182 Henry C. RichdnU: 



xA. perusal of the tables shows that the stones with the best 

 weathering properties are the most resistant to compression, 

 and that probably the poorest building stone in the list— viz., 

 the Darley, also has the lowest compression value. 



The Stawell stone gives remarkably high results, exceeding 

 those of many granites. The Apollo Bay stone gives a good 

 value, and this seems quite in keeping with its resistance to 

 weathering. The Sydney stone comes next, with the Dunkeld a 

 little below it. 



Tlie Barrabool Hills stone gives a low value, and from the 

 manner in which it weathers can be considered only a fair 

 stone. With regard to both the Bacchus Marsh and Darley 

 stones, both give very low values, quite consistent with their 

 durability, as seen in Bacchus Marsh and in Melbourne. 



The fine-grained Egerton stone value is fair, and from what 

 is known the stone weathers well. The other values are low, 

 but nothing is known of their weathering properties in build- 

 ings.
