the black sand subject Is really one Of very
great interest and Is going 10 aid very much good

The Iu',r oceans article describes the ex-
rcr'uonts on the separation of the black sand
into H. constituent parts. gold. chronite,
,]onl7itc, zlrcon, etc, Moreover, one of the
urinnipal constituents of the black sand is
magucfite. the magnetic oxide of iron. and
-Dr p,y. after demonstrating that many or
the sands tested contained as high AS e00
rounds OF iron to the ton, erected a ten ton
s,rtr,r furnace. and in one short hour. nv
.Ilipc lime and broken coal 10 tho iron
which had been separated from the black
,auIs. smelted the iron into high grade
steel.
The immense importance. of the steel in
d,stry on the Pacific Coast is discussed. the

-Dr Day and the work of his associates
have demonstrated beyond question" Among
these results are the follow ing;

the company's superintendent in which
Mr.. Batchelder asserts that as a result OF
certain tests made at the request of prof
Richards il was found that the Lovett mag

machine. This machine Is said TO be con- |

owned by the Black Sand and Gold Recovery
Company was tested. In another part of
his letter Mr.. Batchelder says that one OF
the strong features Of the Lovstt machine
Is its ability to handle the material wet. Thus
f. ia not necessary TO dry the sand. (which
must be done Ia the case of every other separa-
tor. This IL absolutely false. for there are
other wet separators.
This example shows very clearly the
