It wanted then about three minutes to twelve; and Major Milroy seized the opportunity of explaining what the exhibition was to be, before the exhibition began.
"At the first words, his mind fell back again into its old absorption over the one employment of his life. He turned to Midwinter (who had persisted in talking all the way from the parlor, and who was talking still) without a trace left in his manner of the cool and cutting composure with which he had spoken but a few minutes before. The noisy, familiar man, who had been an ill-bred intruder in the parlor, became a privileged guest in the workshop, for there he possessed the all-atoning social advantage of being new to the performances of the wonderful clock.
"At the first stroke of twelve, Mr. Midwinter," said the major, quite eagerly, "keep your eye on the figure of Time: he will move his scythe, and point it downward to the glass pedestal. You will next see a little printed card appear behind the glass, which will tell you the day of the month and the day of the week. At the last stroke of the clock, Time will lift his scythe again into its former position, and the chimes will ring a peal. The peal will be succeeded by the playing of a tune--the favorite march of my old regiment--and then the final performance of the clock will follow. The sentry-boxes, which you may observe at each side, will both open at the same moment. In one of them you will see the sentinel appear; and from the other a corporal and two privates will march across the platform to relieve the guard, and will then disappear, leaving the new sentinel at his post. I must ask your kind allowances for this last part of the performance. The machinery is a little complicated, and there are defects in it which I am ashamed to say I have not yet succeeded in remedying as I could wish. Sometimes the figures go all wrong, and sometimes they go all right. I hope they may do their best on the occasion of your seeing them for the first time."
As the major, posted near his clock, said the last words, his little audience of three, assembled at the opposite end of the room, saw the hour-hand and the minute-hand on the dial point together to twelve. The first stroke sounded, and Time, true to the signal, moved his scythe. The day of the month and the day of the week announced themselves in print through the glass pedestal next; Midwinter applauding their appearance with a noisy exaggeration of surprise, which Miss Milroy mistook for coarse sarcasm directed at her father's pursuits, and which Allan (seeing that she was offended) attempted to moderate by touching the elbow of his friend. Meanwhile, the performances of the clock went on. At the last stroke of twelve, Time lifted his scythe again, the chimes rang, the march tune of the major's old regiment followed; and the crowning exhibition of the relief of the guard announced itself in a preliminary trembling of the sentry-boxes, and a sudden disappearance of the major at the back of the clock.
