The river Cochim, which originates in the vicinity of the Sanguexuga, runs violently between sides, formed of steep and frightful rocks, which in some places are narrowed to four or five fathoms; in other parts it passes through extensive woods, affording little fruit, but abounding in game, where two sorts of palm trees, in great quantities, are observed, the one called _guacuriz_, the other _bocayuvas_. The principal of twenty-two falls, which interrupt the navigation of this river, are, Mangaval, five leagues below the mouth of the Camapuan; Pedra Branca, near thirty miles below the preceding; and Vare, all requiring double the number of persons to pass; Culapada, Furnas, Canellas d’Andre Alvez, Avanhandavussu, and Avanhandavu Mirim, two miles distant from each other; P. Luiz Antonio, which is very perilous; Jiquitaya; and Cachoeira da Ilha, which is three miles above the confluence of this river with the Tocoary. The principal streams which enlarge the Cochim are the Inferno, (Infernal River,) Sellada, and the Jauru, entering by the right margin; the Furado, Orelha d’Anta, Joam Bicudo, and the Tocoary Mirim, by the left. The latter enters near the embouchure of the Cochim. The Tocoary has its heads near the boundary of Cayaponia, much to the north of Camapuan. When it receives the Cochim, it is already considerable, and near this confluence there is a large fall of its name, where the canoes are relieved of half the cargo, in order to pass it without danger. A little lower there is another small one, denominated Belliago, the last of this river, (the ordinary width of which is here about sixty fathoms,) and also the last of one hundred and thirteen, which navigators encounter from Port Feliz to Cuiaba. The greater part of its course is through campinhas, with little wood, describing continual and short turnings, which give it an appearance to the navigator of his always being enclosed within a lake. It abounds in fish; but its waters are impregnated with a fine sand. Amongst other islands, which it forms, is that of Passaros, (or Birds,) so called on account of the infinite number that breed in it, and with which its trees are always laden: it discharges into the Paraguay, through many channels, which form a great number of islands, generally submerged during the floods of either river. These islands are denominated Pantanos, where, amongst other rare birds, is seen a beautiful one called _anhupocas_. It is the size of the _inhuma_, having also, like it, a horn upon the head, and spurs to the wings; it sings from midnight till day. Wild geese are exceedingly numerous, and for their exclusive sustenance nature here produces a prodigious quantity of wild rice, and of so large a size that no other bird can swallow it. Amongst other remarkable trees, on the margins of this river, the most esteemed is a species of palm tree, thicker round the trunk than the arms of a man can compass; its nuts, which are the size of an ostrich’s
