RADIO BROADCAST
gineering, with the possible exception of aviation, that has so rapidly developed. The Navy has its wig-wag signals, of course. When its ships are in sight of one another it flashes signals by the blinkers or the heliograph, using a searchlight perhaps. It has its red and white vertical signals too. But when the distance is worth noticing, and frequently at other times, radio is the thing! You'd think the air would be gummed with all this sending and receiving, but system is the word. It has to be so. For radio is now as much a part of the every-day.
Langley Field to sink the target — and promptly sank it. Meanwhile, another flock started from its base, a hundred miles away. Then, out from the radio guard ship that day, snapped the order to the leader of this second flock of planes, "Target sunk. Return to base." The leader got the message, barked his orders into a radiophone, and in perfect order his planes turned back. Again, one day, while the experiments were on, the Shawmut caught a message from Langley to the planes, " Drop your bombs and return to base. Storm coming up

THE NAVY S INTERNATIONAL RADIO SERVICE Over the routes shown in this map the Navy handles news and connmercia! messages as well as its own departmental and other Government matter
every-hour, every-minute routine of the Fleet as the use of engines and rudders. Not only for emergencies, not only for maneuvres, not only for all sorts of general utility work does the Navy use radio; rather, the Navy is simply run by radio. The Secretary of the Navy, let us say, wants to send word via an all-Navy radiogram to all the 650 naval ship stations, all the 102 naval airplane stations, all the 180 shore radio telegraph stations? Very well, he dictates his message, in a trice someone snatches it, in code, down the corridor, and, pronto! it is leaping tell-tale up and down and round the world. And it's just about as easy for him to reach the 1,037 Shipping Board stations and every other thing, almost, that floats. Or, say, you have an event like the bombing experiments in Chesapeake Bay last year. There, one day, a flock of bombers set out from
the Coast." And again, one afternoon, when a bomber was circling overhead, waiting for the inspecting officials to leave the target, it flashed its message down to the radio, guard ship, the Shawmut, "Unless you leave the target within fifteen minutes we must return to base because our gas is running low." They left!
But such bits of administration as these are commonplace to the Navy. It has a good deal more than $25,000,000 invested in radio. It is sending a good deal more than 8,000,000 words a month by radio. It is doing ^10,000,000 worth of commercial radio business annually—business at the rates of the commercial companies which they themselves cannot handle. Yet the important thought is this: That our Navy has without question the most comprehensive and effective net of its trans
