Gaya smiled. Like most of the Tamarizian women, Croft had seen she seemed devoid of any particular fear. She took Robur's hand and stepped into the car. Robur followed with scant dignity in his eagerness to put this new mode of travel to the test. Then Croft engaged his clutch and the car moved off, rolling without apparent means of propulsion in circles about the great red court while the guards and Jadgor watched. For some five minutes Croft kept up the circling before he brought the machine to a stand before the king, and once more rising, bowed. "Your words were true, O Jasor," spoke Jadgor then. "In this I see great service to the state. Hail Hupor!" He caught a sword from the nearest soldier, and advancing, struck Croft lightly upon the breast with the flat of the blade. "More of this tonight," he said, stepping back. "In the meantime arrange to build as many of these moturs as you may--also for those which shall propel the boats." Turning, he withdrew with his guard, disappearing into the palace. Gaya smiled at her husband and Croft. "I, too, shall withdraw now," she began. "I can see you are eager to be alone with this new toy. My thanks, Lord Jasor, for the ride. All my life long I shall remember myself the first of Tamarizian women to mount your wonderful car." Robur helped her to get out, then sprang back to Croft's side. His face was alight. "Now--go! Let us ride!" he exclaimed. "Let us leave the city along the highway to the south and test the motur for speed." Nothing loth, Croft once more advanced gas and spark and let in the clutch. Outside the palace entrance he turned south along the Na. Robur, beside him, seemed strangely like a boy. "Approach the gate slowly," he chuckled as they rode. "Let me see for myself what effect we have on the guards." His wish was granted in a surprisingly short time. As they neared the gate, not yet open to morning traffic, a guardsman appeared. Plainly he was watching, yet he made no move. He seemed practically paralyzed at the sight which met his eyes. In the end, however, he suddenly lifted his spear as though expecting to meet a charge with its point. His face was rigidly set. He appeared one determined to die in the path of duty if die he must. "Open, fellow!" Robur shouted with a grin. His voice wrought a change in the man. He caught a deep breath, dropped his spear and flung himself toward the levers which worked the gate. "My lord," he said, as Croft drove past where he now stood at attention with the gate swung wide. "My lord!" Robur flung him a bit of silver and a laugh. Then they were out of the tunnel through the wall and rushing up the well-built road. "That fellow thought us Zitemque himself, to judge by his expression," he chuckled. "Jasor, my friend--go faster--let--" "Let her out!" Croft could not resist the expression of earth. "Aye," said Robur, staring. "Let--her--out. Where got you that form of speech, my friend?"
