Architect and Inventor, has shown us a gold
saving machine of his invention, for which
he will apply for a patent at Washington.
The principle on which it works may be arrived at from the following rather brief description:
It is simply a large bowl of cast iron, in
the form of those used by miners, when working
by hand, and so arranged in connection
with machinery that it assumes the same vibrating,
or electric, motion that is produced
by hand in the well known process of pan-
ning out gold. By this method the coarser
particles rise to the surface, incline to
the edge of the bowl and fall out, while the
gold, mercury, and all heavy substances approach
to the center and there remain so long
as the motion is continued. The simplicity
of the apparatus is one of its best recommendations,
as it can be operated by one individual,
and is said to work dry earth or pulver-
ized rock with equal facility as if it were
done with water. The peculiar motion imparted
to this machine, so far as our knowledge
extends, is admitted by practical miners to be the most efficient method for extracting
and collecting gold, heretofore known.

Vincent Brown, Esq., Architect and Inventor, has invented a gold saving machine consisting of a large cast iron bowl that vibrates like hand panning to separate gold and heavy substances from coarser particles, operable by one person on dry earth or pulverized rock, and plans to patent it at Washington; practical miners admit its efficiency.
