VIEW OF THE TIN MINES ON BANKA. 
the western and the northern division of the Island, one passes ex¬ 
tensive surfaces which have been turned up and drained of their 
contents, exhibiting the remains of former mines and aqueducts. 
But, although in the western and in the northern divisions of 
Banka, the most productive situations have been exhausted, or their 
store considerably diminished, yet the annual quantities computed as 
the present produce of the various mines above mentioned (and 
which are exhibited in the table) may with little variation be expect¬ 
ed, as far as my most careful observations have enabled me to judge, 
and after the establishment of the new mines of Mapur, Dshebu, 
Mampang, Pandjie, &c,, and particularly when the great south-east 
division is brought into activity and the mines of Koba, Rangow, 
Kayu-Arro, Tengkiya, Kappu, Selan, Permissang, Banko-kutto &c. 
contribute their proportion, the full quantity stated in the table 
may be expected: this according to my personal calculations and 
enquiries, assisted by the concurrent testimony of well informed per¬ 
sons, must however, be considered as the Maximum to be expected 
from the mines of Banka for the next five years, and probably for a 
longer period, requiring for its production the advantages of a care¬ 
ful administration. 
In the future regulation of the affairs of B6nk£, it will become an 
object of primary policy and interest to investigate experimentally 
those tracts which have in a great measure remained untouched, in 
order, as the beds near the present establishments are exhausted, to 
remove the miners to new situations in those districts which contain 
a larger store of ore. 
To these remarks, I shall only add a few documents which were 
afforded me by the hooks of the Kongsies (or chiefs of the mines) 
as to the annual produce in the following districts for a small num¬ 
ber of successive years:
