424 MINER AL0GI CAL DESCRIPTION OF THE ISLAND OF BANKA. 
cias, consisting 1 of coarse siliceous fragments united by a ferruginous- 
cement : to many of these the ore of tin was still found adhering in. 
very minute particles. From Belinyu to Pandjie the country is on 
the whole alluvial, I observed one granite rock projecting from a 
branch of the river : the stones which have been collected by the in¬ 
habitants of Pandjie for various purposes are explanatory of those 
found in the neighbourhood ; they consisted of fragments of granite 
and of Red-Iron-roek. The mines of Pandjie were situated towards 
the hill of that name which has been marked on the map. 
That part of this peninsula which, bounding the bay in the east, 
stretches from the stockade and environs of Belinyu and Pandjie to¬ 
wards the foot of the Gunung Harass is alluvial. The stockade of 
Lumut is situated in it, a considerable distance up the river of that 
name and near the eastern confines of this tract; in proceeding to it 
from the usual landing place the road passes several elevations which 
here bound the alluvial plain. These consist of Red-Iron-stone in 
separate rocks and in large veins covering extensive surfaces. Loose 
fragments are also dispersed on the road. Those rocks which I ex¬ 
amined more minutely and from which I collected specimens, were 
more similar to those of Jehus and Kl&bbet than those found at the 
mines of Towallam just mentioned. 
They are mostly cellular and the fracture is partly ochreous and 
partly metallic: the separate particles of some of them are very pon¬ 
derous. 
These hills formerly contained strata of ore which lias succes¬ 
sively been extracted: on approaching the stockade one passes the 
remains of many of the former mines. Here the surface is covered 
with mixed stones ; fragments of granite, breccia and coarse sand, 
similar to those found at the aqueducts, are strewed on the sides of 
the road in every direction. From the stockade of Lumut the dis¬ 
trict of the mines stretches northward inclining to the west until it 
meets that of Pandjie and Belinyu. 
I commenced the examination of the mines of Lumut about half a 
mile to the north of the stockade at one of the small mines which 
had lately been relinquished. The process had been carried on as
