in the Persian Gulf, and the islands in
the vicinity of Panama
THE best pearls are obtained in the.
Persian Gulf. They excel in color,
size, purity and that translucency
which gives this gem its greatest value.
The pearl fisheries in the Persian Gulf
are said to yield upward of 81, 500, 600
annually. Those of Panama reach
about the same figure. Pearls have,
also been found in the waters of the.
United States, and in 1858 considerable.
excitement was occasioned by the dis
covery of large pearls near Salem, in
New Jersey. A New Jersey pearl,
over an inch in diameter, found near.
Paterson, was sent to Paris, where it,
was purchased by the Empress Eu-
genie for 81, 800, and when the crown
jewels were sold last year by order of
the Ferry Government it was resold

"Can pearls be produced at the will
of man, or can they be multiplied
by manipulation? 1t is asserted by
oyster fishermen, and can be accepted
as true, that the pearl oyster has the
power of covering with additional
layers such portions Gifts shell as need
strengthening, as we'll as objects intro
duced by accident or design. The Chi
nese and Japanese, taking advantage
of this, have long practiced the art,
of stimulating the secretion by intro
ducing beads made of spar or powdered
glass and varnish, or sometimes turned
from mother-of-pearl, and thus do they
actually succeed in forcing the animal
to produce pearls at their will, though
of an inferior quality.
Gone of the curious circumstances
connected with the New Jersey pearl
fever of 1858 was the discovery of a.
few shells showing that many years
before some one had experimental upon
the pearl-bearing oyster by dropping
small mother-of-pearl buttons inside
the shell, hoping that the animal
would, in course of time, cover them
with its secretion. The experiments
proved a failure however, the result
being that the buttons became fastened
to the shells by the action of the secre-
ton, but did not develop into pearls"
Some time ago number of small
pearls of the kind known in commerce
as 'seed pearls" were sent from Bor-
neo, under the name of breeding
pearls" These pearls are enclosed in
a glass tube along with some grains of
rice "to feed upon" The sender gravely
asserted that it had long been known
in Borneo that pearls when put up for
some time in box along with rice
would reproduce their kind. Three or
four months afterward the grains of
rice enclosed with the pearls had the
appearance of being partially eaten.
1t is now several years since this ship
ment of pearls and their food was re-
ceived, but the rice does not seem to
have diminished to any greater extent
than when they arrived, and the pearls
themselves are no greater in circum-
ference than when first seen.-N. Y.
