170 BROWN & HERON: GEOLOGY AND ORE DEPOSITS OF TAVOY. 



The occurrence of wolfram sand is noted in the Loundoungin 

 river. 



4. Kahan, a small hill near the Zedavoun pagoda on the right 

 bank of the Tenasserim, 11 miles from Mergui, where a 

 vein, three feet wide, was seen in white sandstone.

Mergui." Journ. Asiatic Soc. Bengal, Vol. XI, pp. 839—

Records the shipment of specimens of Mergui tin ores to 

 England. 



1843. G. R. Tremenheere. " Report of a Visit to the Pakchun 



river, and of some Tin localities in the southern portion 

 of the Tenasserim Provinces." Journ. Asiatic Soc, 

 Bengal, Vol. XII, pp. 523—534.

This paper summarizes Heifer's and Tremenheere's observa- 

 tions. It states that Heifer discovered tin ore near 

 Loadut, about 110 miles north-north-east of Maul- 

 main, and that in 1840 he reported the country to the 

 north of the Pakchan river to contain the richest 

 stanniferous deposits within the Tenasserim province. 



Tremenheere's opinion is that the tin of the Tenasserim pro- 

 vinces occurs chiefly in the beds and banks of those 

 rivers which issue from the primitive mountains.
