The light of the cube made the interior of the aircar as light as day, and Sarka was struck at once with another phenomenon. He could see through the sides of the car in any direction. And what he saw filled him with a sudden fear! Out of the crater poured myriads of the Gnomes, and up the sides of it came myriads of the gleaming cubes, all racing toward the cars. "Get back! Get back!" he commanded the Gnomes and the cubes. At the same time he issued his commands to the cube within his own car, and to the cubes which by now were inside the other aircars, realizing that the cubes themselves were the motive power of the aircars--and that his will was the will of these individual cubes. "Fly at once! Fly outward at top speed toward the Earth!" Instantly, as though a single signal had started all the cars, a dozen aircars rose majestically from the crater, while Sarka studied the Gnomes and the cubes in turmoil on the rim. He noted then, a strange circumstance: that when he commanded the Gnomes and the pursuing cubes to keep back, they hesitated, dazedly, as though they did not know whether to advance or to retreat; that when he merely watched them, they came on. He laughed aloud at this measuring of mental swords with Luar, and with Dalis. For he could sense the conflict very plainly. She commanded the Gnomes and the cubes to attack, he commanded them to retreat, and they remained undecided, like people drawn between two extremities, and uncertain which direction to take. Upward, side by side now, floated the aircars of the Moon, and in the forepeak of each, one of the gleaming cubes, like--like anti-gravitational ovoids of the Moon! At the fast falling rim of the crater boiled the Gnomes and the cubes, stirring and tumbling, hampered by their very numbers, as they tried to attack at will of Luar and retreated in confusion at the will of Sarka. Then there was Jaska beside Sarka, her face fearful, as he pointed off across the gloomy expanse of the Moon. From all sides, from all directions, from other craters which these two had not even seen, came scores and hundreds of the monster cars! They had beaten Luar and Dalis but for a moment, then! Now, at her command, the countless other aircars were coming in to head them off, to fight them back to the surface of the Moon. It would be a race against time, and against death. But of at least a dozen of the aircars, Sarka was master, and he did not fear the issue. That strange exaltation which the white flames had given him filled him with a confidence that nothing could shake. He shot a thought at the gleaming cube in the forepeak. "Faster! Faster! There is no limit to your speed! Faster! Faster! Even faster!" Instantly the Moon seemed literally to drop away beneath the dozen aircars which carried the Radiant People, while the aircars of Luar and of Dalis fell hopelessly behind.
