102 Report on the Coal said to have been found 
but has a marked tendency to crystallized structure, and is 
intersected with numerous very thin veins of calc-spar : its 
colour is a pale blue; it has yielded no fossils, and gives no 
indication of stratified form, notwithstanding it lies close 
alongside an almost vertical wall of regularly stratified clay- 
slate. The quarry is situated in a little valley, almost 
surrounded by low hills of clay-slate, whose beds dip to the 
eastward, at a high angle. Contiguous to the limestone the 
clay-slate is dark-coloured and fissile, and contains much 
sulphuret of iron. Upon a little hill on the eastern side the 
slate becomes bluish yellow, and its lamine split easily 
into thin rhomboidal plates; but the formation then alters 
almost immediately, passing through a soft laminated clayey 
flagstone into thicker beds of arenaceous conglomerate : 
the slate is at best too soft and absorbent to be of any 
economic importance. 
Discovered at first by some accident, this limestone has 
been worked over a limited area, but to a considerable depth; 
and latterly at a serious cost, water having become so 
troublesome as to render the employment of several pumps, 
moved by a powerful water-wheel, necessary. 
It is probable that when fully known this limestone will 
prove to be of the same age as that at Crickton, an estate 
of Mr. Abraham Walker, on Norfolk Plains ; and that upon 
Lachlan Marshes, at the foot of the Frenchman's Cap range, 
on the western side: but data are still required either to 
establish or disprove the identity conclusively. ‘The surface 
of the country between Mr. De Little’s lime-kilns and the 
Asbestos Hills is moderately timbered, and yields only a 
scanty pasturage: clay-slate undulations of no great eleva- 
tion, capped at some points by greenstone, with narrow 
intervening vallies running nearly parallel to the line of the 
Asbestos Tier, constitute its geological character.
