A few words may be expected in this connection upon the new matter, by the introduction of which the single volume of Pike has been extended to three volumes, thus more than doubling the original text. I have seldom, if ever, studied a work whose author seemed to me in so great need of an interpreter. Pike was not always precise in his statements of fact, and sometimes failed to convey his own meaning with entire lucidity. Much was thus left to be supplied by the imagination of the reader, or to be clarified by the exercise of his critical faculties, whether or no he were sufficiently informed in the premises to follow his author intelligently. In subjecting the text to a scrutiny, perhaps exceptionally close and rigid, I have desired in the first place to inform myself of the exact significance which the author intended his words to have, thus putting myself as nearly as possible in his place, and always, as I trust, in full sympathy with him, however diverse from his views any of my own opinions may have been. Coming to such understanding of the work in hand--one whose accomplishment is now nearly a century old--my duty seemed to be to criticise the subject-matter from the standpoint of to-day, however copious might prove to be the additional information required, or to whatever extent the resulting commentary might be protracted. This part of my work is represented by the notes with which the present edition has been freighted, and which are typographically distinguished from the main text. These notes bespeak their own variety and perhaps comprehensiveness; but of their value or interest it is not for me to express any opinion. Aside from this main exercise of an editorial function to the best of my ability, I have been induced to add another to the several good memoirs of Pike which we already possessed--notably Whiting's and Greely's. In the preparation of this I have been able to avail myself of much hitherto unpublished documentary material and other sources of information which have not before been utilized for this purpose. Under the circumstances of its present connection this biography could be prepared with little regard to Pike as an explorer, for these volumes cover all such ground; and thus I could dwell for the most part upon other aspects of his life and character, such as those which led up to his conspicuous adventures, and especially those of the War of 1812 which closed with his death a career of military honor and renown.
