Sciences that he'd been dreaming signals like the ones that now agitated humanity. It was too absurd. But it was unthinkable for a person of Burke's temperament to do nothing. So he set to work in exactly the fashion of one of the crackpots he disliked.

Actually, the job should have been undertaken in ponderous secrecy by committees from various learned societies, official bureaus, and all the armed forces. There should have been squabbles about how the task was to be divided up, bitter arguments about how much money was to be spent by whom, violent disagreements about research-and-development contracts. It should have been treated as a program of research, in which everybody could claim credit for all achievements and nobody was to blame for blunders.

Burke could not command resources for so ambitious an undertaking. And he knew that as a private project it was preposterous. But he began the sort of preliminary labor that an engineer does before he really sets to work.

He jotted down some items that he didn't have to worry about. The wall-garden he'd made for Interiors, Inc., would fit neatly into whatever final result he got—if he got a final result. He had a manufacturing process available for glass-wool and plastics. If he could get hold of an inertia-controlled computer he'd be all set, but he doubted that he could. The crucial item was a memo he'd made from a memory of the dream weapon. It concerned certain oddly-shaped bits of metal, with fine wires wound eccentrically about them, which flew explosively to pieces when a current went through them. That was something to worry about right away.

At three o'clock in the morning, then, Burke routed out the laboratory notes on the small-sized metal-stamping machine he had designed for American Tool. He'd tried to do the job with magnets, but they flew apart. He'd wound up with blank cartridges to provide the sudden, explosive stamping action required, but the notes on the quasi-magnets were complete.

He went through them carefully. An electromagnet does not really attain its full power immediately after the current is turned on. There is an inductive resistance, inherent in a wound magnet, which means that the magnetism builds up gradually. From his memory of the elements in a transparent-plastic hand-weapon barrel, Burke had concluded that it was possible to make a magnet without inductive resistance. He tried it. When the current went on it went to full strength immediately. In fact, it seemed to have a negative-induction effect. But the trouble was that it wasn't a magnet. It was something else. It wound up as scrap.

Now, very reflectively, he plugged in a metal lathe and carefully turned out a very tiny specimen of the peculiarly-shaped magnetic core. He wound it by hand, very painstakingly. It was a tricky job. It was six o'clock Saturday morning when the specimen was finished. He connected the leads to a storage battery and threw the switch. The small object tore itself to bits, and the core landed fifteen feet from where it had been. Burke beamed.

He wasn't tired, but he wanted to think things over so he drove to a nearby diner and got coffee and a roll and reflected with satisfaction upon his accomplishment. At the cost of several hours' work he'd made a thing like a magnet, which wasn't a magnet, and which destroyed itself when turned on. As he drank his coffee, a radio news period came on. He listened.

The signals still arrived from space, punctually, seventy-nine minutes apart. At this moment, 6:30 A.M., they were not heard on the Atlantic coast, but the Pacific coast still picked them up and they were heard in Hawaii and again on the South Pacific island of Kalua.

Burke drove back to the plant. He was methodical, now. He reactivated the prototype wall-garden which he'd neglected while building the larger one for Interiors, Inc. The experimental one had been made in four sections so he could try different pumping systems and nutrient solutions. Now he set the pumps to work. The plants looked ragged, but they'd perk up with proper lighting and circulation of the hydroponic liquid.

Then he went into the plant's small office building and sat down with drawing instruments to modify the design of the magnetic core. At eleven he'd worked out a rough theory and refined the design, with curves and angles all complete. At four the next morning a second, modified magnet-core was formed and polished.

He'd heard the first newscast on Friday night. It was now early Sunday morning, and although he was tired, he was still not sleepy. He worked on doggedly, winding fine magnet wire on a noticeably complicated metal form. Just before sunrise he tested it.

When the current went on the wire windings seemed to swell. He'd held it in a small clamp while he tested it. The clamp overturned and broke the contact with the battery before the winding wire stretched to breaking-point. But it had not torn itself or anything else to bits.

He was suddenly enormously weary and bleary-eyed. To anyone else in the world, the consequence of this second attempt to make what he thought of as a negative-induction magnet would seem an absolute failure. But Burke now knew why the first had failed and what was wrong with the second. The third would work, just as the unfired hand-weapon of his dream would have worked. Now he could justify to himself the association of a recurrent dream with a message from outer space. The dream now had two points of contact with reality. One was the sounds from emptiness, which matched those in the dream. The other was the hand-weapon of the dream, whose essential working part now plainly did something unknown in a normal world.

But it would be impossible to pass on his information to anybody else. Too many crackpots have claimed too many triumphs. His actual, unpredictable technical achievement would have little chance of winning official acceptance. Especially since he would be considered a non-accredited source. Burke had a small business of his own. He had an engineering degree. But he had no background of learned futility to gain a hearing for what he now knew.

"Crackpots of the world, unite!" he muttered to himself.

He dragged himself out-of-doors to a cool, invigorating morning and drove somnolently to the diner he'd patronized before. The coffee he ordered was atrocious, but it waked him. He heard two truck drivers at the counter.

"It's baloney!" said one of them scornfully. "There ain't no people out there! We'd'a heard from them before if there was. Them scientists are crazy!"

"Nuts!" said the other earnestly. "One of their idle thoughts would crack your brain wide open, mac! They know what's up, and they're scared! If you wanna know, I'm scared too!"

"Of what?"

"Hell! Did you ever drive at night, and have all the stars come in pairs like snake-eyes—like little mean eyes, lookin' down at you an' despisin' you? You've seen that, ain't you? Whoever's signalin' could be lookin' down at us just like the stars do."

The first man grunted.

"I don't like it!" said the second man, fretfully. "If it was a man headin' out to go huntin' among the stars for somethin' he wanted, that's all right. That's like a man goin' huntin' in the woods with a gun. But I don't like somebody comin' our way from somewhere else. Maybe he's huntin' us!"

The two drivers paid for their coffee and went out. And Burke reflected wryly that the second man had, after all, expressed a universal truth. We humans do not like to be hunted. The passion with which a man-killing wild beast is pursued comes from human vanity. We do not like the idea that any other creature can be better than we are. It is highly probable that if we ever have to face a superior race, we will die of it.

So Burke went back to the plant and began to make yet another of the peculiarly wound magnets-which-were-not-magnets. This was to have three of the odd-shaped cores, formed in line, of a single piece of Swedish iron. As the windings were put on they'd be imbedded in
