"By what right," it demanded, "do you invade the room of scientific composition? Why are you not in your cages? You know you will receive the punishment of the yellow lights in the greater degree for this unauthorized invasion. Save yourself further punishment now by retiring quietly. You can take my life, it is true, but I am old and my life is of no value. Think not that I am the only Lassan in the universe."

"Sorry," Sherman gave him back, "but this is a rebellion. You are not familiar with the history of this planet, or you would know that Americans can't be anybody's slaves. Let us go in peace and we will let you return to your own planet."

"Let us go!" came the Lassan's answer. "Your obstinate presumption surprises me. Do you think that the Lassans of Rigel, the highest race in the universe will let go where they have once grasped?"

"You will or we'll jolly well make you," replied the American. "Do you think your silly green globes are going to do you any good? The last one fell beside us tonight."

Sherman could sense the sudden wave of panic in the Lassan's thought at this unexpected answer. He had evidently assumed that they were from the underground labor battalions and were not familiar with events outside. But he rallied nobly.

"And do you imagine, foolish creature of a lower race, that the green globes are our last resource? Even now I have perfected a device that will wipe your miserable people from the planet. But if it did not, rather would we Lassans perish in the flames of a ruined world than abandon a task once undertaken; we who can mold the plastic flesh to enduring metal and produce machines that have brains; we who can control the great substance that underlies all life and matter."

"Well, here's one task you're going to abandon," Sherman thought back. "We, who can call lightning from the skies, are going to give you a terrible sock on the—trunk, if you don't. If you doubt it try and find how many Lassans live after today's battle. Go on back where you came from. You're not wanted in this world."

"You know, or should know, the law of evolution," replied the Lassan. "The weaker and less intelligent must ever give way before the stronger. By the divine right of—" his flow of thought stopped suddenly, changed to a wild tumult of panic. Sherman looked up. Round the rim of the blue dome, where it stood above the hangings, a string of lights was winking oddly, in a strange, uneven rhythm. "God of the Lassans, deliver us!" the thought that reached his own was saying. "The tanks are broken—the light is loose!" Then suddenly his mind was closed and when it opened again it had taken on a new calmness and dignity and a certain god-like strength.

"I do not know how or where," it told Sherman, "but an accident has happened. Perhaps an accident produced by your strange and active race. The connections have broken; the tanks of the substance of life in the bowels of this mountain have broken and the whole is set free. It is hard to see the labor of centuries thus destroyed; to see you, creatures of a lower race, inherit a world so divinely adapted to the rule of intelligence.

"For in this accident the whole of our race must perish if you have told the truth about the destruction of our green globes. We called in all the Lassans from your world for the work of the destruction of your armies. Yes, you told the truth. Your mind is open, I can see it. We are lost.... There is no hope remaining; it means destruction or the metal metamorphosis for every living Lassan, and there will be none to endow them with the life in metal we have given you.
