 Mrs Clark, along the highway to Le Roy. It has long been known

 limestone known locally as "bull-head" and belonging to the strata 

 immediately above the Lockport dolomite. Above this broad base 

 is a narrowed mass of laminated hydraulic limestone which is capped 

 by an expanded block of more compact material, the whole con- 

 stituting a section of the Bertie waterlime, taking on a roughly 

 hour-glass shape, having a height of about 30 feet. This Silurian
