332 Mr. B. Babington’s Remarks on the Geology 
rock between this village and Antersuntah is greenstone, with what 
seems compact felspar. Whether the latter is all in veins, or whe- 
ther mixing with the greenstone in strata, I cannot tell : from its 
quantity, (for it is lying in abundance on the surface in many parts 
of the road), I should think the latter. From Antersuntah to 
Humpapoor, a distance of seventeen miles, I made no observation, 
as I travelled in the middle of the night. The jungle now becomes 
lower, and the bamboo clumps disappear : it is therefore no longer 
fit shelter for elephants. The hills become lower as you recede 
from the forests, and the soil changes to a red hue, from the black, 
which seems to be decayed vegetable matter mixed with the char- 
coal of parts of the forests that have been burned. 
From Humpapoor to Chiltunhully, the road runs over low wav- 
ing hills, covered in most places with high bushes. The rock is 
exposed above the surface in many places ; in the first part of the 
stage, it is deposited in layers almost perpendicular, and dipping 
towards the south-west. It is impossible to follow the alternations 
of these layers. In one place I observed a layer of quartz, then 
another of greenstone, then one of quartz, then one of lapis ollaris. 
This last is the most abundant rock in this stage, and is sometimes 
more talcose than at others. Some of these layers, both of quartz, 
greenstone, and lapis ollaris, are several feet thick. Between Chel- 
tunhully and Mysore, the ground is strewed every where with 
angular pieces of quartz, greenstone, or lapis ollaris. The quartz is 
sometimes of a red hue. It is remarkable, that although when 
broken with a hammer it has a vitreous fracture, the action of 
the air seems to decompose it angularly ; it assumes also a horny 
appearance. The rock, in situ, at an exposition of it about the 
middle of this stage, seems a stratified mixture of granular quartz
