Thursday, 4 th February, 1819. — I saw also near the village of 

 Bachapilly some singular veins of granite rising through a greenstone 

 or syenitic greenstone, very similar to what I had before observed on 

 the banks of the Manjira : the veins having resisted decomposition much 

 better than the containing rock remained projecting two feet in some 

 instances : it is remarkable that a shift of the veins had taken place : 

 the granite vein was sometimes white and sometimes red like that at 

 the Manjira, the course of what we could discern of this formation, 

 which lay in a field formerly in cultivation and over which the 

 jungle was spreading, was east by south. Visited the Bears rocks, a 

 granitic elevation of thirty feet, distant east by south from the sta- 

 tion about 400 yards. Its base consists of a large grain containing red 

 felspar, white compact ditto, and hornblende, forming altogether a beau- 

 tiful stone ; through this mass, a vein of syenitic greenstone differing in 

 width from three feet to a few inches, runs for about fifty feet ; this is 

 again crossed by veins of a finer granite nearly resembling that higher 

 up, which is in large blocks apparently placed without order, but an eye 

 accustomed to these rocky elevations, almost peculiar to this country, 

 discerns in these masses the remains of a concentric coat of granite. 

 The remains of strata filled with these granitic veins are very common 

 between. 



Friday, 5th February, 1819. — On our road through the plain the 

 same kind of granite to which we had been so long accustomed was 

 frequently seen in irregular masses, two miles from Bachapilly we 

 crossed a small nullah running in the direction of the Manjira. Imme- 

 diately before entering Polelum a large deposit of quartz rock running 

 E. and "W. about half a mile, resting on granite. It was of the same 

 description as that at Joggypett : our road then lay through a plain of 

 black cotton soil, when after a tedious journey through a thick jungle 

 in which nothing was to be seen except masses of granite, and now and 

 then lumps of greenstone, we began to ascend a hill composed of green- 

 stone, having the same characteristics as that of Tandmanoor, containing 

 foliated zeolite in abundance and calcedony lying loose in the ravines, 

 and on its surface high kusa grass (Poa cynosuroides) . 



Sunday, 7th February, 1819. — I quitted the hill with Everest early 

 to go to Kowlass, we descended one of the ravines so common on these 

 hills and soon came to the usual kind of granite, but could not observe
