The Complete Grimm's Fairy Tales (Pantheon Books) - Jacob Grimm [206]
The father then borrowed an axe of the neighbor, and next morning at break of day they went out into the forest together. The son helped his father and was quite merry and brisk about it. But when the sun was right over their heads, the father said: “We will rest, and have our dinner, and then we shall work twice as well.” The son took his bread in his hands, and said: “Just you rest, father, I am not tired; I will walk up and down a little in the forest, and look for birds’ nests.” “Oh, you fool,” said the father, “why should you want to run about there? Afterwards you will be tired, and no longer able to raise your arm; stay here, and sit down beside me.”
The son, however, went into the forest, ate his bread, was very merry and peered in among the green branches to see if he could discover a bird’s nest anywhere. So he walked to and fro until at last he came to a great dangerous-looking oak, which certainly was already many hundred years old, and which five men could not have spanned. He stood still and looked at it, and thought: “Many a bird must have built its nest in that.” Then all at once it seemed to him that he heard a voice. He listened and became aware that someone was crying in a very smothered voice: “Let me out, let me out!” He looked around, but could discover nothing; then he fancied that the voice came out of the ground. So he cried: “Where are you?” The voice answered: “I am down here amongst the roots of the oak-tree. Let me out! Let me out!” The schoolboy began to loosen the earth under the tree, and search among the roots, until at last he found a glass bottle in a little hollow. He lifted it up and held it against the light, and then saw a creature shaped like a frog, springing up and down in it. “Let me out! Let me out!” it cried anew, and the boy, thinking no evil, drew the cork out of the bottle. Immediately a spirit ascended from it, and began to grow, and grew so fast that in a very few moments he stood before the boy, a terrible fellow as big as half the tree. “Do you know,” he cried in an awful voice, “what your reward is for having let me out?” “No,” replied the boy fearlessly, “how should I know that?” “Then I will tell you,” cried the spirit; “I must strangle you for it.” “You should have told me that sooner,” said the boy, “for I should then have left you shut up, but my head shall stand fast for all you can do; more persons than one must be consulted about that.” “More persons here, more persons there,” said the spirit. “You shall have the reward you have earned. Do you think that I was shut up there for such a long time as a favor? No, it was a punishment for me. I am the mighty Mercurius. Whoso releases me, him must I strangle.” “Slowly,” answered the boy, “not so fast. I must first know that you really were shut up in that little bottle, and that you are the right spirit. If, indeed, you can get in again, I will believe, and then you may do as you will with me.” The spirit said haughtily: “That is a very trifling feat,” drew himself together, and made himself as small and slender as he had been at first, so that he crept through the same opening, and right through the neck of the bottle in again. Scarcely was he within than the boy thrust the cork he had drawn back into the bottle, and
