The annual report of the General Land Office for 1869. These reports were issued in a number of foreign languages, presumably for the use of emigrants. Of particular interest is the huge color folding map, prepared under the direction of John P. Wilson, showing all of the United States and territories, including western rail lines, Indian reservations, surveyed townships, and other important geopolitical information. Having first appeared in the General Land Office report of 1866, it is one of the largest and most complete maps issued to that time, measuring (opened) 139 by 72 cm.
