English: Limestone seams, Kilsyth Hills In the First Statistical Account of Scotland [No. XI. Kilsyth parish] written in about 1793 the minister, the Rev. Robert Rennie records of this place.

"In a variety of other places, there are favourable appearances of lime;

at a farm called Berry-hill, there are several strata of lime, which  
have been wrought to advantage. But it is much more sandy, and contains  
less calcareous earth, and is, in every respect, of a courser quality.  
Yet, as there is a good roof, and, as it may at all times be wrought  
level free; as it consists of several strata, of above 6 or 8 inches  
thick; with interstices of clay about the same thickness; and as it is  
divided into small square wedges by perpendicular fissures, it is  
wrought with ease and little expence; seldom or never requiring the  
force of powder. But the road to it is steep, and in bad repair;  
therefore demand for it has not been great, except for the immediate  
neighbourhood.
I suppose however, that there may be at least 1500, if not 1800 chalders   annually thrown out from the three posts put together."
