s Mary Atwood and I sat chained to the floor of the Time-cage, with Migul the Robot guarding us, I felt that we could not escape. This mechanical thing which had captured us seemed inexorable, utterly beyond human frailty. I could think of no way of surprising it, or tricking it.

The Robot said. "Soon we will be there in 1777. And then there is that I will be forced to do.

"We are being followed," it added. "Did you know that?"

"No," I said. Followed? What could that mean?

There was a device upon the table. I have already described a similar one, the Time-telespectroscope. At this—I cannot say Time: rather must I invent a term—exact instant of human consciousness. Larry, Tina and Harl were gazing at their telespectroscopes, following us.

The Robot said. "Enemies follow us. But I will escape them. I shall go to the Beginning, and shake them off."

Rational, scheming thought. And I could fancy that upon its frozen corrugated forehead there was a frown of annoyance. Its hand gesture was so human! So expressive!

It said. "I forget. I must make several quick trips from 2930 to 1935. My comrades must be transported. It requires careful calculation, so that very little Time is lost to us."

"Why?" I demanded. "What for?"

It seemed lost in a reverie.
