There appear to be (doubtfully) two hsematitie bands in the country 

 Doubtfully two zones hereabouts, one above the carboniferous and 

 of hajmatite. another at the base of the nummulitie series, but 



both are rarely present tog-ether; and where fragments only of one of 

 them are seen, it is difficult to refer them to their proper place ; besides, 

 the vertical distance between the two being- small, one might be taken for 

 the other. 



Speckled sandstones. 



The lavender clays of the speckled sandstone group are of irregular 



thickness, some sections showing them, as above, 



only 50 or even 30 feet thick, while others expose 



them with a depth of very much more than 100 feet. The sandstones 



of the same group are sometimes conglomeratic, sometimes not, and are 



generally much more developed than their representatives in the section
