Asathor's Vengeance by Hjalmar Hjorth Boysen

Far up in the glen, about a mile from Kvaerk, ran a little brook; that is, it was little in summer and winter, but in the spring, while the snow was melting up in the mountains, it overflowed the nearest land and turned the whole glen into a broad and shallow river. It was easy to cross, however; a light foot might jump from stone to stone, and be over in a minute. Not the hind herself could be lighter on her foot than Aasa was; and even in the spring-flood it was her wont to cross and recross the brook, and to sit dreaming on a large stone against which the water broke incessantly, rushing in white torrents over its edges.

Here she sat one fair summer day -- the day after Vigfusson's departure. It was noon, and the sun stood high over the forest. The water murmured and murmured, babbled and whispered, until at length there came a sudden unceasing tone into its murmur, then another, and it sounded like a faint whispering song of small airy beings. And as she tried to listen, to fix the air in her mind, it all ceased again, and she heard but the monotonous murmuring of the brook. Everything seemed so empty and worthless, as if that faint melody had been the world of the moment. But there it was again; it sung and sung, and the birch overhead took up the melody and rustled it with its leaves, and the grasshopper over in the grass caught it and whirred it with her wings. The water, the trees, the air, were full of it. What a strange melody!
