BALL AND SIMPSON: COALFIELDS OF INDIA. 
11 miles west of Indeinmyo. The thickness of the bed varies 
from 2 to 3 feet, and in one case 6 feet The dip is from 15° 
to 45°. At a later date outcrops of a similar lignite bed were 
found at Nangon, near Pwehla by C. S. Middlemiss ^ who also 
examined what he considered to be a continuation of the Panlaung 
and Legaung coal seams at Payabyu (Po-pyu) near Inwin, 8 miles 
south-west by south of Thamakan. He also visited the outcrop at 
Ngotko-Yagyi (Mr. Jones' "Ngu"), and characterised the mineral 
as graphitic shale. A similar material is said to occur- north-east 
of Thit-e-bin, near Pindaya. 
Northern Shan States. — Beds of lignite of late Tertiary age 
have been found to occur in scattered basins occupying depressions 
in the ancient Palaeozoic floor of the Northern Shan States. Four 
of these known as the Lashio, Namma, Man-Sang and Man-Se-Le 
coalfields, have been examined and mapped by officers of the 
Geological Survey. 
Lashio.'^ — The area of this coalfield is about 50 sq. miles 
and it lies within two or three miles of the terminus of the Manda- 
lay-Lashio railway. Outcrops of coal have been found at several 
points, but owing to the thick coat of alluvium which obscures 
the rocks no attempt at correlating the seams and estimating the 
amount of fuel can be made without recourse to boring operations. 
The thickest outcrop measures 25 feet, whilst others are 3, 51, 
6 and 11 feet in thickness. Bulk samples of the thick seam were 
recently obtained from inclines sunk by the Burma Railway Com- 
pany. After trials the coal was condemned as a locomotive fuel. 
It is a brown-black lignite, disintegrating on exposure to air. 
Representative analyses are : — 
Namma? — This coalfield lies 11 miles south of the Lashio 
field, and is of about the same area, i.e., 50 sq. miles. The
