Geology and Physical Geography: 
In the central portion of the area, on or adjacent to a line from 
Moe to Cape Patterson, are several coal outcrops, the most im- 
portant of which is the Strzlecki seam, about 14 miles north from 
Anderson’s Inlet. 
There are two outcrops less than 2 miles apart, but whether 
of the same or of different seams is uncertain. The northern 
exposure is on a western tributary of the Tarwin, near the divide 
between that river and the Powlott. 
In a cutting there is exposed, in a height of 7 feet, an aggregate 
thickness of 3 feet of good coal, in three separate seams of 12 
inches, 8 inches, and 24 inches respectively, the lower 18 inches 
of the latter, or undermost seam, being very good indeed. 
The southern outcrop is in a gully trending to the Powlott, 
and here a short tunnel has rovealed the existence of a seam (dis- 
located to the extent of 3 feet in one place by a “ fault”) con- 
taining at the face of the tunnel an uubrokeu thickness of from 
30 to 32 inches of excellent coking coal. 
Whether the same or different seams, there is good reason to 
believe that the coal exposed in these two outcrops underlies a 
great area, and the discoveries made by means of so small an 
amount of labour amply justify further research. 
In the heads of the Tarwin, between the Strzlecki seam and 
Moe, are several other outcrops, some of which show as much as 
16 inches of good coal ; but none of these, so far as I am aware, 
have been in any way tested as to their extent. 
The most important seam yet found in Victoria is the Mirboo 
seam, the outcrop of which is in Berry’s Creek, about 2 miles 
from the Mirboo Railway Station, on the property of Mr. William 
Starlett. A shaft sunk a short distance from the outcrop passed 
through the seam at between 40 and 50 feet, and revealed a 
thickness averaging 56 inches of solid coal. The seam dips at 
the high angle of 32° in the shaft, but as the rocks exposed 
at surface up the creek, in the direction of the dip, show a 
muc flatter inclination, it is certain that the seam will conform 
thereto. 
Considering its size, quality, and proximity to the railway line, 
there appears no room for doubt as to the remuneratively workable 
character of Ibis coal soam if properly wrought. 
The Boola.a seam has recently been found in the bank of a 
branch of the Morwell, about a mile and a half from the Boolara 
Railway Station, and close to the Mirboo line of railway. This 
seam is 3 feet thick, and though the upper portion is somewhat 
impure near the outcrop it is of workable size. It is nearly hori- 
zontal, and can be easily worked by means of an adit. It is quite 
possible that this seam may be identical with the Mirboo seam, 
though the distance between the two outcrops, and the paucity of 
any data as to the dips and undulallons of the rocks in the inter- 
vening tract, forbids more than the mere ee ijecture.
