the seam was white sandstone, somewhat calcareous. In No. 3A., the 

 coal was struck at a depth of 135 feet from the surface, the total thick- 

 ness of the seam, including the top carbonaceous shales, was 17 feet. This 

 section illustrates how the amount of coal diminishes when the seam is 

 met with near the surface, the thickness of the seam in No. 2A. being 30 

 feet (including the top carbonaceous shale) . 



At Rajur, which is to the south-east of Warura, coal was proved in 



p ... 1870, in a bore-hole (No. 1), the site of which 



was pointed out by myself. As the intention at 



that time was merely to test the continuance of the coal under the upper 



rocks which cover the whole surface there, the rods were withdrawn 



after 15 feet of the seam had been cut into. 



More recently, in extension of the Warura explorations, additional 

 borings were made on the Parsora side of Rajur. The first of these 

 (No. 2) Mr. Smyth undertook to place within a moderate distance of 

 the Kamthi and Barakar boundary, to ascertain whether the thick coal 

 might not be met with near the surface ; but like the hole No. 1 A. Waru- 

 ra, the attempt was unsuccessful. It would appear to be a waste 

 of energy looking for it without allowing a considerable horizontal 

 distance for overlap. No. 3 bore-hole was placed nearly fths of a mile 

 from Rajur, and the coal run into at 114' 9' / from the surface. Thick- 

 ness of seam 22 feet. The next hole (No. 4) was situated half-way be- 

 tween No. 3, Rajur, and No. 3, Parsora, and coal was found at 202' 10". 

 Thickness of seam 25' 6" and, as usual, there is a roof of black carbona- 

 ceous shale. 



The most southerly of the recent series of holes are those of 



Parsora seam 31' 0". ParS ° ra ' N °' 1 ***** sH ^% n0rth ° f ^ 



from the village. It was pointed out by myself, 



and coal roughly calculated to occur at 250 feet. The chisel, however, 



passed through a band of clays and argillaceous sandstones, and 



progress was so impeded by the difficulty of keeping the hole clean, that
