It was three minutes past three postmeridian in the operating room of the new Wireless Station recently installed at the United States Naval Observatory at Georgetown. Bill Hood, the afternoon operator, was sitting in his shirt sleeves with his receivers at his ears, smoking a corncob pipe and awaiting a call from the flagship Lincoln of the North Atlantic Patrol with which, somewhere just off Hatteras, he had been in communication a few moments before. The air was quiet.
Hood was a fat man, and so of course good-natured; but he was serious about his work and hated all interfering amateurs. Of late these wireless pests had become particularly obnoxious, as practically everything was sent out in code and they had nothing with which to occupy themselves. But it was a hot day and none of them seemed to be at work. On one side of his desk a tall thermometer indicated that the temperature of the room was 91 degrees Fahrenheit; on the other a big clock, connected with some extraneous mechanism by a complicated system of brass rods and wires, ticked off the minutes and seconds with a peculiar metallic self-consciousness, as if aware of its own importance in being the official timepiece, as far as there was an official timepiece, for the entire United States of America.
Hood from time to time tested his converters and detector, and then resumed his non-official study of the adventures of a great detective who pursued the baffling criminal by the aid of all the latest scientific discoveries. Hood thought it was good stuff, although at the same time he knew, of course, that it was rot. He was a practical man of little imagination, and, though the detective did not interest him particularly, he liked the scientific part of the stories. He was thrifty, of Scotch-Irish descent, and at two minutes past three had never had an adventure in his life. At three minutes past three he began his career as one of the celebrities of the world.
As the minute hand of the official clock dropped into its slot somebody called the Naval Observatory. The call was so faint as to be barely audible, in spite of the fact that Hood's instrument was tuned for a three-thousand-metre wave. Supposing quite naturally that the person calling had a shorter wave, he gradually cut out the inductance of his receiver; but the sound faded out entirely, and he returned to his original inductance and shunted in his condenser, upon which the call immediately increased in volume. Evidently the other chap was using a big wave, bigger than Georgetown.
Hood puckered his brows and looked about him. Lying on a shelf above his instrument was one of the new ballast coils that Henderson had used with the long waves from lightning flashes, and he leaned over and connected the heavy spiral of closely wound wire, throwing it into his circuit. Instantly the telephones spoke so loud that he could hear the shrill cry of the spark even from where the receivers lay beside him on the table. Quickly fastening them to his ears he listened. The sound was clear, sharp, and metallic, and vastly higher in pitch than a ship's call. It couldn't be the Lincoln.
"By gum!" muttered Hood. "That fellow must have a twelve-thousand-metre wave length with fifty kilowatts behind it, sure! There ain't another station in the world but this can pick him up!"
"NAA—NAA—NAA," came the call.
Throwing in his rheostat he sent an "O.K" in reply, and waited expectantly, pencil in hand. A moment more and he dropped his pencil in disgust.
"Just another bug!" he remarked aloud to the thermometer. "Ought to be poisoned! What a whale of a wave length, though!"
