Grushenko barked a laugh. "How long do you expect them not to know about us? Let us learn what we can while we can." He was a heavy-muscled man, affecting the shaven pate of an Army officer; he made no bones about being an unreconstructed sovietist, he had killed two mutineers before they overpowered him and since then his cooperation was surly. But now Levine nodded a bespectacled head and put in: "He's right, Eben. We can take a walky-talky, and the jet's transmitter will relay back to camp." He lifted a rifle from its rack and sighed. "I had hoped never to carry one of these again." "It may not be necessary," said Holbrook in a desperate voice. "Those creatures ... they don't live here ... they can't! Why couldn't we make an ... agreement—" "Perhaps." A faraway light flickered in Grushenko's pale eyes. "Yes, once we learn their language ... it might very well be possible, mutual interest and—After all, their level of technology implies they have reached the soviet stage of development." "Oh, come off it," said Levine in English. Holbrook used a downblast to land the jet in a meadow, a few kilometers from the alien diggings. If the craft had not been noticed—and it had gone over very quickly—its crew should be able to steal up and observe.... He was glad of the imposed silence as they slipped among great shadowy trees; what could he have said, even to Levine? That was how it always went, he thought in a curious irrelevant anguish. He was not much more nervous than the next man, but he had no words at the high moments. His tongue knotted up and he stood like a wooden Indian under the gaze of Ekaterina Ivanovna. At the end of their walk, they stood peering down a slope through a screen of brush. The land was raw and devastated, it must have been worked for centuries. Holbrook remembered a survey report: curious formations spotted all over the planet, pits hundreds of meters deep. Yes, they must be the grass-grown remnants of similar mines, exhausted and abandoned. How long had the aliens been coming here? The automatons which purred about, digging and carrying, grinding, purifying, loading into the incredibly big and sleek blue spaceships, were such as no one on Earth had ever built. Levine's voice muttered to a recorder beyond the mountains, "Looks like rare-earth ores to me. That suggests they've been civilized long enough to use up their home planet's supply, which is one hell of a long time, my friends." Holbrook
