a city of the United States of North America, capital of Indiana, on the White River. 109 miles N.W. from Cincinnati. It is situated in an extensive and fertile plain, near the centre of the state. The town is regularly built, and the streets generally cross each other at right angles. The state-house, an elegant building, 180 feet in length by 80 in width, is surmounted by a dome, and has ten Doric columns in front. There are several iron foundries, flour mills, and manufactories of steam-engines, paper, &c. Indianapolis is the terminus of seven railroads, viz.—the Madison and Indianapolis; the Lafayette; the Terre Haute and Indianapolis; the Indiana Central; the Indianapolis and Bellefontaine; the Peru and Indianapolis; and the Laurenceburg and Upper Mississippi railroad. Nearly all of the above are now in operation. Pop. (1853) about 12,000.
