 on the land belonging to a large fazenda on the 

 road, built in the style of a cloister. In general, 

 the whole Serra de Antonio Pereira agrees in its 

 component parts, and the nature of its strata with

 slate containing ironglance, and a far-spread man-

Among the plants which grow on this moun-
