FIFTEENTH DAY OF TIE sLIcKENs
CASE IN COURT.
cross-Examination of G. F. Allardt-Testi
mony Of D. B. Huntley, Metallurgist,
and C. 3. Cosby, Civil Engineer.

The slickens case-The People vs. Gold
| Run Ditch and Mining Company-was re
sumed yesterday at 9:30 a. H., in Department
Two of the Superior Court, Hon. Jackson
Temple presiding.
Direct examination of G. F. Ailardt Ito
Mr.. Cadwalader)-There are no other nv.
draulic mines excepting those have described
that tail into the North Fork. [Witness was
asked to identify mapl This is sketch
made by me on the 18th of November, 1881,
representing the American river from Smiths
gardens to its mouth. On the south bank the
figures denote the hight of the bank and the
depth of sediment. The rest of the map is
self-explanatory.
Cross-examination (by w. c. Belcher)-I
measured the water in the upper or north
claim of the Gold Run mine in the fume.
There was about l, 100 inches of water at that
time being used in that mine. The sample of
water I brought into Court was dipped from
the surface of the water at the mouth of the
iume. could not tell the amount Of stone
beiGg carried through the hume I could not
see them, but could hear them. In ariver the
surface water does not carry as much detritus
as the water near the bottom. I took
samples OF tine water at the mouth of the
fume several times. I think that the man.
ner in which I dipped the water out was 4
fair test. Here witness explained how he took
the sample from,the hume. There are several
kinds of analysis, chemical and mechanical.
My analysis OF the water I should call a
mechanical analysis. One of the rules of
Depucet is that water moving with a current
Of one-sixth of mile will move light mate
rial substances.
Mr.. Belcher-You say yeu measured the
depth of the river by your horse. Did you
also measure the length of the river by your
horse?
Witness-Yes. sir. I measured distance
from point to point by timing my horse

my horse was mustang or not. am not

mining done in that neighborhood that I
would class as hydraulic mining. 1 walked

with cobbles. [ saw q portion of an old tun.

The mining bank at this point was about ten

river at Texas Hill was thirty or forty feet
deep, and small portion of the surface had
been washed off. Imade no estimate of the ex-

river, and was witness in the Keyes case.
My surveys of the Yuba, Feather and Bear
rivers were made at the request of Mr.. Cad.

Mr.. Sexton, of Marysville. Mr.. Sexton was
the Secretary of the Anti-Debris Associa-
ton. The American river from the mouth

very rapid stream. Here witness was asked
for the reading of the barometer at various
points on the river between Gold Run and
Folsom. The barometer showed the eleva-
ton at Folsom to be 100 feet, Carrolton's
$40. and Lyons Bridge 80.

DWIGHT B. HUNTLEY
Sworn Ito Mr.. Cadwalader)-I reside in Oak
land, and my business is that of metallurgist.
took mining course and graduated from
the University Of California in 1875. Since
that time have been engaged in Mining con-
siderably. / have been engaged in my profess
sion in Nevada county, Arizona and Utah.
l visited the Gold Run mines with MIR.
Allardt last month. 1 am somewhat familiar
with hydraulic mines. l resided for sixteen
years, when boy, in Grass Valley. We left
Sacramento for Gold Run on the S0th of
October, and returned on the 7th of November.
We travelled in the channel, and along the
banks OF the river, from Folsom to Gold Run.
At the Gold Run mine saw Mr.. Gould, Mr.
Pierson, Mr.. Grunsky and General Cosby
Mr.. Grunsky was at that time engaged in
making an instrumental survey of the pit.
The pit is very irregular. The banks vary
in hight, and perhaps would average 120 feet.
The banks surrounding that pit by miners
would be called gravels It has blush color,
raA to -, T. kk.r
ular masses of sand, from three inches to
three or four feet thick. The gravel con-
tains considerable sand and clay. You can
see cobbles sticking in the bank. Some of
the cobbles are half as large as mans head,
and many small ones. The clay in the mine is
called pipe-clay. When first exposed it is very
tough; after being exposed for some time
to the air, it slacks, crumble, and works
readily. should judge that one-half of the
material Of the mine is small cobble, above
the size of pea, and the other half would be
of a finer material. The bottom gravel has
blush, greenish color. The upper gravel
has reddish color. Here witness in a
very scientific manner explained the different
colors of the banks. and the causes which
produced them. There are two strata of

the pit this mine is very clean. On the east
