140 BUILDING STONES OF QUEENSLAND. 



examples of the use of this stone. This structure, together 

 Mith the four mentioned abo^"e, probabl^'rejiresents the most 

 important in this stone. 



The Rosemount Hospital was built in 1855-56 of stone 

 from the OX'onnelltown quarry, but OAving to the perishing 

 of the mortar in 1890 it had to be considerabh* repaired. 



The base of the General Post Office (1871-74) is of this 

 stone and it has weathered ver}- well, much better than 

 the sandstone above it. The first three courses in the Roma 

 Street Station (1875) are of the Spring Hill tuff . The base 

 course of the Treasury- building is from the OConnelltown 

 quarr^'. Several large stones ha\e been used here, but they 

 have cracked rather badly in many cases. The stone has 

 been used in the base course of the additions to the Govern- 

 ment Printing Office (1912), and it was also used in the 

 abutments of Victoria Bridge (1894-97). It has also had a 

 very extensive use all about the metropolis for retaining 

 walls and in this respect it is of much greater value than the 

 Brisbane Schist. For cellar work. etc.. the stone has been 

 extensively used, but it is being rej^laced now by concrete 

 in this particular direction.

MARBLES AND LIMESTONES. 



Queensland has only quite recentl}- commenced to 

 exploit her marble and limestone for monumental 

 purj)oses. Hitherto her limestone deposits ha\e been used 

 for fluxing and lime-producing purposes only. 



Ulam Marble. 

 The discox'ery of a white marble at Ulam, some 25 miles 

 south of Rockhampton, has resulted in the Government 

 subsidising to the extent of £1,000 the company working 

 it, and it is to be hoped that the deposit opens up satis- 

 factorily. The marble which has been obtained is some- 

 what coarse but no coarser than much of the Sicilian and 

 Italian white marbles which are used for mural and staircase 

 purposes. All reasonable tests ^ith respect to working 

 and strength ha-ve been well stood by this marble. It is 

 to be hoped that this deposit develops in a satisfactory
