Cement Mining in Placer County.
MEssns EDiroEs: You have asked me for
some joIings with regard to the gravel claims,
since my return from the interior. AS the
Yuba and Nevada county claims have been
pretty well ventilated, herewith give YOU
some items from range of claims at Forest
Hill, Placer county, which the pubic knows
but little about. Why these rich claims
should not be better and more generally
knowu, | don't understand. unless the own
crs thereof have done SO we'll that they prefer
to keep shady to avoid the inquisl've tax
collectors.

The tunnel in this claim is 800 feet lung,

This claim was worked with hydraulic pipes
and am confident that $4,000 600 was
wasted in getting the $2O00,000. The
American River, nst below there, in its rich

Immense waste from these claims.

claims in Fores, Hill, covering an area OF

or broad. Statistics show yield from the

draulics, of abon, S.. 600. .O00-or aniaverage
Of about S5O0,00O from each claim. Had
this dirt been worked by mil process, twouid
unqueslionably have produced $4,000 600
! instead OF nine millions If dollars. A large
propotion OF this dirt that will not pay 10y
washing, will pay we'll by milling. owing to
its being SO hard that il does not slack MOI
break up. even when it passes through sever

it viii pay equally as we'll whether it be hard
or soft. These recently erected mills will
soon demonstrate all this.
