especially when just struck off, had a considerable

 is either quite compact or traversed by veins of red

 contact with a yellow quartzy sandstone, with an 

 argillaceous cement ; at least, the latter is seen in 

 several places at the foot of the mountain, as well 

 as in Ypanema itself. A dirty lavender-blue primi-

 runs from east to west, lies on the top of the 

 mountain, here and there, over the iron. Upon 

 the Morro de Araasojava, and probably in veins 

 of the magnetic iron-stone, there is a porous quartz- 

 stone, of a light brown colour, the cavities in which 

 are covered with a bluish white calcedony, with a

 uncommonly rich in the most various kinds of wood. 

 In the company of a farmer of the neighbourhood, 

 we collected, in one day, a hundred and twenty

 (TArruda, Coracdo do Negro, both chiefly used for fine fur- 

 niture on account of their red grain ; Jacaranda-tun, an 

 excellent kind of mahogany ; Masaranduvay Cabiuna, Perova^ 

 Paraunay Jequetivcif Cedro, &c.
