Chapter Twenty. A Puzzling Problem

Glinda the Good, having decided to try her sorcery upon the abandoned submarine, so that it would obey her commands, asked all of her party, including the Skeezers, to withdraw from the shore of the take to the line of palm trees. She kept with her only the little Wizard of Oz, who was her pupil and knew how to assist her in her magic rites. When they two were alone beside the stranded boat, Glinda said to the Wizard:

"I shall first try my magic recipe No. 1163, which is intended to make inanimate objects move at my command. Have you a skeropythrope with you?"

"Yes, I always carry one in my bag," replied the Wizard. He opened his black bag of magic tools and took out a brightly polished skeropythrope, which he handed to the Sorceress. Glinda had also brought a small wicker bag, containing various requirements of sorcery, and from this she took a parcel of powder and a vial of liquid. She poured the liquid into the skeropythrope and added the powder. At once the skeropythrope began to sputter and emit sparks of a violet color, which spread in all directions. The Sorceress instantly stepped into the middle of the boat and held the instrument so that the sparks fell all around her and covered every bit of the blackened steel boat. At the same time Glinda crooned a weird incantation in the language of sorcery, her voice sounding low and musical.

After a little the violet sparks ceased, and those that had fallen upon the boat had disappeared and left no mark upon its surface. The ceremony was ended and Glinda returned the skeropythrope to the Wizard, who put it away in his black bag.

"That ought to do the business all right," he said confidently

"Let us make a trial and see," she replied.

So they both entered the boat and seated themselves.

Speaking in a tone of command the Sorceress said to the boat: "Carry us across the lake, to the farther shore."

At once the boat backed off the sandy beach, turned its prow and moved swiftly over the water.

"Very good -- very good indeed!" cried the Wizard, when the boat slowed up at the shore opposite from that whence they had departed. "Even Coo-ee-oh, with all her witchcraft, could do no better."

The Sorceress now said to the boat:

"Close up, submerge and carry us to the basement door of the sunken island -- the door from which you emerged at the command of Queen Coo-ee-oh."

The boat obeyed. As it sank into the water the top sections rose from the sides and joined together over the heads of Glinda and the Wizard, who were thus enclosed in a water-proof chamber. There were four glass windows in this covering, one on each side and one on either end, so that the passengers could see exactly where they were going. Moving under water more slowly than on the surface, the submarine gradually approached the
