RIVERS.--The Doce, which is the largest of the comarca, has its origin in the serra of Mantiqueira. After flowing for a considerable space to the north-north-east, under the name of Chopoto, it receives the Piranga, which runs from the serra of Oiro Branco; afterwards the Guallacho, formed by two streams of the same name distinguished by the appellations of north and south, and which issue from the serra of Oiro Preto. At this confluence it inclines to the east, and gathers the Bombaca and the Percicaba, which flow from the west, and have their sources in the Serra Lapa. Here it takes the name by which it enters the ocean. A little lower it is united also on the left, by the considerable river St. Antonio, which comes from the north-west, traversing an extensive territory, abounding mainly in cattle. Of the streams which form it, some descend from the Serra Lapa, others from Serro Frio. Ten miles further, it is joined on the same side by the Corrente, which flows from Serro Frio, with more than one hundred miles of course. Thirty miles lower, it receives the large Sassuhy, whose heads emanate from the serras of Serro Frio and Esmeraldas; its margins are thinly inhabited. After it follows the Laranjeiras, in the same direction, between woods abounding with wild beasts and savages. The Cuyate, which runs north-east, is the largest of those which enter it on the right; its mouth is a little below the preceding, and it gives the name to an interior district inhabited by Indians. The Manhuassu, (which some say is larger than Cuyate,) after flowing through large woods north-eastward, and bounding the certam of Cuyate, is lost in the Doce, a little above the Escadinhas. Amongst others, the Doce has four remarkable falls: Escura, a little below the mouth of the Percicaba; Magoaris, a short way below the Corrente; Ibiturunas, a short distance above the Sassuhy; and Inferno, between the confluences of the Cuyate and the Manhuassu. The adjacent territory of this fine river is mostly of great fertility; in some places the root of the mandioca grows to a prodigious size. Independently of the above obstacles, the Doce is navigable for a great extent, and I was assured by an ouvidor, having a neighbouring jurisdiction, that no very great expenditure on the part of the government would render it the most important and certainly the best medium of transit for the produce of the interior districts of Brazil. The Maquipoo is one of its first tributaries received on the right, and enters a little above the mouth of the Bombaca. The Preto originates in the serra Ititiaya, a branch of the Mantiqueira range, and runs eastward through the territory of the Ararys, bounding the province, until it enters the Parahibuna, which latter rises near the Chopoto, and flows into the Parahiba.
