Fifteen miles further along the coast is the large outlet of the considerable river Iguape, formed by a great number of large streams, generally serpentine, and watering a vast and mountainous country, having gold. This river is navigable for many leagues; and in the vicinity of the sea, describing large windings, forms many peninsulas, some of the isthmuses of which have been cut in order to shorten the navigation. It passes about two miles from the town of Iguape. Thirty-five miles further are the two mouths of the river Una, up which canoes proceed more than fifty miles, to a place called Prelado. Forty miles to the north-east is the entrance of the bay of Itanhaen, which is handsome, and takes the name of a small river discharged at its extremity. The bay of Santos follows at a distance of thirty-five miles, to which the island of St. Vincente, and that of St. Amaro, originally Guahibe, each being fifteen or eighteen miles long, open three entrances. The southern is denominated the bar of St. Vincente, the central Barra Larga, (Wide Bar,) or the bar of Santos, and the northern, Bertioga, by corruption Buriquioca, which signifies a house or cavern of _buriquis_, a species of monkey. It is the only port of the province capable of receiving armadas. Various small rivers, alone navigable with the tide, flow hither, and are discharged amidst mangroves. ISLANDS.--The two last islands are the principal; are elevated, and abound with water, timber, and good stone. The island of St. Amaro has scarcely any inhabitants, and is almost entirely uncultivated, which, perhaps, is owing to its not having been granted at first in small portions to agriculturists capable of cultivating it. About thirty miles to the east-north-east of St. Amaro, is the island of St. Sebastian, fifteen miles long, and proportionably wide, also high, with some inhabitants and roadsteads, being separated from the continent by the profound channel of Toque-Toque, a league in width. Fifteen miles to the north-east from hence is the small island of Porcos, which is of a triangular form, with good anchorage in its vicinity, and inhabited. In the same direction, and at an equal distance, the island of Couves is situated, possessing good water, and commodious anchorage on the side next the continent, from which it is distant three miles. The Queimadas, consisting of three small islands, are situated twelve miles east of the entrance to the bay of Itanhaen.
