That copper has been of frequent occurrence in this quarry is proved not 

 only by the debris of the workings of later years,, but also by the fact, that it 

 is still to be found adhering to the stones in many of the oldest walls about 

 Newton Kyme, the materials of which were taken out of this quarry. 



At a small village called Farnham, about two miles north-west of Knares- 

 borough, which is also upon the magnesian limestone, a considerable quantity 

 of copper was formerly obtained by means of galleries worked through the 

 limestone. 



The copper, which appears to have been the green carbonate, was not only 

 found investing the limestone, but also in small masses, seldom exceeding the 

 size of a large potatoe. 



The workings were abandoned, and the shafts (which were generally about 

 15 or 16 yards deep) filled up, in consequence of the great accumulation of 

 water, which they ineffectually attempted to overcome by engines worked by 

 horses ; the disputes among the proprietors of the adjoining lands preventing 

 them from driving a level to take away the water. 



A small quantity was found so late as twenty years since, upon sinking a 

 well through the limestone. None is ever found in the quarries now worked 

 at Farnham. 



These two are the only instances, 1 believe, where any of the ores of cop- 

 per have been found occurring in the magnesian limestone of this country, 

 and they appear to have escaped the notice of Geologists.
