spoken to each other we might have regained some courage, but we were paralyzed with nervous fear; our throats were parched, and our muscles rigid with long continued tension, for we dared not move. It was like a spell, and the fact that we did not know what it was we feared, made the fear all the more intense. At length, after what seemed a century of suffering, the strange footsteps paused. Our hearts gave a leap. Was it coming in? Who was it? Would it come and stand by the bedside, and look at us in the darkness? No! Slowly--and steadily it went down the stairs. We counted every step to the bottom. Then a pause. Would it go towards the dining-room, where the silver was, or towards the sleeping-rooms? We almost hoped it would, for that would prove a desire for plunder. Still silence! We dared not move for fear it might have crept softly up the stairs; it might even now be crawling towards us in the darkness. We shuddered; the silence seemed worse than the regular footfalls. Suddenly we heard a distinct snap in the hall below. We instantly recognized the bolt of the front door, and simultaneously we sprang from the bed. _It_--whatever _It_ was,--was going.

It, whatever it was, had entered, passed up the stairs, spent the night pacing to and fro in the upper hall, and then, just before dawn, had departed as strangely as it came. "'Who or what it was, we never knew. The only possible solution was, that it might have been some somnambulist; and, in that case, it must have been some acquaintance who bad been in the house in his waking moments. But even this solution seemed unsatisfactory, and finally Kate and I gave up trying to solve the enigma, content to let it rest as the mystery of our Unseen Visitor. SIBYL WARRINGTON.'" "Oh, Sibyl! you never told us anything about it before!" exclaimed Gem, who had listened with breathless interest. "Is it all really true?" "Entirely true," replied Sibyl; "it is an exact description of what happened during my visit to C------ last summer." After a little general conversation upon somnambulism, and the stories connected with it, Hugh took up another paper. "Ladies and gentlemen," he said, "the next manuscript, which I have taken at random from the basket, seems to be poetical. It is prefaced by the following note:--
