204 Dr. Voyseys Private Journal [No. 3. 



It is worthy of remark that this river after we crossed it at Begum- 

 pett, takes a considerable turn to the N. and that its bed no longer 

 contains calcedonies there found in it. The mud however is the same, 

 and appears to be that arising from the decomposition of the trap rock 

 of Tadmanoor and elsewhere. After passing some elevated minor 

 granitic hills, we pitched our tents on the borders of a lake at the foot 

 of the station Suldapoorum. 



Wednesday , 20 th January, 1819. — The mixture of granite and 

 syenitic granite extends to this place, as I observed masses of the 

 syenitic granite imbedded in the former near my door, it reminds me of 

 the same appearance at Teeperty, near Neelgondah ; as I have speci- 

 mens, I shall have an opportunity of comparing them. 



Thursday, 2\st January, 1819. — About halfway up, the blocks 

 of granite disappeared, and the path presented the decomposing trap 

 rock of nearly the same nature with that of Tadmanoor hill, its 

 decomposition forms the same rich soil as on that hill ; I found 

 amongst it specimens of a substance intermediate between heliotrope 

 and hornstone. From the top I counted 33 lakes and should have 

 counted more had the horizon been clear, the hill is not above two 

 hundred feet in height, my barometer fell -^ inch. The neigh- 

 bouring mountains were slightly elevated above us and their direc- 

 tion and form nearly that of the one we were on, N. and S. and 

 round backed, with two or three slightly conical and more elevated sum- 

 mits in the range ; in one instance a range of low hills appeared to 

 cross diagonally, indeed the direction of all was very indistinct and 

 most commonly curvilinear. 



Friday, 22nd January, 1819. — For several miles after quitting 

 Suldapoorum, I passed through a beautiful forest of Teak, Mango, 

 Ficus indica, Tamarind, and other fine trees and shrubs mostly 

 leguminous ; the soil was partly granite and partly decomposing 

 greenstone, but wherever rocks were visible they were invariably grani- 

 tic. At a small village situated on an immense divided mass of granite 

 a trap vein (primitive greenstone) crossed my road, running east by 

 south ; another about two miles farther became visible, of larger dimen- 

 sions and was lost in the jungle, in a short time we were surrounded 

 by granitic rocks with the same features which distinguish those of 

 Hydrabad ; huge masses with a concentric lamellar structure, loggan 

 stones, tors, &c, but with a large quantity of detritus at the feet.
