<g>Mountjoy’s Tower</g>, probably in honour of the nobleman of that name, governor of Tourney in the time of Henry VIII. The walls of this tower are in some places eighteen feet thick, and still command a beautiful prospect, though less extensive than that from the keep. The ramparts between these towers is about twenty feet high and eight feet thick, including a parapet of two feet and a half, which was carried quite round the castle. Under a small building in the castle-yard, adjoining the governor’s house, is <g>The Garrison Well</g>, from which the water is drawn by means of a large windlass-wheel, turned by an ass. On a former occasion this duty was performed [Illustration] during a period of more than forty years by the same animal, which, on account of his services, was long one of the great curiosities of the place. Down the well it is usual to drop a nail, or even a pin, which, after a lapse of three seconds, produces a sound much greater than can be well conceived by those who have not actually heard it. Another experiment is often made in showing this well to strangers--namely, that of letting down, by means of a pulley, a lighted lamp in a wooden basin, which in descending occasions a loud noise, from the resistance of the air, like a hollow wind or distant thunder; and as the lamp floats upon the surface of the water, the compact masonry of the well--which is partly cut through the rock--is distinctly visible. The water furnished by the castle-well is remarkably pure and sparkling; and in instances where it has been carried to India and back, it has still retained its native purity. <g>The Governor’s House</g> (see p. 294) contains several spacious apartments, but now unfurnished, and only inhabited by the cicerone of the castle. Like the additions above mentioned, it is of the Elizabethan epoch, and externally has a rather picturesque appearance--its gables and tall chimneys much resembling buildings of similar date in the Netherlands. At the conclusion of the late war, the garrison consisted of a governor, a lieutenant-governor, a captain, a master gunner, and three assistants. The salary of the governor was twelve hundred pounds, and that of the lieutenant-governor three hundred and sixty-five pounds per annum.
