"It's big, Les," he said. "It's got to be! An expedition came here to investigate the Moon--it couldn't be any more recently than sixty million years ago, if it was from as close as Mars, or the Asteroid Planet! Two adjacent worlds were competing, then, the scientists know. Both were smaller than the Earth, cooled faster, bore life sooner. Which sent the party? I saw where there rocket ship must have stood--a glassy, spot where the dust was once fused!... From all the markings, they must have been around for months. Nowhere else on the Moon--that I ever heard of--is there anything similar left. So maybe they did most of their survey work by gliding, somehow, above the ground, not disturbing the dust... I think the little indentations we saw look Martian. That would be a break! Mars still has weather. Archeological objects wouldn't stay new there for millions of years, but here they would! Rodan is right--he's got something that'll make him famous!" "Yes--I think I'll have a devil-killer and hit the sack, Frank," Lester said. "Oh--all right," Frank agreed wearily. "Me, likewise." Frank awoke naturally from a dreamless slumber. After a breakfast of eggs that had been a powder, Lester and he were at the diggings, sifting dust for the dropped and discarded items of an alien visitation. Thus Frank's job began. In the excitement of a hunt, as if for ancient treasure, for a long time, through many ten hour shifts, Frank Nelsen found a perhaps unfortunate Lethe of forgetfulness for his worries, and for the mind-poisoning effects of the silence and desolation in this remote part of the Moon. They found things, thinly scattered in the ten acre area that Rodan meant tediously to sift. The screws and nuts, bright and new, were almost Earthly. But would anyone ever know what the little plastic rings were for? Or the sticks of cellulose, or the curved, wire device with fuzz at the ends? But then, would an off-Earth being ever guess the use of--say--a toothbrush or a bobbypin? The metal cylinders, neatly cut open, might have contained food--dried leaf-like dregs still remained inside. There were small bottles made of pearly glass, too--empty except for gummy traces. They were stoppered with a stuff like rubber. There were also crumpled scraps, like paper or cellophane, most of them marked with designs or symbols. After ten Earth-days, in the lunar afternoon, Frank found the grave. He shouted as his brushing hands uncovered a glassy, flexible surface. Rodan took charge at once. "Back!" he commanded. Then he was avidly busy in the pit, working as carefully as a fine jeweller. He cleared more dust away, not with a trowel, not with his gloved fingers, but with a little nylon brush. The thing was like a seven-pointed star, four feet across. And was the ripped, transparent casing of its body and limbs another version of a vacuum armor? The material resembled stellene. As in an Archer, there were metal details, mechanical, electronic, and perhaps nuclear.
