He was very angry—angry with Ozma and angry with himself—because, now that he took time to think, he remembered that he knew very well the art of making people invisible, and visible again, and if he had only thought of it in time he could have used his magic knowledge to make the girls visible and so have captured them easily.

In the center of this lake appeared a lovely island, not of great extent but almost entirely covered by a huge round building with glass walls and a high glass dome which glittered brilliantly in the
