If you turn to your map of South America you will note that on the east side of Paraguay (pr´ å-gw) Argentina extends northward in what appears to be a narrow strip of land. Between Paraguay and Argentina is the Parana River. There runs into the Parana River, forming the northern boundary of this strip of Argentina, the Iguazu (pronounced uh-wah-zu) River. This stream rises in the Serra do Mar Mountains on the extreme eastern coast of Brazil. Its upper heights are broken by falls and cascades, and on either side it is surrounded by semitropical forests. In twelve miles of its junction with the Parana, it breaks over the uplands of Brazil, into the valley, in the magnificent falls of Iguazu. As you see, most of the falls make double leaps to the deep gorge below. The largest is on the boundary line between Argentina and Brazil. This makes a single leap only, and this is a descent of 213 feet. Niagara's greatest height is 169 feet. Directly across from one end of the falls to the other, it is a distance of 6,000 feet, considerably over a mile. But if you measure around the various crests over which the waters break, and follow the windings of the falls, the distance across is barely short of two miles. The greatest length of Niagara is considerably less than a mile. In the dry season, the falls are broken up into 275 cascades such as are shown here. But in the rainy season the falls are one great body of foaming water. The loveliness of the Iguazu Falls is due to the fact that it is broken up into smaller falls, and that the islands so formed are covered with wonderfully rich vegetation. Argentina has already planned a great national park on her side of these falls. She expects, too, to harness them for electric power.
