making available monazite, zircon,
ilmenlte, chromite, garniee and
cassiterlte. 1t was also found that
the magnetic contained in the black
sands of the Pacific slope constitutes
a greater supply of useful iron ore
than any other known available
source. 1t offers no obstacle to the
production of high-grade cast iron in
the electric furnace, and this iron
can even be decarbonized to a soft
steel of high quality. 1t has been
fshown that if the heavy sand which
Is now going to waste in the sluiees
OF California and Oregon were saved.
and it only two-thirds of the platinsm
therein contained Is recovered, the
total production OF that metal in tbs
two states named would exceed I05.-
O00 ounces per annum, worth about
1000. 600. Assays of small samples
of concentrates from different IocaIi
ties gave values per ton as follows:

The investigation has made it
evident that very considerable sup
plies of magnetic iron ore can be
obtained by magnetic concentration
at a low cost at various points on the
Pacific ocean beach, and occasionally
at the mouths of rivers in still waters,
and the cheapness with which elec-
trlcity can be supplied through the
utilization of the mountain streams
is prime factor In solving the qaes-
tlon of their recovery.
The report gives full description Of
metals in the black sands. and will
evidently point the way to COM
mercial success in the treatment of
the vast mass of what Is now only
waste material. but which is rich in
some of the metals most useful to
man. 1t will give an impulse to
efforts to recover this wasted wealth
which in few years will undoubtedly
make itself known in a very great
increase in the value of California's
mineral products.
Congressman EnglebrIght has called
the attention of the bureau of forestry
to the situation in regard to grazing
stock IN the Tahoe forest reserve,
growing out of tho fact that small
part of the tract is in Neyadaa. He
holds that 1t is unjust to California
stockowners who pay for grazing on
the reserve and whose stock is taxed
] by the state, to have stock from
! Nevada driven over the line to pastur-
Y age in California, which can not tax
such property as it Is owned In New
ada, while California owners are de-
pTived of pasturage in their own
late. He suggests, therefore, that
d Efferent reserves be confined within
tlse borders of single states.
Congressman McKinlay will deliver
thl ee lectures in Illinois in February,
one at Springfield on Oriental trade;
one at Evanston ON the japanese
question in California;; and In
Chicsgo be will speak to the Credit
Mems Association on the Panama
canal and the Oriental question. His
aim is to make tho people this side OF
the Eockies acquainted with the
conditions which confront the Pacific
coast ny reason of its connection with
the Orient and the pressure Of
Oriental immigration.
The, river and harbor bill authorizes
surveys of practically all the rocks in
San Francisco that are menace to
navigation with view to their re-
moval. This is what the chamber OF
commerce of San francisco has for
years desired.
