All of these waterfalls, however, are overshadowed by the wonderful falls of the Iguassú, situated on the river of the same name, near its junction with the Paraná River, and on the borders between the republics of Brazil and Argentina. A dozen miles away the smoking columns of mist which crown the falls are plainly visible, and its thunderous roar may sometimes be heard for twenty miles. As one approaches nearer, the mist is more plainly seen and the roar of the waters is heard. The first view of these magnificent falls in their solitary grandeur is inspiring. They have the same general shape as Niagara, and are fifty feet higher. The entire falls are more than two miles in width, with a number of islands dividing the cataract. This may be divided into two sections, the Brazilian and Argentine falls. The head falls are on the Brazilian side and occur on an acute horseshoe bend, somewhat similar to that at Niagara, which is caused by the unequal erosion. Below the falls are depths which a hundred fathom line has failed to sound, and the natives call them bottomless. There is a triple leap of three hundred and twenty feet, the last one alone being a drop of two hundred and thirteen feet over sheer precipices of dark rock. At the present time it is difficult of access, because it is reached by ascending the Rio de la Plata and Paraná River, a journey of almost two weeks, or by a several days’ journey overland from Ponta Grossa, in the state of Paraná. Some day, when the means of communication become better, it will no doubt be visited by thousands of people each season. It still remains in all its primitive beauty, for the hand of man has as yet done nothing to detract from or add to what nature herself created. It is like another Niagara set out in the midst of a wilderness, with dense lines of waving bamboo or other trees marking the boundaries of the stream. Like Tennyson’s _Brook_, the Iguassú might say: “For men may come and men may go, But I go on forever.” [Illustration: FALLS OF IGUASSÚ.] Above these falls on the Paraná are the wonderful Guayra falls, one hundred and twenty-five miles above the junction with the Iguassú; and four hundred miles still farther up are the Uberaponga falls, with many smaller cataracts intervening. Below Guayra cataract the current piles up in the centre with a corkscrew action, and then dives down again into midstream. It returns to the surface in eddies which leap up twelve or fifteen feet in the air, making, as one scientific investigator terms it, “rapids with which the whirlpool rapids of Niagara are a quiet duckpond in comparison.” One is lost in considering this frantic water power here awaiting the harnessing by man.
