After a time Prince Ivan came to where Vertodub was, and found that there were only three trees remaining there. So he took the comb and flung it on the open plain. Immediately from somewhere or other there came a sound of trees, and forth from the ground arose dense oak forests, each stem more huge than the others! Vertodub was delighted, thanked the prince, and set to work uprooting the ancient oaks. By and by Prince Ivan reached the old women, and gave each of them an apple. They ate them, and straightway became young again. So they gave him a handkerchief; you only had to wave it, and behind you lay a whole lake! At last Prince Ivan arrived at home. Out came running his sister to meet him, and caressed him fondly. “Sit thee down, my brother!” she said. “Play a tune on the lute while I go and get dinner ready.” The prince sat down and strummed away on the lute (_gusli_). Then there crept a mouse out of a hole, and said to him in a human voice: “Save yourself, Prince. Run away quick! your sister has gone to sharpen her teeth.” Prince Ivan fled from the room, jumped upon his horse, and galloped away back. Meantime the mouse kept running over the strings of the lute. They twanged, and the sister never guessed that her brother was off. When she had sharpened her teeth she burst into the room. Lo and behold! not a soul was there; nothing but the mouse bolting into his hole. The witch waxed wroth, ground her teeth like anything, and set off in pursuit. Prince Ivan heard a loud noise and looked back. There was his sister chasing him. So he waved his handkerchief, and a deep lake lay behind him. While the witch was swimming across the water, Prince Ivan got a long way ahead. But on she came faster than ever; and now she was close at hand! Vertodub guessed that the prince was trying to escape from his sister. So he began tearing up oaks and strewing them across the road. A regular mountain did he pile up! there was no passing by for the witch! So she set to work to clear the way. She gnawed, and gnawed, and at length contrived by hard work to bore her way through; but by this time Prince Ivan was far ahead. On she dashed in pursuit, chased and chased. Just a little more, and it would be impossible for him to escape! But Vertogor spied the witch, laid hold of the very highest of all the mountains, pitched it down all of a heap on the road, and flung another mountain right on top of it. While the witch was climbing and clambering, Prince Ivan rode and rode, and found himself a long way ahead. At last the witch got across the mountain, and once more set off in pursuit of her brother. By and by she caught sight of him and exclaimed: “You sha’n’t get away from me this time!” And now she is close, now she is just going to catch him! At that very moment Prince Ivan dashed up to the abode of the Sun’s Sister and cried. “Sun, Sun! open the window!” The Sun’s Sister opened the window, and the prince bounded through it, horse and all.
