He let his breath escape. "How did you do that?"

"You were seeing with my eyes. Your people have invented machines to

do that--the X-ray machine, the fluoroscope. They are crutches. They

cannot do half so well as the eye alone!"

"But it's impossible!" he burst out.

She shook her head. "No. Consider the facts. Even in the densest solid,

there is more space than matter. Every atom is like a miniature solar

system. There is an infinity of space in that bulkhead but only a drop

of matter no bigger than a grain of sand. Is it not true?"

Joel nodded.

Tamis giggled. "You know that, and yet you let the grain of sand

obstruct your view!"

"But why hide yourselves?" he burst out. "With powers like that...."

"I didn't destroy the wall," she interrupted. "I recognized its

transparent qualities. That is all. We have no weapons, no science that

can destroy. We can only hide!"

"But why hide?" he persisted.

She regarded him sadly. "Your people are a hard grasping

race--ruthless. What has happened to the dominant life forms of Mars

and Venus? They are extinct!

"We don't propose to be driven into extinction. We have hidden

ourselves, waiting for a weapon to free Asgard. And now the Republic

itself has given us one!"

"The Republic has given you a weapon!"

"Yes. The maladjusted. The misfits. They are being organized. They are

our weapon!"

"Very interesting!" drawled a low voice from the doorway to the

fo'cs'le.

Tamis gave a startled gasp. Her face paled. Joel sprang to his feet.

Professor Gustav Liedl stood just inside the doorway. He held a small

poisoned needle automatic trained unwaveringly at Joel's belly.
