For a week the scientists debated—while the world waited in intense and growing anxiety. But the learned men accomplished nothing. They could not even agree. The battle seemed one of man against nature, and man was helpless.

In a gloomy state of mind they began to consider adjournment. At 10 o’clock on the night of the nineteenth of August the question of terminating the sessions was scheduled for a final vote.

That night, as the hands of the clock on the wall above the presiding officer’s head drew near the fateful hour, the tension throughout the assemblage became intensely dramatic. Everyone present knew in his heart that further deliberation was useless, but the fate of the human race seemed to hang upon their decision.

Even after the sound of the clock’s striking had died out upon the stillness of the room, Professor Whiteman remained seated; he seemed haggard and downcast. At last, however, he drew himself up and opened his lips to speak.

At that moment a secretary tiptoed swiftly in and whispered briefly to the presiding officer. Professor Whiteman gave a start and answered something that sent the secretary hurrying out.

Betraying strange emotion, the scientist now addressed the assemblage. His words came haltingly, as if he feared they would be greeted with ridicule.

“Gentlemen,” he said, “a strange thing has happened. A few minutes ago—the wireless signals that have always accompanied the earthquakes ceased abruptly. In their place came—a mysterious summons out of the ether—whence no one knows—demanding a conversation with the presiding officer of this body. The sender of the message declares his communication has to do with the problem we have been trying to solve. Of course—this is probably some hoax—but our operator is greatly excited over the circumstances surrounding the call, and urges that we come to the wireless room at once!”

With one accord, everyone rose and moved forward.

Leading the way to another part of the observatory grounds, Professor Whiteman ushered the company into the operating room of the wireless plant—one of the most powerful in the world.

A little knot of observatory officials already was clustered about the operator, their manner denoting that something unusual had been going on.
