Unusually visually striking depiction of the islands of the Pacific. Relief shown by hachures. Late 1874 issue - the extra double page Oregon, California and Nevada map is undated and the inset map of the Bay Area shows a new railroad from Benicia, and other railroads projected. However, we cannot find any other changes from the early 1874 issue. Edition for the California market, with the extra map of Sacramento and the map of Oregon, California and Nevada. Full color throughout differentiating countries, states, and counties.
