The fact that there is so much variation in sedi- 

 mentary stones is not at all appreciated and the utmost 

 discrimination should be made in, first of all selecting 

 the quarry, and then in seeing that the stone put into 

 the structure is carefully selected by a thoroughly competent 

 jjerson, otherwise the results are extremely likely to be 

 unfortunate. 



Among other places this stone has been used in the upper 

 story of the Commercial Banking Co. of Sydney (1866), 

 in the old building of the General Post Office (1871-74), 

 the facings of St. Stephen's Cathedral (1874), the base 

 course of the Roma Street Railway Station (1875), the 

 facings of St. Paul's Presbyterian Church in Leichhardt 

 Street. It was used to a large extent in what is now the 

 Deanery at St. John's Cathedral, but which was erected as a 

 residence for Dr. Hobbs. This building is well over 50 years 

 old and the stone has weathered very well. The 

 Australian Bank of Commerce was constructed of the stone 

 and it was also used in the Caretaker's Lodge and fence for 

 the Supreme Court, the base course of the present Tourist 

 Bureau and Geological Survey Office. The manner in which 

 the stone frets away when allowed to become moist is well 

 seen at the Tourist Bureau and Geological Survej' Office. 



Goodna Sandstone. 



Some of the best sandstone which has been used in 

 Brisbane came from Goodna. 



The largest quarry and hat producing the best stone 

 was Jeay's quarry, which is within the grounds of the 

 Woogaroo Asylum. The quarry is in the Bundamba sand- 

 stone and was Avorked chiefly from 1860-70, after which the 

 Breakfast Creek stone began to come to the fore. This 

 quarry supplied the stone for the old Government House 

 (University) (1860-C2), the Brisbane Town Hall (1864) 

 above the first cornice, and Parliament House (1865-7) 

 except the colonnades facing George Street and Alice Street 

 {see text-figs 14, 16). 



The sandstone is one of medium grain and has a fels- 

 pathic or argillaceous cement. The average grain-size is 

 .25 mm. The grain-size is rather irregular and the particles 

 are angular to subangular. The cementing medium is
