secret, but he does not hesitate to say
that sodium in some form is the bases.
Perhaps common salt. No doubt,
electricity also plays an important part
in the operation. The practical work
ings of the apparatus seems to be OK
tremely simple. In order to test its
efficacy, gentlemen who were present
washed number of pans of the gravel
taken directly from the river bar, each
of which showed gold in more or less
quantity, but after repeated washing
of the sand which had passed through
the amalgamatOr, no trace of gold was
found, except in one instance where a
single color was seen. but as the same
pan had just been used for washing
bar gravel, it is supposable that par.
ticle of gold had adhered to the pan.
We took occasion to calculate the
amount of gravel that could be handled
and by actual timing it was Shown that
about 200 pounds per minute was a
conservative estimate. This would
amount to six tons per hour, or 60 tons
per- day of ten hours. Under favorable
conditions, four men could easily
operate the machine and other expenses,
including royalty should not exceed
So per day, making a total running ex-
pense of $l7 per day. The plant will
probably cost, put in operation, about
$1,000, where each machine is operated
independently. But this cost eau be
greatly reduced where electricity can be
furnished from central station. 1t
is estimated that the gravel will pay
about 81 to the ton, but it would seem
that at IS cents, or even 30 cents, it
could be worked profitably. However,
the main questions for consideration
at present are, first, is the gold in the
sand; second, will the apparatus save it
an third, is it practicable To the first,
there is but one answer: The gold is
unquestionably there; to the second,
there is gold in the sand before 1t en-
ters the machine, but there is none in it
when it comes out-the gold must be
saved; to the third, every appearance is
favorable. MIR. Raber, the inventor,
Informed us that the cost of the chem
icals would not exceed t EN- cents per
day. Now with respect to terms of
machines: AS we understand
it, no machines will be sold outright,
but the first cost for putting up will be
between four and FIVE hundred dollars,
and thereafter one dollar per day roy
atty must be paid. These figures do
not include cost of power and dynamo.
At present the company have no ma
chimes, amolgamators rather, to dispose
of. as those on hand have already been
taken. Ten of them will he placed be-
