a sixth, in the second Kundo Pani outcrop : the last is the head- 
water of the northward-flowing Kurasia Nala, for both the 
Gorirhehi and the Kurasia Nala rise at about the same spot. The 
height assigned to each series of outcrops in Appendix I is that 
of the top of the highest coal. The horizons may be numbered 
from 1 to 5 (or 6) from below upwards, the numbers really 
attaching to coal horizons rather than seams, for there may be one 
or more seams at each horizon, separated by stone or coaly shale. 
With these premises I may give the following abstract from 
Appendix I, showing the most probable correlation of outcrops, 
differences of elevation of the same seam being attributable partly 
to gradual dips in the succession of rocks, partly probably to local 
folds giving rise to sharper dips, partly no doubt to local faults, 
and partly to errors in the barometric readings. It is just possible, 
moreover, that larger faults not discovered may be leading me to 
an entirely erroneous correlation, as for example between the out- 
crops in the Gorghela and its tributaries on the one hand, and those 
lying east and north of Kurasia on the other.
