“Someone who knows enough to become the owner of a tree, and gives thanks to you for the benefits it brings him, is in a better state, even if ignorant of its height in feet and the extent of its spread, than another who measures and counts all its branches but neither owns it nor knows its creator nor loves him.”

“If I could do this book properly it would be one of the really fine books and a truly American book.
