100 building stones of queensland. 



Previous Literature. 



There has been \*ery little published with respect to 

 the subject of this paper. In 1888, Parliament appointed 

 -a Select Committee to report on the Sandstone Quarries 

 of the Southern District. The rej)ort is to be found in Votes 

 and Proceedings, iii, 1888, pp. 1021—1044. it shows that 

 the matter was very closely investigated and quarries in the 

 Warwick, Highfields, Murphy's Creek, Helidon, (Irand- 

 chester, Brisbane, Logan Village and Beaudesert disti'icts 

 were inspected and a great deal of evidence collected. 



Generally speaking the views offered in evidence as to 

 the respective \alues of the different stones ha%"e been 

 borne out by the weathering in the buildings. 



In 1905, Mr. L. C. Ball, B.E., published an article in 

 the Government Mining Journal, -p. 457, on the Queensland 

 Stones for Architectural and Monumental Purposes. The 

 article is quite a brief one and while mention is made of the 

 important granites and mar1)les the section on sandstones 

 is rather incomplete. In the prc\ious year, in Publication 

 194 of the Geological 8ur\ey, Mr. Ball dealt revy fully with 

 the limestones and marbles of the Central District, gi\"ing 

 full descrijitions of the fine marble deposits in the Duke 

 C^roup of the Northumberland Islands, between Rockhamp- 

 ton and Mackay, rdso of the nuir'bles in the Calliope r.rea, 

 near Gladstone. 



In 1911 a paper by the writer on the Building Stones 

 of St. John's Cathedral was published by the Royal Society 

 of Queensland in its Proceedings. 



The Queensland Mineral Index by B. Dunstan, F.(i.S. 

 contains references to limestones and marbles.
