1842.1 Second Report on the Tin of Mergui. 841 



p. S. — If it should be thought advisable to send a copy of the accom- 

 panying report to Professor Royle, it would afford better information 

 than I was able to give in my hurried communication of May last, 

 alluded to in the 2d para, of this letter.

Received from the Military Board by order of Government, for the 

 Museum of Economic Geology of India. 



Having in the 16th and 17th paragraphs of my first Report of the 

 31st August last directed attention to a rich deposit of Tin, existing 

 at Kalian on the Tenasserim river, a few miles from Mergui, I have 

 now to add the following information which has been since collected 

 respecting this locality. Experimental operations have been in pro- 

 gress there since the end of April last, by order of the Commissioner, 

 and under direction of Mr. Corbin, Assistant to the Commissioner at 

 Mergui, with a view to ascertain the value of the spot for mining 

 purposes, and I am happy to have it in my power to state, that these 

 have been attended with complete success. More than eight hundred 

 weight (8 cwt.) of clean ore of the pure peroxide of tin, ready for 

 smelting has been collected by a gang of convicts, and was despatched 

 from Mergui on the 18th July; this has been received at Moulmain, 

 together with some bulky specimens from the same hill of macled 

 crystals of tin or quartz, which in weight and in size of the crystals, 

 surpass any thing I have seen in Cornwall or in Cabinets elsewhere. 



2. In the early part of May, I proceeded to Mergui on the Steamer 

 Ganges, and on the 10th of that month, visited Kahan in company 

 with Mr. Blundell and Mr. Corbin. The survey of the hill, plan of 

 which is forwarded herewith, was made on the following day. It will 

 be seen therein, and by the portion of map on the same sheet copied 

 from Capt. Lloyd's Survey of the Coast, that Kahan is one of several 

 small detached hills upon what may be termed the Island of Mergui, 

 formed by two branches of the Tenasserim, one of which debouches a 

 few miles to the north of Mergui, and the other to the south, which 

 is divided near the sea into numerous channels by flat mangrove 

 ground. The general surface of the island itself is of level alluvial
