His words, and his manner of going, frightened the Princess. She again began to look about her for some way of escape. Suddenly she saw upon the floor the grey cap that the dwarf had carried in his hand. He must have dropped it when he fell, and he had been too angry to notice that he was leaving it behind. She picked it up and stood turning it thoughtfully in her hands. Then, without considering why she did so, she placed it upon her head. She was standing directly in front of a mirror at the time. To her amazement, the moment she had the cap on her head every reflection of her vanished from every mirror in the room. The Princess could hardly believe her eyes. She might have been thin air for any impression she made upon the glass. She took the cap from her head, and immediately her reflections appeared again in the mirrors. She replaced it, and they vanished from sight. Then the Princess knew that she held the Cap of Invisibility—the cap that causes anyone who wears it to become invisible. As she stood there with the cap still upon her head, the mirror door was burst open and the dwarf rushed into the room. His dress was disordered and his eyes glared wildly. He looked hastily about him, but he could see neither the cap nor the Princess. At once he knew that she had found the cap and had put it on. “Ah, ha!” he cried to the invisible Princess. “So you have found it! You have put it on, and hope so to escape me. But I know you are still here, even though I cannot see you. I will find you, never fear.” Spreading his arms wide, he rushed about the room, hoping to touch the Princess and seize her, but as he could not see her she was easily able to escape him. Now and then he stopped and listened, hoping the Princess would make some sound that would tell him where she was, but at these times Beautiful too stood still. She did not move, she scarcely breathed, lest he should hear her. Suddenly the Princess saw something that gave her a hope of escape. The dwarf had neglected to fasten the swinging mirror behind him when he entered. She flew to it and pushed it open. Beyond lay a long corridor. Down this the Princess fled, not knowing where it would lead her. But the dwarf saw the mirror move, and guessed she had passed out through it. With a cry of rage he sprang after her. At the end of the corridor was a barred door. Beautiful had scarcely time to unfasten this door and run through before the dwarf reached it. But once outside the door she found herself in a wide and open garden. Here she could pause and take breath. The dwarf had no means of knowing in which direction she had gone. He could not hear her footsteps upon the soft grass, and the rustling of the wind among the leaves prevented his hearing the sound of her dress as she moved.
