tlties.
Mr.. Clarence King, the eminent geol)-
gist OF national fame. who formerly had
charge Of the Richmond mine. and is quite
familiar with the physical condition OF
Ruby Hill and the manner OF the deposi-
tion OF the ore bodies, has expressed the
opinion in the most indubitable manner,
that exploration should be carried to fur
ther depth OF 900 feet or theresbout, and
that there is no geological reason why ore
should not be found in as valuable guam
titles a. il was found above, IL the work
were done. He thought that gold bearing
arsenical pyrites and silver -besring
gslena would be found In more compact
form, and hence richer than the oxidized
ores, which were more or less mixed with
limestone, that the lode had yielded above
IL is calculated that the subterranesn
disturbance which created the Rnby Hill
fault raised the footwall side OF the Pros.
pect Mountain limestone. through the Eu.
reka Con. mine, about 1400 feet.
PROSPECT MOUNTAIN
Rises TO an elevation considerably higher
than that OF Ruby Hill. showing that the
erosion OF the latter locality must have
greatly exceeded that of the former. Pros.
pect Peak, the highest point on Prospec.
Mountain, has an elevation of 8. .6O4 feet,
and the bjghest point on Rnby Hill reaches
an altitude OF only 7. 29l feet above sea
level. ,is here seen that the difference

accounted for in the excessive erosion OF
