management in one of the largest coal
mining enter prises on the Pacific Coast,
that OF the San joaquin and San Francisco
Coal Company, whose extensive deposits
near Livermore are generally known as
the Corral Hollow mines.
Up to three weeks ago John Treadwell,
who developed the now famous Treadwell
mine in Alaska, and who was one of the
two original owners of the Corral Hollow
properly, was in charge OF the mine, but
owing to difference of opinion among
those heavily interested in the corpora
ton as to the efficacy of the methods EN-
ployed it was dec ded to make change,
and Mr.. Tread we'll resigned.
F. J. Horswiil, who has made coal min
ing life study and who developed num-
Der of he largest mines on the coast, has
succeeded Mr.. Treadwell and it is ex-
pected that an immense increase in the
output of the mine will soon take place.
The real cause of the change as ex-
planned by one OF the principal officers is
that the directors or at least q portion of
them believed that while Mr.. Treadwell
was a practical and competent quartz
miner he had not grasped the situation at
Cor raj Hollow sufficiently to place the
vast business on paying basis and that it
was necessasy 10 have a practical coal
m iner IN charge in order to make the
m inc pay interest on 81, S72 600, the i'm
mense sum already spent in developing.
Manaler Horswill went to the mine
three weeks ago and after spending that
period of time in investigating, made his
first report yesterday TO the directors, the
result iustifying the confidence of those
who have invested their fortunes in the
enterprise.
Mr.. Horswill, who has been coal mining
thirtv-two years, was the locator of the
great Car bon Hill mine near Tacoma and
has also been connected with the Coos Bay,
Mount Dlablo and other well-known
mines He made an expert report on the
coal deposits of Alaska for prominent capi-
talists, who contem plated investing there.
Mr.. Horswlll has recommended that the
system of mining at Corral Hollow be en-
tirely changed, and that instead of the
'tlong- walr' method the "breast and
pillar" system be employed. This does
away with the dead work necessary in
running tunnel along beside The vein,
and vastly cheapens the cost of coal per
ton to the company. By the breast and
pillar" system the tunnel is run directly
into the coal and the miners throw out
the black diamonds OF commerce as they
delve into the bowels of the earth.

after the meeting, "and l can say that
alter weeks of careful study l believe that
the day is at hand when San F. ancisco
will be supplied with good coal at reason
able prices, and the idea disproved that
California cannot produce good Ignite
coal.

and pillar plan is the only one thatwill
work satisfactorily. 1t gives cheaper and
cleaner COAL The directors have adopted
my suggestion that the method be used,
and the Ito men now at the mine will be-
gin going down into solid coal at once.
Il have made a study OF the situation
at the Summit vein, which is seven feet in
width, and find it to be composed of as
clean and hard coal as there is on the
coast. A force OF men Is already at work
opening the tunnel so as to admit of the
use of an electric locomotive in bringing
the coal out. The Eureka vein, eleven
feet wide, is also being worked.
"Within three months from now | ex-
pect to be extracting 500 tons per day, and
within six months to be taking out 1000 to
1900 tons per day.
"The coal is superior grade OF Ignite
and will compare favorably with Beaver
Hill, Seattle, Coos Bay or any of the coast
Goals.
Estimates have been made that there
are 20 600, 900 tons of coal in sight, and
do not think that this is an exaggeration.
The coal runs in what we call pitch veins
that are so situated that the product can
be economically mined. When we get far

will not cost moro than sixty cents a ton

half miles long by one and quarter miles
wide, there are seven veins ranging from

The company was incorporated on Feb
ruary 81. 1895, With a capital stock of
S5, ,O0O, 600. Before its incorporation over
$500. 600 had been expended on the prop
erty by James Treadwel and John Tread
well, the original owners. The company
also owns all the stock OF the Alameda
and San Joaquin Railroad Company,
which was incorporated for the purpose
OF constructing railroad from the mines
at Corral Hollow to Stockton, a distance
of thirty-six miles. This railroad is now
running, equipped with locomotives and
rolling stock, and owns valuable water
front property in Stockton. costing more
than Sl00000. In all about $500 Oc0 has
been expended in the construction ana
equipment of the railroad and in the
acquisition of property.
II. J. Small, an expert employed by the
Southern Pacific Company TO test the coal
with view OF using it in the locomotives
of the company. reported in April, 1898,
that ''The result of the test shows conciu-
sively that the Treadwell coal is entirely
satisfactory for locomotive use."
III. L. Stevenson. II. Stillman and other
EN- ployes OF the railroad made reports OF

from Carbon Hill for the use Of the COM
pany.
In run of $40 miles less water and also
less coal were used, and the steam pressure
was greater in the engine burning Corral
Hollow coal than in that burning Carl
Hill coal, ana under similar conditions
he tests were emine ntly favorable to the
product of the Livermore mine.
