I will come every evening to see if thou hast obeyed my order." The boy placed himself by the margin of the well, and often saw a golden fish or a golden snake show itself therein, and took care that nothing fell in. As he was thus sitting, his finger hurt him so violently that he involuntarily put it in the water. He drew it quickly out again, but saw that it was quite gilded, and whatsoever pains he took to wash the gold off again, all was to no purpose. In the evening Iron John came back, looked at the boy, and said, "What has happened to the well?" "Nothing, nothing," he answered, and held his finger behind his back, that the man might not see it. But he said, "Thou hast dipped thy finger into the water, this time it may pass, but take care thou dost not again let anything go in." By daybreak the boy was already sitting by the well and watching it. His finger hurt him again and he passed it over his head, and then unhappily a hair fell down into the well. He took it quickly out, but it was already quite gilded. Iron John came, and already knew what had happened. "Thou hast let a hair fall into the well," said he. "I will allow thee to watch by it once more, but if this happens for the third time then the well is polluted, and thou canst no longer remain with me."
On the third day, the boy sat by the well, and did not stir his finger, however much it hurt him. But the time was long to him, and he looked at the reflection of his face on the surface of the water. And as he still bent down more and more while he was doing so, and trying to look straight into the eyes, his long hair fell down from his shoulders into the water. He raised himself up quickly, but the whole of the hair of his head was already golden and shone like the sun. You may imagine how terrified the poor boy was! He took his pocket-handkerchief and tied it round his head, in order that the man might not see it. When he came he already knew everything, and said, "Take the handkerchief off." Then the golden hair streamed forth, and let the boy excuse himself as he might, it was of no use.
