The first green form was familiar to him — Ross had been present when it had been filled in. It was dated 29th September, 2017, and gave his name and the details of the condition which required his going into Deep Sleep. It was signed by Dr. Pellew and his assistant. The next one was similarly signed, was dated 4th June, 2036, and stated that the patient had been revived but kept under complete sedation for three weeks while a new treatment was tested. It was unsuccessful. The third form was dated 1st May, 2093, and was signed by a Dr. Hanson. On this occasion he was revived but unconscious for six weeks while a complex treatment involving micro-injections of his bone marrow was tried, again unsuccessfully. His eyes went back to the date: 1st May, 2093!

The problem of Alice was solved, he thought numbly, by simple mathematics: 2017 from 2093 was seventy-six years, and Alice had been twenty-two. His eyes began to sting and Ross hurriedly changed to a less emotionally loaded train of thought. The notes on his chart showed that medical science had left him far behind; relatively, his training was as outdated as bread poultices and bloodletting. And the growth of his fingernails was explained by the periods during which he had been revived but unconscious. He blinked a couple of times, then turned to the next form.

It was dated 17th May, 2233.

Ross could not believe it at first. He suspected a misprint or a new system of dating, until he began to read the notes of the physician in charge. They ran to around three hundred neat, closely written words which detailed a treatment so complex that Ross could only guess at what it had entailed. As before, he had been revived but kept under sedation. Something had been done to him — whether it was something injected or attached or surgically implanted he couldn’t tell — which had brought about a long-term cure, because the notes ended with a terse “Treatment successful, to be revived permanently in 75 years from this day.”

And it was signed by Dr. Pellew and a Sister. At least, the assistant’s space had been rubber-stamped ward sister 5b, but she had forgotten to add her initials.

Ross shook his head in weary confusion. It couldn’t be Pellew’s signature, not after two hundred and sixteen years. It must be a coincidence, he thought, or maybe a great-grandson. Yet he had heard Pellew’s voice — his taped voice, rather — during his awakening. Would a tape recording keep for two hundred years? Ross wasn’t sure, but it might. But then there was that signature…

The next green form, dated 17th May, 2308, was stamped revivication halted: reprocessed at the bottom by the Ward Sister of 5B, who was apparently either too busy or too well known to have to add her initials. There was no doctor’s signature. The next sheet was practically a carbon copy, except for the date, which was four months later, and the last one bore the date 7th October, 2308, and was stamped patient awakened.

Now I know the date, Ross thought, a little wildly; if I had the right time I could set my watch!

All at once Ross felt so unutterably weary that he wanted to lie on the floor and sleep. For a patient just out of Deep Sleep he had been behaving stupidly indeed. Instead of a few minutes’ gentle exercise, he had been stumbling about the corridor and sitting on an uncomfortable chair, of the kind designed to keep Night Sisters awake, for the best part of an hour. It was high time he got into bed. Perhaps his brain would be able to make something out of the confused mass of data, after he got some sleep.

Five minutes later Ross was between the sheets, which turned out to be of fine, woven plastic. Their only sign of age was a tendency toward yellow in places. He tried to sleep but his curiosity kept him awake. The green folder, which he had brought along and hidden under his pillow, lay a few inches from his hand. In those unread pages he might find the answer to everything or he might be thrown into worse confusion. He was sure that the contents of the folder would do nothing to increase his peace of mind. But Ross was beginning to be afraid again and he wanted to do everything possible to find out exactly what he feared.

Groaning, he levered himself to one elbow, drew out the folder and began to read.

Immediately following the 508s which he had already studied there was a two-page instructional circular dealing with the transfer of staff to the extension of the five-mile level. This would be devoted to the study of non-sterile mutations. Two Doctors and four Sisters were listed by name and there was a note stating that owing to the shortage of staff the cleaners would also serve as nursing orderlies and be allowed to administer simple courses of treatment without supervision. Dated March, 2062, the circular was signed by Dr. Pellew.

The next five sheets dealt primarily with the reorganization due to the shortage of staff and covered a period of about twenty years. Apparently some of the wards were then operating with just a Sister and two Cleaners. In addition to the cleaning and maintenance work, these people, who had once been considered the lowliest members of the staff, were being given increasingly responsible duties with regard to the patients. They had become Cleaners with a capital C, like Doctors and Sisters.

Ross’s mind was bursting with questions. He turned quickly to the next page, hoping that the answers to some of them might be there.

Two short paragraphs, in bold type and underlined, practically shouted up at him.

During the Emergency all sections shall be rendered self-contained and self-sufficient. Transfer of staff, food, medical supplies and servomechanisms is forbidden. Penalty for contravening this regulation, regardless of circumstances, is exclusion from the home section. Con-tact between sections shall be by intercommunication phone only.

All Deep Sleep patients with a favorable prognosis shall be transferred immediately to the Non-sterile Mutations section. Patients to be transferred are…

A list of case numbers followed, Ross’s being one of them.

So there had been an Emergency. Ross didn’t like the sound of that at all. His hand was shaking with more than fatigue when he turned that page over.

There followed four closely typed pages which were the minutes of a meeting held by all the medical staff of the section, dated 6th July, 2071, Dr. Hanson presiding. Under discussion were the new techniques for treating patients while actually in the Deep Sleep state. The only drawback was that the new treatment required many decades to effect a cure, and, with the exception of Dr. Hanson, who had been born in the section, all the Doctors were men in their sixties. They were therefore faced with the problem of reviving nearly thirty Deep Sleep patients in fifty-odd years later, at which time they themselves would have long since been dead.

The only possible answer was for the Doctors to go into suspended animation also until the time when their patients were due to be revived. However, at least one Doctor would have to remain awake to supervise and to continue with some of the more promising lines of research, which, if they were lucky, might result in cures for all of their suspended patients. A timetable of twenty years asleep and two awake was suggested, with a three-month overlap to allow the newly awakened Doctor to take over the reins. Being the youngest of the group, Dr. Hanson asked that his waking term be extended to five years, as he was working on a line which might produce a cure for the heart condition which had forced their previous director to undergo suspended animation. They must agree that if Dr. Pellew could be cured and revived, his help would be invaluable. Mention was made of the psychological dangers present in the scheme, and methods suggested for guarding against them, and the report ended with discussion of the staff problem. It was decided to give Cleaners more responsibility and allow the Ward Sisters the right to diagnose, treat and perform limited surgery.
