Coal. 



The following specimens of Coal were collected from the different 

 localities mentioned below : 



7. Coal from the Jamuna falls, highly impregnated with sul- 

 phuret of iron, and liable to spontaneous combustion. The spot from 

 which this specimen was procured is about half a mile above the falls, 

 and five yards from the Jamuna river. The seam is eighteen inches 

 thick. The sample alluded to in the Coal Committee's report for 1845 

 section 39, and said to be " one of the purest and finest Coals hitherto 

 met with anywhere," was a detached piece of Coal picked up by Mr. 

 B. Wood, among the rocks at the falls ; from whence it came has not 

 yet been ascertained. 



8. Coal from the Diphu Nadi, 8 miles above the falls of the 

 Jamuna. The seam is 2 feet 5 inches thick. 



9. Coal picked up in the bed of the Sundra in the Lakhanapura 

 district. Small bits of coal are found scattered over the bed of the 

 river from the mouth of the Jeehing to beyond the first range of 

 Duphla hills. No trace of any seam or accumulation in any part of 

 the river visited. 



10. Coral formation from the bed of the Sundra. 



1 1 . Coal from Jayapura. Jayapura is the only known coal locality 

 to which boats can have free access without risk or obstruction. In the 

 Desairy there are stiff rapids to be encountered below the coal of 

 Borhat. In the Suffry the rapids are more numerous and the naviga- 

 tion more difficult than in the Desairy. In the Dikho there are up- 

 wards of 20 small rapids, between the Santuk Mukha and the coal. 



Lime. 



12. Fragment of a large block of shell Limestone from the falls of 

 the Nambin ; very plentiful. 



13. Fragment of a large block of compact Limestone from the falls 

 of the Nombar. 



14. Fragment of a Limestone boulder from the bed of the Hurrio

15. Limestone boulders from Sunapura. These are found thinly 

 scattered over the numerous quartz and granite boulders in the bed of 

 the Brahmaputra above Noa Dihing Mukha. They appear to be
