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 Chushmea, 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

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 wood-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 14 inch bedded. 
From the same locality as No. 1.

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 appearancé, 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,
