The valley of the Ooree river about Koja Kooa is^ for many miles, 



occupied by metamorphic rocks, which extend also

 beds in Ooree valley, near far up the side valleys. Between the several de-

pressions in which the cretaceous beds and meta- 

 morphic rocks are exposed, great flats of trap extend : these are, however, 

 mere caps, cut through by every little ravine. The surface of the meta- 

 morphic rocks upon which the cretaceous beds were originally deposited is 

 also very uneven. Erom all these circumstances there results extreme 

 irregularity in the outline of the various formations. This has not been 

 shown in detail on the map, and indeed it could only have been correctly 

 delineated upon a far more detailed and accurate representation of the 

 topography of the country than that available for the purpose, nor could 

 it be represented at all upon a map on so small a scale. 



Along the north of the metamorphic area in the Ooree valley, and 

 also further west, there is no such continuous representation of the cre- 

 taceous beds as is seen to the south ; indeed their occurrence is rare. This 

 appears to be partly due to their having originally been very thin or 

 wanting in places, partly to subsequent denudation. Thus at one spot 



about a mile west from Tanda, and just south of
