*733 MINERAL PRODUCTIONS OF THE TENASSERIM PROVINCES. 
of India and China, which, whatever may be the flotations in 
value in the home market; serve to maintain a regulated and steady 
value in the Straits markets, which not even an amount of produc¬ 
tion to double the extent of the present extensive one, would 
materially affect. 
With the foregoing exposition of this sterling description of 
mineral wealth which these provinces so abundantly possess, it is 
to be hoped that the period is not far distant when the attention of 
capitalists will be directed to the subject, and that in the prosecution 
of an enterprise in a locality enjoying an equable and salubrious 
climate, a rich and inexhaustible soil, and blessed with the perennial 
verdure of the tropics, a new branch of commercial resource will 
be created, whieh will claim for this beautiful portion of the British 
territory, a consideration its rising importance merits. 
Manganese. 
The ore of this mineral as a grey oxide is found distributed in the 
secondary formations pierced by the tributaries of the Thoung- 
yeen and Gyne rivers, it also occurs ,on the great Tenasserim river 
in the vicinity of the coal mine, and is noticed by Captain Tre- 
menhere as follows. 
« The best ore (Manganese) is found on the Thuggoo river and 
on the bank of the Great Tenasserim. It occurs in the form 
of a black oxide, and is the manganese of commerce : It is in 
large demand in Europe in the preparation of bleaching compound, 
and when pure is valuable to the manufacturer of glass : quality a

There is sufficient at the locations referred to, to indicate extensive 
deposits which can be collected by removing the soil lying above 
it and near the spot in which it lies exposed.” 
From the extensive use of this mineral in the arts, and the facili¬ 
ties of extracting it from the beds described, it may be presumed 
that a shipment of it to the London market would affoid encouiage- 
ment for more extended operations thci ein ; the only chai gcs in¬ 
cident to its being placed on board ship being those of labor in ex- 
tracting, which, from its position near the surface would be com¬ 
paratively trifling, and the subsequent water carnage to a depot 
from where it could be shipped. This appears to be well worth the 
attention of the British merchant, who in the event of a successful 
result, would have the honor of adding this article to the staple 
returns for imported merchandize. 
Antimony. 
The sulphuret ore of this mineral appears to be pretty general 
throughout the provinces; accompanying the sandstone of the 
older formation, in which it is found forming veins ol vanous
