 alluded to (seepag-e 65). — These are very rich at the

western extremity of their visible course^ but be- 

 come poor towards the east^ and appear to die out in the east and west 

 ridge lying to the north of Vetticaud. 



27. An iron bed occurs on the hill north of the Swaida Aur river 

 and opposite Conariputty. These two sources (26 and 27) supply the 

 iron sand for the numerous furnaces at Tummumputty and in several of 

 the adjoining villages. 



Both at Chindhariputty and Tummtimputty the iron stone has been 

 largely employed in the building of tank bunds and other coarse masonry. 



28. About 7 miles north-west of Tummumputty, and 1 mile south 

 of Shindalingy, and again about a mile south of Orumbur, are iron beds, 

 probably parts of one and the same bed. Their quality is rather poor. 



29. A small bed on the ridge north of Shindalingy. 



30. On the top of Keddamullay, about three quarters of a mile 

 east of the village of that name, is a rather poor bed. 



31. A small bed of rather rich quality close to the southern base 

 of Keddamullay. 



32. About 2 miles north-east of Rajapooram (Ransepooram) is 

 a curious horse-shoe curve, formed by a bed of poor iron stone, bending 

 as it were round a low hill. The ore is of bad quality and associated 

 with numerous crystals of coarse garnet and of the gold coloured horn- 

 blende-like mineral described as occurring in the Curdy Chittoor iron bed 

 No. 10. 



33. Four miles south of Rajapooram is a low ridge running along 

 the north bank of the river which drains the country between the Ivoly- 

 mullays and BoadthamuUay. Tliis low ridge, which extends for about 

 2 miles, consists in great part of a very poor bed of iron stone, abound- 

 in o' like the last in garnets in dodecahedrons. To the west it does not 

 appear to cross the Salem road, while to the east it re-appears after a
