North Sydney July 23-1913
First saw the "Millstone grit" a sand-
time heavily cross bedded. This gradually goes
over into the productive Coal Measures.
a series of dark shales with their gneiss
of sandstones and towards the top reddish
shales. In the Millstone we sees no
coral seams but on approaching the Coal
Measures they begin to appear. Under
most of the coral seams there is an old
gril and stipmaria roots and often we
sees Stipmaria clays amongst coal.
Plants are rare and most of these are
Stipmaria. In the shales as well
in the sandstones there is considerable
cementing matter. The thickest coal
seen this afternoon is 6 feet. There are
many seams from three inches up to 14 inches.
