In the vicinity of the last isle, is the island of Grande, or Large Island, not being much less in extent than seventy miles, and of considerable width; it terminates four miles above the Seven Falls. A little more than seven miles above the southern point of this island, the river Iguatimy enters the Paranna on the western margin, in latitude 24° 40′; and in a little higher latitude the Piquiry. Ten miles to the south of the first, it receives, by the right bank, the small river Iguarei, nearest to the Seven Falls. At the extremity of the Great Island, the current of the Paranna is much accelerated, and augments proportionably as its margins approximate; and from near four miles of width, which it retains in front of the Iguarei, it diminishes to fifty fathoms, its immense volume of waters being then divided into seven channels, formed by six small islands of rock, traversing the serra of Maracaju, with a current of indescribable fury and awful noise. Besides the islands already mentioned in this river, there are a vast number of others, of a smaller size, in the great space that intervenes between the Setequedas and the fall of Urubu Punga. Its waters are turbulent, and ill adapted for drinking. The western margin is flat, in part consisting of a large white sand, with a variety of precious stones, for the space of many leagues without interruption. The eastern bank is generally a little elevated; and both exhibit continued and extensive woods. Without any considerable windings, it runs between the south and south-west, with a current generally slow and majestic; but, when strong winds prevail, the waves are as tumultuous as those of the ocean. It abounds with various kinds of fish, some of which are excellent. Forty miles below the Seven Falls, the river Jaguare enters the Paranna by the left margin; and sixty miles further the considerable Iguassu. At a considerable distance further, its direction is changed towards the west, and enters the Paraguay in the latitude of 27° 20′. From the mission of Corpus upwards, aboriginal nations alone possess the vast territory watered by this majestic river and its confluents.
