As the alarm and inquiry subsided, their father made them, now and then, a brief and stealthy visit. At first these were but of a night's duration, and with great precaution; but gradually they were extended and less guarded. Still he was, as the phrase is in Munster, "on his keeping." He had firearms always by his bed, and had arranged places of concealment in the castle in the event of a surprise. But no attempt nor any disposition to molest him appearing, he grew more at ease, if not more cheerful. It came, at last, that he would sometimes stay so long as two whole months at a time, and then depart as suddenly and mysteriously as he came. I suppose he had always some promising plot on hand, and his head full of ingenious treason, and lived on the sickly and exciting dietary of hope deferred. Was there a poetical justice in this, that the little _ménage_ thus secretly established, in the solitary and timeworn pile, should have themselves experienced, but from causes not so easily explicable, those very supernatural perturbations which they had themselves essayed to inspire? The interruption of the old priest's secret visits was the earliest consequence of the mysterious interference which now began to display itself. One night, having left his cob in care of his old sacristan in the little village, he trudged on foot along the winding pathway, among the gray rocks and ferns that threaded the glen, intending a ghostly visit to the fair recluses of the castle, and he lost his way in this strange fashion. There was moonlight, indeed, but it was little more than quarter-moon, and a long train of funereal clouds were sailing slowly across the sky--so that, faint and wan as it was, the light seldom shone full out, and was often hidden for a minute or two altogether. When he reached the point in the glen where the castle-stairs were wont to be, he could see nothing of them, and above, no trace of the castle-towers. So, puzzled somewhat, he pursued his way up the ravine, wondering how his walk had become so unusually protracted and fatiguing.
