"'Maybe so. Any other sort of trick stuff you want to hear about, Ben? I got a million of'em."

"How about forerunners, and telepathy?"

"Well, telepathy is positively proved, though still unexplained, by Dr. Rhine's experiments. Of course a lot of people had observed it before then, with such frequency as to make questioning it unreasonable. Mark Twain, for example. He wrote about it fifty years before Rhine, with doc.u.mentation and circ.u.mstantial

"detail. He wasn't a scientist, but he had hard common sense and shouldn't have been ignored. Upton Sinclair, too. Forerunners are a little harder. Every one has heard dozens of stories of hunches that came true, but they are hard to follow up in most cases. You might try J. W. Dunne's Experiment with Time for a scientific record under controlled conditions of forerunners in dreams."

"Where does all this get you, Phil? You aren't just collecting

Believe-it-or-nots?"

"No, but I had to a.s.semble a pile of data—you ought to look over my notebooks—before I could formulate a working hypothesis. I have one now."

"Well?"

"You gave it to me—by operating on Valdez. I had begun to suspect sometime ago that these people with odd and apparently impossible mental and physical abilities were no different from the rest of us in any sense of abnormality, but that they had stumbled on potentialities inherent in all of us. Tell me, when you had Valdez' cranium open did you notice anything abnormal in its appearance?"

"No. Aside from the wound, it presented no special features."

"Very well. Yet when you excised that damaged portion, he no longer possessed his strange clairvoyant power. You took that chunk of his brain out of an uncharted area—no known function. Now it is a primary datum of psychology and physiology that large areas of the brain have no known function. It doesn't seem reasonable that the most highly developed and highly specialized part of the body should have large areas with no function; it is more reasonable to a.s.sume that the functions are unknown. And yet men have had large pieces of their cortices cut out without any apparent loss in their mental powers—as long as the areas controlling the normal functions of the body were left untouched.

"Now in this one case, Valdez, we have established a direct connection between an uncharted area of the brain and an odd talent, to wit, clairvoyance. My working hypothesis comes directly from that: All normal people are potentially able to exercise all (or possibly most) of the odd talents we have referred to—telepathy, clairvoyance, special mathematical ability, special control over the body and its functions, and so forth. The potential ability to do these things is lodged in the una.s.signed areas of the brain."

Coburn pursed his lips. "Mmm—I don't know. If we all have these wonderful abilities, which isn't proved, how is it that we don't seem able to use them?"

"I haven't proved anything—yet. This is a working hypothesis. But let me give you an a.n.a.logy. These abilities aren't like sight, hearing, and touch which we can't avoid using from birth; they are more like the ability to talk, which has its own special centers in the brain from birth, but which has to be trained into being. Do you think a child raised exclusively by deaf-mutes would ever leam to talk? Of course not. To outward appearance he would be a deaf-mute."

"I give up," conceded Cob.u.m. "You set up an hypothesis and made it plausible.

But how are you going to check it? I don't see any place to get hold of it. It's a very pretty speculation, but without a working procedure, it's just fantasy."

Huxley rolled over and stared unhappily up through the branches. "That's the rub. I've lost my best wild talent case. I don't know where to begin."

"But, Phil," protested Joan. "You want normal subjects, and then try to develop special abilities in them. I think it's wonderful. When do we start?"

"When do we start what?"

"On me, of course. Take that ability to do lightning calculations, for example.

If you could develop that in me, you'd be a magician. I got bogged down in first year algebra. I don't know the multiplication tables even now!"

CHAPTER THREE.

"Every Man His Own Genius"

"Shall we get busy?" asked Phil.

"Oh, let's not," Joan objected. "Let's drink our coffee in peace and let dinner settle. We haven't seen Ben for two weeks. I want to hear what he's been doing up in San Francisco."

"Thanks, darling," the doctor answered, "but I'd much rather hear about the Mad

Scientist and his Trilby."

"Trilby, h.e.l.l," Huxley protested, "She's as independent as a hog on ice.

However, we've got something to show you this time, Doc."

"Really? That's good. What?"

"Well, as you know, we didn't make much progress for the first couple of months.

It was all up hill. Joan developed a fair telepathic ability, but it was erratic and unreliable. As for mathematical ability, she had learned her multiplication tables, but as for being a lightning calculator, she was a washout."

Joan jumped up, crossed between the men and the fireplace, and entered her tiny

Pullman kitchen. "I've got to sc.r.a.pe these dishes and put them to soak before the ants get at 'em. Talk loud, so I can hear you.

"What can Joan do now, Phil?"

"I'm not going to tell you. You wait and see. Joan! Where's the card table?"

"Back of the couch. No need to shout. I can hear plainly since I got my Foxy

Grandma Stream-lined Ear Trumpet."

"Okay, wench, I found it. Cards in the usual place?"

"Yes, I'll be with you in a moment." She reappeared whisking off a giddy kitchen ap.r.o.n, and sat down on the couch, hugging her knees. "The Great Gaga, the Ghoul of Hollywood is ready. Sees all, knows all, and tells a darnsight more.

Fortunetelling, teethpulling, and refined entertainment for the entire family."

"Cut out the clowning. We'll start out with a little straight telepathy. Throw every thing else out of gear. Shuffle the cards, Ben."

Coburn did so. "Now what?"

"Deal 'em off, one at a time, letting you and me see 'em, but not Joan. Call 'em off, kid."

Ben dealt them out slowly. Joan commenced to recite in a sing-song voice, "Seven of diamonds; jack of hearts; ace of hearts; three of spades; ten of diamonds; six of clubs; nine of spades; eight of clubs—"

"Ben, that's the first time I've ever seen you look amazed."

"Right through the deck without a mistake. Grandfather Stonebender couldn't have done better."

"That's high praise, chum. Let's try a variation. and sit out this one. Don't let me see them. I don't know how it will work, as we never worked with anyone else. Try it."

A few minutes later Coburn put down the last card. "Perfect! Not a mistake."
