_ NOTES ON THE CREMORNE BORE. 449 
The following are sections of the seams at Amos Brothers 
Bore near Wallarah and at the No, 2 Bore, Cremorne, placed side 
by side for comparison :—

with minute veins of calcite 
0 02 sandstone 2 9 (about) coal splint and bituminous 
of good quality 
0 01 band dark brown clay shale 
adhering firmly to coal.

good quality, the last 3 inches 
rather soft and bituminous.

Not only do the sections of these two seams agree tolerably 
closely, but the section of the two seams next below this top seam 
in the Newcastle and Illawarra Coal-fields respectively, also 
agrees, a seam four feet in thickness usually underlying the seam at 
Wallarah in the Newcastle Coal-field and at Bulliin the Illawarra 
Coal-field, and a seam fourteen feet in thickness underlying the 
four feet seam in places at both these coal-fields. The last men- 
tioned seam however, in the Jllawarra Coal-field is split up into a 
number of smaller seams at several localities. It is typically 
developed at Wongawilli near Dapto. 
One important scientific result of the Cremorne Bore is there- 
fore the practical settlement of the question as to the identity of 
the Newcastle Coal Measures with those of the Illawarra Coal-
