to some extent .stained with limonite. There is not such an 

 abundance of it as in the Breakfast Creek stone (see micro- 

 photograph 5, plate VIII) . In colour it is rather a light pink 

 or light brown, often arranged in concentric bands. The 

 ajipearance is warm and not so harsh as that of the Murphy's 

 Creek .sandstone or the white Helidon sandstone, although 

 it is not as warm as the brown Helidon stone. 



The excellent weathering properties of this stone may 

 be noted on examining the buildings mentioned, Parlia- 

 ment House especially. Where the stone has been 

 alloAved to become moist it has fretted awa}', but 

 any sand.stone v,-ith an argillaceous or clay cement.

which this stone has, would fret in a similar manner. 

 This is especially the case around the base course of 

 the Uni^■ersity or old Government House. The smooth- 

 dressed stones used as kerbing stones around the verandahs 

 have exfoliated badly, also the columns ha\e lost their 

 flanges near the base. Where the stones have not been_ 

 habitually moist they have weathered in an excellent manner 

 and one cannot help being impressed by the fresh, clean 

 appearance of the stone. The stone does not become 

 dirtv. as do some .'^tones which are no harder.
