ia operation sufficient to account for a large amount of meteoric 

 denudation.* 



If anything were wanting to prove the extent of this erosive action, 

 the rain-worn surfaces of the limestone plateaux, the numerous little 

 patches of level ground, remains of former flats among the Kudderas, 

 the pinnacles and profound ravines along the escarpments, and the mass 

 of detritus brought down by torrents, would amply establish its existence 

 and its power. To this agency alone, operating upon suitable materials, 

 can I attribute the removal of the once overlying tertiary sandstones.

 Government Oaxette for three years : —

From this it would appear that the general average rainfall of the comitry in which the 

 Salt Range is situated is equal to about 16 inches. Mr. Login, in a paper which has recently 

 appeared in Vol. XXVIII, Journal of the Geological Society of London, p. 186, thinks that the 

 rainfall of the Punjslb is the same now as it was two thousand years ago, but more restricted 

 to the mountains. Dr. Verchere, at section 96 of his paper previously referred to, argues 

 that at the beginning of the miocene period in these regions the rainfall was excessive, 

 resembhng that of Patagonia.
