What was the one thing of value that Kino owned, and how did he acquire it?

The one thing of value that Kino owned was his canoe. It was passed down to him by his father.

Kino and Juana came slowly down to the beach and to Kino's canoe, which was the one thing of value he owned in the world. It was very old. Kino's grandfather had brought it from Nayarit, and he had given it to Kino's father, and so it had come to Kino.
