"The same," said Tina in her crisp fashion. "Yes—undoubtedly the same. So you see why what you have told us was of such interest. Tugh is a Government leader in our world; and now we find he has lived in your Time, and in the Time of this Mary Atwood."

From his seat at the instrument table, Harl burst out: "So he murdered a girl of 1935, and has abducted another of 1777? You would not have me judge him, Tina—"

"No one," she said, "may judge without full facts. This man here—this Larry of 1935—tells us that only a mechanism is in the larger cage—which is what we thought, Harl. And this mechanism, without a doubt, is the treacherous Migul."


here was, in 2930, a vast world of machinery. The god of the machine had developed them to almost human intricacy. Almost all the work of the world, particularly in America, and most particularly in the mechanical center of New York City, was done by machinery. And the machinery itself was guided, handled, operated—even, in some instances, constructed—by other, more intricate machines. They were fashioned in pseudo-human form—thinking, logically acting, independently acting mechanisms: the Robots. All but human, they were—a new race. Inferior to humans, yet similar.

And in 2930 the machines, slaves of idle human masters, had been developed too highly! They were upon the verge of a revolt!

All this Tina briefly sketched now to Larry. And to Larry it seemed a very distant, very academic danger. Yet so soon all of us were plunged into the midst of it!

The revolt had not yet come, but it was feared. A great Robot named Migul seemed fomenting it. The revolt was smouldering; at any moment it would burst; and then the machines would rise to destroy the humans.

This was the situation when Harl and Tugh completed the Time-traveling vehicles in this world. They had been tested, but never used. Then Tugh had vanished; was gone now; and the larger of the two vehicles was also gone.
