Sacramento daily record-union., 1882-01-18
Island in the Caribbean sea. Went from tn

island in the Caribbean sea. Went from the
mines to San Fiaucisco in 1850. Was there
till 1868. From 1S49 to 1860 was engaged in
instrumental surveying in Suisun valley, then
came to Sacramento and went into the lutn-
ber business in 1902. Began on the
hank of the river, between and * streets,
and after that on Front street, between n
and o. In 1858 moved to Front and n /;
1854 went to San Francisco and went into
the lumber business. The vegetable business
l ran was earlier; it was my initial. When
l went to San Francisco l was also engaged
in quartz business in Amador county. In
1856 removed to Amador village. Was there
till 1850, engaged with the Spring Hill, Max
i'm & Randall and the Keystone mine, and
also did surveying there. Studied and taught
engineering. chemistry, algebra, geology and
the principles Of mechanics before | came to
California. Was Principal of the academy
at Westerly, r. l., preparing young men for
college. For the last eight or ten years have
been surveying and engineering. Came up here
in October, 1881, for the Miners Association.
MIR. Smith engaged me in November to make
q reconnaissance and report. Began work Oc-
tober 6sh. On the 7th went to Folsom ar
rived there that evening. The next day came
back to Alder crack. From Folsom went TO
Placerville by road went up IN one Gay.
Next day made reconnaissance OF the country
about Placerville; went to the mills and the
gravel mines, etc. Didn't get over hve miles
from Placerville. Staid at Placervllle that
uight. Was in Placerville on the 10th and
1lth; left on the 18th and went TO George-
town thence TO Forest Hill, Michigan Bluff,
Iowa Hill and Gold Run. Was in the Gold
Run mine October 18th; spent part OF the
day in the mine was in its pit from two to
four hours. Mr.. Gould and Mr.. Skidmore
were with me the latter is secretary of the
Miners Association. He was with me all the
time from Folsom. Know what is called
blue gravel" This, in box 3. is not blue
gravel this, in box 2, is more like it. Ma
terial in box | may have seen in the mine.
a two-mile current, acting on such material,
would move considerable part of it, accord
ing TO De Buats tables, but he experimental
on smooth boards. He says mile and one
third velocity per hour will move pebbles an
inch in diameter. This in box 2, according to De
Buat's tables, two-mile current would move
on a smooth board, but in rough river bed
it would pack. 1t would move it on smooth
bed rock. If LIE Conte goes by the sixth
power, he has not adopted De Buat's tables
The moving power OF water is not treated of
in any geology of which 1 have knowledge.
Question-The material in this blue ce.
ment No. II mas powders or soli1 material
in it; now estimate the current necessary TO
move the cobbles, etc.
Answer-At a mere estimate, I'd say
four-mile current under Du Buat's condi-
tions, calling these materials pinch. Have
never read LIE Conte's tables as to the trans
porting power of water. Saw material in
the bank CT the Gold Run mine resembling
this cemented mass here (holding the Pinch
cobbles) and above saw material resembling
this lin box y, Found blue cement at the
depth of forty or fifty feet. The cementing
material in this blue ceuentsd mass has in it
iron. clay, sand, etc. The proportion of sand
and clay in box 5. as compared to solid rock,
is very small, but there IS more in box 2. and
in this blue cemented mass about one-third
is fine cement, sand and pebbles and two
thirds of the cobble character. Some part
Of this material would be transported by
Whoever says that the six-power formula is
true in practice is not correct. An
eight-mile current viii not move a
cobble of half q cubic foot. An
eight-mile current would move, according to
De Buat, q rubble-stone containing S64 cubic
inches, or half cubic foot.
Q.-We are dealing, not with quarry rub
BILE, but water-worn stones. Ii river bed
is graded SO that railroad could be laid on
it without cutting or filling, what sized cob
bles would an eight statute mile current move?
Alt would carry one containing 1,200
cubic inches, or little less than IL inches
each way; that is. on smooth bottom.
Q.-Now double that current?
A.-That would probably carry one about
twelve times as large, or about % inches each
way. This is approximate. Don't know that
LIE Conte says such current will move stones
twenty times as large. The Mississippi has
not SO strong current as the American.
Don't think it has three-mile current. With
o three-mile current water will carry ma
terial of l 10 specific gravity in suspension
think it would not carry sand (No. 6) like
this. In food time the river might throw up
such material; boil it up on to its banks. a
mile current would move it on the bottom,
but not carry it in suspension. Witness was
here examined at great length as to the
origin, constituent parts, etc., of mica, alu-
nina, slate, granite, etc., and further as to
the velocity of streams and the formulas of
De Buat and others also as to what slick
ems is, and its general character. Witness
was shown blush csmented mass ard said
he discovered trace Of mica in it. II the
sample came from the Gold Run mine,
that came from there. Saw nothing
in the Gold Run mine that contained vege-
table mold, or what in the general sense
would be understood to be manure. On that
in the bays don't know that
the return route was only 1000 feet or yards
from the up route. Witness was several times
asked If two-Inile current would move a
given body, if a four-rlile current would not
move body sixty-four times as grsas, and
each time replied no.
Recess.
