gyrocar. Voices, crisp and anxious, came out of it. He caressed the set
affectionately.

"Listen to 'em, Sergeant," he said hungrily. "They're worried!"

The voice changed suddenly. There was a sudden musical buzzing in the
set, as of two dozen spitting sparks, in as many tones, all going at
once.

"Letting the guys in the Wabbly hear what they hear," said the 'copter
man grimly. "If God's good to us, now...."

The voices changed again. They stopped.

The Wabbly itself was still, halted in its passage across a clear and
rain-swept field by little sparking sounds which seemed to indicate the
presence of something that had better be bombed for safety's sake.

A thin whining noise came down from aloft. It rose to a piercing shriek,
and there was a gigantic crater a half mile from the Wabbly, from which
smoke rose lazily. The Wabbly remained motionless. Another whining noise
which turned to a shriek.... The explosion was terrific. It was a bit
nearer the Wabbly.

"We'll send 'em some more rockets," said the 'copter man.

They went hissing invisibly through the rain. The Wabbly backed
cautiously away from the spot where they landed, because they were
wholly invisible and they made a sound which those in the Wabbly could
not understand. Always, to a savage, the unexplained is dangerous.
Modern warfare has reached the same high peak of wisdom. The Wabbly drew
off from the sparks because it could not know what made them, and
because it had used its power-beam and the bomber had dropped its bombs
without stopping or destroying them. It was not conceivable to anybody
on either the Wabbly or the bombers aloft that inexplicable things could
be especially contrived to confront the Wabbly, unless they were
contrived to destroy it.

"They don't know what in hell they're up against," said the 'copter man
joyously. "Now lets give 'em fits!"

Rockets went off in swift succession. To the blinded men in the bomber
above the clouds it seemed that unexplained mechanisms were springing
into action by dozens, all about the Wabbly. They were mechanisms. They
were electric mechanisms. They were obviously designed to have some
effect on the Wabbly. And the Wabbly had no defense against the
unguessed-at effects of unknown weapons except....

Bombs began to rain from the sky. The Wabbly crawled toward the last gap
left in the ring of mysteri
