may throw some light on this interesting subject.

The principal value of gold is as a medium of exchange, and its high
appreciation is due, first, to the fact that it is in almost universal
request; and, secondly, to its comparative scarcity; yet, oddly enough,
with the exception of that humble but serviceable metal iron, gold is
the most widely distributed metal known. Few, if any, countries do not
possess it, and in most parts of the world, civilised and uncivilised,
it is mined for and brought to market. The torrid, temperate, and frigid
zones are almost equally auriferous. Siberia, mid-Asia, most parts of
Europe, down to equatorial and southern Africa in the Old World, and
north, central, and southern America, with Australasia, in what may be
termed the New World, are all producers of gold in payable quantities.

In the earlier ages, the principal source of the precious metal was
probably Africa, which has always been prolific in gold. To this day
there are to be seen in the southern provinces of Egypt excavations and
the remains of old mine buildings and appliances left by the ancient
gold-miners, who were mostly State prisoners. Some of these mines were
worked by the Pharaohs of, and before, the time of Moses; and in these
dreadful places thousands of Israelites were driven to death by the
taskmaster's whip. Amongst the old appliances is one which approximated
very closely to the amalgamating, or blanket table, of a modern quartz
mill.

The grinding was done between two stones, and possibly by means of such
primitive mechanism as is used to-day by the natives of Korea.

The Korean Mill is simply a large hard stone to which a rocking motion
is given by manual power by means of the bamboo handles while the ore is
