The first approaches of the morning were visible through the grated windows, breaking, with faint divisions of light, the darkness that still pervaded every other part, long before Vivenzio was enabled to distinguish any object in his dungeon. Instinctively and fearfully he turned his eyes, hot and inflamed with watching, toward them. There were FOUR! He could _see_ only four: but it might be that some intervening object prevented the fifth from becoming perceptible; and he waited impatiently to ascertain if it were so. As the light strengthened, however, and penetrated every corner of the cell, other objects of amazement struck his sight. On the ground lay the broken fragments of the pitcher he had used the day before, and, at a small distance from them, nearer to the wall, stood the one he had noticed the first night. It was filled with water, and beside it was his food. He was now certain, that, by some mechanical contrivance, an opening was obtained through the iron wall, and that through this opening the current of air had found entrance. But how noiseless! for, had a feather even waved at the time, he must have heard it. Again he examined that part of the wall; but both to sight and touch it appeared one even and uniform surface, while, to repeated and violent blows, there was no reverberating sound indicative of hollowness. This perplexing mystery had for a time withdrawn his thoughts from the windows; but now, directing his eyes again toward them, he saw that the fifth had disappeared in the same manner as the preceding two, without the least distinguishable alteration of external appearances. The remaining four looked as the seven had originally looked; that is, occupying at irregular distances the top of the wall on that side of the dungeon. The tall folding-door, too, still seemed to stand beneath, in the centre of these four, as it had first stood in the centre of the seven. But he could no longer doubt what, on the preceding day, he fancied might be the effect of visual deception. The dungeon _was_ smaller. The roof had lowered; and the opposite ends had contracted the intermediate distance by a space equal, he thought, to that over which the three windows had extended. He was bewildered in vain imaginings to account for these things. Some frightful purpose, some devilish torture of mind or body, some unheard-of device for producing exquisite misery, lurked, he was sure, in what had taken place.
