From Chapter 2:
The rich young gallant carried about with him his tobacco apparatus (often of gold or silver) in the form of tobacco-box, tobacco-tongs—wherewith to lift a live coal to light his pipe, ladle "for the cold snuffe into the nosthrill," and priming-iron. Sometimes the tobacco-box was of ivory; and occasionally a gallant would have looking-glass set in his box, so that when he took it out to obtain tobacco, he could at the same time have a view of his own delectable person. When our gallant went to dine at the ordinary, according to the custom of the time, he brought out these possessions, and smoked while the dinner was being served. Before dinner, after taking a few turns up and down Paul's Walk in the old cathedral, he might look into the booksellers' shops, and, pipe in mouth, inquire for the most recent attack upon the "divine weed"—the contemporary tobacco literature was abundant—or drop into an apothecary's, which was usually a tobacco-shop also, and there meet his fellow-smokers.

From Chapter 5:
When plague was abroad even children were compelled to smoke. At the time of the dreadful visitation of 1665 all the boys at Eton were obliged to smoke in school every morning. One of these juvenile smokers, a certain Tom Rogers, years afterwards declared to Hearne, the Oxford antiquary, that he never was whipped so much in his life as he was one morning for not smoking. Times have changed at Eton since this anti-tobacconist martyr received his whipping. It is sometimes stated that at this time smoking was generally practised in schools, and that at a stated hour each morning lessons were laid aside, and masters and scholars alike produced their pipes and proceeded to smoke tobacco. But I know of no authority for this wider statement; it seems to have grown out of Hearne's record of the practice at Eton.
