THE SLATE ON STONEHOUSE HILL. 
As connected with ‘my subject, in a Geological 
point of view, I hope i shall be excused in re- 
questing, in this place, the attention of my readers, 
to a remarkable interruption of the regular stratum 
of Limestone, close by the North side of the road. 
leading over the Hill, from the Iron Foundry at 
Mill-Bay, to Stonehouse. A portion of the clay-slate, 
for several yards in breadth, protrudes itself up- 
wards, amidst the Lime; the layers of which are 
most curiously curved, and bent out of their ‘regular, 
and, apparently original line, and appear as. if they 
had been disturbed in their natural position, and 
forced upwards by some violent convulsion. —
