1848.] Natural Productions of the Angami Naga Hills. 57 



Extract from a Memoir of some of the Natural Productions of the 

 Angami Naga Hills, and other parts of Tipper Assam, by J. W. 

 Masters, Esq. (Communicated by G. A. Bushby, Esq., Secretary 

 to the Government of India.) 



Geological Specimens. 



I saw very little that appeared to me interesting in Geology on the 

 Angami Hills ; scarcely any thing but sandstone, of different degrees 

 of compactness, from soft and friable, to hard. 



The following specimens will show the nature of the rocks met with 

 on the route. 



1. This is a fragment of one of the sandstone pillars in the old 

 fort of Dhimapura. For a description of the pillars, see Captain But- 

 ler's Journal. 



2. Fragment of a sandstone rock from the N. E. side of Samu- 

 jading. A great portion of the hill is composed of this description 

 of rock. 



3. Fragment of a more compact stone found on the top of Samu- 

 jading. Many large blocks of this description are lying loose on the 

 summit of the hill. 



4. Fragment of a tombstone from Samujading. The four show 

 the different kinds of rock that are to be met with at Samujading and 

 along the banks of the Dibbu. No rocks or stones are found in the 

 bed of the Dhanseri, between Gologhat and Dhimapura, except such 

 as flow out of Dibbu Mookh. 



5. Fragment of foliated clay slate, of which the hill of Prephinia is 

 composed. This specimen was procured from a ravine below the vil- 

 lage, where the strata are nearly perpendicular. The rock differs in 

 compactness at different points ; when exposed to the action of the 

 air, it crumbles down with the least touch ; at other points where 

 protected, it is more compact like the specimen, and large flags may be 

 procured. 



6. Fragment of one of the rocks common at Mazamuh. Of this 

 description of rock the terrace walls are formed in the ricefields. 

 These are the only kinds I observed on the Angami hills. I saw no 

 Iron, Salt, Coal or Lime.
