MINERALOGICAL DESCRIPTION OF THE ISLAND OF BANKA. 4*21 
bounding the outlets of the rivers there remains a considerable allu¬ 
vial tract: and the district of the mines, commences towards the 
sides of the hills from the boundary of the bay. 
Beginning in the north near Tanjong Muntung we meet the out¬ 
let of the river of Pdnjie flowing into the inner bay, a small branch 
(hut which is considerably dilated by the influx of the tide) takes a 
somewhat northern direction, on this the stockade of Belinyu is built, 
at no great distance from the promontory which runs off from the 
central range and forms the point Tanjong M&ntung. Hence I pro¬ 
ceeded in a northern direction to the district of the mines. 
On leaving the stockade a long extended hill is observed towards 
the central parts of the peninsula, which was pointed out to me as 
Gunung Panjie (or Pantjie) beyond which the highest parts of the 
Gunung Towing are occasionally observable stretching towards the 
south-east. 
The road on leaving the stockade is slightly ascending and the 
country soon becomes waving. About a mile north of the stockade 
I observed the first granite rocks : they soon became numerous on 
both sides of the road, and some of them were of considerable size. 
One in particular attracted my notice. It stood alone, the farm was 
irregularly conical, the top tabular, and the sides, about half way 
down, regularly excavated by the gradual operation of the descend¬ 
ing water after rains. 
Most of these rocks, like those at Mam pang were marked with 
felspar, in large parallelograms and squares. On several parts of the 
road I found loose rounded fragments of Red-Iron-stone, similar to 
those collected in the alluvial districts above mentioned, but I re¬ 
marked none in fixed rocks. 
The district of the mines is situated north of the stockade : they 
have been worked for many successive years and extensive surfaces 
remain exposed. 
The mine at present worked is at Towallam: the pit was regu¬ 
larly oblong. 1 noticed at different sides the following strata. 
In the south
