30th May, 1819. — Here commences my expedition with Everest 

 during the rainy season. 



4th June, 1819. — To the left of the road before reaching Hyderabad 

 I observed a deposition or bed of quartz rock which I ascended, but 

 was not able to discern its termination on either side, its direction was 

 due north and south. The granite in the bed of the river Mussy was 

 reddish inclining to grey. The evening closed too soon on me to allow 

 of any observations before reaching the camp. 



5th June, 1819. — I arose with the sun and ascended the hill which 

 rises about 100 feet above our encampment. I observed a vein of 

 the greenstone precisely resembling that of Golconda and Secunder- 

 abad, its direction E. and W. as usual. The granite is of a greyish 

 colour, containing large crystallized masses of felspar of a similar 

 colour to that observed at Ardinghy. 



I no longer observe loggan stones, the granite is more compact and 

 less liable to decomposition. About a mile from the station in a westerly 

 direction, I observed a long vein or deposition of quartz rock running 

 north and south, probably a continuation of that observed yesterday, 

 also on the ground numerous small concretions of carbonate of lime. 



6th June, 1819. — I quitted the camp early for Chitterghat. The 

 granite was generally of the reddish grey colour, with loggan stones, 

 but fewer than I have observed in other parts. 



7th June, 1819. — We arrived at Ballapooram, distant 8 miles from 

 our last station, the vein of greenstone was observed to our right run- 

 ning nearly east and west. At one period, it crossed our path and we 

 lost sight of it ; soon after at this place we had heavy rain during four 

 hours. 



Sth June, 1819. — We passed through Hyattnuggur and saw a trap 

 vein to the right of our road which accompanied us for a considerable 

 distance : it re-appeared at Seringhur, on the side of a granite hill. 

 9th June, 1819. — The granite between Seringhur and Mulkapoor
