planes of which seem almost as various as their flexures. At the distance 

 of a furlong and 100 yards S. E. from Nundapur, a red felspathic dyke 

 occurs in the gneiss, almost concealed by a superincumbent mass of 

 friable kanker : small crystals of a scaly graphite, with a shining steel- 

 like lustre, occur disseminated in this vein. The gneiss alternates with 

 chloritic slate and beds of a red felspar rock : its laminae are much con- 

 torted, and have here an easterly direction. One mile and a furlong in 

 the same direction from Nundapur, the bed of a stream is crossed, 

 where a dyke of a compact reddish felspar rock (Eurite ?) cuts the gneiss 

 in a direction of N. 60 E., flanked by a thick bed of reddish felspathic 

 granite, containing both mica and chlorite in lamellae, and a little quartz. 

 This rock and the gneiss are much weathered. Six furlongs hence, the 

 gneiss assumes a granitoidal form, appearing in rounded blocks with 

 concentric exfoliations. Three miles from Nundapur, a trap dyke 

 crosses the gneiss, running westerly ; and another, at four miles five 

 furlongs, having a similar direction. A furlong from this, a large dyke 

 of the red euritic rock, about 200 yards broad, occurs in the same direc- 

 tion, flanked by a bed of the red felspathic rock, large beds of kanker 

 accompanying the intrusion of the dyke. I saw an immense bed of 

 this calcareous rock, lying as a flat table on the gneiss near Manadhal. 

 From this place to Kannaghirry, a distance of eleven miles one furlong, 

 gneiss, granitoidal gneiss, forming gentle elevations, and scattered sur- 

 face blocks occur; the associated schists of chlorite and mica are less 

 seen. A trap dyke occurs at the distance of five miles five furlongs 

 from the former village ; direction W. 15 N. 



In the bed of the stream, forming in part the fosse of the fort of 

 Kannaghirry, gneiss is seen alternating with mica and hornblende 

 schists, both thick bedded and laminar. On the N. E. flank of the 

 fort, a dyke of pegmatite, with a close small grained sub- crystalline 

 structure, is seen passing through the gneiss, and in a direction parallel 

 with that of the laminae. In the latter rock, a vein, (five inches broad,) 

 of large crystals of felspar and quartz running N. 25 E., exhibits a dis- 

 location to the E. of seven inches. A fissure traverses it for some dis- 

 tance longitudinally, running also into the schist. The walls of the 

 fissure are lined by quartz passing into hornstone. 



About four miles North by West from this, near the village of Ha- 

 numanhal, I saw on the road side a monument of a Hirlu, or a hero
