It may be necessary, however, to state here previously, that these mountains are remarkably--indeed proverbially--subject to deep, impervious mists, which wrap them in a darkness far more impenetrable to the eye than the darkest nights, and immeasurably more confounding to the reason, by at once depriving the individual whom they chance to overtake, of all sense of his relative position. At night the moon and stars may be seen, or even a fire or other light at a distance; but here, whilst enveloped in one of those dark and dismal fogs, no earthly object is seen within two yards of you, and every step made is replete with doubt or danger, and frequently with death itself, in the shape of deep shoreless lakes and abrupt precipices. The night had now set in for about two hours, and one of the deep fogs which we have just described began to break into broad gray fragments, which were driven by the wind into the deeper hollows, dissipated almost at once into the thin and invisible air. Sometimes a rush of wind would sweep along like a gigantic arrow, running through the mist, and leaving a rapid track behind it like a pathway. Sometimes again a whirl-blast would sweep round a hill, or rush up from a narrow gorge, carrying round, in wild and fantastic gyrations, large masses of the apparently solid mist, giving thus to the scene such an appearance as would lead the spectator to suppose that some invisible being or beings, of stupendous power, were engaged in these fearful solitudes. The night, we have said, had set in, and the mist was clearing, or had altogether cleared away. Up far in these mountains lived a herd, or caretaker and gamekeeper, all in one, named Frank Finnerty. He was a man of bad character--gloomy, sullen, and possessed of very little natural feeling. The situation in which he resided was so remote and solitary, so far from the comforts and conveniences that are derived from human intercourse, that scarcely any other man in the parish could be induced to undertake the duties attached to it, or consent to live in it at all. Finnerty, however, was a dark, unsocial man, who knew that he was not liked in the country, and who, on his part, paid back to society its hatred of him with interest. He had been engaged in many outrages against the law, and had been once sentenced to transportation for manslaughter--a sentence which would have been carried into effect were it not for a point made m his case by the lawyer who defended him--His wife was a kind-hearted, benevolent woman naturally, but she had been for years so completely subdued and disjointed, that she was, at the period we write of, a poor, passive, imbecile creature, indifferent to everything, and with no more will of her own than was necessary to fulfil the duties of mere mechanical existence. It was now near ten o'clock; Finnerty and she had been sitting at the fire in silence for some time, when at length she spoke.
