On the night referred to in particular, the sisters felt more especially the decay of the confidence which used to exist betwixt them. The proposed voyage to Kirkwall, and that at the time of the fair, when persons of every degree in these islands repair thither, either for business or amusement, was likely to be an important incident in lives usually so simple and uniform as theirs; and, a few months ago, Minna and Brenda would have been awake half the night, anticipating, in their talk with each other, all that was likely to happen on so momentous an occasion. But now the subject was just mentioned, and suffered to drop, as if the topic was likely to produce a difference betwixt them, or to call forth a more open display of their several opinions than either was willing to make to the other.

Yet such was their natural openness and gentleness of disposition, that each sister imputed to herself the fault that there was aught like estrangement existing between them; and when, having finished their devotions, and betaken themselves to their common couch, they folded each other in their arms, and exchanged a sisterly kiss, and a sisterly good-night, they seemed mutually to ask pardon, and to exchange forgiveness, although neither said a word of offence, either offered or received; and both were soon plunged in that light and yet profound repose, which is only enjoyed when sleep sinks down on the eyes of youth and innocence.

On the night to which the story relates, both sisters were visited by dreams, which, though varied by the moods and habits of the sleepers, bore yet a strange general resemblance to each other.

Minna dreamed that she was in one of the most lonely recesses of the beach, called Swartaster, where the incessant operation of the waves, indenting a calcarious rock, has formed a deep halier, which, in the language of the island, means a subterranean cavern, into which the tide ebbs and flows. Many of these run to an extraordinary and unascertained depth under ground, and are the secure retreat of cormorants and seals, which it is neither easy nor safe to pursue to their extreme recesses. Amongst these, this halier of Swartaster was accounted peculiarly inaccessible, and shunned both by fowlers and by seamen, on account of sharp angles and turnings in the cave itself, as well as the sunken rocks which rendered it very dangerous for skiffs or boats to advance far into it, especially if there was the usual swell of an island tide. From the dark-browed mouth of this cavern, it seemed to Minna, in her dream, that she beheld a mermaid issue, not in the classical dress of a Nereid, as in Claud Halcro’s mask of the preceding evening, but with comb and glass in hand, according to popular belief, and lashing the waves with that long scaly train, which, in the traditions of the country, forms so frightful a contrast with the fair face, long tresses, and displayed bosom, of a human and earthly female, of surpassing beauty. She seemed to beckon to Minna, while her wild notes rang sadly in her ear, and denounced, in prophetic sounds, calamity and woe.

The vision of Brenda was of a different description, yet equally melancholy. She sat, as she thought, in her favourite bower, surrounded by her father and a party of his most beloved friends, amongst whom Mordaunt Mertoun was not forgotten. She was required to sing; and she strove to entertain them with a lively ditty, in which she was accounted eminently successful, and which she sung with such simple, yet natural humour, as seldom failed to produce shouts of laughter and applause, while all who could, or who could not sing, were irresistibly compelled to lend their voices to the chorus. But, on this occasion, it seemed as if her own voice refused all its usual duty, and as if, while she felt herself unable to express the words of the well-known air, it assumed, in her own despite, the deep tones and wild and melancholy notes of Norna of Fitful-head, for the purpose of chanting some wild Runic rhyme, resembling those sung by the heathen priests of old, when the victim (too often human) was bound to the fatal altar of Odin or of Thor.

At length the two sisters at once started from sleep, and, uttering a low scream of fear, clasped themselves in each other’s arms. For their fancy had not altogether played them false; the sounds, which had suggested their dreams, were real, and sung within their apartment. They knew the voice well, indeed, and yet, knowing to whom it belonged, their surprise and fear were scarce the less, when they saw the well-known Norna of Fitful-head, seated by the chimney of the apartment, which, during the summer season, contained an iron lamp well trimmed, and, in winter, a fire of wood or of turf.

She was wrapped in her long and ample garment of wadmaal, and moved her body slowly to and fro over the pale flame of the lamp, as she sung lines to the following purport, in a slow, sad, and almost an unearthly accent:

“For leagues along the watery way,
Through gulf and stream my course has been;
The billows know my Runic lay,
And smooth their crests to silent green.
“The billows know my Runic lay,—
The gulf grows smooth, the stream is still;
But human hearts, more wild than they,
Know but the rule of wayward will.
“One hour is mine, in all the year,
To tell my woes,—and one alone;
When gleams this magic lamp, ’tis here,—
When dies the mystic light, ’tis gone.
“Daughters of northern Magnus, hail!
The lamp is lit, the flame is clear,—
To you I come to tell my tale,
Awake, arise, my tale to hear!”

Norna was well known to the daughters of Troil, but it was not without emotion, although varied by their respective dispositions, that they beheld her so unexpectedly, and at such an hour. Their opinions with respect to the supernatural attributes to which she pretended, were extremely different.
