 Sie, 



On the 7th instant I had the pleasure to send you by dak No. 3 speci- 

 men of copper ore from Pushak in the Darjeeling territory. It was taken 

 from a different place from No. 2, that is to say, it was from the same 

 spur of the Pushak hill but 2 or 300 feet lower down, and close to a 

 stream of water. 



2. I have now the pleasure to send you a specimen No. 4, which I 

 believe to be also a copper ore ; it comes however from a different locali- 

 ty, but still in the neighbourhood of Pushak, and in the British territory. 

 It was found at " Mungwalt" a mountain spur to the south of Pushak. 

 "When fresh from the earth it was of an apple-green colour, portions of 

 it are friable, with a golden tinge, and the crystallized structure of it is 

 quite apparent. It was found about four feet below the surface. The 

 top soil was red and yellow which attracted the attention of the search- 

 ing party, and induced them to dig. I shall be glad to hear if it is a 

 copper ore, and if you require more of it for examination, I shall send it 

 to you. Call it the Mungwah specimen in alluding to it. 



3. I have about 4 lbs. of metallic copper which has been obtained from 

 the ore sent to you as No. 3, the ore was not weighed, but it is reckoned 

 that about 801bs. was used to obtain the above quantity of metal. This is 

 a poor return, but the Nepalese smelters who are with me say that the 

 poverty of a copper ore on the surface, is, in the Nepal mines no guide 

 at all to the quality of the interior veins. I have got now about three 

 maunds of the ore, which I purpose having weighed and carefully reduced,
