赤道旅行记-Following the Equator（英文版）:
Following the Equator
by Mark Twain
THIS BOOK
Is affectionately inscribed to
MY YOUNG FRIEND
HARRY ROGERS
WITH RECOGNITION
OF WHAT HE IS, AND APPREHENSION OF WHAT HE MAY BECOME
UNLESS HE FORM HIMSELF A LITTLE MORE CLOSELY
UPON THE MODEL OF
THE AUTHOR.
THE PUDD-NHEAD MAXIMS.
THESE WISDOMS ARE FOR THE LURING OF YOUTH TOWARD
HIGH MORAL ALTITUDES.  THE AUTHOR DID NOT
GATHER THEM FROM PRACTICE, BUT FROM
OBSERVATION.  TO BE GOOD IS NOBLE;
BUT TO SHOW OTHERS HOW
TO BE GOOD IS NOBLER
AND NO TROUBLE.
