If, therefore, Dalis could mask his own thoughts from the brains of men, he could also mask the thoughts of the people of his Gens, merely by willing it! So Sarka and his father and Jaska could not know whether the Gens of Dalis had gone over in a body with him, in a truce with the people of the Moon, or whether they were dual prisoners--of Dalis and of the Moon-men! More than ever was it necessary for someone to somehow reach the Moon and make a thorough investigation, discover just what Dalis was doing, what mischief he was hatching. The secret exit dome seemed to be the answer. "You can manage without me, father?" asked Sarka. * * * * * The elder Sarka nodded. "Of the other Spokesmen of Earth," went on Sarka, "I trust Gerd the most. Might I suggest that you bring him here, trust him in all details, and let him take my place wherever possible? Or, better still, keep Jaska here with you! I ... I may not be able to return! I'll try to find a way, but--we can always communicate telepathically. Jaska...." "Jaska," said that young lady grimly, "goes with Sarka wherever Sarka goes!" "But it may mean death! We can only guess at the cunning of the Moon dwellers! They may have been in secret communication with Dalis for centuries! Dalis, who somehow discovered our secret finger code, may also know of the secret exit dome, and the principle upon which it operates! If he does, he may know how to combat it! Perhaps that explains his laughter! Perhaps he heard and understood every word we spoke, hears and understands every word we speak now! Who knows? He may wait until I have passed through the secret exit dome, and then make it impossible for me to be reincarnated on the Moon--or elsewhere!" "No matter," said Jaska softly, "wherever Sarka goes, there goes Jaska! It is useless to attempt to dissuade me, and it is time you learned that!" In spite of himself Sarka smiled, and his father met his smile with a quizzical one of his own. Both men had the same thought. "The eternal woman!" said Sarka the Elder. "No man has ever understood her--no man ever will! And all men are ruled by her!" Sarka shrugged, and Jaska spoke again. "Don't you think it is time we tried this new experiment?" * * * * * Sarka nodded, and his face was suddenly alight with the excitement which burned within him. "First," he said, "we need accoutrements of the Gens of Dalis for two people!" Jaska smiled. "Forseeing that we might have need of such equipment, I had several complete outfits sent here when I took charge of the Gens of Dalis as its Spokesman!"
