TRANSPORTATION. Indiana's natural means of transportation consists of the Ohio River, form ing the entire southern boundary of the State; its tributary, the Wabash, navigable at high water as far as Lafayette; and Lake Michigan on the north, with the single port of Michigan City. The National Road, running east and west through the central part of the State, played an important part during the pioneer period. as did also two canals—one, the Wabash and Erie, en tering the State at the northeast corner and run ning diagonally across it to Evansville in the southwest corner; the other, the White Water Canal, extending from Lawrenceburg in the south east corner of the State, north to Hagerstown. rut these have been superseded by railroads, and for a number of years have been abandoned. Railroads have come to he the principal means of communication, the State being most advan tageously placed in this respect. All lines from
the east centring in Chicago pass through the State, as do most of the lines connecting the great commercial centres of the East with those of the West, besides some important northern and southern lines. Of a total mileage of 6459, than 1000 miles of road have terminals within the State. There are 19 miles of railroad per 100 square miles of territory, and 24.91 miles for every 10.000 inhabitants. Recently there has been a remarkable development of cross-country electric ear lines, and apparently these will be come common in districts where local passenger traffic is great, or where railroad accommodations are wanting. Indiana has, in addition to one port of entry. two ports of delivery, Evansville and Indianapolis.
