The clays associated with the coal-seams were tested at the Abbotsford 

 Tileries, and found not to withstand a sufficiently high temperature to be 

 called fireclay. 



Other Materials of Economic Value. 



The Burnside marl-pit was opened in 1903, and works were erected 

 near by. An attempt to produce an hydraulic cement proved unsuccessful. 

 The Milburn Lime and Cement Company now use the marl from this pit 

 to mix with the lime from Milburn to form a cement. 



The limestone of Brighton was burnt many years ago for its lime, but 

 the rock proved to be of too low a grade. 



The greensand contains constituents that have value as fertilizers 

 (Ries, 1905, pp. 155-56), but the thickness of the deposit near Green Island 

 is not sufficiently great to warrant mining.
