Along the coast, which runs from Cape St. Mary to the little Castilhos, are various lakes approximating to the sea. The lake Manglieira, which is eighty miles long and about four broad, extends between the coast and the lake Mirim, and empties itself, at the northern extremity, by an outlet called Arroio Thahim. The peninsula between the coast and the lake of Patos, from two to six leagues in width, is interspersed with a great number of lakes, generally running into the ocean, or into others. Amongst those extending westward we may remark, in the southern part, the Capibaras, into which a small river empties itself of limpid water, bursting suddenly forth with admirable force, and is the purest in the peninsula, which, nevertheless, is not deficient in good potable waters. On the eastern side of the peninsula is the lake Mostardas, better known by the name of Peixe, nine leagues long, with little width, extending along the margin of the sea to the point where it disembogues through an elbow of land, that opens and closes annually, and by which various species of fish enter; the most numerous are denominated _miragarga_, resembling the cod-fish. With this lake various others communicate, that lie to the north, and are connected by their different mouths. Near the last, that terminates the extent of the Barros Vermelhos, another chain of a similar description commences, at a short distance from the beach, and extends parallel with it for a space of twenty-five leagues. A short way from Barros Vermelhos, and by the side of the sea, there is a small lake that runs into a larger one, which terminates in the Capoes do Retuvado. It has an outlet into another, that extends from hence a league and a half. Beyond these there are two lakes running parallel; and still further another, near the Capao do Xavier, a distance of two leagues, which discharges itself into the lake Charqueada, the latter terminating in the place of that name, and running by a vein into a smaller one: this empties itself into a lake of equal size, and that is joined to a larger, which terminates in the Capao Dastacoáras. The last discharges itself into the Quintao, which runs into the Cidreira. The Cidreira is divided into three bays or lakes, communicating by necks or outlets, and occupying an extent of four leagues and a half. It has a channel of two miles long to the Ribeiro, terminating near the passage of the Arroio, its outlet to the river Tramandahy. The river Tramandahy is in 30° south latitude, and is nothing more than the channel of discharge to a great number of lakes, spreading themselves over the extensive plains that lie between the beach and the cordillera. Into this river also is discharged the most southern of another chain of lakes, that extend themselves along the same cordillera northward, very near to the river Mombituba, at the mouth of which there is a military detachment, in order to register persons entering or leaving the province.
