In a second nullah close to the village the banks were of alluvial clay, 

 they contained very large masses which presented, in one or two instances 

 only, a stratified appearance with a south-east dip, of an angle of 70 

 degrees. The granite contained felspar, mica in crystals, hornblende 

 and quartz. I also found in it veins, with all those ingredients, but in 

 much larger masses, the veins were parallel to the stratification. In a 

 vein composed principally of whitish felspar, I found crystals of corun- 

 dum and tourmaline, the latter of a pale green. 



The vein was parallel to the dip of the strata ; on passing farther 

 on, below the river, the same kind of granite in large masses and 

 without any appearance of stratification occupied the beds and banks. 

 It sometimes contained masses of red and white crystalized felspar 

 the latter containing small specks of mica. I saw at the distance of 

 about 20 miles the peak of Rachapilly. The general direction of the 

 mountains is very difficult to be made out, but that of N. E. and S. W. 

 the nearest. The sand of the river was granitic, being composed of the 

 debris of the granite and small garnets. 



Thatkoor, Saturday, February 26th, 1820. — This place is about 13 

 miles N. W. of the place where Mr. Burr was taken ill last year, and 

 where he terminated his survey of the Godavery ; on our road hither 

 from Merripullee we crossed the river twice, and found in its bed the 

 same kind of granite and granitic sand. We saw two cultivated spots 

 of land in the forest on our way to this place. 



After dinner I went to the Godavery about a mile and a half to the 

 eastward, the bed consisted of granitic sand mixed with calcedony 

 carnelion, agates, jasper, and flinty slate : the banks were about 40 feet 

 in height and composed of the black alluvium, and the bed a mile 

 wide ; on the opposite side of these were lofty hills and one parti- 

 cularly remarkable for its peaked summits. The village of Rachapilly 

 is very near it. 



Sunday, February 27th, 1820. — We rode in the evening to the bank 

 of the Godavery. Having descended it I went about ^ a mile on the 

 sand, until we came to a bed of rocks in the river. We found them 

 to be the slaty granite or gneiss. On our return we picked up the 

 same stones which we observed yesterday. 



Monday, February 28tk, 1820. — We arrived after rather a fatiguing 

 march at Coveeda, which is on the bank of the river. In the evening
