But here I had like to have suffered a second shipwreck, which, if I had, I think verily would have broken my heart; for, knowing nothing of the coast, my raft ran aground at one end of it upon a shoal, and not being aground at the other end, it wanted but a little that all my cargo had slipped off towards the end that was afloat, and to fallen into the water.
All that I could do was to wait till the tide was at the highest, keeping the raft with my oar like an anchor, to hold the side of it fast to the shore, near a flat piece of ground, which I expected the water would flow over; and so it did.
Contented with this discovery, I came back to my raft, and fell to work to bring my cargo on shore, which took me up the rest of that day.
