Unchallenged,. the witness, a math technician, explained how a Pederson Calculator can go haywire. He cited cases.

Hatton caught him up on one point. “I protest this proof. Rhodesia, as everyone knows, is the location of a certain important experimental industry. Witness has refrained from stating the nature of the work performed in this particular Rhodesian factory. Is it not a fact that the Henderson United Company deals largely in radioactive ores?”

“\Vitness will answer.”

“I can’t. My records don’t include that information.”

“A significant omission,” Hatton snapped. “Radioactivity damages the intricate mechanism of a Pederson Calculator. There is no radium nor radium by-product in the offices of Dugan Sons.”

Vanning stood up. “May I ask if those offices have been fumigated lately?”

“They have. It is legally required.”

“A type of chlorine gas was used.”

“Yes.”

“I wish to call my next witness.”
