  A development of the artificial gravity system which compensated for the killing accelerations used by Federation spaceships, and the repulsion screen which gave protection against meteorites or which allowed a vessel with sufficient power reserves to hover above a planetary surface like an old-time dirigible airship, the rattler beam simply pushed and pulled, violently, with a force of up to one hundred Gs, several times a minute.

  It was very rarely that the Corps were forced to use their rattlers in anger—normally the fire control officers had to be satisfied with using them to clear and cultivate rough ground for newly-established colonies—and for the optimum effect the focus had to be really tight. But even a diffuse beam could be devastating, especially on a small target like a scoutship. Instead of tearing off large sections of hull plating and making metallic mincemeat of the underlying structure, it shook the whole ship until the men inside rattled.

  On this operation, however, the focus was very tight and the range known to the last inch.

  Visually it was not at all spectacular. Each cruiser had three rattler batteries which could be brought to bear, but they pushed and pulled so rapidly that the surface seemed hardly to be disturbed. Only the relatively gentle tractor beams positioned between the rattlers seemed to be doing anything—they pulled up the narrow wedge of material and shredded vegetation so that the next rattler in line could deepen the incision. It would not be until the incision had penetrated to the subsurface and extended for several miles that the other squadrons still hanging in orbit would come in to widen the cut into what they all hoped would be a trench wide enough to check the spread of vegetable infection from the excised and decomposing dead material.

  As a background to the pictures Conway could hear the clipped voices of the ordnance officers reporting in. There seemed to be hundreds of them, all saying the same things in the fewest possible words. At irregular intervals a quiet, unhurried voice would break in, directing, approving, coordinating the overall effort—the voice of God, sometimes known as Fleet Commander Dermod, the ranking Monitor Corps officer of Galactic Sector Twelve and as such the tactical director of more than three thousand major fleet units, supply and communications vessels, support bases, ship production lines, and the vast number of beings. Earth-human and otherwise, who manned them.

  If the operation came unstuck, Conway certainly would not be able to complain about the quality of the help. He began to feel quietly pleased with the way things were going.

  The feeling lasted for all of ten minutes, during which time the incision line passed through the tunnel—Number Forty-three—which they had just entered. Conway could actually see the inward end of the seal, a thick, corrugated sausage of tough plastic inflated to fifty pounds per square inch which pressed against the tunnel walls. Special arrangements had been needed to guard against loss of working fluid because the strata creature’s healing processes were woefully slow. Its blood was quite literally water and one important quality which water did not have was the ability to coagulate.

  Two Corpsmen and a Melfan medic were on guard beside the seal. They seemed to be agitated, but there were so many leucocytes moving about the tunnel that he could not see the reason for it. His screens showed the incision line crossing the throat tunnel. A few hundred gallons of water between the seal and the incision poured away—considering the size of the patient, it was scarcely a drop. The rattlers and tractors moved on, extending and deepening the cut while the great immaterial pressor beams, the invisible stilts which supported the enormous weight of the cruisers, pushed the edges apart until the incision became a widening and deepening ravine. A small charge of chemical explosive brought down the roof of the emptied section of tunnel, reinforcing the plastic seal. Everything seemed to be working exactly as planned, until the immediate attention signal began flashing on his board and Major Edwards’ face filled the screen.

  ‘Conway,’ said the Major urgently, ‘the seal in Tunnel Forty-three is under attack by tools.’

  ‘But that’s impossible,’ said Murchison, in the scandalised tones of one who has caught a friend cheating at cards. ‘The patient has never interfered with our internal operations. There are no eye plants down here to give away our positions, no light to speak of, and the seal isn’t even metal. They never attack plastic material on the surface, just men and machines.’

  ‘And they attack men because we betray our presence by trying to take mental control of them,’ Conway said quickly, then to Edwards, ‘Major, get those people away from the seal and into the supply shaft. Quickly. I can’t talk to them directly. While they’re doing that tell them to try not to think-’

  He broke off as the seal ahead disappeared in a soft white explosion of bubbles which roared towards them along the tunnel roof. He could not see anything outside the digger and inside only Edwards’ face and pictures of ships in line astern formation.

  ‘Doctor, the seal’s gone,’ shouted the Major, his eyes sliding to one side. ‘The debris behind the seal is being washed away. Harrison, dig in!’

  But the Lieutenant could not dig in because the bubbles roaring past made it impossible to see. He threw the tracks into reverse, but the current sweeping them along was so strong that the digger was just barely in contact with the floor. He killed the floodlights because reflection from the froth outside the canopy was dazzling them. But there was still a patch of light ahead, growing steadily larger...

  ‘Edwards, cut the rattlers... !’

  A few seconds later they were swept out of the tunnel as part of a cataract which tumbled down an organic cliff into a ravine which seemed to have no bottom. The vehicle did not explode into its component parts nor themselves into strawberry jam, so they knew that Major Edwards had been able to kill the rattler batteries in time. When they crashed to a halt a subjective eternity later, two of the repeater screens died in spectacular implosions and the cataract which had cushioned their fall on the way down began battering at their side, pushing and rolling them along the floor of the incision.

  ‘Anyone hurt?’ said Conway.

  Murchison eased her safety webbing and winced. ‘I’m black and blue and ... and embossed all over.’

  ‘That,’ said Harrison in an obviously uninjured tone, ‘I would like to see.’

  Both relieved and irritated, Conway said, ‘First we should see to our patient.’

  The only operable viewscreen was transmitting a picture taken from one of the copters stationed above the incision. The heavy cruisers had drawn off a short distance to leave the operative field clear for rescue and observation copters, which buzzed and dipped above the wound like great metal flies. Thousands of gallons of water were pouring from the severed throat tunnel every minute, carrying the bodies of leucocytes, farmer fish, incompletely digested food and clumps of vital internal vegetation into and along the ravine. Conway signalled for Edwards.

  ‘We’re safe,’ he said before the other could speak, ‘but this is a mess. Unless we can stop this loss of fluid, the stomach system will collapse and we will have killed instead of cured our patient. Dammit, why doesn’t it have some method of protecting itself against gross physical injury, a non-return valve arrangement or some such? I certainly did not expect this to happen....’

  Conway checked himself, realising that he was beginning to whine and make excuses instead of issuing instructions. Briskly, he said, ‘I need expert advice. Have you a specialist in short-range, low-power explosive weapons?’

  ‘Right,’ said Edwards. A few seconds later a new voice said, ‘Ordnance control, Vespasian, Major Holroyd. Can I help you, Doctor?’

  I sincerely hope so, thought Conway, while aloud he went on to outline his problem.

  They were faced with the emergency situation of a patient bleeding to death on the table. Whether the being concerned was large or small, whether its body fluid was Earth-human blood, the superheated liquid metal used by the TLTUs of Threcald Five, or the somewhat impure water which carried food and specialised internal organ
isms to the farflung extremities of this Drambon strata creature’s body, the result would be the same—steadily reducing blood pressure, increasingly deep shock, spreading muscular paralysis, and death.

  Normal procedure in these circumstances would be to control the bleeding by tying off the damaged blood vessel and suturing the wound. But this particular vessel was a tunnel with walls no more strong or elastic than the surrounding body material, so they could not be tied or even clamped. As Conway saw it the only method remaining was to plug the ruptured vessel by bringing down the tunnel roof.

  ‘Close-range TR-7S,’ said the ordnance officer quickly. ‘They are aerodynamically clean, so there will be no problem shooting into the flow, and provided there are no sharp bends near the mouth of the tunnel any desired penetration can be achieved by-’

  ‘No,’ said Conway firmly. ‘I’m concerned about the compression effects of a large explosion in the tunnel itself. The shock wave would be transmitted deep into the interior and a great many farmer fish and leucocytes would die, not to mention large quantities of the fragile internal vegetation. We must seal the tunnel as close to the incision as possible, Major, and confine the damage to that area.’

  ‘Armour-piercing B-22s, then,’ said Holroyd promptly. ‘In this material we could get penetrations of fifty yards without any trouble. I suggest a simultaneous launch of three missiles, spaced vertically above the tunnel mouth so that they will bring down enough loose material to block the tunnel even against the pressure of water trying to push it away as it subsides.’

  ‘Now,’ said Conway, ‘you’re talking.’

  But Vespasian’s ordnance officer could do more than talk. Within a very few minutes the screen showed the cruiser hovering low over the incision. Conway did not see the missiles launched because he had suddenly remembered to check if their digger had been swept far enough to avoid being buried in the debris, which fortunately it had. His first indication that anything at all had happened was when the flow of water turned suddenly muddy, slowed to a trickle and stopped. A few minutes later great gobs of thick, viscous mud began to ooze over the lip of the tunnel and suddenly a wide area around the mouth began to sag, fall apart, and slip like a mass of brown porridge into the ravine.

  The tunnel mouth was now six times larger than it had been and the patient continued to bleed with undiminished force.

  ‘Sorry, Doctor,’ said Holroyd. ‘Shall I repeat the dose and try for greater penetration ?’

  ‘No, wait.’

  Conway tried desperately to think. He knew that he was conducting a surgical operation, but he did not really believe it—both the problem and the patient were too big. If Murchison or Harrison were in the same condition, even if no instruments or medication were available, he would know what to do—check the flow at a pressure point, apply a tourniquet... that was it!

  ‘Holroyd, plant three more in the same position and depth as last time,’ he said quickly. ‘But before you launch them can you arrange your vessel’s pressor beams so that as many of them as possible will be focused just above the tunnel opening ? Angle them against the face of the incision instead of having them acting vertically, if possible. The idea is to use the weight of your ship to compress and support the material brought down by the missiles.’

  ‘Can do, Doctor.’

  It took less than fifteen minutes for Vespasian to rearrange and refocus her invisible feet and launch the missiles, but almost at once the cataract ceased and this time it did not resume. The tunnel opening was gone and in its place there was a great, saucer-shaped depression in the wall of the incision where Vespasian’s starboard pressors were focused. Water still oozed through the compacted seal, but it would hold so long as the cruiser maintained position and leaned her not inconsiderable weight on it. As extra insurance another inflatable seal was already being moved into the supply tunnel.

  Suddenly the picture was replaced by that of a lined, young old face above green-clad shoulders on which there rested a quietly impressive weight of insignia. It was the Fleet Commander himself.

  ‘Doctor Conway. My flagship has engaged in some odd exercises in her time, but never before have we been asked to hold a tourniquet.’

  ‘I’m sorry, sir—it seemed the only way of handling the situation. But right now, if you don’t mind, I’d like you to have this digger lifted to map reference numbers....’

  He broke off because Harrison was waving at him. The Lieutenant said softly, ‘Not this digger. Ask him to have the other one checked out and waiting when they get around to pulling us out.’

  Six

  Three hours later they were in the second modified and strengthened digger, suspended under a transport copter and approaching the area which, they hoped, contained the strata creature’s brain and/or tool-producing facilities. The trip gave them a chance to do some constructive theorising about their patient.

  They were now convinced that it had evolved originally from a mobile vegetable form. It had always been large and omnivorous and when this life-form began to live off itself the parts grew in size and complexity and shrank in numbers. There did not seem to be any way that the strata creature could reproduce itself, it simply continued to live and grow until one of its own kind who was bigger than it was killed it. Their patient was the biggest, oldest, toughest, and wisest of its kind. As the sole occupant of its land mass for many thousands of years, there had no longer been the necessity for it to move itself bodily and so it had taken root again.

  But this had not been a process of devolution. With no chance of cannibalising others of its own kind, it devised methods of controlling its growth and of rendering its metabolism more efficient by evolving tools to do the jobs like mining, investigating the subsurface, processing necessary minerals for its nerve network. The original farmer fish were probably a strain which were able to survive, like the legendary Jonah, in its stomach and later grow plant teeth for both the parent creature and the farmer fish to defend themselves against sea predators sucked in by the mouths. How the leucocytes got there was still not clear, but the rollers occasionally ran across a smaller, less highly evolved variety which were probably the leeches’ wild cousins.

  ‘But one point which we must keep in mind when we try to talk to it,’ Conway ended seriously, ‘is that the patient is not only blind, deaf, and dumb, it has never had another of its own kind to talk to. Our problem isn’t simply learning a peculiar and difficult e-t language, we have to communicate with something which does not even know the meaning of the word communicate.’

  ‘If you’re trying to raise my morale,’ said Murchison drily, ‘you aren’t.’

  Conway had been staring ahead through the forward canopy, mostly to avoid having to look at the carnage depicted on his repeater screens where the tool attacks were taking an increasingly heavy toll at the feeding and transfusion sites. He said suddenly, ‘The suspected brain area is far too extensive to be searched quickly but, correct me if I’m wrong, isn’t this also the locality where Descartes made her first touchdown? If that is so then the tools sent to investigate her had a relatively short distance to come, and if it is possible to trace the path of a tool by the scar tissue it leaves in the body material...’

  ‘It is,’ said Murchison, looking excited. Harrison gave new instructions to the transport copter’s pilot without having to be told, and a few minutes later they were down, cutting blades spinning and nosing into their patient’s spongy quasi-flesh.

  But instead of the large, cylindrical plug cut from the body material they found a flat, reversed conical section which tapered sharply to a narrow, almost hair-thin wound which angled almost at once towards the suspected brain area.

  ‘The ship would have been drawn only a short distance below the surface, obviously,’ said Murchison. ‘Enough to let tools make contact with its total surface while supported by body material, instead of making a fleeting contact after bouncing themselves into the air. But do you notice how the tools, even t
hough they must have been cutting through at top speed, still managed to avoid severing the root network which relays their mental instructions?’

  ‘At the present angle of descent,’ Harrison cut in, ‘we are about twenty minutes from the subsurface. Sonar readings indicate the presence of caverns or deep pits.’

  Before Conway could reply to either of them, Edwards’ face flicked on to the main screen. ‘Doctor, seals Thirty-eight through Forty-one have gone. We’re already holding tourniquets at Eighteen, Twenty-six, and Forty-three, but-’
