44 Notes to accompany a Geological map. £No. 1, 



Examination of the Lignites. 



The following samples were given to me by Lieut. Lane, District 

 Superintendent of Police, Bunnoo. 



No. 1. — From a seam newly discovered near Chushniea, north of 

 Moolakhel, 8 miles from the Indus. 



Best quality, with a resinous fracture and lustre ; jet black in colour ; 

 Sp. gravity 1.25. 



Volatile inflammable substances, . . . .50 



Fixed carbon, ........ 35 



Ash, . 15 



100 



There is a partial caking when the lignite is burnt in a close vessel. 

 The ash is a mixture of a reddish earthy powder, of hardened pieces 

 of slaty shale (holding a little unreduced lignite) and of a fluffy 

 white ash like woocl-ash. The red earth and the pieces of shale are 

 mechanical impurities. The white fluffy ash is the proper ash of the 

 lignite. 



No. 2. — Best quality, as No. 1. Apparently a very little yellowish 

 white clay adhering to the lignite which is 1J inch bedded. 



From the same locality as No. 1. 



Volatile inflammable substances, . « . „ .50 

 Fixed carbon, ........ 40 



Ash, .10 



100 



Same remarks as for No. 1. 



No. 3. — Middling quality, the usual quality of the bed. The 

 lignite is in thin plates like leaf bed ; each thin plate is sometimes 

 resinous in appearance, but more frequently has the appearance and 

 lustre of charcoal. It contains a considerable amount of yellow clay 

 between the plates. It crepitates in water like salt deflagrating on 

 fire. Its Sp. gravity is 1.28.
