Diamond mines and mining -- South Africa; South Africa -- Description and travel
Before passing on to the Dry Diggings and the systems that there
prevailed, it may be as well to briefly describe the “sorting table.”
The top of a packing-case balanced on a heap of gravel often had to
serve this purpose in the early days of the river diggings, and beside
it the digger knelt, crouched or sat, changing his position when it
became too wearisome. The more affluent had a sorting table supported by
legs, and covered with a sheet of iron, being slightly inclined from the
digger, so that the water might not flow into his lap when the gravel
was poured out in front of him. Those of my readers who visited the Cape
court in the “Colinderies” have seen a sorting table almost if not quite
identical with the best constructed of the early days. The “scraper,”
too, which, though small in size and inexpensive in material, is yet an
important instrument in diamond winning, has but little altered. This
little wonder is not much to look at, being simply a piece of tin or
iron about six to nine inches in width and three to four inches in
height, with a straight edge and pointed ends. With this the sorter
scrapes—scrapes—scrapes, pushing over the edge of his sorting table,
garnets, jaspers, carbons, agates, pyrites, crystals and pebbles, which,
however interesting to the scientist, are commercially valueless, until
at last a diamond is found, and then the precious stone, large or small,
is dropped into an unpretentious tin or perhaps a broken bottle, and the
process goes on as before.
At the dry diggings sieving and hand-sorting were at first the usual
methods employed, and it was long before even so much ingenuity as was
required to construct an improved or altered cradle was brought into
play. The processes named, however, being so wearisome and exhausting,
they were at last abandoned; and among other labor-saving appliances
one, for which much _kudos_ was gained by the inventor or adapter—a Mr.
Van Doussa—was largely used, but does not need detailed description, as
it was simply a combination of the Long Tom and the cradle.
