The indicator-disc came to a stop, in the First Century. He switched on the magnifier and leaned forward to look; he had emerged into normal time in the year 10 of the Atomic Era, a decade after the first uranium-pile had gone into operation, and seven years after the first atomic bombs had been exploded in warfare. The altimeter showed that he was hovering at eight thousand feet above ground-level.
Slowly, he cut out the antigrav, letting the time machine down easily. He knew that there had been no danger of materializing inside anything; the New Tower had been built to put it above anything that had occupied that space-point at any moment within history, or legend, or even the geological knowledge of man. What lay below, however, was uncertain. It was night—the visiscreen showed only a star-dusted, moonless-sky, and dark shadows below. He snapped another switch; for a few microseconds a beam of intense light was turned on, automatically photographing the landscape under him. A second later, the developed picture was projected upon another screen; it showed only wooded mountains and a barren, brush-grown valley.
The time machine came to rest with a soft jar and a crashing of broken bushes that was audible through the sound pickup. Hradzka pulled the main switch; there was a click as the shielding went out and the door opened. A breath of cool night air drew into the hollow sphere.
Then there was a loud bang inside the mechanism, and a flash of blue-white light which turned to pinkish flame with a nasty crackling. Curls of smoke began to rise from the square black box that housed the “time-shift” mechanism, and from behind the instrument-board. In a moment, everything was glowing-hot: driblets of aluminum and silver were running down from the instruments. Then the whole interior of the time machine was afire; there was barely time for Hradzka to leap through the open door.
The brush outside impeded him, and he used his blaster to clear a path for himself away from the big sphere, which was now glowing faintly on the outside. The heat grew in intensity, and the brush outside was taking fire. It was not until he had gotten two hundred yards from the machine that he stopped, realizing what had happened.
The machine, of course, had been sabotaged. That would have been young Zoldy, whom he had killed, or that old billy-goat, Kradzy Zago; the latter, most likely. He cursed both of them for having marooned him in this savage age, at the very beginning of atomic civilization, with all his printed and recorded knowledge destroyed. Oh, he could still gain mastery over these barbarians; he knew enough to fashion a crude blaster, or a heat-beam gun, or an atomic-electric conversion unit. But without his books and records, he could never build an antigrav unit, and the secret of the “temporal shift” was lost.
For “Time” is not an object, or a medium which can be travelled along. The “Time-Machine” was not a vehicle; it was a mechanical process of displacement within the space-time continuum, and those who constructed it knew that it could not be used with the sort of accuracy that the dials indicated. Hradzka had ordered his scientists to produce a “Time Machine,” and they had combined the possible—displacement within the space-time continuum—with the sort of fiction the dictator demanded, for their own well-being. Even had there been no sabotage, his return to his own “time” was nearly of zero probability.
The fire, spreading from the time machine, was blowing toward him; he observed the wind-direction and hurried around out of the path of the flames. The light enabled him to pick his way through the brush, and, after crossing a small stream, he found a rutted road and followed it up the mountainside until he came to a place where he could rest concealed until morning.

It was broad daylight when he woke, and there was a strange throbbing sound; Hradzka lay motionless under the brush where he had slept, his blaster ready. In a few minutes, a vehicle came into sight, following the road down the mountainside.
It was a large thing, four-wheeled, with a projection in front which probably housed the engine and a cab for the operator. The body of the vehicle was simply an open rectangular box. There were two men in the cab, and about twenty or thirty more crowded into the box body. These were dressed in faded and nondescript garments of blue and gray and brown; all were armed with crude weapons—axes, billhooks, long-handled instruments with serrated edges, and what looked like broad-bladed spears. The vehicle itself, which seemed to be propelled by some sort of chemical-explosion engine, was dingy and mud-splattered; the men in it were ragged and unshaven. Hradzka snorted in contempt; they were probably warriors of the local tribe, going to the fire in the belief that it had been started by raiding enemies. When they found the wreckage of the time machine, they would no doubt believe that it was the chariot of some god and drag it home to be venerated.
A plan of action was taking shape in his mind. First, he must get clothing of the sort worn by these people, and find a safe hiding-place for his own things. Then, pretending to be a deaf-mute, he would go among them to learn something of their customs and pick up the language. When he had done that, he would move on to another tribe or village, able to tell a credible story for himself. For a while, it would be necessary for him to do menial work, but in the
