This interesting map shows a very transitional United States as it expands towards the Pacific Ocean in the middle of the 19th century. A detailed map of the northern United States is inset in the left of the main map. Michigan, Wisconsin, and Arkansas are territories with the Upper Peninsula of Michigan belonging to Wisconsin. The large Missouri Territory extends to the Canadian border and west to the boundary of Oregon Territory that encompasses the present-day states of Oregon, Washington and Idaho. Texas is named as a Spanish province, and a note above the Red River reads, "The desert is traversed by herds of Buffaloes & wild Horses & inhabited only by roving tribes of Indians." A detailed key in the lower right notes various sizes of cities, universities, missionary stations, Indian villages, trading houses, and forts.
