From Chapter 4:
There is a curious entry in Thomas Burton's diary of the proceedings of Cromwell's Parliament, which suggests that there may then have been the luxury of a members' smoking-room. Burton was a member of the Parliaments of Oliver and Richard Cromwell from 1656 to 1659, and made a practice—for which historical students have been and are much his debtors—of taking notes of the debates as he sat in the House. Members sometimes objected to and protested against this note-taking, but Burton quietly went on using his pencil, and though his summaries of speeches are often difficult to follow, argument and sense suffering by compression, he has preserved much very valuable matter. Referring to a debate on January 7, 1656-57, on an attempt to go behind the previously passed Act of Oblivion, the diarist records that "Sir John Reynolds had numbered the House, and said at rising there were 220 at the least, besides tobacconists." This can only mean that there were at least 220 members actually present in the House when it rose, not counting the "tobacconists" or smokers, who were enjoying their pipes, not in the Chamber itself, but in some conveniently adjoining place, which may have been a room for the purpose, or may simply have been the lobby referred to above in the extract from "Mercurius Pragmaticus."

From Chapter 7:
The antiquary Hearne has left on record an account of a curious smoking match held at Oxford in 1723. It began at two o'clock in the afternoon of September 4 on a scaffold specially erected for the purpose "over against the Theatre in Oxford ... just at Finmore's, an alehouse." The conditions were that any one (man or woman) who could smoke out three ounces of tobacco first, without drinking or going off the stage, should have 12s. "Many tryed," continues Hearne, "and 'twas thought that a journeyman taylour of St. Peter's in the East would have been victor, he smoking faster than, and being many pipes before, the rest: but at last he was so sick, that 'twas thought he would have dyed; and an old man, that had been a souldier, and smoaked gently, came off conqueror, smoaking the three ounces quite out, and he told one (from whom I had it) that, after it, he smoaked 4 or 5 pipes the same evening." The old soldier was a well-seasoned veteran.
