The planks, fortunately, having been nailed together fresh, had shrunk considerably, so as to leave wide chinks between each and its neighbour. By means of these apertures I saw that my dungeon was secured, not by a lock, as I had feared, but by a strong wooden bar, running horizontally across the door, about midway upon the outside. 'Now,' thought I, 'if I can but slip my fingers through the opening of the planks, I can easily remove the bar, and then----' My attempts, however, were all frustrated by the manner in which my hands were fastened together, each embarrassing the other, and rendering my efforts so hopelessly clumsy, that I was obliged to give them over in despair. I turned with a sigh from my last hope, and began to pace my narrow prison floor, when my eye suddenly encountered an old rusty nail or holdfast sticking in the wall. All the gold of Plutus would not have been so welcome as that rusty piece of iron. I instantly wrung it from the wall, and inserting the point between the planks of the door into the bolt, and working it backwards and forwards, I had at length the unspeakable satisfaction to perceive that the beam was actually yielding to my efforts, and gradually sliding into its berth in the wall. I have often been engaged in struggles where great bodily strength was required, and every thew and sinew in the system taxed to the uttermost; but, strange as it may appear, I never was so completely exhausted and overcome by any labour as by this comparatively trifling task. Again and again was I obliged to desist, until my cramped finger-joints recovered their power; but at length my perseverance was rewarded, for, little by little, I succeeded in removing the bolt so far as to allow the door to open sufficiently to permit me to pass. With some squeezing I succeeded in forcing my way into a small passage, upon which my prison-door opened. This led into a chamber somewhat more spacious than my cell, but still containing no furniture, and affording no means of escape to one so crippled with bonds as I was. At the far extremity of this room was a door which stood ajar, and, stealthily passing through it, I found myself in a room containing nothing but a few raw hides, which rendered the atmosphere nearly intolerable. Here I checked myself, for I heard voices in busy conversation in the next room. I stole softly to the door which separated the chamber in which I stood from that from which the voices proceeded. A moment served to convince me that any attempt upon it would be worse than fruitless, for it was secured upon the outside by a strong lock, besides two bars, all which I was enabled to ascertain by means of the same defect in the joining of the planks which I have mentioned as belonging to the inner door. I had approached this door very softly, so that, my proximity being wholly unsuspected by the speakers within, the conversation continued without interruption.
