Buildln;/ SfoiK's oj Vicforia. 175 



This stone forms part of the same series of sandstones as 

 the Stawell stone, and is probably of carboniferous age. 



The quarry, although opened up in 1860, has not been ex- 

 tensively worked, and a lot of dead Avork has been done owing 

 to bad iron-staining and to a large fault. The beds dip west, at 

 about fifteen degrees into the hill, away from the quarry, which 

 is situated on the opposite side of the Wannon River from 

 Dunkeld ; \\ith the result that the cost with the present system 

 of carriage is increased. The cost of dressing this stone is about 

 •20 per cent, less than Stawell stone, but it has not the uniform 

 colour of the latter. Up to the present none of the troublesome 

 " flints "' of the Stawell stone have been encountered, but 

 " sand-balls," generally along the bedding planes, are met with 



Occasionally, hard, flinty bands up to an inch or two in 

 thickness and generally more ironstained than the surrounding 

 etone are met with, but these can be avoided. A marked defect 

 of this stone is the current or false bedding, which becomes most 

 pronounced on weathering, and may be seen very well in the 

 etone used in the recent additions to the Women's Hospital, 

 Carlton. Between the layers a fine argillaceous powder is pre- 

 sent, which falls away readily on weathering. This, together 

 with the differential ironstaining of the layers, gives the stone 

 after being in a building a very short time a bad appearance. 

 This stone has not been used to any extent, but may be seen 

 in the Hospital mentioned above, and in the Presbyterian 

 Church, Hamilton. 



Bart'cibool Hills Stone. 



This is a fine, even-grained sandstone, of a light green-brown 

 colour. It is quarried in the vicinity of Ceres, among the 

 Barrabool Hills, near Geelong. It is of Jurassic age, and forms 

 part of the widely distributed series of lake sandstones laid 

 down during Jurassic times. The stone is of fresh water origin, 

 and is made up largely of igneous material containing car- 

 bonaceous inclusions in the way of leaves and stems of ferns and 

 other plants. 



Its weathering properties are variable for different quarries, 

 but the samples investigated were obtained from McCann's
