I had built the raft close down to the water; but even so, I had considerable difficulty in getting it afloat.  I succeeded, however, in so doing at last, by means of a long piece of wood, which served me as a handspike.  Just as I was going to step on it, I fortunately saw the branch of a tree floating by out to sea, at a rate which showed me that I might very possibly be carried away by the current before I could get across.  I therefore converted my neckcloth and pocket-handkerchief into a tow-rope, and towed the raft inside the lagoon.  I had made myself two strong paddles--one to serve in case the other should break.  At last I reached a point where I thought I might embark with safety.  Surley, who had before hesitated, now came and placed himself by me.  I had put on my shirt again, but the rest of my things were on the small raft.  I gave my raft a desperate shove, and away I went, paddling as hard as I could up the lagoon.
