" The shell kunkur is found in large quantities between the Naudh and Burnah Nud- 

 dies, at a depth of 15 to 20 feet under the surface of the country. The. specimens are 

 from the village of Pindra on the road from Benares to Jounpoor. Towards the 

 Naudh Nullah the shells in the kunkur are in larger quantities than in the kunkur 

 about the Burnah. It is found in one uninterrupted sheet from 15 to 20 miles in extent 

 varying from one to two inches in thick aess. The kunkur is eagerly sought after for 

 Lime, which is purer and more valuable than that made from the common nodular 

 kunkur. 



" Small wells are dug, barely wide enough to admit the workman, and when he 

 arrives at the stratum of kunkur he works laterally as far as he can with safety, breaking 

 up the kunkur with a pickaxe. 



" The kunkur is too soft to be used as metal for roads." 



I enclose you a sketch of the various shells — natural size ; and have sent per dak bhan- 

 gy a small box containing some detached ones.

Museum of Economic Geology. 

 I have been mostly employed in the Laboratory during this month, but have not suffi- 

 ciently completed any thing to report upon it with confidence . 



The collections of the Coal and Iron Committee have been received into the Museum, 

 but I have been obliged to delay arranging so as to report upon them, in order to get the 

 cases painted.
