He tried to lift his fork. He put it down again.
"I can't eat," he said abruptly.
Huyghens made no comment. He finished his own meal, scowling. He rose and put the plates into the top of the cleaner. There was a whirring. He took them out of the bottom and put them away.
"Let me see those reports, eh?" he asked dourly. "I'd like to see what sort of a set-up they had—those robots."
Roane hesitated and then opened his traveling bag. There was a microviewer and reels of films. One entire reel was labeled "Specifications for Construction, Colonial Survey" which would contain detailed plans and all requirements of material and workmanship for everything from desks, office, administrative personnel, for use of, to landing grids, heavy-gravity planets, lift-capacity one hundred thousand Earth-tons. But Huyghens found another. He inserted it and spun the control swiftly here and there, pausing only briefly at index frames until he came to the section he wanted. He began to study the information with growing impatience.
"Robots, robots, robots!" he snapped. "Why don't they leave them where they belong—in cities to do the dirty work, and on airless planets where nothing unexpected ever happens! Robots don't belong in new colonies! Your colonists depended on them for defense! Dammit, let a man work with robots long enough and he thinks all nature is as limited as they are! This is a plan to set up a controlled environment! On Loren Two! Controlled environment—" He swore, luridly. "Complacent, idiotic, desk-bound half-wits!"
"Robots are all right," said Roane. "We couldn't run civilization without them."
"But you can't tame a wilderness with 'em!" snapped Huyghens. "You had a dozen men landed, with fifty assembled robots to start with. There were parts for fifteen hundred more—and I'll bet anything I've got that the ship-contacts landed more still."
"They did' admitted Roane.
"I despise 'em," growled Huyghens. "I feel about 'em the way the old Greeks and Romans felt about slaves. They're for menial work—the sort of work a man will perform for himself, but that he won't do for another man for pay. Degrading work!"
"Quite aristocratic!" said Roane with a touch of irony. "I take it that robots clean out the bear quarters downstairs."
"No!" snapped Huyghens. "I do! They're my friends! They fight for me! They can't understand the necessity and no robot would do the job right!"
He growled, again. The noises of the night went on outside. Organ tones and hiccupings and the sound of tack hammers and slamming doors. Somewhere there was a singularly exact replica of the discordant squeaking of a rusty pump.
"I'm looking," said Huyghens at the micro-viewer, "for the record of their mining operations. An open-pit operation wouldn't mean a thing. But if they had driven a tunnel, and somebody was there supervising the robots when the colony was wiped out, there's an off-chance he survived a while."
Roane regarded him with suddenly intent eyes.
"And—"
"Dammit," snapped Huyghens, "if so I'll go see! He'd…they'd have no chance at all, otherwise. Not that the chance is good in any case!"
Roane raised his eyebrows.
"I'm a Colonial Survey officer," he said. "I've told you I'll send you to prison if I can. You've risked the lives of millions of people, maintaining non-quarantined communication with an unlicensed planet. If you did rescue somebody from the ruins of the robot colony, does it occur to you that they'd be witnesses to your unauthorized presence here?"
Huyghens spun the viewer again. He stopped. He switched back and forth and found what he wanted. He muttered in satisfaction: "They did run a tunnel!" Aloud he said, "I'll worry about witnesses when I have to."
He pushed aside another cupboard door. Inside it were the odds and ends a man makes use of to repair the things about his house that he never notices until they go wrong. There was an assortment of wires, transistors, bolts, and similar stray items that a man living alone will need. When to his knowledge he's the only inhabitant of a solar system, he especially needs such things.
"What now?" asked Roane mildly.
"I'm going to try to find out if there's anybody left alive over there. I'd have checked before if I'd known the colony existed. I can't prove they're all dead, but I may prove that somebody's still alive. It's barely two weeks' journey away from here! Odd that two colonies picked spots so near!"
He absorbedly picked over the oddments he'd selected. Roane said vexedly:
"Confound it! How can you check whether somebody's alive some hundreds of miles away—when you didn't know he existed half an hour ago?"
Huyghens threw a switch and took down a wall panel, exposing electronic apparatus and circuits behind. He busied himself with it.
"Ever think about hunting for a castaway?" he asked over his shoulder. "There's a planet with some tens of millions of square miles on it. You know there's a ship down. You've no idea where. You assume the survivors have power—no civilized man will be without power very long, so long as he can smelt metals!—but making a space beacon calls for high-precision measurements and workmanship. It's not to be improvised. So what will your shipwrecked civilized man do, to guide a rescue ship to the one or two square miles he occupies among some tens of millions on the planet?"
Roane fretted visibly.
"What?"
"He's had to go primitive, to begin with," Roane explained. "He cooks his meat over a fire, and so on. He has to make a strictly primitive signal. It's all he can do without gauges and micrometers and very special tools. But he can fill all the planet's atmosphere with a signal that searchers for him can't miss. You see?"
Roane thought irritably. He shook his head.
"He'll make," said Huyghens, "a spark transmitter. He'll fix its output at the shortest frequency he can contrive—it'll be somewhere in the five-to-fifty-meter wave-band, but it will tune very broad—and it will be a plainly human signal. He'll start it broadcasting. Some of those frequencies will go all around the planet under the ionosphere. Any ship that comes in under the radio roof will pick up his signal, get a fix on it, move and get another fix, and then go straight to where the castaway is waiting placidly in a hand-braided hammock, sipping whatever sort of drink he's improvised out of the local vegetation."
Roane said grudgingly:
"Now that you mention it, of course—"
"My space phone picks up microwaves," said Huyghens, "I'm shifting a few elements to make it listen for longer stuff. It won't be efficient, but it will pick up a distress signal if one's in the air. I don't expect it, though."
He worked. Roane sat still a long time, watching him. Down below, a rhythmic sort of sound arose. It was Sourdough Charley, snoring. He lay on his back with his legs in the air. He'd discovered that he slept cooler that way. Sitka Peter grunted in his sleep. He was dreaming. In the general room of the station Semper, the eagle, blinked his eyes rapidly and then tucked his head under a gigantic wing and went to sleep. The noises of the Loren Two jungle came through the steel-shuttered windows. The nearer moon—which had passed overhead not long before the ringing of the arrival bell—again came soaring over the eastern horizon. It sped across the sky at the apparent speed of an atmosphere-flier. Overhead, it could be seen to be a jagged irregular mass of rock or metal, plunging blindly about the great planet forever.
Inside the station, Roane said angrily:
"See here, Huyghens! You've reason to kill me. Apparently you don't intend to. You've excellent reason to leave that robot colony strictly alone. But you're preparing to help, if there's anybody alive to need it. And yet you're a criminal—and I mean a criminal! There've been some ghastly bacteria exported from planets like Loren Two! There've been plenty of lives lost in consequence, and you're risking more! Why do you do it? Why do you do something that could produce monstrous results to other beings?"
