MALLET, VINDHYAN SERIES. 57 



The same evidence of littoral deposition is observable in Gwalior as in 

 Bundelkund. At the entrances to the many gorges which run in west- 

 wards from the face of the escarpments, the conglomerate is 6 or 8 feet 

 thick while half a mile from the mouth it is nearly or quite extinct. 

 The rock is formed of pebbles of the banded jasper and hornstone of 

 the Gwalior series. Under Gwalior Fort where it rests on trap some 

 decomposed pieces of the latter are included. In most places the pebbles 

 are very angular and show no traces of having been waterworn or 

 brought from a distance. Now in Bundelkund they are completely 

 rounded and can be closely identified with no rock in the Bijawurs* or 

 other formations of that part of the country, while they are undistin- 

 guishable from the red jasper of the Gwalior series. Whence they 

 came it is hard to say. The nearest Gwaliors we know of are those of 

 Gwalior itself. 



The Kymore sandstone is very irregularly and thickly stratified, the 

 beds ranging from two to ten feet in thickness. On the Pichour outKer 

 are masses thirty feet thick without joint or bedding. The rock is 

 generally very fine-grained and hard, white or pinkish in color, with 

 minute specks of felspar. The upper surface is very uniform, but the 

 lower, from the uneven floor of deposition, quite the reverse. Hence, 

 (not from subsequent denudation) the total thickness varies greatly, 

 being in some places reduced to a few feet, in others exceeding 300. 



A most interesting section, illustrating at once this and the uncon- 

 formity of the Vindhyans to the Gwaliors, may be seen at the point 

 where the Par and Kymore escarpments meet each other at right angles. 

 The Par is something under aOO feet high, of which the lower 150 is 

 gneiss, capped above by the Par (Gwalior) sandstone ; two hundred yards 

 from the junction of the scarps, the Kymore has about the same elevation 

 and the same amount of gneiss, but the latter suddenly di-ops nearly 

 to a level with the plain, and the hollow thus formed is filled by the
