much covered up by debris and jungle^ while the impossibility of ascend- 

 ing and crossing the ridge in a direct line, owing to its precipitous nature 

 towards the top, exposes the observations to the possibility of the same 

 bed having been reckoned more than once. 



The following approximately accurate list shows the observed se- 

 quence of the beds from below upwards : — (Fig. 9.)

by beds of Quartzo-felspathic gneiss (some compact) . 



7. Iron bed (No. 3).

9. Iron bed (No. 4) see below. 



10. Quartzo-hornblendic beds, full of large garnets, and of great 

 thickness, forming the summit ridge. 

 The concentric appearance of the various beds as seen in plan is due 

 to their forming part of an elliptical basin, owing its origin to a modified 

 synclinal fold. The north side of this basin has been almost 

 entirely removed by the gigantic denuding forces to which this part of 

 the comitry has been subjected at some long by-gone periods,
