Geology and Physical Geography : 
statement made in a former report — that we had, at the time that 
report was written, no guarantee as to the continuance of any 
known coal seam beneath a single square mile — may now be with- 
drawn. We have ovidence of their continuance beneath many 
square miles, and of the probable existence of many millions of 
tons within a short distance of the surface, and within convenient 
distance of a shipping place. 
From the mouth of the Powlett River, 3 miles cast from Kil- 
cunda, for a further distance of some 4 miles, nothing is to be 
seen of the rocks along the coast ; but thence for 12 miles, 
by Coal Creek and Cape Patterson to within a short distance of 
Anderson’s Inlet, they are visible the whole way, and alTord 
excellent opportunities for observation. 
At about the first exposure of rocks on the coast, travelling from 
the Powlett towards Coal Creek, there are three small seams, and 
further on a seam of about 10 inches of good coal with several 
feet of black u clod beneath it ; these are only visible at times 
when the tide is low and the sand temporarily removed. About 
this locality it is stated that a seam of 20 inches was proved 
inland among the hummocks, but has since been obscured by 
blown sand. 
A mile westerly from Coal Creek is a coal seam of from 20 to 
24 inches between two smaller ones of 4 inches each, all dipping 
N.W. at 40°. This dip is exceptionally high and abnormal in 
direction, the rocks on both sides, for some distance, dipping from 
S.S.W. to S.S.E. at from 4° to 14°. In this locality, however, 
much disturbance, variation of dip, and false bedding are visible 
in the strata. 
Two or three other small seams occur between here and Coal 
Creek, west of the mouth of which are the two main scams, the 
“ Rock ” and the “ Queen ” veins. Where exposed on the coast, 
these scams dip W.8.W. at about 30°, but in a shaft (known as 
Bury’s or Davis’ shaft) suuk through them a few chains inland, 
the inclination is only 15°. 
The section iu the shaft is as follows : — Measures (sandstones, 
shales, &e.), 57 feet. Upper coal seam — total thickuess, roof to 
floor, 30 to 36 inches, with irregular partings, reducing the avail- 
able thickness of coal to about 24 inches. 
Measures with a small 4-inch seam, 1 1 feet. Lower coal seam 
— total thickness 42 inches, divided by impure bands into three 
portions of 2\ to 3, 2$ to 3£, and 22 to 24 inches respectively. 
These measurements represent the general average, as no two sets 
of measurements taken, whether in different parts of the shaft, or 
on the coast outcrops, tally exactly, owing to variations in the 
thickuess of the coal and partings. 
On the whole, I would estimate an available thickness of 24 
inches of coal to be the average for each seam as now visible.
