Our boat floated on, between walls of forest too thick to allow us to see the land we were passing through, though we knew from the map that our river must from time to time be passing through hills. Nowhere did we find a place where we could have landed. Banks of soft mud prevented us going ashore (靠岸). In any case, what would we have done by landing? The country was full of snakes and other dangerous creatures, and the jungle was so thick that one would be able to advance only slowly, cutting one’s way with knives the whole way. So we stayed in the boat, hoping that when we reached the sea, a friendly fisherman would pick us up and take us to civilization.

We lived on fish, caught with a homemade net, and fruits and nuts we could pick up out of the water. As we had no fire, we had to eat everything, including the fish, raw. I had never tasted raw fish before, and I must say I did not much enjoy the experience.

One day we passed another village, but fortunately nobody saw us. We did not wish to risk being taken prisoners a second time: we might not be so lucky to get away in a stolen boat again.
