egg, supply the aliment of the Indian. The river Mondego, otherwise Embotateu, originally Aranbahi, is considerable, and navigable nearly to its origin, which is a short distance from that of the Anhanduhi Guaçu, and runs into the Paraguay eighteen miles below the Tocoary. The largest of its tributaries, which enter by the right margin, is now called the river Verde. The last confluent of the Mondego, by the southern bank, is the small river Zezere, which rises near the inconsiderable serra of St. Barbara. The Ivinbeima, which enters the Paranna by three mouths, flows from the interior of the province, whither it affords navigation; and receives by the left the Jaguary, a river little inferior to it. The Negro, which is considerable, and would appear to be the Sambambaya of the first certanistas, runs into the Paranna twenty miles above the northern mouth of the Ivinheima. The Miamaya, or Miamay, which is considered to be the river formerly called Amambahy, is large, and enters the Paranna forty miles below the southern arm of the Ivinheima. The Igatimy, to which is given one hundred and fifty miles of extent, is navigable very near to its source in the serra Amambahy. Eighty miles in a direct line from its embouchure is the passage of the Guaycurus, where the river is shallow. Twenty miles lower it receives on the left the small river Bogas; and thirty-five miles further, on the same side, the Escopil, which is little inferior, and flows from the same serra. The name of this fine confluence is Forquilha. It is an advantageous point for the establishment of a colony. From hence to the Paranna, the distance is about thirty-five miles, with only two falls. Ten miles above this point, the first of twenty-one falls is encountered, all of them compressed within the space of ten miles; from these cataracts upwards, the river has no interruption to a little above the Guaycuru ford, already mentioned. The course is winding, the lateral lands low, and covered with impervious woods. The Correntes, which appears to be the same that the Spaniards called Rio Branco, (White River,) is considerable, and enters the Paraguay fifty miles below the _Fecho dos Morros_, (closing of Rocks.) The Ipanne Guaçu, after having watered an uninhabited territory, falls into the Paraguay one hundred miles below the Correntes.
