"I will fight the Skeezers," exclaimed the Flathead chief, "and if a dozen Ozmas of Oz forbade me I would fight just the same." "Not if I can prevent it!" asserted Ozma. "You can't prevent it. But since you threaten me, I'll have you confined in the bronze prison until the war is over," said the Su-dic. He whistled and four stout Flatheads, armed with axes and spears, entered the room and saluted him. Turning to the men he said: "Take these two girls, bind them with wire ropes and cast them into the bronze prison." The four men bowed low and one of them asked: "Where are the two girls, most noble Su-dic?" The Su-dic turned to where Ozma and Dorothy had stood but they had vanished! Chapter Seven The Magic Isle Ozma, seeing it was useless to argue with the Supreme Dictator of the Flatheads, had been considering how best to escape from his power. She realized that his sorcery might be difficult to overcome, and when he threatened to cast Dorothy and her into a bronze prison she slipped her hand into her bosom and grasped her silver wand. With the other hand she grasped the hand of Dorothy, but these motions were so natural that the Su-dic did not notice them. Then when he turned to meet his four soldiers, Ozma instantly rendered both herself and Dorothy invisible and swiftly led her companion around the group of Flatheads and out of the room. As they reached the entry and descended the stone steps, Ozma whispered: "Let us run, dear! We are invisible, so no one will see us." Dorothy understood and she was a good runner. Ozma had marked the place where the grand stairway that led to the plain was located, so they made directly for it. Some people were in the paths but these they dodged around. One or two Flatheads heard the pattering of footsteps of the girls on the stone pavement and stopped with bewildered looks to gaze around them, but no one interfered with the invisible fugitives. The Su-dic had lost no time in starting the chase. He and his men ran so fast that they might have overtaken the girls before they reached the stairway had not the Golden Pig suddenly run across their path. The Su-dic tripped over the pig and fell flat, and his four men tripped over him and tumbled in a heap. Before they could scramble up and reach the mouth of the passage it was too late to stop the two girls. There was a guard on each side of the stairway, but of course they did not see Ozma and Dorothy as they sped past and descended the steps. Then they had to go up five steps and down another ten, and so on, in the same manner in which they had climbed to the top of the mountain. Ozma lighted their way with her wand and they kept on without relaxing their speed until they reached the bottom. Then they ran to the right and turned the corner of the invisible wall just as the Su-dic and his followers rushed out of the arched entrance and looked around in an attempt to discover the fugitives.
