Kampong Chisusu, at the S. W. corner of tbat 

 mountain, and to tracé the river Chimangeun- 

 teung upwards to the mouth of the Chiserua, 

 the largöst rill, that pours down frora the pre- 

 cipitous sides of the Gedé. 



The Chimangeunteung rises at the S. E. foot 

 of the Gedé, where it is mountain locked on all 

 sides, except the deep and narrow defile, through 

 which it winds its way, between the Southern 

 base of the Gedé and the Gunung Limbung, an 

 inferior range due South. 



Proceeding upwards, the Chirempag is the first 

 streamlet worth mentioning, that is met with, 

 coming frora the Gedé. From Chisusu to tliis 

 stream the bed of the river is formed mostly of 

 a black schistose rock, which in the first in- 

 stance dips towards the Gedé, or appears some- 

 times to stand on end (as at the small cascade of 

 Masfgit) and latterly dips from or rises towards 

 it. This rock contains a small portion of lime, 

 as it slightly effervesces with nitric-acid. At the 

 spot, where this change of inelination takes place, 

 a stratum of above 12 feet thick of a white, soft, 

 earthy rock protrudes itself between the black 

 schist and occupics both sides of the river; the 

 two rocks are merely in simple contact, without 

 any adhering or welding. On this part of the 

 river no other rocks appear in situ ; but the bed 

 is strewed with a profusion of blocks of tra- 

 chytes, of sedementary rocks, of conglomerates, 

 of immense masses of scorias, of many tons weight; 

 some of which stand 12 or i5 feet high and
