While Europe had thus consumed centuries in improving paths of trade, until merchandise could be brought by canal a few score miles from the Rhone to the Loire and Seine, to the Garonne and the Rhine, and while all her wealth and energy had not yet united the Danube with other river systems, America was required to construct, without delay, at least three great roads and canals, each several hundred miles long, across mountain ranges, through a country not yet inhabited, to points where no great markets existed,—and this under constant peril of losing her political union, which could not even by such connections be with certainty secured.
