eastern side the limestone presents an abrupt face of about 80 feet in height, 
and it is here the quarries and kilns are situated. Several acres of limestone 
exist, but as the western extent of the limestone has not been determined 
it is impossible to say what the total area is. There is certainly a thickness 
of 80 feet, and the bottom has not been reached. The quarry has a face 
80 feet wide. 
The limestone consists principally of comminuted fragments of coral, 
shells, &c., and appears to be entirely composed of organic remains. There 
is a great variety of shells in fairly perfect condition; the fragments 
appear to be somewhat rounded. Clay pipes show in the face of the 
quarry, and as this material is valueless and has to be removed, it is an 
undesirable feature. There is an overburden of from 2 to 3 feet of soil 
covering the limestone. 
Fuel is abundant, and the lime can be burnt cheaply and delivered at 
a low cost on to railway trucks. At present, most of the lime burnt in the 
two kilns is used for building purposes, but the demand in this direction 
is insufficient to maintain an output that would be profitable. There are 
great tracts of agricultural land close by and away northward that would 
greatly benefit by lime dressings, and if the industry of lime-burning is to 
become a prosperous one this field of consumption must be exploited. 
At present, the lime can be delivered into trucks at is. 3d. per bag, 
18 bags to the ton. If large quantities were required for agriculture, this 
price could be very much reduced. The occurrence at this site so close to 
the railway renders it a very valuable one. 
On analysis a sample of this limestone showed carbonate of lime 
88.02%, insoluble silica 3.48%. This shows the limestone to be of fairly 
good quality, and quite good enough for agricultural purposes and for 
building also, although not quite so strong for this latter purpose as the 
Geelong lime. There is scope for widely extending the industry at this 
site when the value of lime for agriculture is more fully appreciated.

NOTES ON COAL AND COAL BORES IN THE DEAN'S MARSH 
AND BEECH FOREST DISTRICTS. 
By E. J. Dunn , F.G.S., late Director , Geological Survey. 
Dean's Marsh. 
No. 1 bore, Boonah Parish, is situate near the road from Dean’s 
Marsh to Lome, and is 7 miles distant from Dean’s Marsh. The bore is 
on a slope a short distance off the main road. It is 220 feet below the 
ciest of. the ridge, and 130 feet above the bottom of the valley where the 
brown coal seam was worked. The top of the bore is 1,140 feet above 
sea-level. From the surface to 300 feet the beds are Tertiary 7 clays, soft 
sandstones, &c. At 164 feet a bed of impure lignite, 4 ft. 2 in. thick, was 
pierced. From 300 feet grey and greenish-grey Jurassic sandstone, bedded 
at an angle of about 40°, was drilled through for about 150 feet. 
Below the greenish-grey sandstone, grey and dark-grey sandstones, with 
abundant films of coaly material, and bedded nearly horizontally, were 
drilled through to the present depth of 800 feet. There is a general 
absence of the dark to black shales usually found associated with coal 
seams in the Jurassic coal measures, and so far as the boring has proceeded 
the indications are not favorable. The search work now being carried on 
in the Otway district is purely exploratory, and until further data are 
accumulated the work of boring can only be conducted on empirical lines.
