“Oh , I' m not at all afraid . Pray , what will he look like?”
“Why, he'll look the very image of a parish-clerk . ”
“Ha！” said the farmer, “ that is ugly! You must know, I can' t bear the sight of a clerk . But it doesn't matter now, for I know that he's a demon, so I shall easily stand it. Now I have courage, but he must not come too near me . ”
“Now I will ask my conjuror,” said Little Claus; and he trod on the sack and held his ear down .
“What does he say?”
“He says you may go and open the chest that stands in the corner, and you will see the demon crouching in it; but you must hold the lid so that he doesn't slip out . ”
“Will you help me to hold him?” asked the farmer. And  had hidden the real clerk , who sat in there and was very much afraid . The farmer opened the lid a little way and peeped in underneath it .
“Ugh ! ” he cried , and sprang backward . “Yes , now I've seen him, and he looked exactly like our clerk. Oh, that was dreadful ! ”
Upon this they must drink . So they sat and drank until late into the night .
“You must sell me that conjuror,” said the farmer. “Ask as much as you like for him. I'll give you a whole bushel of money directly . ”
“No, that I can't do,” said Little Claus: “only think how much use I can make of this conjuror.”
“Oh, I should so much like to have him!” cried the farmer; and he went on begging.
“Well , ” said Little Claus , at last , “as you have been so kind as to give me shelter for the night , I will let it be so . You shall have the conjuror for a bushel of money; but I must have the bushel heaped up . ”
“That you shall have,” replied the farmer. “But you must take the chest yonder away with you . I will not keep it in my house an hour. One cannot know ---- perhaps he may be there still . ”
Little Claus gave the farmer his sack with the dry hide in it, and got in exchange a whole bushel of money, and that heaped up . The farmer also gave him a big truck , on which to carry off his money and chest .
