construction of the Treasury, the Custom House and the Parliamentary 
Library. It has not since been used in Melbourne. When opening the 
quarries, the beds were found to be very variable in composition, and so 
full of joints, as to make it both difficult and costly to obtain the stone in 
quantity, of the uniform texture and quality, essential in large buildings. 
It constitutes, however, a useful building stone for local purposes, or 
where small quantities only are required. Excellent grindstones could 
be procured from some of these beds. The buildings, above referred to, 
do not present favorable evidence, as regards its durability, when exposed 
to the atmosphere of the city. Some of the beds are full of fossil-plant 
remains. Gangamopteris longifolius (McCoy) is the most abundant 
species, a specimen of which is seen on No. 17.

Note.—The Carbonaceous rocks of the Barrabool Hills, from which 
specimens Nos. 3, 18, 14, 15, 20 and 21 are taken, consist of a series of 
hard, thick-bedded, brown and grey sandstones, much jointed, and with thin 
veins of carbonate of lime ; they alternate with shales and conglomerates, 
and have an average dip of E. 30° S., at an inclination of 1 in 4. Over 
the area comprised between the village of Ceres and the municipality of 
Newtown and Chilwell, about 3,000 feet of Carbonaceous strata crop out 
at the surface ; the highest beds are found to the east and the lowest to 
the west. It is highly probable that this part of the series has been 
tested for coal‘in the Bellarine district, since an intermediate synclinal 
axis exists in the ground between Kensington and Geelong ; and the 
Barrabool Hills’ sandstones, shales, &e., would thus be a recurrence at 
the surface of those bored through in the Bellarine district. The sand- 
stones of the Barrabool Hills are extensively quarried and used for 
building purposes in and around Geelong. ‘They are very variable 
in composition and durability, and their prevailing dull greenish-brown 
color renders them objectionable for large buildings, in which architec- 
tural effect is required.
