132 BUILDING STONES OF QUEENSLAND. 



sufficient size can be obtained for making good-sized columns 

 with the bedding horizontal. The columns in the Executi\e 

 building are of this stone and are a little over 8 feet long. 



The stone is eas}' to quarry as there is little over- 

 bm-den, the jointing is far apart and the bedding horizontal, 

 the situation of the quarry is good as it is at the foot of a 

 hill and can be worked back a long way, and it is within 

 half a mile of the Yan Gan railway station. 



Tests on this stone in 1901 gave the following results : 

 an a\ erage resistance to crushing of about 2,8001bs. per sq. 

 inch on three samples tested, absorption of 8.7 j)er cent., 

 and a specific gravity of 2.611, which gives a weight of 

 1631bs. per cubic foot. Three tests for absorption by the 

 author on specimens from the present quarry face gave an 

 average of 6.1%. This is higher than one would anticipate 

 from the stone and considerablj' more than 3-4% which is 

 generall}^ regarded as the safe limit in cities with a trying 

 climate. The low resistance to crushing is in keeping with 

 the high absorption. 



The stone has been used in the Executive Building 

 (iV)Ui-5) in the columns and recessed walls of the 

 William Street, Queen's Park and George Street fronts, 

 and for the upper stories in the front on to Stephens Lane 

 (see test-fig. 11). It has been used in the front of the 

 Royal Insurance Co. Buildings (1906) in Queen Street, on 

 a base of Mt. Crosby granite, also in the Bj^rnes' Statue 

 on a base of Enoggera granite. The very fine manner 

 in which this stone dresses can l^e well seen in these 

 structures. 



In WarAA'ick, it has been used in the Police buildings, 

 the Post Office, the sandstone facings of the Technical 

 College and the 1912 additions to the Warwick railway 

 station. 



Swan Creek or Mt. Sturt Sandstone. 



This is a brown sandstone which is knoAvn under 

 both the above names. The quarry is about 9 miles from 

 Warwick and the stone is entrained at Mt. Sturt railway 

 station. The stone appears to be quite good and in the 

 Parliamentary Report of 1888 it is very Avell spoken of. 



It has been used in the front of the Warwick Town Hall, 

 and the Old Railway Station, built in 1888 ; in the latter
