DETATLEn DESCRTPTFONR OF THE RESPECTIVE COALl'MELDS. (]5 
Padau river, 17 miles north of Kywaising. The coal is very friable 
and varies in thickness from 6 to 18 inches, occasionally pinching 
out altogether. The general dip is about G0° and the strata 
are much contorted. The following analyses of the coal have been 
made : —

The coal is a bright splintery substance of the nature of anthra- 
cite. It is non-coking. To burn it properly a forced draught 
is required, and very careful firing is necessary. It is excellent 
smithy fuel. Its main drawback is the small state of division in 
which it is obtained. 
In 1882 the Kywaising outcrops were tested ^ by tunnels and 
borings made under the supervision of the Local Government, and 
again in 1908 by a Rangoon Syndicate, but the disturbed condi- 
tion of the rocks and the transport and labour difficulties have 
up to the present prevented the exploitation of the deposit on a 
commercial basis. 
Thayeimyo. — Near Thayetmyo coal was discovered^ in the year 
1855, and a mine was opened which at first gave good promise 
of yielding a quality of coal that would have been most serviceable 
for the steam navigation of the Irrawadi. Owing to the beds being 
nearly vertical, mining would have been attended with considerable 
difficulty. This might not have proved an insurmountable obstacle ; 
but the fact that the two seams which were originally discovered, 
gradually merged into one, which ultimately died out, led to the 
abandonment of operations after a few hundredweights had been 
extracted. Another seam, also worthless, was discovered, according 
to Mr. Theobald,* near the village of Chouk-kalah on the Mu
