outcrop, but the result was unsatisfactory. At this site there is abundance 
of marble of good quality suitable for the decoration of houses, and 
many other purposes. The very fine saccharoidal varieties of white 
marble were not observed, and probably do not occur. If this deposit at 
Stony Creek were within easy distance of the sea, or of a railway line, 
it would be extensively worked. Being in this extremely remote comer 
of the State, the transport by land is a severe handicap, and the cost of 
placing rough blocks in Melbourne under existing conditions would 
greatly exceed the price per ton at which European marbles could be 
landed there. 
This marble forms a portion of the Silurian series, and it is interesting 
to note near the quarry how the slate beds give place to mudstones that 
are at first thinly studded with fossil remains. These become more 
plentiful as the beds rise in the series,- and then the marble beds supervene. 
Above, the marble beds alternate with highly fossiliferous calcareous 
beds, and then these calcareous beds alternate with mudstones and grits 
thickly studded with fossils. As the beds rise higher in the series the 
fossil remains become scantier. 
Below the horizon of the quarry are fossiliferous mudstones ; then 
lower still slates, and appaientlv still lower the marble deposit, which is 
so extensively developed here. 
A little to the north of the quarry, in the bed of Stony Creek, the strike 
of the mudstones is E. 30 deg. N., and they dip N. 30 deg. W. at 27 deg. 
The height of the quarry is about 3,100 feet above sea-level. 
The principal caves are likely to be found in the No. 5 outcrop on the 
northern side of Limestone Creek, and exploration would probably result 
in the discovery of other small caves in the outcrop near the hut on the 
southern side of the creek, but with the exception of one or two small 
depressions in the surface at the Stony Creek outcrop there was scant 
evidence of the existence of caves. 
Professor Skeats and Mr. Summers, the sculptor, were, with me when 
the examination of these outcrops was made. Mr. Summers was inde¬ 
fatigable in testing the qualities of the stone, and can speak with con¬ 
fidence as to its value for various purposes. 
The visit was a brief one, as provisions had to be packed in. As the 
proper detailed examination requires much more time to be spent on the 
ground, it is intended to send a geological officer and party to thoroughly 
surver all the outcrops, to show their relations to the surrounding rocks, 
and to fix their positions relatively to one another; also to secure as great 
a variety of samples of marble as possible, together with tvpical fossils. 
These deposits have been reported upon by Dr. Howitt in Prog. Rept. 
Geol. Surv., Vic.,- No. III., 1876, p. 195; and bv Mr. Jas. Stirling, in the 
Quarterlv Report, Department of Mines, Victoria, 30th September, 1889.

THE COAL CREEK MINE, KORUMBURRA. 
(NO 24 ON LOCALITY MAP.) 
By E. J. Dunn , F.G.S., Director , Geological Survey. 
While at Korumburra selecting a site for coal boring in the vicinity, a 
visit was paid to the Coal Creek mine, and the underground workings. 
The coal seam is 3 feet thick, with a |-in. “ pricking” near the bottom 
of the seam, which is soft and useful for holing. The mine is equipped 
with hauling and pumping plant, tramway several hundred yards long to 
the railway, &c., and the output is 70 tons of coal per day. Needless to 
say, such a small output is unsatisfactory when the standing charges would
