From Chapter 3:
Another proof of the extraordinary popularity of the new habit is to be found in the fact that by the seventeenth year of the reign of James I—the arch-enemy of tobacco—that is, by 1620, the Society of tobacco-pipe-makers had become so very numerous and considerable a body that they were incorporated by royal charter, and bore on their shield a tobacco plant in full blossom. The Society's motto was happily chosen—"Let brotherly love continue."

From Chapter 5:
General Monk, to whom Charles II owed so much, is said to have indulged in the unpleasant habit of chewing tobacco, and to have been imitated by others; but the practice can never have been common.
