The picturesqueness of the Paraná River scenery along its upper courses has excited enthusiastic descriptions from all the travelers who have penetrated this marvelous country. A thousand miles up the river, in Misiones, near the point where Argentina, Paraguay, and Brazil meet, are located the famous Iguazú Falls. The great cascade, fifty feet higher and with a lateral extent 1250 feet greater than Niagara, lies in the midst of a primeval forest. The enormous volume of water bursts through a series of thickly wooded islands with a roar that is all the more impressive to the spectator because of the solitude that reigns throughout this scantily populated region. The hand of man has done nothing here—no attempt has been made to harness the mighty power; nature has been left alone to revel in utter abandon. ------------------------------------------------------------------------ IV URUGUAY One of the first inquiries that engages the mind of the visitor to Uruguay and Argentina is why the great body of water that separates the two countries—apparently an arm of the sea—should not be called the _Gulf_ of La Plata. After a brief stay in this region of great cities, great productiveness, and great opportunities, it will probably occur to him that dwellers among such great things could be satisfied with nothing less than an estuary of the broad Atlantic to serve as a river for their capitals. If the Paraná and Uruguay—mighty rivers which rank in size immediately behind the Mississippi—had joined their floods some miles above Buenos Aires, instead of flowing separately into La Plata, a stream of unquestionable status might have satisfied their demands; but the God of Waters willed otherwise, evidently not anticipating the greatness of these people and their illimitable ambition. The exact point at which La Plata River merges with the Atlantic is also a matter of speculation among geographers. For all practical purposes, however, Montevideo, the capital, metropolis, and chief port of Uruguay, lies just beside this phenomenon. One can say, therefore, that the eastern side of the little peninsula on which the main city is built faces the ocean, while the southern and western fronts, bordering the bay of the actual port, look upon the river Plata.
