But there is only one wish in t ring so think carefully before you wish The astonished farmer took the ring given to him by sant woman, and went home. In evening Came to a big city There he went to a merchant and ved him the magic ring. When the merchant heard the astonishing story, he thought of a plant Hea vited the farmer to stay in his house for the night. At night he came up to the sleeping pea carefully took the ring off the man's finger, and put on another ving, which looked exactly like the one he had taken off In the morning when the farmer had gone the merchant ran into his shop shut the door, and said while turning the ring on his finger Lush to have a hundred thousand nieces of gold. And down they came, on his head houlders, and arms, e a rain of gold The frotaped merchant tried to get out of the shop, but in) van a few minutes he was dead When the farmer returned home, he showed the ring to his wife -Take a look at this rings he said its a magic ringt male in Happy The astonished woman could hardly say a word-Let's try Maybe the ring will bring us more land she said at last.

So they worked as hard as they could and got enough money to buy the land they wished to have. What happy people we are! said the farmer: I don't understand you answered his wife angrily. There's nothing in the world that we can't have, and still we spend days and nights working as hand as before because you don't want to use your magic ring Thirty, then forty years had gone by.
