[Chapter 3]
In retrospect, events moved much faster than reason would suggest. The first signal from space had been received on a Friday. At that time—when the first flutings were picked up by a tape recorder on Kalua—the world had settled down to await the logical consequences of its history. It was not a comfortable settling-down, because the consequences were not likely to be pleasant. Earth was beginning to be crowded, and there were whole nations whose populations labored bitterly with no hope of more than subsistence during their lifetime, and left a legacy of equal labor and scarcer food for their descendants. There were hydrogen bombs and good intentions, and politics and a yearning for peace, and practically all individual men felt helpless before a seemingly merciless march of ominous events. At that time, too, nearly everybody worked for somebody else, and a large part of the employed population justified its existence by the length of time spent at its place of employment. Nobody worried about what he did there.
In the richer nations, everybody wanted all the rewards earned for them by generations gone by, but nobody was concerned about leaving his children better off. An increasingly smaller number of people were willing to take responsibility for keeping things going. There'd been a time when half of Earth fought valiantly to make the world safe for democracy. Now, in the richer nations, most men seemed to believe that the world had been made safe for a four-card flush, which was the hand they'd been dealt and which nobody tried to better.
Then the signals came from space. They called for a showdown, and very few people were prepared for it. Eminent men were called on to take command and arrange suitable measures. They immediately acted as eminent men so often do; they took action to retain their eminence. Their first instinct was caution. When a man is important enough, it does not matter if he never does anything. It is only required of him that he do nothing wrong. Eminent figures all over the world prepared to do nothing wrong. They were not so concerned to do anything right.
Burke, however, was not important enough to mind making a mistake or two. And there were other non-famous people to whom the extra-terrestrial sounds suggested action instead of precautions. Mostly they were engineers with no reputations to lose. They'd scrabbled together makeshift equipment, ignored official channels, and in four days—Friday to Monday—they had eight hundred kilowatts ready to fling out toward emptiness, in response to the signal from M-387.
The transmission they'd sent out was five minutes long. It began with a re-transmission of part of the message Earth had received. This plainly identified the signal from Earth as a response to the cryptic flutings. Then there were hummings. One dot, two dots, three, and so on. These hummings assured whoever or whatever was out yonder that the inhabitants of Earth could count. Then it was demonstrated that two dots plus two dots were known to equal four dots, and that four and four added up to eight. The inhabitants of Earth could add. There followed the doubtless interesting news that two and two and two and two was eight. Humanity could multiply.
Arithmetic, in fact, filled up three minutes of the eight-hundred-kilowatt beam-signal. Then a hearty human voice—the president of a great university—said warmly:
"Greetings froth Earth! We hope for splendid things from this opening of communication with another race whose technical achievements fill us with admiration."
More flutings repeated that the Earth signal was intended for whoever or whatever used flutelike sounds for signaling purposes, and the message came to an end with an arch comment from the university president: "We hope you'll answer!"
When this elaborate hodge-podge had been flung out to immensity, the prominent persons who'd devised it shook hands with each other. They were confident that if intelligent beings did exist where the mournful musical notes came from, interplanetary or interstellar communication could be said to have begun. The engineers who'd sweated together the equipment simply hoped their signal would reach its target.
