The price to be paid for this vast domain was fifteen million dollars. The area of the country ceded was reckoned to be more than one million square miles, greater than the total area of the United States, as the Republic then existed. Roughly described, the territory comprised all that part of the continent west of the Mississippi River, bounded on the north by the British possessions and on the west and south by dominions of Spain. This included the region in which now lie the States of Louisiana, Arkansas, Missouri, Kansas, parts of Colorado, Minnesota, the States of Iowa, Nebraska, South Dakota, North Dakota, Wyoming, a part of Idaho, all of Montana and Territory of Oklahoma.
