From Chapter 9:
The mention of pigtail shows that the House contained pipe- as well as cigar-smokers. A few days later he wrote again to his sisters, but this time from the library, where, he says, "we are in a far better atmosphere than in the smoking-room, whence I wrote to you last week." One wonders why Macaulay, who apparently did not smoke himself, and who, though somewhat more tolerant of tobacco than his father, Zachary Macaulay, evidently did not like the atmosphere of the smoking-room, chose to write there, when the library—where he must surely have felt more at home—was available.

From Chapter 15:The figure was usually made with a snuff mull in his hand—the highlander being always credited with a great love and a great capacity for snuff-taking. But one curious example was furnished, not only with a mull but with a bat-like implement of unknown use. Mr. Arthur Denman, F.S.A., writing in Notes and Queries, April 17, 1909, said: "I have a very neat little, genuine specimen of the old tobacconist's sign of a 42nd Highlander with his 'mull.' It is 3 ft. 6 in. high, and it differs from those usually met with in that under the left arm is an implement almost exactly like a cricket-bat. This bat has a gilt knob to the handle, and on the shoulder of it are three chevrons in gold, without doubt a sergeant's stripes. On the exposed side of the bat is what would appear to represent a loose strip of wood. This strip is nearly one-third of the width of the instrument, and extends up the middle about two-fifths of the length of the body of it. I can only guess that the bat was, at some time, primarily, an emblem of a sergeant's office, and, secondarily, used for the infliction of chastisement on clumsy or disorderly recruits; and perhaps it was equivalent to the Prügel of German armies, with which sergeants drove lagging warriors into the fray. But is there any record of such an accoutrement as being that of a sergeant in the British army? and what was the purpose of the loose strip, unless it was to cause the blow administered to resound as much as to hurt, as does the wand of Harlequin in a booth."
