years. The hospital had become a vast, shining tomb staffed by metal ghouls, and he was buried in it. He was suddenly conscious of five miles of earth pressing down on him. But he was alive! He wanted out!
Ross did not realize that he had been shouting until the robot said, "Dr. Pellew told me that you might behave in a non-logical manner at this time. He said to tell you that the future of the human race might depend on what you do in the next few years, and not to do anything stupid in the first few hours."
"How can I get out?" said Ross savagely.
A human being would have avoided the question or simply refused to reply, but the Ward Sister was a robot and had no choice in the matter. Even so, while it was giving the information requested it managed to insert a truly fantastic number of objections to his going. The elevator shaft was blocked, there was danger of contamination and the robot's basic programming forbade it to allow Ross to endanger himself…
"Do you know what going mad is?" said Ross, in a voice he didn't recognize as his own. "Have you had experience of mental instability in humans?"
"Yes, sir."
"It is against your programming to force me, by your inaction, into that state?"
"Yes, sir."
"Then get me to the surface!"
It took three hours.
The Ward Sister ticked a lot and generally got into the nearest approach that a machine could manage to a tizzy. Clearing the elevator shafts — there were five altogether — required the help of heavy maintenance robots and these had been put into a state of low alert two centuries ago and would respond only to direct orders from a human being. But they weren't nearly so bright as the Sister type and, while a single word was enough to set them in motion, it required a great many words to make them understand what he wanted. And the Ward Sister refused to let him into the cage until a full load of Cleaners had tested it first. These delays, by forcing him to think coherently, had a diluting effect on his original feeling of panic, but even he knew that his actions were not those of a sane man.
During the waiting periods between ascents he read parts of the ledger, and now knew what the Emergency had been. A war. According to Pellew it had lasted five months and had been fought to the bitter end by opposing automatic devices, because after the first week no human being could have survived on the surface…
Ross wanted out. Desperately, he wanted away from the unhuman attentions of robots and the sterile death of the wards. He did not expect to find living people on the surface, but he would settle for living things. Trees, insects, grass, weeds. And a sky with clouds and a sun in it and cold, natural air on his face. He didn't think there would be any survivors, but he never stopped hoping…
Each leg of the journey upward was the same. With the Ward Sister at his heels he would stumble out of the cage, yelling for a robot native to the section. When one appeared, invariably another Sister, he would ask, "How many human beings alive in this section?" When the inevitable reply came back he would pause only briefly, then say, "Where are your maintenance robots?" Within minutes he would be surrounded by a mechanical menagerie of repair and construction robots, all ticking at him or asking for clarification of their instructions in voices that were so human that it made Ross's flesh creep. Eventually they would be made to clear the way up to the next section.
Once he came to a level which he recognized as being the lowest section of the hospital of his pre-Sleep days. In this section the dust of centuries lay like gray snow in the corridors and the robots he summoned became the centers of choking, blinding dust storms.
The first level, which was less than one hundred feet beneath the surface, was a shambles. Lighting, elevators, even the native robots were so much wreckage. Great,
