access 10 the main road and unlimited
dump room. From the east nvino re-

secting our shaft at q depth Of Gu feet
from the surface, which We intend to
use A n drain tunnel when We resume
pumping. Our shaft, which has three
compartments Of the usual size, has
been sunk and timbered 10 q depth oil

Va decided 10 introduce the same style
of engine and pumps N those adopted
by Mr.. Fair on behalf OF the California
mine. and made q contract at c with
the Union Iron Works for duplicates OF
tho same in every respect, also engaging
Mr. Patton. the able engineer OF the
Consolidated Virginia and California
mines. to supcrintend their erection.
The style OF engine vas q wide depart

lead. but its success Is now Established
beyond a doubt BY aetuai working test
