17．
During all this time，I never stopped thinking about escape．When I travelled across to the other side of the island，I could see the other islands，and I said to myself，"Perhaps I can get there with a boat．Perhaps I can get back to England one day．"
So I decided to make myself a boat．I cut down a big tree，and then began to make a long hole in it．It was hard work，but about six months later，I had a very fine canoe（独木舟）．Next，I had to get it down to the sea．How silly I was!Why didn't I think carefully before I began to work？Of course，the canoe was too heavy．I couldn't move it!I pulled and pushed and tried everything，but it didn't move．I was very unhappy for a long time after that．
In my sixth year on the island，I did make myself a smaller canoe，but I did not try to escape in it．The boat was too small for a long journey，and I did not want to die at sea．The island was my home now，and I was just happy to be alive．A year or two later，I made myself a second canoe on the other side of the island．I also built myself a second house there，and so I had two homes．
I kept food and tools at both of my houses，and also wild goats．There were many goats on the island，and I made fields with high fences to keep them in．They learnt to take food from me，and soon I had goats'milk to drink every day．I also worked hard in my corn fields．And so，many years went by．
