Connected with these buildings are store-houses, a room for the master and crew of the attending vessels, and a signal-tower fifty feet high, at the top of which is a small observatory furnished with an excellent achromatic telescope, a flag-staff, and a copper signal-ball measuring eighteen feet in diameter.
To remove as much chance of error as possible, safety signalling methods have been devised to warn the engineer of danger ahead. Many modern railroads are divided into short sections or "blocks," each of which is presided over by a signal-tower. At the beginning of each block stand poles with projecting arms that are connected with the signal-tower by wires running over pulleys.
Stuart reached Hyattstown at daylight on the 12th, having marched sixty-five miles in twenty hours. The abundance of captured horses enabled him to make rapid changes for the guns and caissons and to continue the march without delay. Two miles from Hyattstown the road entered a large piece of woodland, which served to conceal his movements from observation from any signal-tower.
Each section of the city has a signal-tower of this sort, and the engine-house is close at hand. Naturally, in a city which lies on a level with the southern point of Greenland, the most characteristic season to select for our observations of the life is winter. The Prospekt wakes late.
