“Ist. The bed in question is situated in a bituminous shale, which, 
from ‘its own fossils, and from its connection with rocks, havin the 
fossils and other cubdasihienlte of the coal formation, belongs itself to 
that formation. 
“2d. The shale, for a considerable distance around the mine, exhibits 
great irregularities and contortions, caused by disturbances which have
