TEMESCAL TIN.

TEMESCAL lin.
For many years it has been well
known fact, hereabouts, that there ex-
lists in the Temescal caf1on, beyond
South Riverside, one of the finest veins
of tin ore in the world. Deposits of this
metal are very rare, and for 5000 years
Cornwall, England, has enjoyed
practical monopoly of the world. In
the days of the earliest history of the
world, Phenician merchants are known
to have traded with that country for this
metal. In the days of the Tudor
monarchs of England, and in those Of
the Plantagenets who preceded them,
large part of revenue Of. the English
crown was derived from these mines.
Since the discovery OF America little tin
has ever been dug on this continent.
The deposit in the Temescal mountains
is perhaps the best in this country.
The San Jacinto Rancho formerly
contained 4S,946 acres. Part of this
tract has been sold off and there now
remains of the grant in one lump As, ,126
acres. All of this has been purchased
recently by an English syndicate in
corporated as the San Jacinto Estate
(limited) of4London. In the director
ate of this corporation are such men as
Lieutenant-G General Sir John Stokes,
a vice-president in the Suez canal
company J. X. Francis, OF Richard
son q Co, Swansea; +. Har-
rington of Harrington & Co.,
metal merchants, Liverpool; N.
J. West, OF Harvey & Co., Cimited) of
Cornwall; Hon. Hallyburton G. Camp
bell, and Herman Gwinner, managing
director OF the International Bank of
London. The resident director of the
Company in California is Colonel E. N.
Robinson, late of San Francisco, but
now of Los Angeles, having rented the
Potter residence on Pearl street, between
Seventh and Eighth streets.
The capital stock of this company is
divided into 500, 900 shares OF the value
of s1 each, and 1000 Founders shares
of the value of G5 each, the
total capitalization being, in our
currency, 50, ,525, 900. Debentures bear
ing s per cent. interest have
been issued, payable in five years to the
amount of $625, 900. The San Jacinto
Tin Mining company were paid $350,000
for the property and it is the intention
of the new purchasers to spend $500, ,00C
at once to place their buy on produc-
tive basis. 1t is to attend to this deveE
opment work that Colonel Robinson has
come to Los Angeles. He has spent
much time already in making himself
acquainted with the property, and he
knows all there can be learned from the
surface of the ground.
The estate is valuable outside of the
deposits of tin known to exist there.
The $4,000 acres of land will support a
colony of people capable OF working the
mines, and what will be done in the
way of working the vein of ore and in
the way of improving the farming lands
will result in a very great enterprise in
this section.
Colonel Robinson estimates that %
square miles OF the estate are rich in
tin ore. He has traced 60 parallel
lodes through this area. He has located
800 or 700 other mineral deposits.
The mines OF Cornwall employ in one
way or another 900 people. The ore
in that district yields less than 21a pei
cent of tin. Many of the best metallur-
gists of this Coast and of England have
made assays OF the Temescal ore. In
all, as much as 10000 pounds OF it have
been smelted. The average yield OF tin
is 204 per cent, or eight times as much
as that of the mines of Cornwall.
The market for tin in this country is
very large. The imports aggregate
$40. 900 in value. California uses
$1,000 tons of tinplate a year and the
consumption is constantly increasing on
account of the development OF the fruit
and vegetable industry and the quanti-
ties of these products that are
canned. The same is true of all the
Pacific Coast. The salmon canning of
Oregon, Washington and Alaska de-
mand large supplies. The total con-
sumption of tinplate on the coast is as
much as 10000 tons.
The report OF this property made by
Colonel Robinson covers 81 pages royal
octave of closely printed matter. 1t
shows that there are gold, silver and
other ores in the mountains, and pre-
sents an exhaustive exhibit of all
the resources OF the property in a mas
terly manner. 1t was from these pages
the HERALD condensed the above facts,
after learning that Colonel Robinson was
on the ground and was about to begin
operations.
