for building purposes. The most important are in Panton
and neighborhood, from which are taken the beautiful building stone
much used in Vergennes ; and a quarry of excellent dark blue stone
in the south part of Cornwall, in convenient layers for building,
with a handsome natural fiice. which was used for the front of the
College Chapel,and for underpinning of many other buildings in Mid-

building stone.

places west of the lake, in order to manufacture it economically.
About a mile north of the ore bed, on the east side of a ridge
