Extent Of American Territory The territory of the United States extends over an area of more than 2,000,000 square Its extreme length is nearly 2,700 miles, and its greatest breadth 1,600 miles. Its general shape may be considered a parallelogram, 2,400 miles by 1,600. The value of our harvests in the year 1850 exceeded $1,000,000,000. At that time there were 113,000,000 of acres under cultivation, and 180,000,000 more were included within the limits of farms, making, in all, 293,000,000 acres. It will thus be seen, by a comparison with European census statistics, that this fell short, by only some 30,000,000 acres, of the total amount of the improved lands within the limits of the four great European powers viz., - Great Britain, France, Austria and Prussia
