NEW GOLD•CRUSNING MACHINE.

An invention of extraordinary importance to
Australia, and to all gold-producing countries, has, we are
informed, just been imported from New York. This
machine promises not merely to supersede all other crush-
ing machines, but actually to nearly treble the value of the
immense auriferous fields which have already yielded so
ri h a harvest. It is the invention of Mr. Borden, who, in
consequence of the unsatisfactory results produced by other
machinery, sent two 011110110,111 to study the subject in Cali-
fornia. It performs the various operanone of washing, pul-
verising, and amalgamating ; and it comes to Englandwith
a well-certified character that promises to earn for it the at-
tention at once of the scientific and of the mining world. It
includes points of groat novelty, both mechanical and'
chemical. In the fiat place, the pulverising mill is
both novel and curious is its arrangement. It consists of
• large iron basin revolving on an inclined axis, with an
enormous ball of iron lying in its lower part, and having a
curious spiral action given to it by simple and ingenious
means. The chemical portion of the invention consists in
' the important discovery that amalgamation proceeds with
greatly increased activity whoa boat la applied to the mix-
ture. The third peculiarity alms Erik* is that the amal-
gamation of the metals is effected at the moment of player'
nth's, and beneath the surface out of the reach of oxida-
tion. The ore, after being roughly broken up. is placed in
the basin with the quicksilver—fire is applied beneath and
water above the mixture, the mill reduces the (toads or''
sand to as impalpable powder—the quicksilver instantly
catches up the disengaged gold—the water carries =ll
the earthy particles, together with any impurities from
the upper surface of the mercury—and finally the amal-
gam is left pure and complete at the bottom of the basin.
It is proved on good authority that the ordinary gold.digger
doge not secure more—frequently less—than one quarter
of the precious metal contained in the ore on which he
works. His gets only the disengaged gold—and loses all
that is more ultimately blended with the matrix. It is
also clearly proved that other machines now in use secure
about only one-third of the gold. bit. Berdan'e pulverizer
and amalgamator so completely exhausts the ore, that
eminent chemists have been in several instances unable to
detect the existence of gold in the residuum left by the new
machine. Another and most decisive proof of the excel-
lent working of this new machine is, that it has produced
nearly twice as much gold from the " tailings," • rubbish
left by other machines, as they had succeeded in extracting
from the original ore. The facts are attested by the met
respectable scientific and other journals of the United
States.—Atheneum.
