INDIANA.The following remarks upon the subject of Internal Improvements in Indiana, are copied from the Lawrenceburgh Palladiumof the 2d instant:The advantages resulting to the State of Indiana from the successful prosecution of this system are almost incalculable.— Under itg operations, more than a million of dollars will be annually scattered among the people for labor and the surplus produce of their farms, during the progress of those works. It will invite emigration from every part of the Union, as well as from foreign countries which will bring into our State not only a great accession of numbers, but of wealth and enterprise. Our immense tracts of vacant land will be soon taken up—the forest will be subdued —manufactures svill spring up among of, by which we will be supplied with many j articles of necessity which are now bro’t from abroad, and which are annually j draining our slate of the precious metals. j Our farms will be enhanced in value at least fifty per cent, on an average, and the surplus products of the soil will experience a corresponding advance. Towns, which have heretofore been moving onward with •low and measured tread, or which have been vasciMating, as it were, between hope and fear, uncertain whether they were advancing or receding, will suddenly break j the dull monotony which has hung around them for years, and spFing into active and vigorous life, and with a celerity unparal Jelled will grow up into large manufacturing and commercial cities. To the trav elier will be afforded the means of a cheap and speedy transit from one part of the State to another; and above all, the farmers in the interior of the Stale, will have a j safe and cheap outlet to market with the products of their labor. Such is but a faint outline of the great advantages resulting from this grand scheme of Internal Improvements,
