It was easy enough for a rich man's son to be good, Nils thought.
It was small credit to him if he was not envious, having never known want and never gone to bed on birch-bark porridge. But for a poor boy not to covet all the nice things which would make life so pleasant, if he had them, seemed next to impossible.
Still Nils kept on making good resolutions and breaking them, and then piecing them together again and breaking them anew.
If it had not been for his desire to see the Hulder and the Nixy, and making them promise the fulfilment of the three wishes, he would have given up the struggle, and resigned himself to being a bad boy because he was born so. But those teasing glimpses of the Hulder's scarlet bodice and golden hair, and the vague snatches of wondrous melody that rose from the cataract in the silent summer nights, filled his soul with an intense desire to see the whole Hulder, with her radiant smile and melancholy eyes, and to hear the whole melody plainly enough to be written down on paper and learned by heart.
It was with this longing to repeat the few haunting notes that hummed in his brain that Nils went to the schoolmaster one day and asked him for the loan of his fiddle. But the schoolmaster, hearing that Nils could not play, thought his request a foolish one and refused.
Nevertheless, that visit became an important event, and a turning-point in the boy's life. For he was moved to confide in the schoolmaster, who was a kindly old man, and fond of clever boys; and he became interested in Nils. Though he regarded Nils's desire to record the Nixy's strains as absurd, he offered to teach him to play. There was good stuff in the lad, he thought, and when he had out-grown his fantastic nonsense, he might, very likely, make a good fiddler.
Thus it came to pass that the charcoal-burner's son learned to play the violin. He had not had half a dozen lessons before he set about imitating the Nixy's notes which he had heard in the waterfall.
"It was this way," he said to the schoolmaster, pressing his ear against the violin, while he ran the bow lightly over the strings; "or rather it was this way," making another ineffectual effort. "No, no, that wasn't it, either. It's no use, schoolmaster: I shall never be able to do it!" he cried, flinging the violin on the table and rushing out of the door.
