Arthur Clarke - Earthlight

Jamieson screwed up the wrappings and tossed them into the waste bin. He glanced at the chronometer, then swung himself up into the driving seat. “Time to get moving again,” he said. “We’re falling behind schedule.”

From the Straight Range they swung southeast, and presently the great headland of Promontory Laplace appeared on the skyline. As they rounded it, they came across a disconcerting sight—the battered wreck of a tractor, and beside it a rough cairn surmounted by a metal cross. The tractor seemed to have been destroyed by an explosion in its fuel tanks, and was an obsolete model of a type that Wheeler had never seen before. He was not surprised when Jamieson told him it had been there for almost a century; it would still look exactly the same a million years from now.

As they rolled past the headland, the mighty northern wall of the Sinus Iridum —the Bay of Rainbows—swept into view. Eons ago the Sinus Iridum had been a complete ring mountain— one of the largest walled-plains on the Moon. But the cataclysm which had formed the Sea of Rains had destroyed the whole of the southern wall, so that only a semicircular bay is now left. Across that bay Promontory Laplace and Promontory Heraclides stare at each other, dreaming of the day when they were linked by mountains four kilometers high. Of those lost mountains, all that now remain are a few ridges and low hillocks.

Wheeler was very quiet as the tractor rolled past the great cliffs, which stood like a line of titans full-face toward the Earth. The green light splashing down their flanks revealed every detail of the terraced walls. No one had ever climbed those heights, but one day, Wheeler knew, men would stand upon their summits and stare out in victory across the Bay. It was strange to think that after two hundred years, there was so much of the Moon untrodden by human feet, and so many places that a man must reach with nothing to aid him but his own exertions and skill.

He remembered his first glimpse of the Sinus Iridum, through the little homemade telescope he had built when he was a boy. It had been nothing more than two small lenses fixed in a cardboard tube, but it had given him more pleasure than the giant instruments of which he was now the master.

Jamieson swung the tractor round in a great curve, and brought it to a halt facing back toward the west. The line they had trampled through the dust was clearly visible, a road which would remain here forever unless later traffic obliterated it.

“The end of the line,” he said. “You can take over from here. She’s all yours until we get to Plato. Then wake me up and I’ll take her through the mountains. Good night.”

How he managed it, Wheeler couldn’t imagine, but within ten minutes Jamieson was asleep. Perhaps the gentle rocking of the tractor acted as a lullaby, and he wondered how successful he would be in avoiding jolts and jars on the way home. Well, there was only one way to find out… He aimed carefully at the dusty track, and began to retrace the road to Plato.

It was bound to happen sooner or later, Sadler told himself philosophically, as he knocked at the director’s door. He had done his best, but in work like this it was impossible to avoid hurting someone’s feelings. It would be interesting, very interesting, to know who had complained…

Professor Maclaurin was one of the smallest men Sadler had ever seen. He was so tiny that some people had made the fatal mistake of not taking him seriously. Sadler knew better than this. Very small men usually took care to compensate for their physical deficiencies (how many dictators had been of even average height?) and from all accounts Maclaurin was one of the toughest characters on the Moon.

He glared at Sadler across the virgin, uncluttered surface of his desk. There was not even a scribbling pad to break its bleakness—only the small panel of the communicator switchboard with its built-in speaker. Sadler had heard about Mac-laurin’s unique methods of administration, and his hatred of notes and memoranda. The Observatory was run, in its day-today affairs, almost entirely by word of mouth. Of course, other people had to prepare notices and schedules and reports— Maclaurin just switched on his mike and gave the orders. The system worked flawlessly for the simple reason that the director recorded everything, and could play it back at a moment’s notice to anyone who said, “But, sir, you never told me that !” It was rumored—though Sadler suspected this was a libel—that Maclaurin had occasionally committed verbal forgery by retrospectively altering the record. Such a charge, needless to say, was virtually impossible to prove.

The director waved to the only other seat, and started talking before Sadler could reach it.

“I don’t know whose brilliant idea this was,” he began, “but I was never notified that you were coming here. If I had been, I would have asked for a postponement. Although no one appreciates the importance of efficiency more than I do, these are very troubled times. It seems to me that my men could be better employed than by explaining their work to you—particularly while we are coping with the N. Draconis observations.”

“I’m sorry there was a failure to inform you, Professor Mac-laurin,” Sadler replied. “I can only assume that the arrangements were made while you were en route to Earth.” He wondered what the director would think if he knew how carefully matters had been arranged in this precise manner. “I realize that I must be something of a nuisance to your staff, but they have given me every assistance and I’ve had no complaints. In fact, I thought I was getting on rather well with them.”

Maclaurin rubbed his chin thoughtfully. Sadler stared in fascination at the tiny, perfectly formed hands, no larger than those of a child.

“How much longer do you expect to be here?” the director asked. He certainly doesn’t worry about your feelings, Sadler told himself wryly.

“It’s very hard to say—the area of my investigation is so undefined. And it’s only fair to warn you that I’ve scarcely started on the scientific side of your work, which is likely to present the greatest difficulties. So far I have confined myself to Administration and Technical Services.”

This news did not seem to please Maclaurin. He looked like a small volcano working up to an eruption. There was only one thing to do, and Sadler did it quickly.

He walked to the door, opened it swiftly, looked out, then closed it again. This piece of calculated melodrama held the director speechless while Sadler walked over to the desk and brusquely flicked down the switch on the communicator.

“Now we can talk,” he began. “I wanted to avoid this, but I see it’s inevitable. Probably you’ve never met one of these cards before.”

The still flabbergasted director, who had probably never before in his life been treated like this, stared at the blank sheet of plastic. As he watched, a photograph of Sadler, accompanied by some lettering, flashed into view—then vanished abruptly.

“And what,” he asked when he had recovered his breath, “is Central Intelligence? I’ve never heard of it.”

“You’re not supposed to,” Sadler replied. “It’s relatively new, and highly unadvertised. I’m afraid the work I’m doing here is not exactly what it seems. To be brutally frank, I could hardly care less about the efficiency of your establishment, and I completely agree with all the people who tell me that it’s nonsense to put scientific research on a cost-accounting basis. But it’s a plausible story, don’t you think?”

“Go on,” said Maclaurin, with dangerous calm.

Sadler was beginning to enjoy himself beyond the call of duty. It wouldn’t do, however, to get drunk with power…
