“Amazing!” said Dr. Annerly. “Mr. Welter, I am curious to know what associations you have with that photograph and bent wire, the sight of which aroused in you such strong emotion.”

By immense self-control, the president of the American Commodities Company met his eyes fairly. “None,” he answered.

“Impossible! No psychologist, knowing how this record was taken, could look at it without feeling absolutely certain that the photograph and spring caused in you such excessive emotion that I am tempted to give it, without further words, the name of ‘intense fright!’ But if we have inadvertently surprised a secret, we have no desire to pry into it further. Is it not so, Mr. Trant?”

At the name President Welter whirled suddenly. “Trant! Is your name Trant?” he demanded. “Well, I’ve heard of you.” His eyes hardened. “A man like you goes just so far, and then—somebody stops him!”

“As they stopped Landers?” Trant inquired.

“Come, we’ve seen enough, I guess,” said President Welter, and, including for one instant in his now frankly menacing gaze both Trant and Professor Schmalz, turned to the door, closely followed by his companions. And a moment later the quick explosions of his automobile were heard. At the sound, Trant seized suddenly a large envelope, dropped into it the photograph and wire he had just used, sealed, signed, and dated it, signed and dated also the record from the instruments, and hurriedly handed all to Dr. Annerly.

“Doctor, I trust this to you,” he cried, excitedly. “It will be best to have them attested by all three of you. If possible get the record photographed to-night, and distribute the photographs in safe places. Above all, do not let the record itself out of your hands until I come for it. It is important—extremely important! As for me, I have not a moment to lose!”

He seized his hat and dashed from the room, leaving them in an astonished group.

The young psychologist sped down the stone steps of the laboratory three at a time, ran at top speed to the nearest street corner, turned it and leaped into a waiting taxicab. “The American Commodities Company’s dock in Brooklyn,” he shouted, “and never mind the speed limits!”

Rentland and the chauffeur, awaiting him in the machine, galvanized at his coming.
