Then Ivan set the copper ball rolling and followed it until he came to a castle all of silver and finer than the first. At the gateway were terrible writhing serpents fastened with silver chains, and near them was a well with a silver bucket. Remembering the previous reward for his impulse of kindliness, Ivan drew water and gave it to the serpents to drink. When they had quenched their thirst they lay down in quiet, and Ivan was able to enter the castle unmolested. At the doorway, and just over the threshold, he was met by a Tsaritza, who was clothed in cloth of silver and whose hair was of fine white silver, which yet did not take away from the beauty of her youthfulness. At first she did not see Ivan, and she spoke to herself. "It will soon be three years," she said, "since Whirlwind the Whistler first imprisoned me in this silver castle, and during that time I have not seen or spoken with a dweller in Holy Russia. But by my lost Kingdom I see a Russian now and a goodly one." Then she bent her beautiful eyes upon Ivan and said in a voice like a silver bell, "Who are you, good youth?" "I am Ivan, youngest son of the Great White Tsar," was the simple answer. "How did you come here?" asked the Silver Tsaritza, "with your own will or against your will?" "With my own will," said Ivan. "I am in search of my mother. For, while she walked in the green palace garden, Whirlwind the Whistler came with a shriek and bore her away to an unknown land. Can you tell me where I may find her?" "No, I cannot," was the reply, "but not far away from here lives my eldest sister the Golden Tsaritza, Elena the Lovely--perhaps she will be able to tell you where you may find Golden Tress. But I pray you, good youth, when you have killed Whirlwind the Whistler, do not forget me, poor unfortunate, but rescue me from this place and take me out into the free white world. Whirlwind the Whistler holds me here as a captive, and comes once in two months to torment me with his hideous voice." Then she gave the good youth a silver ball and a silver ring as a token and said to him, "Within this little circle lies the whole of the Kingdom of Silver." Once more Ivan set the ball rolling, and wherever it went, there he followed it, and he came at last across many leagues of open country to a castle of gold. At the gateway sat terrible wriggling serpents fastened with golden chains, crowds of them writhing in a mass upon the earth; and not far away was a well at the mouth of which was a golden bucket fastened with a golden chain. Again Ivan watched the writhing serpents for a moment and then drew water in the golden bucket and gave to them to drink. When they had quenched their thirst they lay down in quiet, and Ivan was able to enter the castle unmolested. At the doorway, and just over the threshold, he was met by a Tsaritza, who was clothed in cloth of gold and whose hair was of fine red gold glowing with the fire of youthfulness. At once she saw Ivan and said to him:
