X K; am familiar with tho workings in these
mines; the underground workings from the
Lawton shaft to tho X X disclose bodies Of
ore; tho I'd level of the X X shaft runs in
ncarly an eastsrly direction; on that level |
find indications of . vein; there has been q
large body Of ore worked out near tho line OF
the Phenix ground: there Is a quartzite wall
underlying the ore exposed in the I'd level a
distance Of $50 IT,; tho face Of this foot wall
in tina X X. as well as the Eureka CONSOLE
dated, is generally smooth on that lev.l; con-
adorable of the footwall is exposed on tho
Sd level; we find it wherever We put in a
cross-cut; / found it on all tho levels down to
