"Ah! Patriotism! A good lure for the ignorant masses, that thing they call patriotism. For rulers, a good mask with which to hide their unscrupulous schemes. That's all it is, Georg Brende. Cannot you give me a better reason? You think perhaps I am not sincere? You think I would not share longevity with you—that I would play you false?"

"No," Georg declared. "But my father's work was for the people. I'm not talking patriotism—only humanitarianism. The strife, suffering in our worlds—you would avoid it yourself—and gloat while others bore it. You——"

"Youth!" Tarrano interrupted. "Altruism! It is very pretty in theory—but quite nonsensical. Man lifts himself—the individual must look out for himself—not for others. Each man to his destiny—and the weak go down and the strong go up. It is the way of all life—animal and human. It always has been—and it always will be. The way of the universe. You are very young, Georg Brende."

"Perhaps," Georg said, and fell silent.

Tarrano abruptly rose to his feet. "Calm thought is better than argument. You have imagination—you can picture what I offer. Think it over. And if youth is your trouble——" His eyes were twinkling. "I shall have to wait until you grow up. We have a long road to travel—empires cannot be built in a day."

He paused before Elza with a grave, dignified bow. "Goodnight, Lady Elza."

"Goodnight," she said.

He left us. We stood listening to his footsteps as he quietly descended the tower incline. At his summons, the barrage was lifted. He went out. From the balcony we saw him cross the spider bridge, with Argo at his heels. As they vanished into the yawning mouth of an arcade beyond the bridge, again came that rose-glow in the other tower. We saw again the girl with flowing white hair standing there. And now she was waving us back.

"She wants us inside, where we can't be seen," Georg murmured. We drew back into the room, standing where we still could see the girl. I wondered then—and we had discussed it several times these last hours—if the interior of our tower were under observation by some distant guard. We felt that probably it was, visibly and audibly; and we had been very careful of what we said aloud.

But now, if we were watched, we could not help it; we would have to take the chance. The figure of the girl showed plainly down there through the other casement. And again, with slow-moving white arms she began to semaphore. A queer application of the Secondary Code, which always is used officially with coral-light beams over considerable distances. But it sufficed in this emergency. Slowly she spelled out the letters, words, phrases.
