After several hours spent in dozing and dreaming by "fits and starts," I was again fairly awake, and could sleep no more for thinking of the great rat. Indeed, the pain I suffered was of itself sufficient to keep me awake; for not only my thumb, but the whole hand was swollen, and ached acutely. I had no remedy but to bear it patiently; and knowing that the inflammation would soon subside and relieve me, I made up my mind to endure it with fortitude. Greater evils absorb the less; and it was so in my case. My dread of the rat paying me another visit was a far greater trouble to me than the pain of my wound, and as my attention was wholly taken up with the former, I almost forgot that my thumb was aching. As soon as I was well awake, my thoughts returned to the subject of trapping my tormentor. I was quite sure he would return to trouble me, for I already had some indications of his presence. The weather still continued calm, and I could hear any occasional sounds very distinctly. I heard what resembled the pattering of little feet, as of the rat running over the lid of an empty box; and once or twice I clearly distinguished the short, shrill cricket-like "chirp" that rats are wont to utter. I can think of no more disagreeable sound than the voice of a rat, and at that time it sounded doubly disagreeable. You may smile at my simple fears, but I could not help them. I could not help a presentiment that somehow or other my life was in danger from the presence of this rat, and the presentiment was not a vain or idle one, as you shall afterwards learn. The fear that I had, then, was that the rat would attack me in my sleep. So long as I might be awake, I was not much afraid that it could do me any very great injury. It might bite me, as it had done already, but that signified little. I should be able to destroy it somehow. But supposing I should fall into a deep sleep, and the spiteful creature should then seize me by the throat? Some such idea as this it was that kept me in misery. I could not always keep awake and on the _qui vive_. The longer I did so, the more deeply would I slumber afterwards, and then would be the time of danger. I could not go to sleep again with any feeling of security until that rat was destroyed; and therefore its destruction was the end I now aimed at.
