 not in lodes, but disseminated through the slates and schists. F. D.

 A seam 3 feet thick has been found, containing 37*8 p. c. of carbon 

 and 31-6 p. c. of ash. It might be worth mining on a small scale.

The outermost range of hills closely resembles the Sivaliks of the 

 N.W. Himalayas, and the beds they are composed of are probably equi- 

 valents of the Sivalik formation, while further in the Nahun beds are 

 found. Of the former, a thickness of 10,000 feet is exhibited ; but 

 this, the author observes, does not imply vertical sequence; of the 

 latter, also, a great thickness is seen. North of these Tertiary rocks 

 are schists, quartzite, and limestone, some of which may be the equi- 

 valents of the Krol group of the Simla district. On the N.N.E. side of 

 the Nepal vaUey is gneiss. This vaUey has 125 square miles of either 

 alluvial or lacustrine land. It is a rock-basin ; but the author does not 

 attribute its form to glacial action ; it is not in the course of any main 

 drainage Hue ; its production is referred rather to local yielding after 

 denudation. Some erratics are noticed at an elevation of only 1500 

 feet; the author is in doubt whether to put them down to glacial 

 action. F. D.

The ground belongs to the Yindhyan plateau, which is cut into by 

 the wide and deep valleys of rivers draining to the Jamna, and is 

 bounded on the S. by the Vindhyan range. A considerable area is 

 occupied by basaltic trap, connected with that of the Deccan plateau ; 

 in age it is between Nummulitic and Cretaceous. Beneath it is lime- 

 stone and sandstone, called Lameta (? middle Cretaceous). Then occurs 

 a great gap between these and the Vindhyan rocks, which are the next 

 oldest in the region. This formation is divided into Bhanrer (sand- 

 stone, shale, and limestone), Riwa (sandstone and shale), Kaimur 

 (sandstone, conglomerate, and shale). The age of these is undeter- 

 mined. i^Tear Gwalior the Vindhyan s rest unconformably on rocks to 

 which the name "Gwalior series" has been given. The territories 

 include also a small area of gneiss rock. F. 1).
