Astounding Stories of Super-Science, August 1930

Whence came the glow? Apparently from the very walls of the tunnel, or its roof; but surely from somewhere, surely from some secret place, whence it was diffused all over. "And Jaska," said Sarka, "the Moon, according to my father's researches, is literally honeycombed with craters like this one!" Again, as he thought, that strange, sudden cessation of the clucking of the Gnomes. Whither were they leading them? It was plain to be seen that the Gnomes were heading for some destination, almost herding Sarka and Jaska toward it. Capering creatures, who behaved witlessly, yet were far from witless. If Sarka were not sadly mistaken, these were Moon-men--and women, too, perhaps, since he could not tell the sex of them--and those gleaming cubes were their outer guards, perhaps slaves. If the cubes were really of metal--they had felt warm to Sarka's touch--then these Moon-men had gone further in science than Earthlings, as they had imbued at least some metals, or stones, with intelligence sufficiently advanced for them to perform actions independently of their masters' wills. Sarka, too, was remembering another thing: that he had touched one of these Gnomes, to remove it from Jaska--and had felt a distinct shock that was patently electrical! The bluish glow was increasing, becoming more soft and mellow, shading gradually into golden, as they advanced--shading still as they preceded until it was almost white, almost blinding, in its radiance. Then, of a sudden, the clucking of the Gnomes ended, and the creatures ceased their capering, fell into something that might have been an ordered military formation, and with Jaska and Sarka in the midst of them, moved straight toward a broad expanse of the tunnel wall, in the face of which appeared three long lines, deeply cut in the shape of a triangle.
