Suddenly, a big steamboat came at us very fast, and the next minute it was right over us.
Jim and I jumped off the raft into the water. The boat hit the raft and went on up the river.
When I came up out of the water, I couldn’t see Jim anywhere. I called out his name again and again, but there was no answer.
‘He’s dead!’ I thought. Slowly, I swam to the side of the river and got out. I saw that I was near a big old wooden house.
Suddenly a lot of very angry dogs jumped out at me. They made a terrible noise and someone called from the house, ‘Who’s there?’
