While I wondered, chancing to glance behind me, I saw the fin of a shark standing above the water not twenty paces away, and advancing rapidly towards me. Then terror seized me and gave me strength and the wit of despair. Pulling down the edge of the barrel till the water began to pour into it, I seized it on either side with my hands, and lifting my weight upon them, I doubled my knees. To this hour I cannot tell how I accomplished it, but the next second I was in the cask, with no other hurt than a scraped shin. But though I had found a boat, the boat itself was like to sink, for what with my weight and that of the rotten meal, and of the water which had poured over the rim, the edge of the barrel was not now an inch above the level of the sea, and I knew that did another bucketful come aboard, it would no longer bear me. At that moment also I saw the fin of the shark within four yards, and then felt the barrel shake as the fish struck it with his nose. Now I began to bail furiously with my hands, and as I bailed, the edge of the cask lifted itself above the water. When it had risen some two inches, the shark, enraged at my escape, came to the surface, and turning on its side, bit at the tub so that I heard its teeth grate on the wood and iron bands, causing it to heel over and to spin round, shipping more water as it heeled. Now I must bail afresh, and had the fish renewed its onset, I should have been lost. But not finding wood and iron to its taste, it went away for a while, although I saw its fin from time to time for the space of some hours. I bailed with my hands till I could lift the water no longer, then making shift to take off my boot, I bailed with that. Soon the edge of the cask stood twelve inches above the water, and I did not lighten it further, fearing lest it should overturn. Now I had time to rest and to remember that all this was of no avail, since I must die at last either by the sea or because of thirst, and I lamented that my cowardice had only sufficed to prolong my sufferings. Then I prayed to God to succour me, and never did I pray more heartily than in that hour, and when I had finished praying some sort of peace and hope fell upon me. I thought it marvellous that I should thus have escaped thrice from great perils within the space of a few days, first from the sinking _carak_, then from pestilence and starvation in the hold of the slave-ship, and now, if only for a while, from the cruel jaws of the sharks. It seemed to me that I had not been preserved from dangers which proved fatal to so many, only that I might perish miserably at last, and even in my despair I began to hope when hope was folly; though whether this relief was sent to me from above, or whether it was simply that being so much alive at the moment I could not believe that I should soon be dead, is not for me to say.
