The aerial was there, towering as serenely against the slaty sky as though there was no such thing as a snowstorm. The great marvel of radio! For no wires, other than the antenna, were needed to carry its messages to the farthermost parts of the world!

For a moment the boys were awed as the real significance of the modern miracle was borne home to them. It was magnificent, it was inspiring merely to have the privilege of living in such an age.

“Well, Mr. Salper doesn’t need to worry,” said Joe, at last. “There’s always radio on the job if he wants to get a quick message through to New York.”

“It’s queer he didn’t think of it,” agreed Bob, adding, as the intense cold struck still more deeply into his bones: “Come on in, fellows. I’d like to see what the operator has to say to all this excitement.”

“You bet,” said Jimmy, adding fervently: “And it will give us a chance to thaw out.”

When the boys reached the room which had become so familiar to them, they found that here too, the old régime had been interrupted. Several men were gathered in the far corner of the room, talking earnestly, and the long table where the operator could be seen daily bending earnestly over his beloved apparatus was vacant. The operator himself was nowhere to be seen.

Sensing something unusual, the boys came forward hesitantly. At sight of them one of the men detached himself from the group of his companions and came quickly over to them. The boys did not know his name, but his face was familiar to them.

“A most unfortunate thing has happened,” burst out this man nervously, without even an attempt at a preface. “The operator here has been taken very ill with a fever and we are at a loss to find any one who can take his place in this emergency.”

The modesty of the radio boys was such that at that moment no thought of the possibility of their being able to take the experienced operator’s place entered their heads. They were earnestly sorry for the misfortune which had overtaken their friend, and they told the man so. It seemed to them that the latter was rather disappointed about something, and he listened to their words of sympathy absently. After a moment he left them and rejoined his companions at the other end of the room.

“Say, that’s tough luck,” said Jimmy, his round face comically long. “I knew that fellow would get into trouble if he didn’t take more exercise.”
