In the last five years, and will be hereafter
worked out can be got down to Rice's bridge?
A--What material passes the Iowa Hill
dump might get down to Rice's bridge. |
should say that from one to two per cent. is
all that could pass there.
Q-How far is Rice's bridge from Sacra.
mento city, by the American river.
Alt Is seventy or seventy-fve miles-I
judge about seventy miles.
Q.-What is the character of the material
remaining in the mine with reference to the
character of the material that was washed
from the mine up to 1874 and 1876?
A-The material in the mine now has been
stripped Of the fine strata that originally ex
listed on top. 1t is the blue lead that remains
that portion that has the appearance Of the
original river bed-heavy. coarse material !;
and in the material remaining the predom-
mating character of the rock is slate. while
in the original bank that was washed off
from the top, quartz pebbles predominated.
1t was fiEe in character, containing good
deal of soil and immense strata of what
miners usually term pipe clay. Il is really
sand Just cemented enough so that when it
caves it breaks up Ia large masses. Instead
of pulverizing, it comes down in large blocks.
In the top there was stratum judged to be
30 feet thick of pure material of that kind.
1t is not strictly pipe-ciay, but is what is
known as pipe clay.
Q-How much more OF the top deposit
was transported by an inch of water than can
be transported by an inch of water of the bot
tom deposit?
Al know great deal more eould--iust
how much mere would be hard to tell.
I should say from three to four yards more.
This top material is moved by water much
eaeier than the bottom. And every hydraulic
miner knows that if ne has got hundred
yards Of this bottom material pulverized with
powder that he can work that off in q great
deal less time by mixing with it hundred
yards of the top material to run with it. You
can wash the 200 yards mixed easier than you
can wash the 100 of this bottom material
alone do it in less time with the same
head of water and the same grade
The present difference in altitude between
Bear river aud the North Fork at tire points
opposite Gold Run is more than LOCO feet.
The drifting process consists of excavatiug
those strata that contain pay and then wash
the gravel thus obtained The hydraulic
process washes away all the material of the
banks. Some of the drif5 mines employ
giants in the washing of the material driited.
The amount of displacement of rock. sand
and gravel by the miners prior to 1885 was
more than is being displaced to-day by the
miners in the blue gravel ct this time. 1
think the displacement was more then than
now. Since 1875 the number of yards dis.
placed by the miners has greatly diminished.
Ten tines as much was handled between 1850
aud 1865 as bas been handled since that tine.
The material washed prior to 1875 was OF a
much lighter character than that mined since.
The material from the blue gravel channels
remains at the DUMP, where it is depos-
tied. Those dumps remain to-day and viii
remain where they are now imbedded The
material in the rivera prior to the great food
OF 1862 was CT very light character and was
swept down to Sacramento by the high wa
ter. The rocky material now being depos.
tied will not come down with water, but il
finds permanent lodgmeUt. The principal
towns Of Placer county are Auburn, Colfax
and Dutch Flat [ have resided in Nevada
county fifteen years.
Q.-On what industry does the people of
Nevada county depend?
Mr.. Hart-I object. We are willing to ad-
mis that this is a great industry.
MIR. Dibble-You have shown, sir, that 100
farmers have been injured by debris, and we
wish to shew that 90. 900 people in Nevada
county alone would be ruined by the stop
page of mining.
Mr.. Hart insisted that as the prosecution
claimed that this was nuisance, it did not
make any difference whether the nuissnce
was committed by one man or y, GOO men.
Mr.. Dibble arose and Indignantly ex-
claimed, "The production Of gold has never
been nuisance %
The Court excluded the question.
