What is the author's tone in Osborne Russell's Journal of a Trapper: Edited from the Original' by Osborne Russell?

The tone of the book is that of a young man going off on an exciting adventure. Especially in the first couple of years, Osborne Russell has a quiet sense of optimism. Russell's tone is that of a person who is glad to have the opportunity to live a life of which he had before dreamed. His extra efforts to learn the Snake Indian language and Indian sign language indicate him to be an intelligent person, though without any special studies or background. The vocabulary of the JOURNAL is not difficult but is that of an educated layman.
