questionable whether tho clni on thu
north side Of tho limit ahUytiI named
can be- classified a. good marketable

The uvorlaying measures are about
100 feet thick hnd they are OF loose
irtgmuutary nature, anu contain no
solid formation suitable for building
purposes, but the underlying MEASURES,
IN cl0te proximity 10 the coal, contain
fiuo thin measure Of clay OF superior
quality and II II b this clay the agent
must look ~ the principal cause OF
the gfHduai upheavai ~ the floor Of
the entries anu r0Oiis Of the mines.
The mine, ATE opened from the eur.

OF open dIiits, levels or aiopos, anu the
mineral IL g0t on the Sillar and Stall
principle. The angle OF inclination
varies much-being greater at tho
south Than at the north limit, say from
degrees u. TO 20 degree T., aud the
center of the best coal IL at No. o sec.

quonoe OF this the thickness " tho

clean coal. Ten feet vi clean coal with
