The minute-hand is seventeen feet from end to end, and twelve feet from center to point, while the hour-hand measures thirteen feet four inches in all, and eight feet four inches from the center of the dial outward. These immense hands are of iron framework, sheathed in copper, and weigh 1000 and 700 pounds respectively.

The big clock and the ninety-nine other clocks in the building are regulated from a master clock in the Director’s Room, on the second floor, which sends out minute impulses, and is adjusted to run within five seconds per month.

At night, the dial, hands, and numerals are beautifully illuminated, of which we present a picture, the enlarged minute-hand showing the length of exposure. The time is also flashed all night in a novel manner from the great gilded “lantern” at the apex of the tower, 696 feet above the pavement. The quarter-hours are announced from each of the four faces of the lantern by a single red light, the halves by two red flashes, the three quarters by three flashes. On the hour, the white arc-lights are ‘extinguished temporarily, and white flashes show the number of the hour.

This takes the place of the bells operated in the daytime. They are in four tones, G (1500 pounds), F (2000 pounds), E flat (3000 pounds), and B flat (7000 pounds), and each quarter-hour ring out the “Westminster Chimes,” in successive bars. These are the highest chimes in the world, being situated on the forty-second floor, 615 feet above the street level; and they attract much attention from visitors.
