The memories were coming back. This time, he didn't try to probe for them; he just let them flow.
He turned around again and looked deliberately at the big, bulky table. There was a faint humming noise coming from it which had escaped his notice before. He walked over to it and looked at the queerly-shaped things that lay on its shining surface. He had already decided that the table was no more wood than the wall, and a touch of a finger to the surface verified the decision.
The only thing that looked at all familiar on the table was a sheaf of written material. He picked it up and glanced over the pages, noticing the neat characters, so unlike any that he knew. He couldn't read a word of it. He grinned and put the sheets back down on the smooth table top.
The humming appeared to be coming from a metal box on the other side of the table. He circled around and took a look at the thing. It had levers and knobs and other projections, but their functions were not immediately discernible. There were several rows of studs with various unrecognizable symbols on them.
This would certainly be something to tell in London—when and if he ever got back.
He reached out a tentative finger and touched one of the symbol-marked studs.
There was a loud click! in the stillness of the room, and he leaped back from the device. He watched it warily for a moment, but nothing more seemed to be forthcoming. Still, he decided it might be best to let things alone. There was no point in messing with things that undoubtedly controlled forces beyond his ability to cope with, or understand. After all, such a long time—
He stopped, Time? Time?
What had Contarini said about time? Something about its being like a river that flowed rapidly—that much he remembered. Oh, yes—and that it was almost impossible to try to swim backwards against the current or ... something else. What?
He shook his head. The more he tried to remember what his fellow prisoner had told him, the more elusive it became.
