Late afternoon found him flying above the Caribbean. When he saw the island. It was one of many, a small, flat mound of green ringed by a white halo of surf, and Ross did not know why he picked it in particular. Perhaps it was the tiny bay. which gleamed like a yellow horseshoe on its western shore which caused him to order the aircraft to land. Certainly he had been feeling like a swim for the past few hours.
Sister raised no objections beyond reminding him that he was not to overexert himself, that in the time since his last exposure to sunlight the mechanics of stellar evolution had brought about a significant increase in solar radiation, and that in all the world there remained not one usable tube of sunburn lotion. Nodding soberly, Ross told her that he would bear all these points in mind. Then he wheeled and went charging down the beach and, with a wild yell, dived into a monster wave which was just beginning to curl at the top.
After the swim he moved inland to where the sand gave way to long, hot grass, and lay down to dry off. The sun was very hot, despite its being only an hour before sunset. A great, drowsy happiness filled Ross, and a quiet optimism for the future of his world, his robots and his race. He was too sleepy and contented at the moment to work out details, but, considering what he had already accomplished, he felt very confident. Sighing, he rolled onto his back, and his fingers unconsciously went through the motions of pulling a long stem of grass and placing it between his teeth. He began to chew.
At that point Sister informed him that the grass he was chewing was not one of the edible strains, but that its use in small quantities would not prove harmful. Ross laughed, then climbed to his feet and headed toward the aircraft. There he made a sizable dent in its food store and a somewhat larger one in its bunk. And so ended the happiest day of his life.
Ross awoke next morning to find the ship airborne and climbing to avoid a hurricane which was sweeping in from the southwest. An hour later, two hundred miles west of Panama, he spotted the vapor trail of another A17 and spoke with it briefly without diverting it from its search duties. He had barely finished speaking when he saw a long, whitish smudge on the surface of the sea close to the horizon. Within minutes it had resolved itself into the most awe-inspiring sight that Ross had ever seen.
Next to his grass, that is.
Spaced out in perfect line abreast at intervals of half a mile, close on one hundred long, low, angular ships battered their way through the long Pacific swell like some gigantic battle fleet. Five hundred feet long, excessively low in the water, their superstructures covered with a random outgrowth of bumps, girders and angular projections, they were like no ships that history had ever seen. Devoid of such purely human necessities as decks, ports and lifeboats, their bizarre aspect was perhaps explained by the fact that they were ships which sailed rather than ships which were being sailed. Their wakes boiled and spread dazzlingly astern as if each ship were towing a thin white fan, until the sea turned almost to milk before the turbulence died. One hundred ships, identical but for the numerals painted on their bows, all holding a formation which would have sent the most exacting admiral in history into paroxysms of joy.
"The Pacific search fleet," Sister explained. "They are equipped with every method of underwater detection mentioned in the literature available to us, together with some which seemed to us to be a logical development of that data. They are accompanied, at a depth of five hundred feet, by ten auxiliary vessels capable of making a close investigation of any find down to a depth of one mile. Below that their pressure hulls implode and special equipment is necessary."
"Let's go down for a closer look," said Ross.
For half an hour he flew up and down that tremendous line of ships, communicating with some, but often just staring spellbound at the breathtaking perspective and at the way they seemed to even pitch and roll with the waves in unison. He, Ross, had been responsible for bringing this vast fleet into existence, and the thought made him feel a little drunk. He had a sudden urge to make them re-form into triple lines ahead, or concentric circles, or to make them spell out his name across fifty miles of ocean, but conquered it. Then shortly afterward Sister suggested that they fly southwest; she wanted to show him the interplanetary search project…
That also was a happy, exciting day, but his pleasure was being spoiled by a constant and growing restlessness. He wanted to get back to work and Sister wouldn't let him. If he tried to give instructions to some of the search robots Sister countermanded them, and if he asked for detailed reports on anything she stopped that, also, with the brisk reminder that he was on vacation. Hitherto the robot had treated him in one of two ways — as a patient, when she didn't do anything he told her, or as the Boss who was obeyed implicitly. Now she had seemingly developed a third alternative in which she did some of the things he asked and argued him out of the rest. At first he had suspected a malfunctioning which might have been due to the absence of Sister's data-storage trailer — he had thought that she had left it behind because of its awkwardness inside the aircraft. But then Sister informed him that she had not had to use the thing for the past ten thousand years, that sub-miniaturization and new data-indexing techniques had rendered it obsolete.
And so for two weeks Ross lazed and swam and collected a suntan on all the famous beaches of the world, until Sister indicated that he was fit to resume work by saying, "The search reports are kept at the hospital, sir. Do you wish to return?"
Again happily, Ross went back to work. Except for short breaks when he swam or went for a walk across the valley, all his time was spent in an enlarged control room which he had ordered built overlooking the sea. Between watching pictures relayed from search subs on the ocean beds or gray, static-riddled views of the lunar Alps, he worked at bringing himself up to date.
The land surfaces of the planet had been searched, thoroughly, to within a few hundred miles of the poles. One thousand, seven hundred and fifty-eight underground installations had been discovered and examined, which included launching bases, hospitals, underground towns and single residences, and mines converted into bomb shelters. In the sea seventy-two military or naval establishments had been examined up to the present, but two thirds of the Pacific and much of the Indian and South Atlantic Oceans had yet to be searched. So far three bases had been discovered on the moon, but none of them had been able to survive the warheads sent against them.
The search had uncovered vast quantities of usable metal, all of which had been salvaged, and many functioning robots and other servomechanisms of the nonthinking type. Millions of books of all kinds, engineering blueprints and various pictorial forms of data had been scanned, absorbed and stored in special memory banks, where they could be reproduced at will. As a result of this his robots had become much more adaptable, and gained tremendously in initiative. Now his most general and loosely worded instructions, even wishes he had left uncompleted, would be acted upon correctly and as quickly as was possible.
Altogether a tremendous achievement. But on the negative side…
No human survivors had been found, no animal life of any kind. Birds that flew, insects that crawled, worms that burrowed: none. The sea, lifeless.
Looking out of his dome, Ross began to hate the grass which rolled away on three sides of him. Apart from himself, it was the only thing which was originally alive oh the whole planet, and the only thing which he had gained by his last sleep was a well-stocked larder.
He took to wandering about the valley and throwing himself down on the grass at a different spot each day. He would lie for hours at a time, staring at the sky and praying just one spider or earwig or ladybird would crawl across his arm or leg. He began speaking to the robots less and less, which distressed Sister considerably. She began looking for ways and means of interesting him, and one day she actually succeeded.
"One of the robots we salvaged is a Tailor, sir," she said brightly as Ross was about to set out on another aimless walk. "It had occurred to me that you might like something more functional than the bed linen to wear."
Three hours later Ross found himself climbing into his first proper clothes in more than forty thousand years. As he stood before the mirror, resplendent in the tropical whites of a naval captain, Ross thought that it was just his luck that the robot had been a military Tailor. But the whites did set off his tan to advantage. If Alice could have seen him now…
"You've made this from bedsheets, too," said Ross harshly, to break a painful train of thought. "Try dyeing the stuff. And if you make it with an open collar, don't forget the shirt and tie to go with it, otherwise it would look ridiculous."
"Yes, sir," said the Tailor and Sister in unison. The Tailor moved off and Sister asked, "Is there anything else, sir?"
Ross was silent for a moment; then he said, "I'm fed up, bored, I'd like to go to the moon."
"I'm sorry, sir," Sister replied, and explained that the accelerations used would be instantly fatal to a human being, that radiation from the vessel's power unit would kill him within a few hours, and that there were other hazards, both radiation and meteoric, which they had no means of guarding him against. For the last human being, space travel was too risky.
"In that case," said Ross carefully, "I think I should go into Deep Sleep again."
"For how long, sir? And what reason?"
Forever, Ross felt like saying, but he knew that if he did Sister would start treating him like a patient again. He had a good reason — or excuse, rather — for wanting to undergo suspended animation again. The idea had come during one of his many despairing hours lying in the grass, and the funny thing was that it just might work despite being only an excuse.
He said: "There is no longer any hope of finding human survivors, in space, under the sea, in or out of Deep Sleep, and it is foolish to pretend that there is. My only purpose must be to bring intelligent organic life back to this planet, and for that we must seed the oceans. Life began in the seas and it may do so again. However, the only organic material available in quantity is the grass, so here is what I want done.
"First choose a strain which flourishes in swampland," he continued quickly, "and gradually increase the depth of water until it grows completely submerged, then gradually replace the fresh water with an increasingly saline solution. Replace soil with sand, and ultimately transplant into shallow sea water. I know that I'm trying to make evolution run backward, but there is a chance that a strain of sea grass might adapt into a mobile life form, and eventually develop intelligence.
