Dr. Annerly, bending over the record sheet, uttered a startled exclamation. Trant, glancing keenly at him, straightened triumphantly. But the young psychologist did not pause. He took quickly from his pocket a photograph, showing merely a heap of empty coffee sacks piled carelessly to a height of some two feet along the inner wall of a shed, and laid it in front of the subject. Welter’s face did not alter; but again the pencils shuddered over the moving paper, and the watchers stared with astonishment. Rapidly removing the photograph, Trant substituted for it the bent wire given him by Miss Rowan. Then for the last time he swung to the instrument, and as his eyes caught the wildly vibrating pencils, they flared with triumph. President Welter rose abruptly, but not too hurriedly. “That’s about enough of this tomfoolery,” he said, with perfect self-possession. His jaw had imperceptibly squared to the watchful determination of the prize fighter driven into his corner. His cheek still held the ruddy glow of health; but the wine flush had disappeared from it, and he was perfectly sober. Trant tore the strip of paper from the instrument, and numbered the last three reactions 1, 2, 3. This is the way the records looked: [Illustration: Record of the reaction when Trant said: “A prisoner in the _Elizabethan Age_!”] [Illustration: Record made when Welter saw the photograph of a heap of coffee sacks.] [Illustration: Record made when the spring was shown to Welter.] “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.
