Moorabool, a fine face of white freestone with an underlying 2-ft. bed of pebbly 
mudstone is exposed. No attempt to open up the formation systematically 
has been made here, but a kind of trench or open cut from the top of the hill 
to near water-level has been shot out, filling the lower portion with the exca¬ 
vated material as broken. Although thus roughly treated, some fair blocks 
of stone of good quality can be seen in the mullock. 
The extent of the formation was not determined, but a length of over 30 
•chains is exposed in the Moorabool River. Overlying the area Tertiary 
deposits occur in places. To test properly what appears to be a good deposit, 
a face might be made on the top seam a quarter of a mile from the bridge, 
and a good cut put in at the upper quarry. 
The quarry is 2 miles south of Bradshaw’s Creek railway station, to which 
a tramway along the Moorabool River, to connect with the Ballarat-Melbourne 
line, could be easily constructed if the works suggested above were successful.

ALLEGED OCCURRENCE OF MINERAL OIL AT ANGLESEA. 
By E. J. Dunn, F.G.S., late Director , Geological Survey. 
From Geelong, via Torquay, Anglesea is 27 miles distant, and is situated 
on the coast at the mouth of the Anglesea River. Between Torquay and 
Anglesea is a Tertiary plateau about 400 feet above sea-level, with a steep 
descent to Anglesea. On both sides of the river limonite in moderate quanti¬ 
ties is exposed on the Tertiary hills, generally much intermingled with quartz 
sand or pebbles. On the beach this ferruginous conglomerate stands out 
conspicuously on the w T est side of the mouth of the Anglesea River, and about 
half a mile still further west. 
The coastline is marked by Tertiary cliffs from a few feet to 200 feet in 
height, and the sea is continually encroaching on these. In the cliffs the beds 
are well exposed. An anticline runs in a northerly direction about 20 chains 
to the west of the mouth of the Anglesea River ; the arch starts near the river, 
and dips under sea-level about three-quarters of a mile to the west. Black 
carbonaceous mudstone occurs at sea-level and rises for about 30 feet above 
sea-level at the anticline half a mile west of the river, and above this are beds 
of yellowish-grey and grey silts, with some thin bands of carbonaceous mud¬ 
stone. Beds of what appears to be volcanic ash about 4 feet thick occur above 
these beds, and on top of this again are red and grey mottled beds, apparently 
Newer Pliocene in age. 
Half a mile west of the Anglesea River the cliff section exposed to sea-level 
is 
feet.

Close by two bores were put down on the beach to a depth of 90 feet, all in 
black mudstone. From one of these holes it is stated an escape of gas took 
place, and that black mud was ejected from the bore-hole. The Anglesea 
River appears to run in a syncline, and a few chains to the east on the coast 
the black carbonaceous beds rise above sea-level. The beds appear to have 
not only been bent over in a wide fold, but also to have been faulted. Some 
boring to about 70 feet in depth was done on the east side of the river. 
The grey beds along the cliffs have an appearance and colour that would 
suggest that they were calcareous, but there is a total absence of lime in them. 
Yellowish-grey concretions are common in these beds, and some of this material
