From Chapter 2:
Hentzner, the German traveller, who visited London in 1598, speaks of smoking being customary among the audience at plays, who were also supplied with "fruits, such as apples, pears and nuts, according to the season, carried about to be sold, as well as ale and wine." He was struck with the universal prevalence of the tobacco-habit. Not only at plays, but "everywhere else," he says, the "English are constantly smoking tobacco," and then he proceeds to describe how they did it: "They have pipes on purpose made of clay, into the further end of which they put the herb, so dry that it may be rubbed into powder; and putting fire to it, they draw the smoak into their mouths, which they puff out again through their nostrils, like funnels, along with it plenty of phlegm and defluxions from the head." This suggests that the unpleasant and quite unnecessary habit of spitting was common with these early smokers, a suggestion which is amply supported by other contemporary evidence.

From Chapter 5:
The French traveller, Sorbière, who visited London in 1663, declared that the English were naturally lazy and spent half their time in taking tobacco. They smoked after meals, he observed, and conversed for a long time. "There is scarce a day passes," he wrote, "but a Tradesman goes to the Ale-house or Tavern to smoke with some of his Friends, and therefore Public Houses are numerous here, and Business goes on but slowly in the Shops"; but, curiously enough, he makes no mention of coffee-houses. A little later they were too common and too much frequented to be overlooked. An English writer on thrift in 1676 said that it was customary for a "mechanic tradesman" to go to the coffee-house or ale-house in the morning to drink his morning's draught, and there he would spend twopence and consume an hour in smoking and talking, spending several hours of the evening in similar fashion.
