11. Robinson and "Friday" built a canoe.
Under Robinson's guidance, "Friday" quickly learned to dress, shoot, speak English, believe in Christ... and became Robinson's most loyal servant and friend. In order to reach the mainland opposite the isolated island, Robinson wanted to build a canoe with "Friday". Since he was eager to think about the boat, he got to work without much thought. As a result, the wooden boat that took several months to be hewn from a big cypress tree was abandoned because it was too big.
A few years later, Robinson learned his lesson and built a smaller canoe along the river, installed a mast and sails, and cut many useful things inside the canoe. A slot to put things in. But because the canoe was too small, Robinson could not take it to the opposite continent and could only use it nearby.
