A few leagues below the passage to Goyaz there is a fall in the Mugy, which arrests the further progress of fish, and, in consequence, at a certain period annually a numerous band of fishermen assemble here, with _cargas_ (horse loads) of salt, which enables them to furnish the more distant places, from the abundant draughts with which they are here supplied. Navigators compute two hundred and fifty miles from Port Feliz to the mouth of the Pipira, and as many more from this point to the confluence of the Tiete with the Paranna. The imperfect methods of overcoming the natural difficulties which are presented, require twenty-six days to accomplish this voyage of five hundred miles. Its course is very winding; twenty-five miles are reckoned in a direct line from Port Feliz to the mouth of the Capibary, and nearly sixty by the river. It is fifty miles from the mouth of the Jocoaquatu to that of the Pirassicaba, and only twenty in a straight line. The bed is principally stony, with a great number of islands and falls, the most important of those precipitations are denominated Avare-Manduava, Itaguassava, Pirapora, Bauru, Barery-Mirim, Barery-Guassu, Escaramuca, Utupanema, Funil-Grande, (the Large Funnel,) Guacurytuvussu, Aracanga-Mirim, Aracangavussu, Utupeva, and Utupiru. The labour requisite to pass these falls with canoes is very great. There are above sixty other places attended with difficulty, and half that number with considerable danger, but which, notwithstanding, are passed without unloading the canoes. The banks of this river are almost universally covered with superb timber. Amongst other fruit trees are the _jabuticaba_, quince, _cipota_, _jatahi_, _nhandipapo_, and _uvacupari_. From the bark of some trees the aborigines and the certanistas construct canoes for the purposes of navigation; and the resin extracted from them the Indians use for lights, and for ornaments for their ears and lips. Among other species of fish it affords the _doirados_, _saupes_, _pacus_, _piracanjuvas_, _surubins_, _piracambucus_, _jahus_, and _piraquaxiaras_, some of which weigh two arrobas, or sixty-four pounds. It would be of incalculable advantage to the internal provinces of Brazil if the government would adopt some effectual mode of diminishing the numerous natural difficulties the Tiete presents to navigation. The voyage is also prolonged in consequence of the fogs, which almost every morning deter the canoes from departure till eight o’clock, when these mists usually disappear.
