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 8:
Another famous parson, the Rev. John Newton, was a smoker, and so was Cowper's other clerical friend, that learned and able Dissenter, the Rev. William Bull, whose whole mien and bearing were so dignified that on two occasions he was mistaken for a bishop. Cowper appreciated snuff, but did not care for smoking, and when he wrote to Unwin, describing his new-made friend in terms of admiration, he concluded—"Such a man is Mr. Bull. But—he smokes tobacco. Nothing is perfection 'Nihil est ab omni parte beatum.'" Bull, however, was not excessive in his smoking, for his daily allowance was but three pipes. In his garden at Newport Pagnell, Bull showed Cowper a nook in which he had placed a bench, where he said he found it very refreshing to smoke his pipe and meditate. "Here he sits," wrote Cowper, "with his back against one brick wall, and his nose against another, which must, you know, be very refreshing, and greatly assist meditation."
