On the Coal Fields and Coal Production of India. 509 
VII.—BoKaro.* 
The Bokaro field is situated in the valley of the Damuda com- 
mencing at a point two miles west of the termination of the 
Jeriah field. Its area is about 220 square miles. 
The groups represented in this field are precisely identical with 
those of the Ranigunj field, namely :— 
Mahadeva, : , ‘ : -- 
Panchet, - : , - -- 
Ranigunj, - : - : -- 
Ironstone shale, . : - - 1,500 feet. 
Barakar, : : - - -- 
Talchir, . : : ; — 
Some of the coal seams are of large size one of eighty-eight teet 
having been measured. The quality is generally inferior. Still 
there is no doubt that the field contains a vast store of valuable 
fuel. The estimated available coal is 1,5(0,000,000 tons. Except 
by outcrop workings nothing has been done to develope the re- 
sources of this field, owing to its position it is not likely, unless 
by the establishment of some local industry, that it will ever 
become available for useful purposes. 
VIII.— RamGura.t 
This field is situated to the south of the Bokaro field in the 
valley of the Damuda. Its area is 40 square miles. 
The following groups only occur as in the case of the Jeriah 
field ; it is uncertain whether the higher groups were denuded 
or were never deposited :— 
Ranigunj, > : ° = . 2 feet. 
Ironstone shale, ° ° . o Hl4010) 
Barakar, : : ° : - 8,000 ,, 
Talchir, - c : : 2) 2850'ee: 
4,050 
The coal is for the most part of poor quality and limited in 
extent. There are, however, a good many seains; possibly when 
opened up they may prove to contain better fuel than any which 
is now exposed in natural sections. But the ficld is unfavourably 
situated with regard to lines of communication.
