 Two walls on the Runn, forming a semicircle, but sloping outwards. 



In one place these walls form a semicircle about 500 yards in diameter^ 

 both walls sloping outwards. That the walls have been uplifted into their 

 present form is quite evident^ first, from the stones being- all on end, that is, with 

 the grain in the direction of their present position, and peeling off in scales 

 down the face of the wall ; and secondly, from my having met with the same 

 phenomena on a smaller scale, in other parts of the country, where the slabs 

 of rock are at all angles, and even, as those before mentioned, turned over. It 

 should be noticed, also, that the borders of the Runn, near these walls, are 

 composed of friable beds of the laminated series, covered with thick tabular 

 masses of hard sandstone, precisely similar to those forming the walls. 



Had they been uplifted during the permanent prevalence of the waters, the 

 sloping talus of earth and fragments of rock, with which they are all backed, 

 must have been washed away. It should be stated, that these examples are 

 situated on ground now almost recovered from a state of Runn ; some parts 

 having been sufficiently augmented by means of the sandy alluvium, washed 

 down from the neighbouring hills to support vegetation ; whereas the iso- 

 lated rockSj several of which rise out of that part of the Runn, and are still 

 subjected to inundation, have no detritus or talus, but present smooth walls 

 of perpendicular rocks. I could never perceive any water-marks on them, 

 nor any remains of marine testacea, which might occur, had the sea ever 

 washed the present level of their foot. It is probable that their origina 

 base lines have become obliterated by the sediment which must have accumu- 

 lated round them in course of time, and which forms the existing surface. 



A very good example of a similar wall occurs in the centre of the province, 

 near the village of Rampoora; it is a ridge of coarse sandstone about 300 

 yards in length, and from 10 to 15 feet in height, the stones being evidently 

 placed edgeways, and in so regular a manner as to resemble precisely an ar- 

 tificial wall. It rises from a base of the same sandstone, and on one side it
