Koryphu went north with the dawn, and Kalamita was hastening to meet him. Satisfied, he left her in slumbrous ignorance of his presence and visited Naia, telling her of the progress he was making, and how Robur was stoking the furnaces of Himyra toward the creation of yet another marvel, in the eyes of the population, until they flared red above the red walls of the city in the night. In the morning he sent Robur a message announcing his departure, said farewell to Mutlos and was driven to the quays and Jadgor's galley. Going aboard he gave the order for sailing. The sea-doors were opened. He passed through them, and turned the prow of the craft at his disposal swiftly into the south. CHAPTER VII PTAR, PRIEST OF BEL Koryphu of Cathur, under the banner of Tamarizia--with seven red and white stripes and a blue field with seven stars--a thing designed by Croft himself after the republic was established, fared north in a gnuppa drawn conveyance with his escort of Cathurian guards. Kalamita and Zollaria came down from the north in a similar fashion, but with a vastly heavier escort--strong enough as Croft had suggested to Robur to avoid any chance of surprise. Croft sailed south, but watched their progress each night, when he let his consciousness steal forth. The airplanes sailed north and found themselves a landing place as best they might, to which, after each day spent above the mountains north of Cathur's border, they returned. Three days brought Jason to Himyra. Jadgor's galley was swift, indeed. Each day he spent in the shops sometimes with Robur, sometimes without him, when matters of state interfered, drafting designs with ruler and calipers and stylus, supervising the makings of patterns, holding consultations with his captains over the production of each part he desired, calling for speed and more speed. It was the thing that obsessed him now that Koryphu was going north and Kalamita was coming south--speed in the production of the only thing that seemed to his straining mind fitted to meet his desperate need. And a part of each night he spent in the laboratory he had fitted up in Robur's own part of the palace, experimenting in the blending of reagents, the making of the liquid fire. In Zitra, in Cathur and in Aphur, Tamarizia roared, and by degrees the other states of the nation had the word of the last Zollarian outrage and added their voices to the chorus of resentment and demand for some retaliatory move. Croft had their sympathy and support in his plans of rescue, unequivocally expressed.
