I set to work, without further delay, to widen the hole crossways; but the blade, from so much use, had become "dull as a beetle," and my progress through the hard oaken stave was as slow as if I had been cutting through a stone. I carved away for a quarter of an hour, without making the notch the eighth part of an inch deeper; and I almost despaired of ever getting through the stave. I now felt the singular influence again coming over me, and could have remained without much fear, for such is the effect of intoxication; but I had promised myself that the moment I became aware of any change, I should retreat from the dangerous spot. Fortunately, I had resolution, and barely enough, to keep my promise; and, before it was too late, I dragged myself back to the rear of the water-butt. It was well I did so at the very time, for had I remained in the brandy-cask but ten minutes longer, beyond doubt I should have been hopelessly insensible. As it was, I already felt quite "happy," and remained so for some time. But as the alcoholic influence departed, I grew more miserable than ever; for I now perceived that this unexpected obstacle to my progress was about to ruin all my hopes. I believed that I could return at intervals, and go on with the work; but only at long intervals, and now that the blade of my knife had grown so blunt, I could make but little progress. It would be days before I should get through the side of the cask; and days were denied me. The small store of crumbs were sadly reduced; in fact, I was on my last handful. I had not enough to keep me alive for three days! The chances of saving my life were growing narrower with every fresh move, and I was fast giving way to despair. Had I been sure that after cutting through the cask, I should have found relief on the other side, I might have contemplated the enterprise with more eagerness and energy; but this was worse than doubtful. There were ten chances to one against my finding a box of biscuits, or anything that was eatable. One advantage had arisen from my breaking into the brandy-cask, which now occurred to me in full force. It had given me a large empty space; and therefore, if I could only get beyond--even though there should not be a package containing food--still it might be something which I could remove into the inside of the cask, and thus make way for further operations. This was certainly a fresh phase which my situation had assumed; but a still better idea succeeded, that lent a new and joyous aspect to my thoughts. It was this: if I could so easily cut my way from box to box, as I had already proved, _why might I not tunnel upwards, and reach the deck_? The thought startled me. It was quite new. It had not occurred to me before--strangely enough it had not--and I can only explain its tardy conception by the fact of the confused state of mind in which I had all along been, and which might have led me to deem such an enterprise an impossibility.
