MOUNTAINS.--This province has no very considerable mountains, excepting the cordillera called the General Serra, which runs from the north, near the sea, and in the parallel of 29° 30′ turns to the west, and then north-west with some windings, breaking in many parts to afford a passage to various rivers, amongst others, the Paranna. The mountain of St. Martinho, or Monte Grande, is a portion of that serra, where it divides this province from that of Uruguay. Monte Vidio, or Video, situated on the west side of the bay to which it gives the name, is pleasing to the view, and high only in the vicinity of the sea. The Castilhos Grandes is a hill near to the point of the same name, and crowned with stones, that appear like towers. [Illustration: _On Stone by C. Shoosmith from a Sketch by Jas.

The Serra dos Tappes, which is of very small elevation, runs parallel with the lake of Patos at a distance of from four to seven leagues, being fifteen leagues long from north to south, and five broad. That of Herval is further to the north, behind the Tappes. The extensive chains of small hills, without trees, and forming pasturage for flocks of cattle, are called _cochilhas_. The before-mentioned Pao d’Assucar is at the southern extremity of the chain called the Great Cochilha, which extends itself to the north as far as the source of the river Arica. In many parts, its elevation is imperceptible, appearing like a plain, and from both sides other mountains branch off, as do some rivers which have their origin in it. The hills ranging to the west of it are not well known; the largest on the east are the Herval, the Piratinim, approximating the rivers of the same names, and the Babiragua, in the vicinity of the Camacuan. The highest points of the hills and cochilhas, and destitute of vegetation, are called _serros_, their summits serving on occasions of war for watchtowers, which are numerous, and some of them are seen from others at a distance of twenty leagues.
