DETAILED DESCRIPTIONS OK THE RESPECTIVE COALFIELDS, m 
Isa Khel. — These deposits arc situated in the Trans-Tndus 
extension of tlic Salt Range in tlie nciglibourliood of Isa Khel, in 
the Mianwali district. They were condemned as permanent sources 
of fuel by Oldham in 1864, but a later examination by R. R. 
Simpson ^ gives hope that m at least one locality, apparently 
only superficially examined by Oldham, mines might be established 
successfully. 
The coal is of two geological ages. The Jurassic or older beds 
attain their best development near the Indus in two localities in 
the neighbourhood of Kalabagh and Kuch. The seams are thin 
and inconstant, but it has been calculated that about 86,000 tons 
are available. Workings in these deposits have been carried on 
spasmodically for many years, but the total quantity extracted is 
insignificant. About 1,000 tons are said to have been mined in 
The younger coal, probably of Tertiary age, can be traced as a 
fairly continuous seam with an average thickness of 27 inches, 
between the Barochi pass near Mulla Khel to a point due west of 
Sultan Khel, a distance of about 6| miles. It has been calcu- 
lated that nearly half a million tons might be extracted from above 
the natural water level. In order to bring this coal to market a 
tram-line 16 miles in length would require to be constructed 
between the mines and the Indus at Kummuro, from whence the 
coal would be carried up the Indus in barges, a further 16 miles to 
Mari, the terminal station of the Daud-Khel branch of the Kundian- 
Campbellpur section of the North- Western Railway Company. 
In 1903 a mine was opened at Makarwal, the coal being carried 
on camels to Kamar Mashami on the Indus river, a distance of 
7 miles.
