They ran on and on, and they smelt out the scent everywhere and followed it; paid great attention to what people told them; carefully made friends with all the other dogs and cats they met; asked about the Princess, and found out at last that they were not far from the kingdom of Thrice-ten, whither she had told the twelve youths to carry her. They ran into the kingdom, went to the palace, and made friends with all the dogs and cats there, asked them all about the Princess's ways, and turned the conversation to the subject of the enchanted ring; but no one could give them certain information about it. But one day it happened that Vaska went a-hunting in the royal cellars. There he waylaid a big fat mouse, threw himself upon it, dug his cruel claws into it, and was going to begin with its head, when the big mouse spoke to him: "Dear little Vaska, don't hurt me, don't kill me. Perhaps I may be of service to you. I'll do all I can for you. But if you kill me, the Mouse-Tsar, all my mousey tsardom will fall to pieces."--"Very well," said Vaska; "I'll spare you; but this is the service you must do me. In this palace dwells the Princess, the wicked wife of our master; she has stolen from him his wonder-working ring; till you have got me that ring, I will not let you out of my claws under any pretence whatever."--Agreed," said the Mouse-Tsar, "I'll try"; and he piped and whistled all his people together. A countless multitude of mice assembled, both small and great, and they sat all round the cat Vaska, and waited to hear what the Mouse-Tsar would say to them from beneath Vaska's claws. And the Mouse-Tsar said to them: "Whichever of you shall get the wonder-working ring from the Princess, he will save me from a cruel death, and I will raise him to the highest place about my person." Then a little mouse rose up and said: "I have often been in the Princess's bed-chamber, and I've noticed that the Princess's eye rests more often on a certain little ring than on anything else. In the daytime she wears it on her little finger, but at night she stuffs it into her mouth behind her cheeks. If you wait a bit, I'll get you that ring." And the little mouse ran into the Princess's bed-chamber and waited till night, and as soon as ever the Princess was asleep, it wriggled into her bed, picked the down out of her swan-feathered bolster, and strewed it all about under her nose. The fine down went up the Princess's nose and into her mouth, she sprang up and began to sneeze and cough, and spat out the enchanted ring on to the counterpane. The little mouse immediately snatched it up, and ran off with it to save the life of the Mouse-Tsar.
