JULY— SEPT, 1857.] at Kola on the Godavery. 261 
occasionally a little to the S. of W. and sometimes to the N. of W., 
the direction of the river being N. W., at this part we are travers- 
ing in our course up the channel from the lower to the higher of 
the stratified rocks. 
We continue in this upward direction in the series until we reach 
Yeytoor, where occur tjie uppermost beds I was able to exa- 
mine. These consistof veryuniformly stratifiedlimestones 6inchesto 
18 inches thick, the layers parted by soft clays and fibrous limestone, 
of these there were only visible above the water in the river 12 or 
15 feet in thickness, above these occur beds of deep red marls, and 
variegated clays* 'their inclination is very small being about 5^ 
only, and to the W! S. W. 
From Yeytoor to Taicologodeen the course of the river leads 
us downwards, in the series again we pass over red and pink clays, 
and lastly to a white sandstone, at the latter place. Immediately 
after Taicologodeen we came into the metamorphic rocks forming 
the Enchampilly barrier. 
After passing over about 12 miles of these, there occur near the 
village of Punkenna beds of limestone, very similar in external 
appearance to those seen at Yeytoor, they are in thickness from 
12 to 18 inches and parted by thin seams of clay and fibrous lime- 
stone, their dip is to the N. E. about 5° to 10°, — at low states of 
the water in the river, they are seen on both banks, a considerable 
extent in superficial area being on the left, but owing to their low 
inclination a small amount only in thickness can be observed. 
From this point to Nuggrum, we have frequent opportunities to 
observe the beds on both banks of the river, the general dip of 
them is N. E., the course of the river being N. "W. we traverse 
along the strike of these beds somewhat however to the deep ; we 
reach the lowermost beds on the right bank opposite Nuggrum ; 
they consist almost entirely, of ferruginous sandstone, of various 
degree of coarseness and traversed by numerous veins o*f a harder 
description of the same material. 
Between Punkenna and a point in the river opposite Mahadeo- 
pore, we get at very low states of the water in the river a small
