known Kunjamullay beds, will be added as an appendix. No magTietic 

 iron beds were noticed south of the Cauvery, nor to the east of the meri- 

 dian of 79" 10' east longitude. 



The iron beds which are most important in extent and richness 

 lying within our area are those belonging to the four following groups : — 

 1st. — The Godumullay group, east and north-east of Salem. 

 2nd. — The TullamuUay-Kolymullay group. 

 3rd. — The Singiputty group. 

 4th. — The Tirtamullay group. 



The Gochimiillay grotip consists of two great parallel beds running 

 from a spot about 9 miles east by north of Salem, 

 along the ridge of the Godumullay ; it crosses the 

 Yellaur river at Valoor, and runs along the ridge of the Valoor hill. The 

 exact course of the out-crop then becomes obscure, owing to thick jungle 

 and debris of other rocks occupying higher positions j but about 2| 

 or 3 miles to the north-east, another smaller and poorer iron bed 

 appears in such a position that it must be considered the continuation 

 of the lost beds. This bed is distinctly traceable 

 up a long spur of the Neighemullay (pronounced 

 Nayaymullay) to the village of that name, on the east side of which 

 two large and rather rich beds form the edge of the plateau ; where 

 the ground falls at the north-eastern end of the small plateau, the 

 two beds are hidden by thick jungle, but they re-appear about \\ mile to 

 the north-east at the village of Manoor, and in less than a mile to the 

 north, are again hidden by thick jungle. They do not re-appear in the 

 Tandumputty valley, being doubtless hidden under the thick accumu- 

 lations of soil j but 3 miles to the north of the last named village, 



close to a small Mullayali hamlet called Vulshay 

 Vulshay beds. 



(Valassy), several beds of good ore show on the 



very steep slope of the hills, but are not sufficiently exposed to enable 



one to judge of their size. North of Vulshay these beds are again lost
