798 sheet above the other two and wired electrically to a key like that of a telegraph instrument fastened to the table. When this key is in its normal position this pencil makes simply a straight line upon the sheet; but instantly when the key is pressed down, the line breaks downward also.

This third instrument is used merely to record on the sheet, by the change in the line, the point at which the object that arouses sensation or emotion is displayed to the person undergoing examination.

The instant's silence which followed Schmalz's rapid explanation was broken by one of Welter's companions with the query:

"Well, what's the use of all this stuff, any way?"

"Ach!" said Schmalz, bluntly, "it is interesting, curious! I will show you."

"Will one of you gentlemen," said Trant, quickly, "permit us to make use of him in the demonstration?"

"Try it, Jim," Welter laughed, noisily.

"Not I," said the other. "This is your circus."

"Yes, indeed it's mine. And I'm not afraid of it. Schmalz, do your worst!" He dropped, laughing, into the chair the professor set for him, and at Schmalz's direction unbuttoned his vest. The professor hung the pneumograph around his neck and fastened it tightly about the big chest. He laid Welter's forearm in a rest suspended from the ceiling, and attached the cylinder to the second finger of the plump hand. In the meantime Trant had quickly set the pencils to bear upon the record sheet and had started the cylinder on which the sheet traveled under them.

"You see, I have prepared for you." Schmalz lifted a napkin from a tray holding several little dishes. He took from one of these a bit of caviar and laid it upon Welter's tongue. At the same instant Trant pushed down the key. The pencils showed a slight commotion, and the spectators stared at this record sheet!

"Ach!" exclaimed Schmalz, "you do not like caviar."

"How do you know that?" demanded Welter.

"The instruments show that at the unpleasant taste you breathe less freely—not so deep. Your finger, as under strong sensation or emotions, grows smaller, and your pulse beats more rapidly."

"By the Lord! Welter, what do you think of that?" cried one of his companions; "Your finger gets smaller when you taste caviar!"

It was a joke to them. Boisterously laughing, they tried Welter with other food upon the tray; they lighted for him one of the black cigars of which he was most fond, and watched the trembling pencils write the record of his pleasure at the taste and smell. Through it all Trant waited, alert, watchful, biding the time to carry out his plan. It came when, having exhausted the articles at hand, they paused to find some other means to carry on the amusement. The young psychologist leaned forward suddenly.

"It is no great ordeal after all, is it, Mr. Welter?" he said. "Modern psychology does not put its subjects to torture like"—he halted, meaningly—"a prisoner in the Elizabethan Age!"

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:

"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
