It may be, my dear grandchildren, that at one time or another I have told you nearly all the incidents which have occurred during my adventurous life. To your father and to your mother, at least, I know that none of them are unfamiliar. Yet when I consider that time wears on, and that a grey head is apt to contain a failing memory, I am prompted to use these long winter evenings in putting it all before you from the beginning, that you may have it as one clear story in your minds, and pass it on as such to those who come after you.
