The most accessible of the outcrops of Vindhyan limestone from Warora 

 is at Kandaia, six miles to the north ; and the railway from Hinganghat 

 to Warora will pass either over it or near to it. There is another ex- 

 posure at Nilja, eight miles west of Warora, of much greater extent. 

 Lameta limestone occurs two miles south of Warora at Karamgohan ; 

 also in the Wardha river at Mardah, &c. 



The following analyses illustrate the variation in the composition of 

 the Lameta limestone at Karamgohan (Tween) : —

Kankar. — In the presence of rock limestone, kankar will probably 

 receive little consideration as a flux, but it may, with advantage, be 

 used under some circumstances. I append a few analyses, and these 

 demonstrate that it contains a high percentage of carbonate of lime : —
