have already been enumerated, as the red varieties 

 at Jaldrug and Bandola on the banks of the Krishna and the red 

 and green syenitic variety occurring at Gajendragarh (Gudjunturgurh 

 of Sheet 58) . A similar but less handsome red and green variety occurs 

 at Bilgij north of Kaladgi, underlying the basement beds of the 

 Kaladgi series. An exceedingly handsome but less markedly porphyri- 

 toid variety forms the high hill west of Mosulukal, in the Kaichur 

 Doab. It is a red syenitic rock with wavy laminations surrounding small 

 dark nuclei producing an effect like "bird^s eyes" in wood. It is 

 susceptible of a high polish and could be quarried in large and long 

 massesj the jointing being favorable.

of the last-named place, near Gagalu and Gugalu (Gaguloo and 



Googuloo of Sheet 57). A great supply of extremely handsome stone 



could be obtained at either of these localities.

than the basaltic rock now used.
