"No, sir," Dowland said. "I think that I have described exactly what I
did hear and see."
"And you feel the Trelawneys established contact with some previous
Earth period--not necessarily the Pleistocene?"
"Yes, I do."
"And you report having seen a spaceship in that prehistorical
period...."
Dowland shook his head. "No, sir. At the moment I was observing it, I
thought it was that. What I reported was having seen something that
looked like a spaceship."
"What do you think it was?"
"A timeship--if there is such a word."
"There is such a word," Camhorn interrupted lazily. "I'm curious to
hear, lieutenant, what brought you to that conclusion."
"It's a guess, sir. But the thing has to fit together somehow. A
timeship would make it fit."
"In what way?"
"I've been informed," Dowland said, "that the Overgovernment's
scientists have been unable to make a practical use of YM because
something has invariably gone wrong when they did try to use it. I also
heard that there was no way of knowing in advance what would happen
to make an experiment fail. But something always would happen, and
frequently a number of people would get killed."
