the H. C.'s Steamer Sesostris and a memorandum forwarded by me to the 

 Hon'ble the President in Council and to Major Phayre with a copy of the 

 paper referred to above, was as follows : — 



Memorandum. 



Coal from Thayet Myo within the British territory in Ava and two miles 

 from the banks of the Irrawaddy brought up by Captain Niblett of 

 IT. C.'s Steamer Sesostris. 



1. In appearance the same as the Ava coal No. I. of the foregoing 

 paper but more compact. 



2. A great deal of shale mixed with it and much of it is top coal (or 

 upper layers only) but there is abundance of the good coal, shewing that 

 the vein has only to be properly mined to furnish good coal. Nothing is 

 said as to its thickness or extent. 



3. It flames well but does not melt. Powder cokes — coke of the coal 

 duller than No. I. but like it burns very slowly. The ash is of a dull 

 muddy red. 



4. Its specific gravity is, 1.36 



Its contents in 100 parts are : — 



Water, 2.50 



Gaseous matters, 30.25 



Carbon, 64.10 



Ash, 3.15 



100.00 



5. Hence it is in fact the same coal as No. I. the differences not being 

 of importance or greater than those which often occur with specimens 

 from the same field or even from the same mines.*

Fossil wood from Ava by Capt. Hill.— Captain Hill of the Bankshall has 

 obliged us with a very fine specimen of fossil wood apparently teak! 



from Ava.

* I regret to learn from Mr. Theobald, Junr. that the vein of this coal which 

 he terms a lignite has been found to diminish suddenly, and that moreover that the 

 formation in which it is found gives no hope of any true coal being discovered in it.
