What did Kimki leave the island in?

Kimki left the island in a canoe.

In the spring, Kimki called the tribe together. He had been thinking, he said, during the winter and had decided that he would take a canoe and go to the east to a country which was there and which he had once been to when he was a boy. It lay many days across the sea, but he would go there and make a place for us. He would go alone, because he could not spare more of our men for the voyage, and he would return.
