among the clergy. Dr. Sumner, head master of Harrow, who died in 1771, was devoted to his pipe. The greatest of clerical "tobacconists" of late eighteenth century and early nineteenth century date was the once famous Dr. Parr. It was from him that Dr. Sumner learned to smoke. When he and Parr got together Sumner was in the habit of refilling his pipe again and again in such a way as to be unobserved, at the same time begging Parr not to depart till he had finished his pipe, in order that he might detain him, we are told, in the evening as long as possible.
