XIV.—HUTAR.* 
This field lies to the west of the Aurunga, being situated more 
directly in the valley of the Koel. The area is 78°6 miles, and 
the following groups occur :— 
Mahadeva, . : 4 6 C 1,000 feet. 
(Ranigunj ?) 4 
Barakar, \ ; ; : - 2,750. ,, 
Talchir, : ‘ : : : 5 300 ,,

Data for the estimation of the quantity of available coal are 
wanting, but there are a considerable number of seams, and the 
average of eight assays, gives the following favourable result :—

This field is also in the valley of the Koel, district of Lohar- 
dugga. The area is 200 square miles. Two groups only are 
represented, viz., the Barakars and Talchirs, the latter being about 
500 feet thick. 
Seams of coal are not numerous ; one, which has a thickness of 
about 5 or 6 feet, contains excellent fuel, according to the Indian 
standard, as the following average of four assays, amply testifies :— 
Moisture, : 9 5 : : . 3845

The estimated total of available coal is 11,600,000 tons. 
This field has been worked to a small extent from time to time. 
There is some prospect of its being now opened up in con- 
nexion with the Sone-river canal system.
