From Chapter 7:
In a World of 1755 there is a description of a noisy, hearty, drinking, devil-may-care country gentleman, in which it is said, "he makes no scruple to take his pipe and pot at an alehouse with the very dregs of the people." In a Connoisseur of 1754 a fine gentleman from London, making a visit in a country-house, is taking his breakfast with the ladies in the afternoon, when they had their tea, for, says he, "I should infallibly have perished, had I staied in the hall, amidst the jargon of toasts and the fumes of tobacco." When Horace Walpole was staying with his father at his Norfolk country-seat, Houghton, in September 1737, Gray wrote to him from Cambridge: "You are in a confusion of wine, and roaring, and hunting, and tobacco, and, heaven be praised, you too can pretty well bear it." But Gray had no objection to tobacco. He lived at Cambridge, and the dons and residents there (as at Oxford), not to speak of the undergraduates, were as partial to their pipes as the men who went out from among them to become country parsons, and to share the country squire's liking for tobacco. Gray wrote to Warton from Cambridge in April 1749 saying: "Time will settle my conscience, time will reconcile me to this languid companion (ennui); we shall smoke, we shall tipple, we shall doze together"—a striking picture of University life in the sleepy days of the eighteenth century. Gray's testimony by no means stands alone. In November 1730 Roger North wrote to his son Montague, then an undergraduate at Cambridge, saying: "I would be loath you should confirm the scandal charged upon the universities of learning chiefly to smoke and to drink."

From Chapter 10:
Tobacco was always popular in the army; and even the strongest of anti-tobacconists would have felt that there was at least something, if not much, to be said for the abused weed, when in times of campaigning suffering it played so beneficent a part in soothing and comforting weary and wounded men. The period covered by this chapter included both the Crimean War and the Indian Mutiny, and every one knows how the soldiers in the Crimea and in India alike craved for tobacco as for one of the greatest of luxuries, and how even an occasional smoke cheered and encouraged and sustained suffering humanity. The late Dr. Norman Kerr, who was no friend to ordinary, everyday smoking, wrote: "There are occasions, such as in the trenches during military operations, when worn out with exposure and fatigue, or when exhausted by slow starvation with no food in prospect, when a pipe or cigar will be a welcome and valuable friend in need, resting the weary limbs, cheering the fainting heart, allaying the gnawing hunger of the empty stomach."
