When the four-power crew proudly displayed their trophies back on the Gateway asteroid, they created an immense stir. None of the three looked like a major technological breakthrough. Nevertheless, if such things could be found, then there were certainly others-and no doubt things that would be of a lot more practical value.
That was when the interstellar gold rush began in earnest.
It was a long time before anyone got that lucky again. Overall, the statistics on missions out of the Gateway asteroid showed that four out of five trips came back with nothing to show but some pictures and instrument readings. Fifteen percent never came back at all. It was only one ship out of twenty that brought back any tangible piece of Heechee technology, and most of those things were
only curiosities-but the very few that were more than curiosities were treasures beyond price.
They were few and far between, to be sure. The exploration of Venus had shown that was probable, for in all the hundreds of miles of Heech~e tunnels under the surface of the planet Venus no more than a dozen gadgets had been found.
To be sure, some of those meant big profits for those who learned to copy them. The anisokinetic punch was a marvel. Hammer it on one end, and the force of the blow came out at the side. What was even more marvelous was that scientists managed to figure out how it worked, and its principle had applications in every area of construction, manufacture, and even home repair. The fire-pearls were a mystery. So were the so-called prayer fans.
Then, of course, humans reached the Gateway asteroid, and that fleet of ships was the biggest treasure trove of all. But all there was on the asteroid were the ships themselves. The ships were empty of anything but their operating gear. The whole asteroid was empty, almost surgically clean . . . as though the Heechee had deliberately left the ships but removed everything else that could be of value.
Over a period of twenty years and more the Gateway explorers went out to seek whatever could be found. They came back with pictures and stories, and kinds of living things and minerals; but of Heechee artifacts they found very few.
That was why so many Gateway prospectors died poor-or just died.
MISSION TOOLBOX
Some also died rich, without knowing they had become rich. That was the case in one of the biggest finds. Unfortunately, it did three of its five discoverers little good, because they did not survive the trip.
The mission started with three Austrians, two brothers and an uncle, using the last of an inheritance to pay their way to Gateway. They were determined to ship out only in an armored ship. As the only such vessel available was a Five, at the last minute they recruited a South American, Manuel de los Fintas, and an American, Sheri Loffat, to go with them.
They reached a planet; they landed on the planet; they found nothing much there. But their instruments showed Heechee metal somewhere around, and they tracked it down.
It was a lander. It had been abandoned there, heaven knew when. But it was not empty.
The biggest thing they found in the lander was a stack of Heechee metal hexagonal boxes, not more than half a meter across and less than half that tall, weight twenty-three kilograms. They were
tools. Some of the items were familiar, and useless as far as anyone had been able to tell: almost a dozen little prayer fans of the kind that littered so many Heechee tunnels and artifacts. But there were also things like screwdrivers but with flexible shafts; things like socket wrenches but made out of some soft material; things that resembled electrical test probes but turned out to be spare parts for other Heechee machines.
It was a grand success. They wound up millionaires-or, at least, the survivors did.
That find was lying right on the surface of the planet. But before long the Gateway prospectors learned that planet surfaces were not the most likely places to look for examples of Heechee treasures. Under the surface was much, much richer.
One thing was clear early on about the vanished Heechee: they liked tunnels. The Heechee tunnels that honeycombed parts of the planet Venus weren't unique. As explorations retraced the old interstellar trails they found examples of them everywhere the Heechee had gone. The inside of the Gateway asteroid was a maze of tunnels; so were the "other Gateways" that turned up as the explorations progressed. Nearly every planet the Heechee had left any
