No other details were given in the Great Book and so Glinda did not know that since Coo-ee-oh had forgotten her magic none of the Skeezers knew how to raise the island to the surface again. So Glinda was not worried about Ozma and Dorothy until one morning, while she sat with her maids, there came a sudden clang of the great alarm bell. This was so unusual that every maid gave a start and even the Sorceress for a moment could not think what the alarm meant.

Then she remembered the ring she had given Dorothy when she left the palace to start on her venture. In giving the ring Glinda had warned the little girl not to use its magic powers unless she and Ozma were in real danger, but then she was to turn it on her finger once to the right and once to the left and Glinda's alarm bell would ring.

So the Sorceress now knew that danger threatened her beloved Ruler and Princess Dorothy, and she hurried to her magic room to seek information as to what sort of danger it was. The answer to her question was not very satisfactory, for it was only: "Ozma and Dorothy are prisoners in the great Dome of the Isle of the Skeezers, and the Dome is under the water of the lake."
