Three Years of Arctic Service

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. In preparing a popular edition in English, the same plan and scope have been followed as were pursued in the French and German editions. All the photographic reproductions have been retained, and only such por tions of the text have been omitted as bear on scientific and historical matters, unessential to a full understand ing of the expedition.
