"Tried to. The recorder blew."

"So did all of them. Creepers! What a nasty thing to have around."

Thompson said: "One of my techs is repairing a recorder now. He thinks he can give the wave analysis."

"How?"

"He finds that certain of the crystalline structures in the wave recorder are de-crystallized."

"Meaning what?" demanded Lane.

"Meaning that certain frequencies hit the nuclear resonance of the crystalline structures. I'll let you know."

"Let us know quick," said Downing. "If we can analyze it, we can either reproduce it or shield against it."

"Cats at seven o'clock, forty degrees!" exploded the observer in Lane's ship.

"Anywhere else?" demanded Lane.
