And he found what he was looking for. In both worlds, men were working on research problems. It was a crazy scene; the laboratories were in excellent register, and appeared as one. The men, of course, were free to move, and they were not performing the same acts. It made for a blurring, maddening scene to watch men working furiously in a large laboratory and working through one another.

Their fellows stopped work also, and each group went below.

"This," said Tansie Lee, "is where we part."
"Part?" he asked in wonder.

"When do we part?"
"As soon as you are successful."
"I'll be looking for you," he said. Then he stopped short, standing in the hallway of the laboratory as the men trouped past—through—the two of them on their way to the cyclotron chamber below.
