the Godavery and part of the Vindhiya range which runs N. W. and 

 S. E. 



Monday, 24th September, 1819. — The holes so frequently interrupt- 

 ing my night march appeared to communicate with gullies under the 

 surface of the alluvial soil and running on the sandstone beneath. 



Tuesday, 25th September, 1819. — The tabular mountain of which I 

 have spoken on the 19th is near the place where the clay slate first 

 makes its appearance in coming from the eastward, in stratified masses 

 little elevated above the surface, a S. E. dip and an angle of about 40°. 

 The change in the soil was very perceptible, the traces of travellers 

 dried by the sun showing adhesiveness and clayey composition. The 

 hill above alluded to had its upper half, at least, composed of sand- 

 stone. The access was too difficult and my time too short ; at a distance 

 the precipitous hills and rocky narrow vallies commence. 



The clay slate is generally very much indurated, contains large and 

 small veins of quartz ; I observed also quartz rock or sandstone about 

 its centre. The explanation that first presented itself of the pheno- 

 mena which were here seen on so grand a scale was, that all the clay 

 slate had been originally covered with sandstone, and that a general 

 and partial subsidence of strata had taken place, producing on the 

 one hand the dip to the S. E. and on the other the central isolated 

 masses with precipitous sides and covered by the sandstone which 

 had remained in its original state. 



Tuesday, 28th September, 1819. — I ascended the hill of Punchbun- 

 doll twice during my stay at Commerarun. The road to it lay through 

 a plain of six miles intersected by nullahs, containing most gener- 

 ally angular pieces of sandstone and clay slate and very little alluvial 

 mud. The ascent to the hills was about 4 miles in length and lay over 

 quartz rock or sandstone and slate. In the ravines quartz or sandstone 

 alone was to be seen lying in the strata, but horizontal. The principal 

 ravine I passed had apparently been formed by a slip of the strata, one 

 side being perpendicular and the other a gentle slope. 



Komarum, 30^ September, 1819. — During this day's journey I no 

 where observed the iron clay ; the greater part of the road lay over 

 alluvial clay. At times indurated sandstone or quartz and clay slate 

 of the kind described at Allatoor, small pieces very much decom- 

 posed and passing into clay.
