were put down under the supervision of Mr. La Touche, and with 
the evidence thus obtained, the latter considered that not more 
than 9 miUion tons of coal could be safely counted upon. The 
following assays of Daltonganj coal have been published : —

Between 1842 and 1862, collieries were worked at Pandua and 
Rajhara, chiefly by the Bengal Coal Co., who apparently extracted a 
considerable amount of coal, which they sent down the Koel river 
to the Ganges during the rains. In 1901, when the field received 
railway connection, the same company resumed the working of the 
mines. The output for the year 1910 was 84,996 tons.

Sind? — In the oldest Tertiary (lower eocene) rocks of Sind 
which have been named the Ranikot beds by Dr. Blanford, traces 
of lignite have from time to time attracted notice ; but in only 
one instance has anything more than a mere layer of a few inches 
been detected. The locaHty in question is Lainyan (Lynan or 
Leilan), 27 miles north-north-west of Kotri, and 15 miles from the 
^ . right or western bank of the Indus. In the 
year 1857, a shaft was sunk to a coal seam 5 
feet 9 inches in thickness ; but on driving out galleries the seam 
dwindled down to nothing while at the outcrop there was only a 
thin layer of carbonaceous shale. Dr. Blanford after paying a 
visit to the locality reported * that the deposit did not extend 
in workable form for a stone's throw in any direction whatever. 
The fuel is said to be extremely brittle and abounding in pyrites.
