Newton smiled. "We'd like another check-out on the process," he said.
"Well, we can go through the mere motions," said Velikof slowly.
"Oh, no," said Newton. "I've a sample here with me."
"With you?" exploded Mangler. "That's dangerous, you idiot."
"Not at all," smiled Newton taking a small flat case from his pocket. It was heavy; lead. He pried it open on the table with a long screwdriver and lifted a small sample out of the case with the tongs. "Now we can do it again," he said happily.
The counters chattered happily as Newton held the sample in front of the probes.
Velikof looked at his watch. "Would you like to try it?" he asked nervously. "The banks close at noon today, you know."
"You have a half-hour. Then, there's always tomorrow."
Velikof shook his head. "Tomorrow I must be gone," he said; "there are men who would kill me for what I've done."
Newton smiled. "You have a good half-hour. I'd like some instructions. Please?"
