of its class in India, contains more sand than water, gneiss is exposed, 

 and many of the pebbles of quartz picked up are of a green colour from 

 chlorite — water-worn pieces of kunkar, like finger coral, are also mixed 

 up with the sand. 



Madoor is close to this river, and is a small and as usual dirty 

 village, with much cultivation in tlie neighbourhood. On leav- 

 ing Madoor there are some hornblende rocks on the right and 

 close to the road— hills now at consideiable distance — ground in 

 long swells, and covered with stones and long grass — pieces of 

 quartz and hornblende on the road, very few rocks. Hornblende 

 slate in various places is seen passing across the road, with 

 much iron sand in the nullahs. About four miles before reaching 

 Mundiura, and previous to descending into a very extensive valley, con- 

 taining much black soil, a small conical shaped hill, with a pagoda 

 on it, is seen on the right-hand side of the road, but distant. It 

 has the same form as the chlorite hills near Bangalore ; on the road 

 chlorite slate is picked up in several places, and just on entering the 

 valley there are several rocks of chlorite and actynolite — brown exterior, 

 internal surface decomposing and ferruginous. These specimens vary 

 much, some are altogether of chlorite, others of chlorite and actynolite, 

 the needle-shaped crj^stals of the last very distinct, and some are very 

 hard and close grained — an argillaceous chlorite. In one place the rock 

 •was porphyritic, the basis chlorite with crystals of white felspar im- 

 bedded. This valley contains much black soil, with kunkar, and on the 

 Mundium side a stream runs along which has exposed the rock viz. 

 gneiss with large beds of hornblende slate — the felspar in this gneiss 

 of a snow v^^hite colour, with silver mica. Near the bungalow at Mundi- 

 um, outside the wall, are several rocks of hornblende, and on the other 

 side of the large tank salt is manufactured, but of a very impure kind. 

 It is obtained from the soil which in several places betwixt Mundium 

 and Madoor is full of it, and in which the palm flourishes. 



Two or three miles from Mundium on the Seringapatam side, the soil 

 is calcareous and clayey. Small pieces of kunkar, like marbles lying about 

 — the ground low and as if once much under water — some hills of slight 

 elevation, running parallel with the road on the left-hand side, and most 

 likely consisting of chlorite slate and actynolite slate, as some speci- 

 mens were found forming a water-course which passed over the road, 

 along with a porphyritic rock, met with, and to be described, in the bed of 

 the Cauveri near the Wellesly bridge at Seringapatam. In a deep 

 nullah near the road a little way beyond this spot, gneiss rock exposed ; 

 felspar red, with beds of hornblende slate, and veins of a calcareous sub- 

 stance resembling kunkar — kunkar in a valley below. Towards Seringa.
