ey. If you don't you are out of luck. If this
Reames guy can't fix up what you want it'll be just too bad
for you."

There was no salutation nor any signature beyond a scrawled and
sprawling "J."

Tommy Reames' jaw set grimly. He folded the scrap of paper and thrust
it back out of sight again.

"Pretty!" he said harshly. "So a gentleman named 'J' is going to pay
Von Holtz for plans or calculations it is hoped I'll provide! Which
suggests--many things! But at least I'll have Von Holtz's help until
he thinks my plans or calculations are complete. So that's all
right...."

Tommy could not be expected, of course, to guess that the note he had
read was quite astounding proof of the interest taken in non-Euclidean
geometry by a vice king of Chicago, or that the ranking beer baron of
that metropolis was the man who was so absorbed in abstruse theoretic
physics.

Tommy moved toward the great solenoid which lay askew upon its wrecked
support. It had drawn the steel globe toward it, had made that globe
vibrate madly, twice, and then go hazy and vanish. It had jerked the
globe in each of five directions, each at right angles to all the
others, and had released it when started in the fifth dimension. The
huge coil was quite nine feet across and would take the steel globe
easily. It was pivoted in concentric rings which made up a set of
gymbals far more elaborate than were ever used to suspend a mariner's
compass aboard ship.

There were three rings, one inside the other. And two rings will take
care of any motion in three dimensions. These rings were pivoted, too,
so that an unbelievably intricate series of motions could be given to
the solenoid within them all. But the device was broken, now. A pivot
had given away, and shaft and socket alike had vanished. Tommy became
absorbed. Some oddity bothered him....

He pieced the thing together mentally. And he exclaimed suddenly.
There had been four rings of metal! One was gone! He comprehended,
very suddenly. The third mirror in the dimensoscope was the one so
strangely distorted by its position, which was at half of a right
angle to all the dimensions of human experience. It was the third ring
in the solenoid's supports which had vanished. And Tommy, staring at
the gigantic apparatus and summoning all his theoretic knowledge and
all his brain to work, saw the connection between the two things.

"The time dimension and the w
