Fearing, however, that the train of thought into which I fell might unsteady my nerves, I fully determined to keep my mind in a fit state to cope with whatever of marvelous the advancing night might bring forth. I roused myself; laid the letters on the table; stirred up the fire, which was still bright and cheering; and opened my volume of Macaulay. I read quietly enough till about half past eleven. I then threw myself dressed upon the bed, and told my servant he might retire to his own room, but must keep himself awake. I bade him leave open the door between the two rooms. Thus alone, I kept two candles burning on the table by my bed head. I placed my watch beside the weapons, and calmly resumed my Macaulay. Opposite to me the fire burned clear; and on the hearth rug, seemingly asleep, lay the dog. In about twenty minutes I felt an exceedingly cold air pass by my cheek, like a sudden draught. I fancied the door to my right, communicating with the landing place, must have got open; but no,--it was closed. I then turned my glance to my left, and saw the flame of the candles violently swayed as by a wind. At the same moment the watch beside the revolver softly slid from the table,--softly, softly; no visible hand,--it was gone. I sprang up, seizing the revolver with the one hand, the dagger with the other; I was not willing that my weapons should share the fate of the watch. Thus armed, I looked round the floor,--no sign of the watch. Three slow, loud, distinct knocks were now heard at the bed head; my servant called out, "Is that you, sir?" "No; be on your guard." The dog now roused himself and sat on his haunches, his ears moving quickly backward and forward. He kept his eyes fixed on me with a look so strange that he concentered all my attention on himself. Slowly he rose up, all his hair bristling, and stood perfectly rigid, and with the same wild stare. I had no time, however, to examine the dog. Presently my servant emerged from his room; and if ever I saw horror in the human face, it was then. I should not have recognized him had we met in the street, so altered was every lineament. He passed by me quickly, saying, in a whisper that seemed scarcely to come from his lips, "Run, run! it is after me!" He gained the door to the landing, pulled it open, and rushed forth. I followed him into the landing involuntarily, calling him to stop; but, without heeding me, he bounded down the stairs, clinging to the balusters, and taking several steps at a time. I heard, where I stood, the street door open,--heard it again clap to. I was left alone in the haunted house.
