 is especially attracted by the nature of the country 

 through which it flows. The whole system of the 

 rivers, which it and its collateral, the Paranahyba, 

 receive during the whole of their extensive course, 

 descends from mountains which are distinguished, 

 above many others, as much by their height and 

 extent, as by their especially belonging to that

 from that of the Rio Grande. All these mountains, 

 which are chiefly composed of quartzy mica-slate, 

 contain on both their declivities the richest stores of 

 that metal. They form the principal stem of all the 

 Brazilian mountains of the interior, and in them
