“You were born with a deep enough stability reserve to keep yourself operating for a few decades without any applied biochemical knowledge; you might live twenty years or ninety. Using the knowledge we have, we can play the game longer; but sooner or later we drop the ball. It's not that we don't know the rules; to go back to the chess analogy, it's just that there are too many pieces on the board to keep track of all at once.”
Stubbs shook his head. “I've never thought of it quite that way. To me, it's always been just a repair job, and I couldn't see why it should be so difficult.”
Mancini grinned. “Maybe your cultural grounding didn't include a poem called the 'The Wonderful One-Hoss Shay.' Well, we'll be a couple of hours getting back to the Guppy. There are a couple of sets of analysis runs sitting with us here. Maybe, if I start trying to turn those into language you can follow, you'll have some idea of why the game is so hard before we get there, Maybe, too” — his face sobered somewhat—“you'll start to see why, even though we always lose in the end, the game is so much fun. It isn't just that our own lives are at stake, you know; men have been playing that kind of game for two million years or so. Come on.”
He turned to the bench top on which the various analyzers had been depositing their results; and since Stubbs had a good grounding in mathematical and chemical fundamentals, their language ceased to resemble Basic English. Neither paid any attention as the main driving turbines of the Shark came up to quarter speed and the vessel began to pick her way out of the patch of ice floes where the zeowhales had been collecting metal.
By the time Winkle had reached open water and Ishihara had given him the clearance for high cruise, the other four had lost all contact with the outside world. Dandridge's chess board was in use again, with Farrell now his opponent. The molecular mechanic and his possible apprentice were deeply buried in a task roughly equivalent to explaining to a forty-piece orchestra how to produce Aida from overture to finale — without the use of written music. Stubbs' basic math was, for this problem, equivalent to having learned just barely his “do, re, mi.”
There was nothing to distract the players of either game. The wind had freshened somewhat, but the swells had increased little if at all. With the Shark riding on her hydrofoils there was only the faintest of tremors as her struts cut the waves. The sun was still high and the sky almost cloudless. Between visual pilotage and sonar, life seemed as uncomplicated as it ever gets for the operator of a high-speed vehicle.
The Guppy was nearly two hundred kilometers to the south, far beyond sonar range. Four of her other boats were out on business, and Winkle occasionally passed a word or two with their commanders; but no one had anything of real importance to say. The desultory conversations were a matter of habit, to make sure that everyone was still on the air. No pilot, whether of aircraft, space vessel, surface ship, or submarine, attaches any weight to the proverb that no news is good news.
Just who was to blame for the interruption of this idyll remains moot. Certainly Mancini had given the captain his preliminary ideas about the pest which had killed their first whale. Just as certainly he had failed to report the confirmation of that opinion after going through the lab results with Stubbs. Winkle himself made no request for such confirmation — there was no particular reason why he should, and if he had it is hard to believe that he would either have realized all the implications or been able to do anything about them. The fact remains that everyone from Winkle at the top of the ladder of command to Stubbs at the bottom was taken completely by surprise when the Shark's starboard after hydrofoil strut snapped cleanly off just below the mean planing water line.
At sixty-five knots, no human reflexes could have coped with the result. The electronic ones of the Shark tried, but the vessel's mechanical I.Q. was not up to the task of allowing for the lost strut. As the gyros sensed the drop in the right rear quadrant of their field of perception, the autopilot issued commands to increase the angle of attack of the control foils on that strut. Naturally there was no response. The dip increased. By the time it got beyond the point where the machine thought it could be handled by a single set of foils, so that orders went out to decrease lift on the port-bow leg, it was much too late. The after portion of the starboard flotation hull smacked a wave top at sixty-five knots and, of course, bounced. The bounce was just in time to reinforce the letdown command to the port-bow control foils. The bow curve of the port hull struck in its turn, with almost undiminished speed and with two principal results.
About a third of the Shark's forward speed vanished in less than the same fraction of a second as she gave up kinetic energy to the water in front, raising a cloud of spray more than a hundred meters and subjecting hull and contents to about four gravities of acceleration in a most unusual direction. The rebound was high enough to cause the starboard “wing” to dip into the waves, and the Shark did a complete double cartwheel. For a moment she seemed to poise motionless with port wing and hull entirely submerged and the opposite wing tip pointing at the sky; then, grudgingly, she settled back to a nearly horizontal position on her flotation hulls and lay rocking on the swell.
Externally she showed little sign of damage. The missing strut was, of course, under water anyway, and her main structure had taken only a few dents. The propellers had been twisted off by gyroscopic action during the cartwheel. Aside from this, the sleek form looked ready for service.
Inside, things were different, Most of the apparatus, and even some of the men, had been more or less firmly fixed in place; but the few exceptions had raised a good deal of mayhem.
Winkle and Ishihara were unconscious, though still buckled in their seats. Both had been snapped forward against their respective panels, and were draped with sundry unappetizing fragments of the dissected zeowhale. Ishihara's head had shattered the screen of his sonar instrument, and no one could have told at first glance how many cuts were supplying the blood on his face.
The chess players had both left impressions on the control panel of the winch and handling system, and now lay crumpled beside it. Neither was bleeding visibly, but Farrell's arms were both twisted at angles impossible to intact bones. Dandridge was moaning and just starting to try to get to his feet; he and Mancini were the only ones conscious.
The mechanic had been seated at one of his benches facing the starboard side of the ship when the impact came. He had not been strapped in his seat, and the four-G jerk had started to hurl him toward the bow. His right leg had stopped him almost as suddenly by getting entangled in the underpinning of the seat The limb was not quite detached from its owner; oddly enough, its skin was intact. This was about the only bit of tissue below the knee for which this statement could he made.
Stubbs had been standing at the mechanic's side. They were to argue later whether it had been good or bad luck that the side in question had been the left. It depended largely on personal viewpoint. There had been nothing for Rick to seize as he was snatched toward the bow or, if there was, he had not been quick enough or strong enough to get it. He never knew just what hit him in flight; the motions of the Shark were so wild that it might have been deck, overhead, or the back of one of the pilot seats. It was evident enough that his path had intersected that of the big flask in which Mancini had first collected the iron-feeding tissue, but whether the flask was still whole at the time remains unclear. It is hard to see how he could have managed to absorb so many of its fragments had it already shattered, but it is equally hard to understand how he could have scattered them so widely over his anatomy if it had been whole.
