which, seemingly, a great thickness occurs. All these beds strike 



steadily to east-10°-north, and are either vertical or inclined at a very 



high angle to the south. 



As already mentioned, these rocks are seen faulted against the

exposed between Andhari Bagh, a halting place, 



and the village of Chundpoora, a distance of 5 or 6 miles. The fault; 



bounding the Vindhyans is crossed a little south of Andhari 



Bagh, and, at that place, Bijawur limestone of the usual laminated 



character occurs. A quarter of a mile to the north, there is a 



singular mixture of this rock with a yellow, sandy, and conglomeritic 



breccia. Huge masses of each rock occur surrounded

by the other. The breccia contains rounded 

 masses of a cavernous quartzite and of black hornstone, and a few of 

 ordinary white or coloured quartzite, (occasionally resembling Vindhyan,) 

 as well as angular blocks of quartzite and limestone. The breccia and 

 the limestone are perfectly distinct, and do not pass into each other, yet 

 they are most strangely mixed together. The blocks of limestone con- 

 tained in the breccia are smashed and the cracks filled with the yellow 

 sandstone, which forms the matrix of the breccia, and which seems dis- 

 tinctly to consist of grains of sand.

It is thus clearly due to cleavage and not to bedding. 



It is difiicult to give an adequate idea of this very singular forma- 

 tion. The quartz is partly in contorted and brecciated laminae, partly 

 irregularly dispersed, partly in rounded masses. In some places, the 

 appearance of breeciation appears due to chemical change, which is ex- 

 posed by weathering ; portions of the beds; being harder and more
