great precipice^ like those of the Godumullay, shows many fine tints of 

 purple, red^ orang-e, and brown^ which show out very well under the rays 

 of the morning or mid-day sun: the iron mass generally is of a fine 

 brownish or greyish-purple colour. Close to the well-known temple of 

 Teertamullay, standing at the foot of the mountain on the north-west 

 side, the beds may be easily examined to great advantage on the 

 northern spur ; they there show a dip of 82° to the west. Tlie two beds 

 are continued northward as well-marked ridges, and extend beyond the 

 limits of our area. They are probably continued into the Ammapettah 

 hill, and prolonged thence for a considerable distance north towards the 

 Javadie hills. To the south of the Teertamullay the beds are lost in the 

 jungle under thick soil at about a mile and a half south-south-west of 

 the peak. The beds near the pagoda are of very rich quality, and 

 seem to have been extensively worked, if we may use such an expression 

 with reference to the numerous holes and burrows made in extracting the 

 iron sand from the decaying masses of the talus. 



The iron made from this ore is also held in high estimation. The 

 supply of ore here also is unlimited, the beds being of great thickness 

 (probably between 50 and 100 feet each, and possibly a great deal more) ; 

 no accurate measurement or estimate could be obtained at Teertamullay 

 pagoda where best seen, because of the broken state of the out-crop and 

 the great talus. 



As belonging to the Teertamullay group, we may with some pro- 

 Bed in Taultooky liability regard a bed of magnetic iron exposed in 

 ravme. ^j^g great ravine running south from Taultooky to 



the slopes of the TainandamuUay. The bed is exposed only for a few 

 yards on the north-west spur of the Shedayry peak (Chittairy) , but its 

 course would in all probability be traceable, if the adjoining dense jungle 

 were searched. 



The Teertamullay series is in all probability of much younger date 



T^ , , . ^ „ , . than the Godumidlay series, but the actual super- 



senes. position of the former over the latter series cannot
