70 GEOLOGY OF TRICHINOPOLY, &C. [ClIAP. IV. 1. 



6. Two miles north of Pompurapy. This is in all probability the 

 continuation of a bed which appears 



7. about 2 miles west of the village of Veraunganney^ 3 miles 

 south of Ravetnelloor hill, and which is traceable on the south side of 

 the mouth of the great Toombay valley. It is worked for iron sand at 

 Palayputty. 



8. Is an under-lying bed, having a nearly parallel course at a 

 distance of 2 miles to the south. Close to the village of Sangraveram^ 

 it makes a sharp turn to the north and becomes hidden under a spread 

 of paddy cultivation, but appears again apparently in the jungly ridge 

 south of Andipaleiyam. Bed No. 5 is very possibly nothing more 

 than a still more north-easterly part of the same bed. 



9. About a mile and a half south of the last named iron bed 

 (of Sangraveram) is another bed of larger dimensions, having a parallel 

 course, but dipping to the soath instead of the north, at an angle of 

 from 65° to 75°. The most northerly extension of this bed is probably 

 a bed showing itself about one mile south of Paukum tank, the junction 

 of the two parts being further indicated by a short out-crop of magnetic 

 iron occurring at the north end of a tank near Pandalum. The main 

 portion of the bed rises into a fine hill south of Pookanum tank. It 

 also forms the main ridge of two other hills of much smaller size between 

 the villages of Shellanputtoo and Yaretevanatum, and is lost sight of to 

 the south of the latter village. No connection could be traced between 

 this bed and some others of similar character on the south-east part of 

 the Kalroyenmullays. 



10. Eather more than a mile south of the Pookanum bed is 

 another of very poor quality, and note-worthy only because of its relation 

 with the three last described. At its western extremity, close to the 

 village of Curdy Chittoor, it makes a curious horse-shoe curve and is 



* Mis-spelt Sangraicram on map.
