it must now no doubt have changed its bed materially, since tradition 

 places the pagoda many years ago, far from its banks. The temperature 

 of the river at 12 o'clock was 74°, the same with the air. The basalt of 

 which the pagoda is built is in some parts of the building finely polished. 

 It contains olivine. The granite much resembles that found near Bacha- 

 pilly at the Bear's rock. It is porphyritic containing large crystals of 

 red felspar in a crystalline cement composed of quartz, compact felspar 

 and mica. This is the prevalent rock. A porphyritic greenstone lies 

 near it, apparently in beds, in which the crystalline felspar is compact 

 and of a green colour arising from green hornblende ? I believe them 

 to be the same with those of the Bear's rock at Bachapilly. The dis- 

 tance from Thevalingapate hill is 12 miles and the sole rock is the 

 trap, sometimes basaltic, sometimes wacke on the elevations, and in 

 the plains black cotton soil. 



Monday, 22nd February, 1819. — On quitting this place the ther- 

 mometer stood at 47° and the temperature of water at 5j o'clock a. m. 

 was 43° ; a march of 7 miles brought us to Monegal : nothing but trap 

 of which I am heartily tired. 



Tuesday, 23rd February, 1819. — The formations in this part of 

 India differ materially from those of Europe ; no chalk, no intermediate 

 rocks between the trap and granite. The whole field of view, probably 

 an extent of 20 miles. The ravines of the formation are much deeper 

 than usual. 



Sunday, 27th February, 1819. — Large beds of wacke began now to 

 appear, generally lower, or at the bottom of the more elevated trap hills. 

 On arriving near, a temple with a basaltic column similar to one I had 

 seen on the banks of the Godavery struck me, and I made an attempt 

 to draw it. 



Monday, 28tk February, \8\ 9. — The river bed differed very little from 

 that of the Mulinar. I followed it until I came to the same or a similar 

 appearance, which had before struck me : large masses of red granite 

 imbedded in a coarse cement of limestone, containing crystals of felspar 

 quartz, &c. I drew a sketch of the banks which bore a great resemblance 

 to those of the Mulinar and Manjera. We arrived at Buhtalipoor. In 

 the evening I visited the formation of wacke, to ascertain a fact men- 

 tioned in Thomson's Annals, confirmed. It was not calcedony in wacke.
