calculations and speculations and the remains of frantic efforts to
work out, somehow, the secret which as one manifestation had placed
one mirror so that it hurt the eyes to look at it, and one other
mirror so that from every angle of a normal existence, one could see
only the edge.

"I have worked, Herr Reames," said Von Holtz drearily. "Gott! How I
have worked! But the Herr Professor kept some things secret, and that
so-essential thing is one of them."

Presently he said tiredly:

"The dimension-traveling globe was built in this laboratory. It rested
here." He pointed. "The Herr Professor was laughing and excited at the
moment of departure. His daughter smiled at me through the window of
the globe. There was an under-carriage with wheels upon it. You cannot
see those wheels through the dimensoscope. They got into the globe and
closed the door. The Herr Professor nodded to me through the glass
window. The dynamo was running at its fullest speed. The laboratory
smelled of hot oil, and of ozone from the sparks. I lifted my hand,
and the Herr Professor nodded again, and I threw the switch. This
switch, Herr Reames! It sparked as I closed it, and the flash partly
blinded me. But I saw the globe rush toward the giant catapult yonder.
It leaped upward into the huge coil, which whirled madly. Dazed, I saw
the globe hanging suspended in mid-air, two feet from the floor. It
shook! Once! Twice! With violence! Suddenly its outline became hazy
and distorted. My eyes ached with looking at it. And then it was
gone!"

Von Holtz's arms waved melodramatically.

"I rushed to the dimensoscope and gazed through it into the fifth
dimension. I saw the globe floating onward through the air, toward
that bank of glossy ferns. I saw it settle and turn over, and then
slowly right itself as it came to rest. The Herr Professor got out of
it. I saw him through the instrument which could look into the
dimension into which he had gone. He waved his hand to me. His
daughter joined him, surveying the strange cosmos in which they were.
The Herr Professor plucked some of the glossy ferns, took photographs,
then got back into the globe.

"I awaited its return to our own world. I saw it rock slightly as he
worked upon the apparatus within. I knew that when it vanished from
the dimensoscope it would have returned to our own universe. But it
remained as before. It did not move. After three hours of angu
