old of the statue,
pulled at it.

"It--it won't budge," he exclaimed amazedly.

"Eh? Won't move? It's not heavy, is it?" demanded the Professor.

"No--about thirty pounds, but it wont move!"

Gault took hold of one of the angles of the thing, jerked at it
savagely. He gave it up with an oath, returned to Harper's desk
muttering.

Harper suddenly noticed the top portion of the statue. It didn't
seem to be all there! He was positive there had been another
section on top, shooting off at an angle, representing a problem
in tangential stress. What had happened to that top section?

He would figure that out later, when the occasion was more
propitious. Right now, he realized that only the presence of
Dr. Pillbot prevented Gault from firing him. He cast an apprehensive
glance toward his employer.

With trepidation, he saw Gault reach for something projecting
from behind a bench. Gault pulled it out, held it dangling before
him. A strangled exclamation of wrath came from him. His long
nose pointed accusingly toward Harper, like a finger pointing out
a criminal.

"I was afraid of that!" he grated. "Cutting paper dolls!" Gault
was holding up a large paper cutout of a human figure--a long,
rangy man.

"This is the last straw," Gault went on, his voice rising. "I
have stood enough--"

"It--it wasn't me, sir," Harper cried quickly, with visions of
his job and $50,000 vanishing. "It was your ten year old nephew,
Rudolph, when he was here yesterday. He cut it out, said it
looked like--like his uncle--"

Harper stopped as Gault seemed about to explode. Then the
mathematician subsided, a malicious expression crept over his
face.

"H-m-m," he said. "Might be just what I need to explain things to
Dr. Pillbot."

"I shall take this matter before the Psychiatric Society,"
Pillbot was saying excitedly. "Undoubtedly you have some strange
faculty--an instinctive perception of four dimensional laws ...
what was that, Professor?"

"I said if you will step over to this desk I will explain to you
in elementary terms--very elementary and easy to understand--why
you will never be able to study four dimensional beings--_if_ any
exist!" Gault's voice was tinged with sarcasm.

Pillbot came over, followed by Harper, who was interested in any
explanations about the fourth dimension--even elementary ones....

Gault, with a glint in his eye, pressed the paper figure flatly
on the surface of Harper's desk.

"This paper man, we wil
