simply that twice as much was being accomplished twice as fast. From his position at one of the high level entrances to the main AUGL ward Conway could look down on a line of ELNTs-six-legged, crab-like entities from Melf IV-scuttling or being towed across the floor of the great tank. Unlike their amphibious patients, the thickly- furred, air breathing Kelgians attending them had to wear protective envelopes which were sweltering hot inside. The scraps of Translated conversation which drifted up to him, although necessarily emotionless, verged on the incandescent. But the work was being done, and much faster than Conway had ever hoped for.
In the corridor behind him a slow procession of Illensans, some in protective suits and the more seriously ill in pressure tents which enclosed their beds, moved past. They were being attended by Earth-human and Kelgian nurses. The transfer was going smoothly now, but there had been a time only half an hour back when Conway had wondered if it would go at all …
When the large pressure tents came through into the water-filled AUGL section they had risen like giant chlorine bubbles and stuck fast against the ceiling. Towing them along the corridor ceiling had been impossible because outgrowths of plumbing might have ruptured the thin envelopes, and getting five or six nurses to weigh them down was impractical. And when he brought in powered stretcher carriers from the level above-vehicles not designed for but theoretically capable of operating under water-with the idea of both holding his super-buoyant patients down and moving them quickly, a battery casing had split and the carrier became the center of a mass of hissing, bubbling water which had rapidly turned black.
Conway would not be surprised to hear that the patient on that particular carrier had a relapse.
He had solved the problem finally with a magnificent flash of inspiration which, he told himself disgustedly, should have come two seconds after he had seen the problem. He had quickly switched the artificial gravity grids in the corridor to zero attraction and in the weightless condition the pressure tents had lost their buoyancy. It meant that the nurses had to swim instead of walk with their patients, but that was a small thing.
It was during the transfer of these PVSJs that Conway learned the reason for Mannon’s “Harrumph” up in Reception-Murchison was one of the nurses on that duty. She hadn’t recognized him, of course, but he knew there was only one person who could fill a nurse’s lightweight suit the way she did. He didn’t speak to her, however-it didn’t seem to be the proper time or place.
Time passed rapidly without another major crisis developing. At Lock Five the Kelgian hospital ship was ready to go, waiting only for some of the hospital’s senior staff to go aboard and for a Monitor ship to escort them out to a safe jump distance. Remembering some of the beings who were scheduled to leave on that ship, many of them friends of long standing, Conway decided the chance offered by the quiet spell to say a quick good-bye to some of them. He called Mannon to tell him where he was going, then headed for Five.
But by the time he arrived the Kelgian ship had gone. In one of the big direction vision panels he could see it drawing away with a Monitor cruiser in close attendance; and beyond them, hanging like newly-formed constellations in the blackness, lay the Monitor defense fleet. The buildup of units around the hospital was proceeding as planned and had increased visibly since Conway had looked at it yesterday. Reassured, and not a little awed by the sight, he hurried back to the AUGL section.
And arrived to find the corridor almost plugged by an expanding sphere of ice.
The ship from Gregory contained a specially refrigerated compartment for beings of the SNLU classification. These were fragile, crystalline, methane-based life-forms who would be instantly cremated if the temperature rose above minus one-twenty. Sector General was currently treating seven of these ultra-frigid creatures, and all of them had been packed into a ten-foot refrigerated sphere for the transfer. Because of the difficulties expected in handling them they were the last patients for the Gregorian ship.
If there had been a direct opening to space from the cold section they would have been moved to the ship along the outer hull, but as this was not possible they had to be brought through fourteen levels from the methane ward to their loading point at Lock Sixteen. In all the other levels the corridors had been spacious and filled with air or chlorine, so that all that the protective sphere had done was to collect a coating of frost and chill the surrounding atmosphere. But in the AUGL section it was growing ice. Fast.
Conway had known this would happen but had not considered it important because the sphere should not have been in the water-filled corridor long enough to cause a problem. But one of the towing lines had snapped and pulled it against some projecting conduit and within seconds they were welded together with ice. Now the sphere was encased in an icy shell four feet thick and there was barely room to pass above or below it.
“Get cutting torches down here,” Conway bawled up to Mannon, “quick!”
Three Corpsmen arrived just before the corridor was completely blocked. With the cutting flames of their torches set to maximum dispersal they attacked the icy mass, melting it free of the projection and trying to reduce it to a more manageable size. In the confined space of the corridor the heat being applied to the ice-ball sent the water temperature soaring up, and none of their suits had cooling units. Conway began to feel a distinct empathy toward boiled lobsters. And the great, awkward mass of ice was a danger to life and limb-danger from being crushed between it and the corridor wall, and the scalding, nearly opaque water which made it so easy to put an arm or leg between the ice and a cutting flame.
But finally the job was done. The container with its SNLU occupants was maneuvered through the inter-level lock into another air-filled section. Conway rubbed a hand across the outside of his helmet in an unconscious attempt to wipe the sweat from his forehead and wondered what else would go wrong.
The answer, according to Dr. Mannon up in Reception was not a thing.
All three levels of DBLF patients had left with the Kelgian ship, Mannon told him enthusiastically, the only caterpillars remaining in the hospital being a few of the nursing staff. Between them the three Illensan freighters had cleared the PVSJ wards of their chlorine-breathers, except for a few stragglers who would be aboard within a few minutes. Among the water-breathing types the AUGLs and ELNTs were clear, and the SNLUs in their baby iceberg were just going aboard. In all fourteen levels had been cleared and that was not a bad day’s work. Dr. Mannon suggested that Dr. Conway might take this opportunity of applying a pillow to his head and going into a state of voluntary unconsciousness in preparation for an equally busy day tomorrow.
Conway was swimming tiredly toward the inter-level lock, his mind revolving around the infinitely alluring concepts of a large steak and a long sleep, when it happened.
Something which he did not see struck him a savage, disabling blow. It bit simultaneously in the abdomen, chest and legs — the places where his suit was tightest. Agony burst inside him like a red explosion that was just barely contained by his tortured body. He doubled up and began to black out, he wanted to die and he desperately wanted to be sick. But some tiny portion of his brain unaffected by the pain and nausea insisted that he did not allow himself to be sick, that being sick inside his helmet was a very nasty way to die …
Gradually the pain receded and became bearable. Conway still felt as if a Tralthan had kicked him in the groin with all six feet, but other things were beginning to register. Loud, insistent, gurgling noises and the extremely odd sight of a Kelgian drifting in the water without its protective suit. A second look told him that it was wearing a suit, but that it was ruptured and full of water.
Further down in the AUGL tank two more Kelgians floated, their long, soft, furry bodies burst open from head to tail, the ghastly details mercifully obscured by an expanding red fog. And against the opposite wall of the tank there was an area of turbulence around a dark, irregular hole through which the water seemed to be leaving.
Conway swore. He thought he knew what had happened. Whatever had made that ragged-edged hole had, because of the non-compressibility of water, also expended its force on the unfortunate occupants of the AUGL tank. But because the other Kelgian and himself had been up here in the corridor they had escaped the worst effects of it.
Or maybe only one of them had escaped …
It took three minutes for him to drag the Kelgian nurse into the lock ten yards along the corridor. Once inside he set the pumps going to clear the chamber of water, simultaneously cracking an air valve. While the last of the water was draining away he struggled to lay the sodden, inert body on its side against one wall. The being’s silvery pelt was a mass of dirty gray spikes, and he could detect no pulse or respiration. Conway quickly lay down on his side on the floor, moved the third and fourth set of legs apart so that he could put his shoulder into the space between them, then with his own feet braced firmly against the opposite wall he began to push rhythmically. Sitting on top of it and pressing down with the palms was not, Conway knew, an effective method of applying artificial respiration to one of the massive DBLFs. After a few seconds water began trickling out of its mouth.
He broke off suddenly as he heard somebody trying to open the lock from the AUGL corridor side. Conway tried his radio, but one or the other of their sets was not working. Taking off his helmet quickly he put his mouth up
