"It's akin to the Eleusinian mysteries and the cult of Isis," continued Betty unblushingly. "You have to understand 'Karma' (that's reincarnation) and 'Yoga' (that's flitting about in your astral body while you're asleep), and—and—" But here both memory and invention failed her, so she hurriedly changed her point. "Oh! it would take me years to explain, and you couldn't understand unless you'd been initiated. Let's get to the experiment. Will you all stand in a row?"

"Aren't any of you going to try?" asked Irene Jordan, addressing the members of Vb, who, solemn as judges, stood slightly in the background.

"We can only do it with seven, the mystic number—and there are eight of them, and they can't agree who's to be left out," said Betty hurriedly. "It's always done with six neophytes and one initiated. If you're ready, we'd best begin, and not waste any more time."

She arranged her neophytes in a line, and gave to each a plate, telling her to hold it firmly in the left hand. Then, taking her stand facing them, she raised her own plate to the level of her chest.

"Now you must do exactly as I do!" she commanded. "All fix your eyes on me, and don't take them off me for a single instant. The concentration of the seven visual currents is of vital importance. Put the middle finger of the right hand beneath the plate exactly in the centre, then describe a circle with it on the under side of the plate. Be sure the circle follows the same course as the sun, or we may break the mesmeric current. Watch what I'm doing. Now describe a circle on your face in the same manner, beginning with the left cheek. Copy me carefully. And now we must repeat the cabalistic formulary (the oldest in the world—Solomon got it from El Zenobi, the chief of the Genii): 'Om mani padme hum'. Let us say it slowly all together seven times, performing the orthodox circles at each."

The neophytes played their parts admirably. They never removed their gaze from the face of their instructress; they copied her every movement, and repeated the mystic words to the very best of their ability. "Om mani padme hum" rolled from their lips seven times, and seemed to suggest the dreamy atmosphere of the occult.

"The mesmeric current is forming! I can feel it working!" declared Betty. "It only requires further visualization for the hypnotic state to follow. To complete the magnetic circle, will you all kindly turn and face each other?"

Still holding the plates, the obedient six swung round, stared at one another, then gasped and shrieked. And well they might, for, one and all, their countenances were besmirched with black in a series of concentric rings which caused them to resemble Zulu chiefs or American-Indian warriors on the warpath.

"Oh! oh! oh!" came from the members of Vb, who, having been stationed behind the neophytes, had been in equal ignorance of the trick that was being played on them. Then everybody exploded.

"Oh, you look so funny!"
