"No, that would spoil it all. You must wait and see. Barbara, go to the kitchen door and cajole Cook into lending us seven dinner plates. Say you'll pledge your honour not to break them. And purloin a candle from the lamp cupboard. Be as quick as you can! Time wanes."

Barbara executed her errand with speed and success. She soon returned with the plates and set them down on the table. Betty lighted the candle, laid one plate aside, then held each of the others in turn over the flame till the bottoms inside the rims were well coloured with smoke. The girls watched her curiously.

"Now, I'm ready!" she announced, "but I want a messenger. Elyned, you go and tap at Va door and say we shall be very pleased if they care to come and try a most interesting experiment. Mind you put it politely, and for your life don't snigger."

Now Va had been spending an even duller and more wearisome afternoon than Vb, for they had not had the diversion of toasting biscuits. They were yawning in the last stages of boredom when Elyned arrived and delivered her message. Usually they considered themselves far too select to have much to do with the lower division, but to-day anything to break the monotony was welcome. They accepted the invitation with alacrity, and came trooping in to the rival classroom with pleased anticipation in their faces.

"It's a most curious experiment," began Betty. "I learnt it from a cousin who's been out East. He saw it practised by some Chinese priests at a josshouse. I believe it's one of the first steps of initiation in Esoteric Buddhism. My cousin's not exactly a Theosophist, but he's interested in comparative theologies, and he went about with a lama, and found out ever so many of their secrets. He wrote down the formulary of this for me."

"What's it about?" asked the elder girls, looking considerably impressed.

"It's a species of mesmerism—or animal magnetism, as some people prefer to call it. You make certain passes, and repeat certain words after me, and then you all get into the hypnotic state. Of course it depends how psychic you are, but anybody with even undeveloped mediumistic powers will sometimes give replies to questions they couldn't possibly answer in the normal state."

"I suppose it won't hurt us?" asked Agnes Gillard rather gravely.

"Oh, not at all! It's wonderful sometimes to find how people who've never even suspected they possessed psychic gifts bring out absolutely unaccountable pieces of information. It really would be quite uncanny, except for the latest theory that it's merely utilizing a natural power once cultivated by man, but long forgotten except by a few priests in the Tibetan monasteries. The Theosophical Society, of course, is trying to revive it."

"I'm afraid I don't know anything about Theosophy," murmured Hilda Marriott.
