Proceeding northward, the next river is the Cambory-Guassu, rapid at its entrance into the sea, and being twenty fathoms in width. Nearly three leagues farther is the embouchure of the great river Tajahy, which is little less than sixty fathoms in width at the passage a short distance from the beach. It is the only river met with on the road from Portalegre to St. Paulo that flows towards the east; the _sumacas_ proceed up only three miles, launches and large canoes navigate freely as far as the first fall. About one hundred and twenty yards above it becomes navigable for the space of three days, by towing, and as many more with the oar, to the next cataract. It rises between the river Negro and the Correntes, (which run to westward.) In its neighbourhood there are many small mountains. The principal confluents which enlarge it are the Rio de Luiz Alves (which comes from the north-west, runs near the mountain of Bahul, seen from the sea at a great distance, and is navigable for small canoes) and the Tajahy Mirim, which runs from the south-west, navigable for canoes about ten leagues. The whole flow through countries of great fertility. Five miles farther to the north is the river Gravata, otherwise Iriri-Guassu, thirty fathoms wide, and navigable for canoes. It is followed by the spacious bay of Itapacoroya, where there is an establishment for whale fishing. Proceeding onwards, the Iriri Mirim and the Camboriu are met with, up which canoes also navigate with the aid of the tide. Near to the latter is the Tajuba, a river of a similar class.
