all quarters at the receiving-station are automatically transferred to wire lines and received in audible tones at the central office. The action is simultaneous, from the time the signals are transmitted from some foreign point and picked up by the aërial, to the moment when the receiving operator in New York transcribes them.

We can realize the significance of this when we remember that in the early days of the art each station functioned alternately as a transmitter, a receiver, and a telegraphoffice, which, of course, involved a great loss of time and a consequent reduction of possible business, since the station had to stop sending while receiving, and vice versa. When the signals reach the central office they are interpreted and typed off by skilled operators, or else received automatically at high speed by ink recorders. Lastly, they are handed to messenger-boys, who bear them to all parts of the city.

Each antenna consists of sixteen silicon-bronze cables three eighths of an inch in diameter. For the first two antenna systems,-those already erected,-fifty miles of cable were needed. The ground system for these consists of 450 miles of copper wire, which is buried in the ground in "starfish” and in "gridiron” fashion.

The first power-house section accommodates two 200-Kilowatt high-frequency transmitting alternators with their auxiliaries and equipment. Each transmitting unit has a sending speed of one hundred words a minute, so that the two units already completed have a combined sending capacity of two hundred words per minute. As new antenna units are added the transmitting capacity will be correspondingly increased.

One of the picturesque features at the great transmitting-station is the cooling-pond, where the water which circulates through the high-speed alternators is cooled. This pond is seven feet deep and 64 by 42 feet in area.

It is provided with four spray-heads, which send graceful and ornamental jets of water into the air. The 23,000-volt transmission-line which sup

Ned and Laurie Turner, twins, arrive at Hillman's School at Orstead, N. Y., from their home in California. They consider that, although inexperienced, they owe it to the school to go in for sports, and it is decided that Ned shall take up football, and Laurie, baseball. Their first acquaintance among their fellows is a neighbor on their floor named "Kewpie" Proudtree, Kewpie, a candidate for center on the football team, has, contrary to orders, taken on flesh in the course of a lazy summer and seeks to placate the captain by introducing Ned as a star player. Laurie aids in the hoax, and Ned, whose igno rance of football is colossal, is welcomed as a valuable addition to the squad. He threatens mutiny, but Laurie convinces him that the honor of the Turners is at stake and that he must go on with it.
