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.

When he returned the next day he was heartily ashamed of his impatience. To try to catch the Nixy’s notes after half a dozen lessons was, of course, an absurdity.

The master told him simply to banish such folly from his brain, to apply himself diligently to his scales, and not to bother himself about the Nixy.

That seemed to be sound advice and Nils accepted it with contrition. He determined never to repeat his silly experiment. But when the next midsummer night came, a wild yearning possessed him, and he stole out noiselessly into the forest, and sat down on a stone by the river, listening intently.

For a long while he heard nothing but the monotonous boom of the water plunging into the deep. But, strangely enough, there was a vague, hushed rhythm in this thundering roar; and after a while he seemed to hear a faint strain, ravishingly sweet, which vibrated on the air for an instant and vanished.

It seemed to steal upon his ear unawares, and the moment he listened, with a determination to catch it, it was gone. But sweet it was—inexpressibly sweet.

Let the master talk as much as he liked, catch it he would and catch it he must. But he must acquire greater skill before he would be able to render something so delicate and elusive.

Accordingly Nils applied himself with all his might and main to his music, in the intervals between his work.
