Flushed with her dancing in the sunlight, and with the languor of August in her blood, Oona listened eagerly to the cool sound of the running of Mairg Water.
The next moment she was free of her scanty raiment, and was by the streamside. As she stood among a cluster of yellow irises, the sunlight lay upon the gold of her hair and the glowing ivory-white of her body, and then seemed to spill in yellow fire among the tall blooms about her feet. A faint green glimmer from the emerald iris-sheaths dusked the small white thighs.
A leap like a fawn, and she was in the water. A hundred miniature rainbows gleamed in the dazzle of spray as she splashed to and fro, after she had come to the surface some yards downstream. What joy it was to feel the cool brown water laving her body: to dive and swim like an otter: to float slowly with the current under overhanging foliage, and see the young sedge-warblers in the reeds or among the water-willows, or to look up at the curving boughs of a birch or rowan, deep green against the deep blue! Then the wonder and beauty to rest with outspread arms, and breast against the flow: to stare down into the mirroring depth, and see the flickering feathers of the quicken and the red rowan-berries marvellously real and near, with lovely shadow-birds flitting to and fro among the shadow-branches, and, strangest of all, another white Oona drifting like a phantom through that greenshine underworld!
When she swung round suddenly, and held herself back against the downflow, as an otter half-alarmed will do, it was not because she was drifting too near the "race" just above the cataract. A strange sound came from the Linn, or beyond it. The noise of the water was in her ears, and she could not hear distinctly: but surely that noise was the cry of one in sorrow, and, at any rate, human.
With a swift movement she slid to the bank, caught at a tuft of flowering sedge, and then stood, dripping and all agleam in the sunlight, while with inclined head she listened intently.
Now she could hear more distinctly: certainly some one was by or near the Linn. The noise of the churned waters rose and fell in a long, wavering, unequal sigh; and in one of the downward hushes her keen ears caught tones and even words she fancied she recognised.
She hesitated for a moment as to whether to run back for the handful of clothes she had left upstream, but then bethought her that it was only Nial and no stranger who might throw stones at her as a kelpie—as some boys from the Strath, who at Beltane had been burning small fires and cooking wild-birds' eggs, had done many weeks agone at Nial.[14]
How often, in her wanderings with Nial, she had bathed, to his wonder and awe at her white beauty, her daring, her skill! As for him, though he loved the running water almost with a passion, nothing would induce him to enter it, except when alone and in the dim light. As a boy he had been as much at home in it as any creature of the river. But once, after he had come to know Oona, and to find in her the one person in the world whose soul did not loom too infinitely remote above his drear loneliness of spirit, he had leaped one dead-calm noon into the water; and there and then, for the first time, realised, in the phantom which swam with him or beneath him, the misshapen ugliness of his body, the savagery of his distorted head and features. From that day he had never entered the stream, save at late dusk or on moonless nights.
So with swift steps, which left small pads of damp upon the rock-ledges, Oona ran toward the great boulder which overhung the cataract.
As she passed the place where, a few hours ago, she had left her foster-father and the woman Anabal, she glanced here and there for any trace of either she might not have seen before. The next moment she caught sight of Nial.
