MINERAL PRODUCTIONS OP THE TENASSERIM PROVINCES. 726 
Junk Ceylon with the object of collecting tin, which then as now in 
the latter place, composed the principal medium of trade and 
currency. The wars of the Burmese and Siamese, and the constant 
forays of the latter, carrying off the population into slavery, have 
tended to restrict the production of the metal from this locality to 
an amount insignificant in the extreme, when compared with the 
capabilities it possesses; and it will be seen from the following 
remarks, that not only do these provinces abound in deposits 
which, if worked, would surpass the production of any other part 
of the known world, but further, that the richness both as regards 
extent and depth of the beds and purity of the ore, exceeds that of 
any other tin producing country in the east. 
The known localities of the stream tin are as follows 
1 . The mines of Mal^wan and the tributaries of the Pakchan 
river. 
2. On the Bok-pyn river to the northward of the above. 
3. In the upper branches of the Lenya river. 
4. On the Thengdau river in the vicinity of the coal mine on the 
Great Tenasserim. 
5. At Thaban-liek on the little Tenasserim river. 
6 . At Kamoungtan, Engdau and Thapy-an in the same locality* 
hut not so accessible as Thaban-liek. 
7. At Yamon about 20 miles from Mergui, on the south side 
of the Great Tenasserim river, of an inferior quality, being mixed 
with wolfram sand or tungstate of iron. 
8 . In the Toung Byouk valley, a little to the southward of Tavoy 
river. 
9. At the head waters of the Great Tenasserim to the eastwatd 
of Tavoy—noticed by both Dr Heifer and the Revd. Mr Mason, 
10. In the upper courses of the streams which flow into the Bay 
of Henzai (a beautiful spot on the coast situated between Tavoy 
and Ye) the ore obtained from this locality contains grains of gold 
and garnets. 
Mine Tin 
11. Is found in the hill of Kalian near Mergui in a decomposed 
granite matrix passing through the sand stone. This hill is in facta 
repository of mineral wealth which not even the richest (Tin) mines 
of Cornwall can excel, as will be seen from the remarks which 
follow. 
Up to the point of Henzai in lat. 14* 50’ N. the stanniferous 
formation appears to exist uninterruptedly from the Pak-chan; 
about this position however the primary sandstone range inter¬ 
venes and produces an entire change in the character of the streams 
and their deposits, but it may reasonably be expected that the valley 
formed on the coast line by the sandstone, and to the eastward by 
' the granite primary schists of the peninsula range, will prove on 
examination to possess tin deposits equally rich with those described.
