A smile twitched Robur's lip as he caught the unaccustomed meaning. "And at times I find a strange application of meaning in thy words, Jason," he replied. "It is so in the manner of speech you use concerning the games of baseball when the contest waxes warm. 'Tear its hide off! Lay on that pill! Lean on it! Lean on it!'—the word 'charley-horse' which you sometimes employ, and the naming of an arm a 'wing.' None the less thou art a sight to gladden a maiden's eyes, my friend, and even now a maid and a matron await thee beside the bathing pool. So—get thee gone! Thou art beautiful enough."

With another laugh Croft took him at his word, descending to the court where the swimming pool sparkled in the late afternoon sunlight, and advancing in a considerable blaze of material glory to where, on couches beneath a shimmering awning, Gaya and Naia reclined.

"Hai, Jason!" Robur's wife exclaimed, extending a hand as she saw him. "Welcome, thou tamer of the lightning, as my lord has said thou art. Wilt pardon a matron's indolence, or should I greet thee on my feet?"

"Nay." Croft took her hand and bent above it. "I like thee less, wife of Robur, in the formal mood. Retain the charm of thy ease." Then deliberately he turned his eyes and met those of Naia. "Greeting to thee, maid of Aphur," he said.

"And to thee, Mouthpiece of Zitu," she returned with her pansy-purple eyes fixed on the flashing symbol on his breast.

Croft noted the glance, the slight tensing of the lines about her mouth as he sat down. He had meant from the first to note its effect. Indeed, he had worn it to this meeting of a purpose. It was his intent that, in spite of it, and all it stood for, or had stood for at one time in her mind, her surrender should be gained.

"As to the harnessing of Zitu's fire, 'tis no more than a following out of Zitu's law when understood," he turned to Gaya to explain. "The generation of 'elektricity,' as it is called, is no more in this case than the changing of one force into another, a transfer of energy from—-"

"Ah, Ga, I am a woman, unversed in such matters!" Gaya exclaimed with a dancing in her eyes. "I fear I am too old to learn. Naia is of a younger generation, her mind of softer substance; grave thy meaning on its tablet with the stylus of thy tongue. I would see Robur before the evening meal. It were time he had returned."

"Aye," said Croft, smiling and rising to assist her to her feet. "Even now he is within the palace. We spoke before I came forth."

He watched while she hurried importantly away, still smiling inwardly at her palpable subterfuge for leaving Naia and him alone; then turned to where Lakkon's daughter still reclined, and resumed his seat.
