"Come in," says she, and she took little Prince Ivan with her to a room in the palace, all broken down and cobwebbed. There was a dulcimer lying in the dust on the floor. "Well, little brother," says the witch baby, "you play on the dulcimer and amuse yourself while I get supper ready. But don't stop playing, or I shall feel lonely." And she ran off and left him. Little Prince Ivan sat down and played tunes on the dulcimer--sad enough tunes. You would not play dance music if you thought you were going to be eaten by a witch. But while he was playing a little gray mouse came out of a crack in the floor. Some people think that this was the wise old groom, who had turned into a little gray mouse to save Ivan from the witch baby. "Ivan, Ivan," says the little gray mouse, "run while you may. Your father and mother were eaten long ago, and well they deserved it. But be quick, or you will be eaten too. Your pretty little sister is putting an edge on her teeth!" Little Prince Ivan thanked the mouse, and ran out from the ruined palace, and climbed up on the back of his big black horse, with its saddle and bridle trimmed with silver. Away he galloped over the wide world. The witch baby stopped her work and listened. She heard the music of the dulcimer, so she made sure he was still there. She went on sharpening her teeth with a file, and growing bigger and bigger every minute. And all the time the music of the dulcimer sounded among the ruins. As soon as her teeth were quite sharp she rushed off to eat little Prince Ivan. She tore aside the walls of the room. There was nobody there--only a little gray mouse running and jumping this way and that on the strings of the dulcimer. When it saw the witch baby the little mouse ran across the floor and into the crack and away, so that she never caught it. How the witch baby gnashed her teeth! Poker and tongs, poker and tongs--what a noise they made! She swelled up, bigger and bigger, till she was a baby as high as the palace. And then she jumped up so that the palace fell to pieces about her. Then off she ran after little Prince Ivan. Little Prince Ivan, on the big black horse, heard a noise behind him. He looked back, and there was the huge witch, towering over the trees. She was dressed like a little baby, and her eyes flashed and her teeth clanged as she shut her mouth. She was running with long strides, faster even than the black horse could gallop--and he was the best horse in all the world. Little Prince Ivan threw down the handkerchief that had been sewn by the two old women who had eaten the apples of youth. It turned into a deep, broad lake, so that the witch baby had to swim--and swimming is slower than running. It took her a long time to get across, and all that time Prince Ivan was galloping on, never stopping for a moment.
