Wednesday, 30th March, 1819. — I visited the small hill I have 

 before mentioned, and found reason to suppose it artificial. The black 

 soil was in some places intermixed with the trap clay, and in others 

 was in indistinct zones, all with N. or N. by W. direction. 



Thursday, 3\st March, 1819. — We descended from the iron clay 

 during the night, and in the morning found ourselves on the black soil 

 in a level plain. I found considerable quantities of carbonate of lime 

 intermixed with the wacke which is here found in the same nodular 

 masses with a hard kernel which I have before noticed at Banktapoo. 

 The soil contained a large quantity of carbonate of lime effervescing 

 considerably with acids. 



Friday, 1st April, 1819. — I crossed three nullas on my road to 

 Sedashewpett, during a journey in the dark, all running eastward along 

 a ridge of gently undulating and sightly elevated land, as seen to the 

 eastward as day broke, apparently a continuation of the Tandmanoo 

 range, and taking the same direction. At day break I fell in with 

 large masses of granite lying in the black soil, and in a ravine saw 

 plainly that it formed the substratum covered with the cotton soil, 

 although not in all parts, the soil being granite in the highest part. 

 To the westward are seen the flat tops of the trap hills and the pecu- 

 liar abrupt termination of the iron clay of Beder. The soil in which 

 we are, is nearly all granitic. The intolerable heat of the day has pre- 

 vented my excursions for some time past. The valley in which we are 

 is hotter than at Hydrabad. 



Monday, \2th April, 1819. — I traced the trap veins into the gra- 

 nite and farther east than I could follow it ; it is precisely similar to 

 that of Golconda, Suldapooram, &c. I nowhere observed it in contact 

 and passing into the granite. It extends as far as the eye can reach 

 in an easterly direction, sometimes forming considerable elevations, 

 and at others, sinking beneath the surface, is scarcely visible. 



Thursday, 22nd April, 1819. — Twenty-six grains of the green car- 

 bonate of lime were dissolved in nitric acid ; result to be hereafter 

 mentioned. About three miles to the N. W. of the cantonment I observ- 

 ed a long deposit of quartz rock. The whole of the above green lime 

 was dissolved except 3£ grains of green earth which remained behind 

 on the filter. 



Thursday, 29th April, 1819. — Specific gravity of calcedonic agate 

 from the Godavery. 260.
