A traveler recounts a journey across Siberia, combining first-hand narrative with material drawn from other sources. Much attention is given to prisons, exile life, and penal mines, with descriptions of conditions, administration, and meetings with authorities and former prisoners. The narrative also records geographic and natural-history observations, practical travel experiences, and statistical or documentary notes. Appendices, illustrations, and maps complement the text by supplying bibliographic, scientific, and cartographic detail.
