of flesh-colored felspar in blocks with stripes and lumps of quartz, also 

 mica slate and granite, with a large quantity of green hornblende,* the 

 decomposition of the hornblende leaves a greenish yellow clay very 

 plastic ; my time was so short that I was not. able to search for the 

 junction of the primary rocks with the iron clay. The heavy rain pre- 

 vented me from opening the Palanqueen, so that I lost the termination 

 of it. I saw it for the last time about 3 coss from Nyarpet. 



Saturday, 2\st November 3 1818. — Just after quitting Goodoor, I 

 observed large masses of granite cropping out, with a very large pro- 

 portion of white felspar : during the day large pieces of quartz, sand- 

 stone, and iron clay were strewed along the road, but no rocks visible. 

 In the neighbourhood of this village Venkatachellum, there are large 

 masses and the tanks are built of the latter. 



Sunday, 22nd November, 1818. — Nellorealong dirty town, built on, 

 and partly of, the iron clay, which is here to be seen in an imperfect 

 sort of stratification or rather seams which are neither parallel nor 

 horizontal. I saw a well, 20 or 30 feet deep dug through the iron clay, 

 which resembles very nearly those specimens presented to Mr. R. by 

 Col. M. said to come from Mysore. 



Monday, 23d November, 1818.— Paid a visit to Mr. Sutton at 12 

 o'clock, and went with him to see the quarries of iron clay. In one 

 place over a stratum of it, the mould was upwards of fifteen feet in 

 thickness and in others less. 



I observed pieces of brick and pottery, close to the surface of the 

 clay in the vegetable mould. An antique figure of Buddha built into 

 the masonry that forms the foundation of Mr. Lord's house near the 

 quarries, has a very picturesque appearance. I also visited the iron 

 clay in the banks of the Pennar, where it is seen on the right bank in 

 great abundance : the bed of the river, which is very much choked up 

 by alluvium, and therefore much higher than when the pagoda was 

 built on its banks, is now effecting serious breaches in the wall sur- 

 rounding it, as well as in a little temple or Chauvadi built on an elevat- 

 ed portion of the iron clay. The alluvium of the Pennar is entirely 

 silicious, mixed with a few shells. I bathed, and found the water, where 

 we crossed, brackish. The iron clay of this neighbourhood contains 

 more cellular cavities and more brown hematite than I have hitherto 

 * Epidote ? undetermined.
