ECONOMIC GEOLOGY. 265 



important examples of their use are the ancient fortified city of Ferozabad* 

 on the Bhima (which was entirely built of the limestone) , the town 

 of Talikot on the Don River, and various new buildings belonging to the 

 Great India Peninsular Railway. The limestone is so much esteemed that 

 it was and is still carried to considerable distances beyond the boundaries 

 o£ the Bhima basin. As already mentioned [a7iie, p. 154) the cream-colored 

 variety is the most esteemed locally, and justly so, for it gives a very 

 pleasing appearance to the villages which are built of it. 



Experiments on the value of the stone for lithographic purposes 

 have been tried both in Bombay and Madras, but they cannot have been 

 successful, for no demand has arisen for it for such purposes. 



A few small slabs of the grey and purple varieties are to be seen 

 used as panels in an oriel window in the very beautiful little building 

 known as the Mehtri Mahal at Bijapur. 



One very interesting application of the Bhima limestone in very 



ancient times was to the manufacture of chipped 

 Chipped implements. . 



stone implements^ several excellent examples of 



which were found by me near Yeddihalli (see p. 162). 



Iron pyrites occurs in tolerable quantity in some of the limestone 

 beds, and is (or was) used for the manufacture 

 of sulphur at Mudanur (Moodanoor) in Surapur 

 Taluq according to Colonel Meadows Taylor.f 



Of the quartzites and sandstones some use is made in building, 

 especially near Muddebihal, and hand millstones of good quality are 

 quarried in some quantity at Inuchgal, some seven miles to the north- 

 east by east out of a bed of pale purple grit containing occasional 

 green chloritic grains. 



Rude flagstones of large size from a semi-schistose semi-con- 

 glomeratic gritty sandstone immediately under- 

 lying the Talikot limestone between Tirth (Teertu 



* Founded about the end of the fourteenth century by Peroze Shah, 7th King of the 

 Bahmani dynasty. 



t I was not aware of the existence of this industry when I visited Mudanur ia 

 1870, so made no enquiries as to the extent to which it is carried on.
