1. Finely laminated gray gneiss. 
2. Crystalline limestone, containing spinel, gneiss, felspar, &c., 18 inches. 
3. Finely laminated gneiss, 6 inches. 
4. Coarsely crystalline limestone, containing graphite, light-coloured mica, and 
green crystals of augite, 50 feet. 
5. Very coarsely crystalline limestone in irregular shaped bands, alternating with 
ordinary crystalline limestone, probably 150 feet. 
6. Finely crystalline limestone, containing graphite, mica, aud spinel, probably 
100 feet. At mine e, in this, there is a band of grey gneiss, the foliation 
of which is inclined at an angle of 75°, corresponding with the inclination 
of the limestone in this part. 
7. Gneiss underlying the limestone just beyond mine e, probably 600 feet. 
8. Band of crystalline limestone, probably 150 feet. 
9. Gneiss.

This band is again seen cropping out in spurs near Pyanbin on both the east and 
west sides of the basin-shaped depression at l> mine. On the eastern side it has been 
exposed by the detrital covering, having been removed from its jagged surface, aud 
slopes south-easterly at an angle of 75°. On the western side it has the same dip, 
and rests upon the gneiss at the same angle, ft again appears on the eastern side of 
Kathay valley, but its greater portion onwards is hidden by alluvium as far as 
Panma village. From thence onwards it passes through the north-eastern side of 
Pingu hill, and is seen outcropping here and there through Bolong, Welloo, and 
Kyaukmyo, to Kabein (see Map, Eg. 11, p. 183). 
Some of the large bands north of Letnytaung pass eastwardly into the Kyaukwa 
valley towards Momeit, and eastwardly up the slopes of the Tanngnee range, and over
