DETAILED DESCRIPTIONS OF THE RlSSPECTIVE COALFIELDS. ^3 
with the Chindwin at Kalewa. Within an area of about one square 
mile he found 10 coal seams, only one of which, however, was of 
sufficient thickness to be workable. This seam is 10 feet thick, 
of fair quality, but friable. The dip is about 45'^. In 1889 a 
detailed examination of a large portion of the whole area was made 
by F. Noctling,'^ from whose report the following details are 
abstracted : — 
" The first group of outcrops occupies the Nantahin, Peluswa 
and Maku valleys, a tract of country 55 miles in length by one 
mile in breadth, extending from Kalewa in a northerly direction. 
The second or Telong group runs in a parallel direction, and 
extends up the Telong valley, the area being about 60 miles in 
length by 2 miles in breadth." 
The coal occurs in beds of various thickness up to 12 feet ; 
but seams of 2 feet and under are the rule. The average dip is 
at an angle of 45°. The greatest number of continuous seams occurs 
in the Maku valley, where twenty-five were counted. Taking all 
circumstances into consideration it was thought that a thickness in 
different seams of at least 24 feet of coal is available wherever 
the whole series of the Chindwin coal measures is developed. More 
precise information was obtained of the Nantahin-Peluswa area, 
which has a length of 25 square miles over which ground a total 
thickness of 48 feet of coal are considered to be available. It was 
calculated that down to an inclined depth of 1,000 feet from the 
outcrop there are 210 million tons of workable coal within this 
limited area. 
The coal is of hard texture, particularly in the thicker seams ; 
and in the 10-feet seam near Kalewa there are none of the part- 
ings of clay which depreciate the value of many of the other 
seams. Disregarding two samples yielding, respectively, 15| and 22 
per cent, of ash, the following is the average analysis of 13 different 
samples of the fuel : — 
Moisture 10-14 
Volatile matter ...... 34'59 
Fixed carbon ....... 49-95 
Ash 5-30 
Except for some small quarries near Kalewa which were at 
work for a short time in 1886, no mining has been done on these
