One consideration which deterred me was that, having kept no journal during a greater portion of the time in which I was absent, I feared I should not be able to write, from mere memory, a statement so minute and connected as to have the _appearance_of that truth it would really possess, barring only the natural and unavoidable exaggeration to which all of us are prone when detailing events which have had powerful influence in exciting the imaginative faculties. Another reason was, that the incidents to be narrated were of a nature so positively marvellous that, unsupported as my assertions must necessarily be (except by the evidence of a single individual, and he a half-breed Indian), I could only hope for belief among my family, and those of my friends who have had reason, through life, to put faith in my veracityâthe probability being that the public at large would regard what I should put forth as merely an impudent and ingenious fiction. A distrust in my own abilities as a writer was, nevertheless, one of the principal causes which prevented me from complying with the suggestions of my advisers.
