“I’d say they were safe,” Penrose answered. “The trouble we’ve had with doors around here shows that the metal hasn’t deteriorated.”
In the end, the Japanese girl led the way, more catlike than ever in her caution. The stairs were quite sound, in spite of their fragile appearance, and they all followed her. The floor above was a duplicate of the room they had entered, and seemed to contain about as many books. Rather than waste time forcing the door here, they returned to the middle basement and came up by the escalator down which they had originally descended.
The upper basement contained kitchens—electric stoves, some with pots and pans still on them—and a big room that must have been, originally, the students’ dining room, though when last used it had been a workshop. As they expected, the library reading room was on the street-level floor, directly above the stacks. It seemed to have been converted into a sort of common living room for the building’s last occupants. An adjoining auditorium had been made into a chemical works; there were vats and distillation apparatus, and a metal fractionating tower that extended through a hole knocked in the ceiling seventy feet above. A good deal of plastic furniture of the sort they had been finding everywhere in the city was stacked about, some of it broken up, apparently for reprocessing. The other rooms on the street floor seemed also to have been devoted to manufacturing and repair work; a considerable industry, along a number of lines, must have been carried on here for a long time after the university had ceased to function as such.
On the second floor, they found a museum; many of the exhibits remained, tantalizingly half-visible in grimed glass cases. There had been administrative offices there, too. The doors of most of them were closed, and they did not waste time trying to force them, but those that were open had been turned into living quarters. They made notes, and rough floor plans, to guide them in future more thorough examination; it was almost noon before they had worked their way back to the seventh floor.
Selim von Ohlmhorst was in a room on the north side of the building, sketching the position of things before examining them and collecting them for removal. He had the floor checkerboarded with a grid of chalked lines, each numbered.
“We have everything on this floor photographed,” he said. “I have three gangs—all the floodlights I have—sketching and making measurements. At the rate we’re going, with time out for lunch, we’ll be finished by the middle of the afternoon.”
“You’ve been working fast. Evidently you aren’t being high-church about a ‘qualified archaeologist’ entering rooms first,” Penrose commented.
“Ach, childishness!” the old man exclaimed impatiently. “These officers of yours aren’t fools. All of them have been to Intelligence School and Criminal Investigation School. Some of the most careful amateur archaeologists I ever knew were retired soldiers or policemen. But there isn’t much work to be done. Most of the rooms are either empty or like this one—a few bits of furniture and broken trash and scraps of paper. Did you find anything down on the lower floors?”
“Well, yes,” Penrose said, a hint of mirth in his voice. “What would you say, Martha?”
She started to tell Selim. The others, unable to restrain their excitement, broke in with interruptions. Von Ohlmhorst was staring in incredulous amazement.
“But this floor was looted almost clean, and the buildings we’ve entered before were all looted from the street level up,” he said, at length.
“The people who looted this one lived here,” Penrose replied. “They had electric power to the last; we found refrigerators full of food, and stoves with the dinner still on them. They must have used the elevators to haul things down from the upper floor. The whole first floor was converted into workshops and laboratories. I think that this place must have been something like a monastery in the Dark Ages in Europe, or what such a monastery would have been like if the Dark Ages had followed the fall of a highly developed scientific civilization. For one thing, we found a lot of machine guns and light auto-cannon on the street level, and all the doors were barricaded. The people here were trying to keep a civilization running after the rest of the planet had gone back to barbarism; I suppose they’d have to fight off raids by the barbarians now and then.”
“You’re not going to insist on making this building into expedition quarters, I hope, colonel?” von Ohlmhorst asked anxiously.
“Oh, no! This place is an archaeological treasure-house. More than that; from what I saw, our technicians can learn a lot, here. But you’d better get this floor cleaned up as soon as you can, though. I’ll have the subsurface part, from the sixth floor down, airsealed. Then we’ll put in oxygen generators and power units, and get a couple of elevators into service. For the floors above, we can use temporary airsealing floor by floor, and portable equipment; when we have things atmosphered and lighted and heated, you and Martha and Tony Lattimer can go to work systematically and in comfort, and I’ll give you all the help I can spare from the other work. This is one of the biggest things we’ve found yet.”
Tony Lattimer and his companions came down to the seventh floor a little later.
“I don’t get this, at all,” he began, as soon as he joined them. “This building wasn’t stripped the way the others were. Always, the procedure seems to have been to strip from the bottom up, but they seem to have stripped the top floors first, here. All but the very top. I found out what that conical thing is, by the way. It’s a wind-rotor, and under it there’s an electric generator. This building generated its own power.”
“What sort of condition are the generators in?” Penrose asked.
“Well, everything’s full of dust that blew in under the rotor, of course, but it looks
