Is irrelevant and immaterial, q besides il is
asuoIect upon which great deal of testimony
mas already been introduced and do not intend Il
the testimony that has already been pu.
| in on that subject
Inc Court-ni 1t is connned to the American river,
| suppose there is no objection
| Mr.. Hart-They have proven the number N,
| stamps by two or three witnesses-4OO s,anIs
Mr. Becher-Something more than the American
| river is involved in this controversy They have
shown the filing in the American river and in tbs
| Sacramento river, and in Suisun bay, and In San
| Pablo bay. and in San Francisco BAY and they do
not claim that the American liver has done ali the
| filling, but that it came from the American river
| only in part.
The Court-You wish to show what other sources
have contributed to the filling of Suisun bay.
Mr. Hart-I think that is material, but We dosnot
| intend 10 offer any witnesses on the subject OF
| quartz mines and stamps in California and the
| American and other rivers.
Mr.. Belcher-Well, the American river then, and
not elsewhere.
Mr. Hart-I object to this witness testifyiug as to
the number OF stamps on the American river. or
the ground that it is cumulative and we do not in
tend to controvert the testimony already in.
The Court-It does not seem to be confined to
that.
Mr. Belcher-I think it comes in bad grace to OBJ.
ject, when we had so much cumulative evidence on
the other side which was received without objec-
tions
Mr.. Hsrt-We did not know what you were going
TO contToyert.
Mr. Belcher--I ask the question generally.
The Court-Go on.
Mr.. Belcher-Q.-As to the number Of stamps in
1862?
A-The number of stamps iu 1862 was something
over 600.
Mr.. Hart-In the State7
AIN the State. At the present time there are
not less than 2720, Of which $50 engaged in the
crushing Of cement.
.. What is the average stamp duty?
Alt will vary all the way from ton and q
quarter TO three and a half TONS depending upon
the Wpipht of tho nd tha ebara eta NJ he
material they have to crush think that they will
average not less than two tons to the stamp.
Mr.. Hart-That is quartz
Ayes, quartz.
Q.-what is the average duty of those engaged
upon gravel7
A.-They crush all the way from two and half
to six tons to the stamp. would set down the
average at about four tons to the stamp.
Q.-What is the character Of the material passing
from the quartz
A-That is finely pulverized material, which
passes through what we call no gauge It will
generally pass through sieve Of about forty holes
to line inch, making forty times forty. That
would be the number of pieces that would 20
through an inch square. 1t is fine powder.
Q.-And how about the size o! the material pass
ing throush-the gravel.
At varies from one eighth of an inch 10

The large portion Of il is pulverized to mpalpa
bic powder, but that u the size Of the screens in

teria has TO pass. 1t carries in size from eighth

screeu so that in the pulverzation anything that is
small enough to pass through quarter OF an eighth

the crushing very large portion is crushed 10 iu-

Q.-The computations have besn for the most part
here maze in yards. VIII you give il so that we can
convert tons into yards-give the relltion which
they bear to one anOthcr7
A mill crushing quartz, soy We have $500

Of quartz will reduce somewhere in the neighbo.
hood Of 5000 tons day.
Mr.. Belcher-Q.-And that reduced to yards, how
much would it her
Alive thousand tons. Twill put IL by the year
They take out in 800 days million and half OF
tons. That would be abou. million Of cubic yards
Q-That Is to say, ton and a half is equal TO a
yardf
A.-The 5000 tons day, say they crush 800 days
IN a year. will Yield one million aud a half tons
Each ton and half is, in round Dumbers, about
cubic yard, that it would be the equivalent Of
reducing 10 powder about equal to million cubic
yards year.
Q-Is this million Of cubic yards which comes
out in fine sand
Am find sands and slime.
Mr.. Hart-This million cubic yards per year is the
total amount Of their 2 GOO quartz-stampsr
A.-Yes
Q.-Al the quartz stamps in the State
A.-Yes.
Mr.. Belcher-Q.-How rany feet of broken rock
makes n tOnl
A.-Thirteen Of quartz.
Q.-B.o oxen?
A Unbroken in place IN the vein thirteen, and
broken twenty. Quartz in place in the vein, th-r
teen cubic feet s the equivalent of 1900 pounds I;
broken and ol the dump, not crushed, il will take
twenty cubic feet to make ton
4Q.-That is the measure that is recognized every
where?
A.-Yes that is formula by which we estimate it.
Q.-Eot only by miners, but among engneersf
A.-Yes
Q-No8 do you know of any quartz mines, and
ii you do, name OF the largest quartz mines and
its production.
A.-The largest quartz mine in the State is the
Sierra Buttes, in Sierra county. One company in
Pumas county crushes Oh an average about 120, 600
tons year.
y, Q.-How many cubic yards?
A-Nearly 100 coo cubic yards not quite If
there had been 10000 tons it would be Just 100000
Q-It has been stated by witnesses here that 60O,-
600 yards was the amount worked by the defendant
here from its mines in year. Will ask you if you
know the character Of the material worked there
A.-Yes sir. visited TIE mine on November
10Th the last time Last year.
Q.-From what you have seen there state how, IN
your judgment, the rivers would be effected by the
amount ef material washed from that n.ine and
from the Sierra Buttes.
Mr. Hart-we object to the question until the
witness has shown himself competent to estimate it,
Mr.. Becher-We will pass the question for the
present.

mining.
Al have been connected with drift mining in
FL Dorado county, and largely interested in that
property, where have several drift mines at work
| have examined very large number OF drift mines
in various portions Of tho State, more particularly
in Sierra county. know OF several mines in Placer
county.
2.-pq you know the Bald Mountain mine'
Q.-state as to the amount r moved from that
mine?
Mr.. Hart-where is the Bald Mountain 3?
An Sierra county, Allegheny
Mr.. Belcher-Q-State the amount removed from
that mine, from 1872 to 1880?
A-Duriug six years, $50, coo carloads-that is a
drift mine. These carioads measured about a cubic
yard SO that it would be approximately $50, 600
cubic yards In one year they removed as much as
log 600 cubic yards. Some weeks it has emouuted
TO 5000. Some days the amount is very ! rye The
material distracted from that mine is fine cement
and gravel 1t is brought out, and the cobblestones
and the larger rocks are left behind in the mine
This material is brought out and placed on dump
Q-Now, how will this character Of mining
the drift and the quartz miniug-compare with the
drift gravel mining or blue gravel mining; or say
with the defendants mining IS to the comparative
amount Of material that will be moved or carried
away from the dump by water?
A In the of the quartz and the gravel that
is crushed, it being reduced to mpalpable
powder and sand, why it will be transported down
just far the water has sufficient power carry
| it. From the drift mining q much larger proper
ton, of course will be washed into the rivers In
fact, the greater portion OF it will be washed away
down, from the fact that it is reduced to smaller
pieces than in the hydraulic mining cllled. A
larger proportion Of the material coming from the
| drift mines will be carried away into the lower
channels of the river than will be of that removed
| by the process Of hydraulic mining so called.
Q.-State approximately If you can, or If you
know, the extent Of drift mining in the State?
A.-Well, it is carried on to a very large extent.
| In Sierra county for many years the miners have
| engaged in this kind of business little farther
north, believe, little way from Bald Mountain is
| another nline called the Bonanza mine, where they
| are employing some 100 at the present time.
They brin5 ing out fir 200 to 800 tons per Jay
| OF material. Down towards San Luis and Laporte
| there are a large number Of miners at work this
kind OF mining. These are in Sierra county. There
are others IN Plumas an Butte ceunties-in fact,
nearly every mining county. In Placer county there
| is very considerable amount Of this kind Of mining
| DONE both on the North Fork and Middle Fork Of
| the American river. Both these classes OF mining
| u=e water.
o.-what percentage Of all the gold produced in
the world has from hydraulic mimi g, or been
| produced from that process Of mining?
| Objected to as irrelevant and immaterial.
The Court do not any materiality in 1t.
Mr. Belcher-We offer to prove by this witness,
and expect him to testify il allowed, that at least 95
per cent of all the gold in the world has been pro-
| duced by the process known as hydraulic.
| The Court-You mean by washing sand and
| gravel?
| Mr.. Belcher- Yes.
Court sustained the objection and counsel for de-
| fense excepted.
Q-Have you given special attention to the mines
