This iaestene has a handsome appearance, nod with proper treat- 
ment should make a good cement lime. 
The iron ore found in the red shales west of the town is very pure 
and excellent, as will be seen from the following analysis by Professor 
Wormley :

This is scarcely a hydrated sesquioxide or limonite, the percentage of
