The island of Marambaya is high and rocky, and overspread with wood. The whole of its cultivation and population arises alone from the establishment of two sugar works upon it; and it possesses a hermitage of Our Lady of Griefs (_das Dores_.) From this island, a narrow sand-bank stretches to the east for six leagues, as far as the bar of Guaratiba, and is covered in the greatest part with vegetation. Over the bay of Angra dos Reys, a vast number of islands are scattered, amongst which may be enumerated the Supituba, Cunhambyba Grande, Jorge, Palmeira, Algodao, Barra, Caeyra, Redonda, Rafael, Cavaco, Pimenta, and another, also called Jorge, which are each from about a mile to two miles in length. The Gipoya, about six miles long, has some indigo works and fisheries; the Bomfim, very small, has a hermitage of the same name; the Tacoativa, Jacarahy, Paixao, Francisco Nunes, Barro, Pedreiro, Bayacica, Cana, Porcos, Sappe, Boqueirao, Redonda, Buzios, Casca, Brandao, Coco, Algodao, Ferreira, Cavaco, Jappam, Papagayos, Cobras, Sandre, and St. Joam are all small. The majority of these islands are partly cultivated and peopled. CAPES.--Cape Frio is the only remarkable cape of the province. That of St. Thomé is situated about twenty leagues north-north-east from it. The principal projecting points are Negra Point, nine leagues to the west of Cape Frio; Buzios Point, four leagues to the north-north-east of the same cape; and Guaratiba Point, near the bar of its name. The mother-church of the parish of St. Salvador is beautifully situated upon a small eminence in front of the bar of Guaratiba. Its district is twenty miles long, and fifteen wide. In the year 1804, it contained four thousand three hundred and forty inhabitants, dispersed over the parish, the vicar’s house being almost the only one in the vicinity of the church. ISLANDS.--The islands of this province are numerous, but the greater part inconsiderable, and principally within the two bays already described. Outside of the bar of Rio de Janeiro are the three islands of Palmas; also the islands of Redonda, Comprida, Raza, Cagada, Lage, Catunduda, Toacinho, Pay, and May; the whole of which are small, uninhabited, and extremely barren, except in verdant shrubs and brushwood. MINERALOGY.--This province has some mines of gold, and possesses veins of iron. The rocks of granite are very large and remarkable, being of one solid piece, from whence entire obelisks might be hewn of an immense size. Aqua-marinas are met with; and a variety of different earths, some considered equal to that with which the Chinese manufacture their porcelain. ZOOLOGY.--In this province are found all the domestic and wild animals belonging to the adjacent provinces, with a sort of Sahium monkey, hairy, and of a gold colour. Amongst the birds are remarked various sorts of the beautiful sahy, not met with northward.
