"Give him the can, then," I said.
Barker was to do nothing more than keep watch in the projectoscope plant, and a few moments later he reported himself well concealed, with a splendid view of the floor.
"I think we can take a chance now," Blash said to me, and at my nod, he opened the lid of his dope can. Of course, the fumes did not affect us, through our helmets. They were absolutely without odor or visibility, and in a few seconds the librarians were unconscious. We stepped into the room.
There ensued considerable cautious observation and experiment on the part of Gaunt, working from the military office, and Blash in the library; while Wilma and I, with drawn swords and sharply attuned microphones, stood guard, and occasionally patrolled nearby corridors.
"I hear something approaching," Wilma said after a bit, with excitement in her voice. "It's a soft, gliding sound."
"That's an elevator somewhere," Barker cut in from the projectoscope floor. "Can you locate it? I can't hear it."
"It's to the east of me," she replied.
"And to my west," said I, faintly catching it. "It's between us, Wilma, and nearer you than me. Be careful. Have you got any information yet, Blash and Gaunt?"
"Getting it now," one of them replied. "Give us two minutes more."
"Keep at it then," I said. "We'll guard."
