“A human mind possesses free will, initiative,” Sister protested. “No robot could—”

“Exercise initiative. But you did it when you awakened me without a brace of Cleaners sitting on my chest And since then there have been improvements. The robots have given way to steamships.” He laughed awkwardly and added, “That was a pun.”

Sister said, “From my reading I know that steam-driven vessels were a later development than those propelled by oars, just as you have caused us to develop since your awakening. But I cannot understand why you used the word ‘robots’ when you should have said ‘row-boats,’ unless the accidental similarity of sounds…”

That particular discussion lasted for nearly three hours and broke off only because it was time for the lights to go out. To Sister the division between waking and sleeping periods was sharp. In the middle of a sentence she stopped speaking, paused, then finished, “It is time to go to sleep, Mr. Ross. Is there anything you want before I go into low alert?”

It was always the same formula and Ross had become tired of hearing it. Bitterly he said, “Yes, there is. I want a human female aged twenty, weighing one hundred and fifteen pounds, dark brown hair, brown eyes…” Under his breath he added, “…called Alice.”

“Your request has been noted, but at the present time we are unable to—” began the robot.

“Good night, Sister,” Ross said, and rolled onto his side.

He wanted to dream about Alice that night, but instead he dreamed that he was in a small, sealed room deep underground where the air was rapidly going stale. If he wanted to go on living it was imperative that he do something, quickly…

When Sister finally released him by speaking the magic word “sir” the First Expedition, as Ross liked to think of it, was ready to go. The same sense of frantic urgency which claimed his waking and sleeping moments alike tempted him to send it out quickly and with no change in the instructions he had already given. But although Sister had forbidden him to do everything else, she had not stopped him from thinking, or rather revising his thinking with regard to the purpose of the expedition. He had to consider the possibility that there might not be any other human beings left alive in the world he was proposing to search. If that should be the case Ross would have to take a long-term view.

A very long-term view…

The world he knew was either incinerated or almost aseptically clean. On the surface the war had been responsible for the former, and underground the conditions had been due to overzealous cleaning robots. With the exception of Ross himself, there was no organic life inside the hospital, not even on the microscopic level. There were no lab animals, living or dead. Like the corpses of the humans who had died, they had been cremated a few hours after death, and his own body wastes were similarly treated. The food containers, which still exploded in his face with irritating frequency, held a synthetic which never had been alive.

Ross had had the idea of finding some warm, tidal pool and filling it with all the scraps and leavings of organic life that he could find in the hope that sometime something in that hodgepodge of warring microorganisms would develop and grow until the evolutionary processes could take over again. He had been thinking in terms of millions of years, naturally, taking the long view.

But the tidal pools were choked with ash and soot, and even if his idea was possible a sudden storm or unusually high tide could wash his experiment back into the sea, where the material would become so diluted that no reaction could take place. And the idea was no good anyway because the robots had done a too thorough job of cleaning up.

That was why the First Expedition did not start out until two weeks later — it required that time to reprogram the Miner to search for and protect Life and not just human life. The books on plant ecology and horticulture were severely limited in the hospital, but his instructions included the necessity for absorbing any other data on this and related subjects which the expedition might uncover during their search, Small animals if any, insects, plants, weeds or fungus growths — all were to be reported, their positions marked and steps taken for their preservation until they could be moved to the hospital with absolute safety, for them. And finally Ross had given instructions regarding every contingency he could think of and he gave the order to move out.

On four sets of massive caterpillar treads the Miner %

rumbled through the thirty-foot gap which had been cut in the dome. Ross had been forced to compromise with his original idea for an all-purpose, unspecialized machine, but as he watched his monstrous brainchild go churning past he thought that he had made a good compromise. The powered tread sections were simply a vehicle to transport the digger-nurse unit — which was the seat of the robot’s not inconsiderable brain — and to house the information-gathering and retransmitting devices. It literally bristled with antennae, both fixed and rotating, spotlights, camera supports and deep-level metal-detection equipment which gave its outline an indistinct, sketched-in look. Sitting atop this transporter section with its conical drill reflecting red highlights, the digger-nurse unit pointed aggressively forward. In operation the digger would lift itself clear of the transporter, stick its blunt nose into the ground and go straight down. Like a hot marble sinking through butter, Ross had thought when he watched the first test run. Outwardly it was a monstrous, terrifying object, which was why Ross had ordered it and the four robots following it to be painted with a large red cross. He didn’t want anyone to get the wrong idea about them.

Watching the cavalcade go past — Big Brother trailed by two repair robots and two Sisters modified for long-distance surface travel — Ross thought that a little stirring music would not have been amiss. He strained his eyes to keep them in sight as they rolled and lurched down the hillside, but it had been two days since the last rain and the ash was beginning to blow about again. Ross stopped himself from waving good-bye at them with a distinct effort; then he turned and began walking toward the small control dome.

Here had been installed the equipment which enabled him to see all that the search robots saw, and here it was that Ross spent every waking moment of the next five days. He watched the Miner’s radar repeater screens, its forward TV and the less detailed but more penetrating infrared vision. Every half-hour or less he checked that it was still on course, which it always was, and many times he asked if it had found anything even though the repeaters told him that it hadn’t. By turns he was bored and frantically impatient, and bad-tempered all the time.

Some of the things he said and did were petty. He knew it and was ashamed of himself, but that didn’t stop him from saying them. But one of the incidents, on the other hand, gave him just cause for losing his temper. The matter of the exploding food containers.

“I am getting fed up with being plastered with this muck every, other mealtime!” he had raged, while trying to get rid of the foul-smelling goo, which, because of some trace impurities present during its manufacture, had in two hundred years turned into a particularly noisome stink bomb. “Go through the stores and separate the unspoiled from the rotten, then bring me only the edible stuff from now on. You shouldn’t have to be told such a simple thing!”

“Doing what you suggest would mean opening every single can, sir,” Sister had replied quietly. “That would cause all the food to spoil within a short time. It is therefore impossible—”
