Amusing inquiries concerning the
production of pearls frequently come
to the bureau in connection With It's
oyster development. The belief that
aluable pearls are frequently found
Dotted as it is erroneous. The pearl
oyster is developed entirely by salt
water and cannot be eaten. The
formation of the shell of an ordinary
oyster gives no ~Dlance 70 pedfly

The effort of the Government to
increase the Nations fish supply in
cludes many other activities. No
result accomplished for years has been
more pleasing to it than the final
success in establishing the Chinook
salmon of the Pacific coast in the wa
ters of the East. For nearly forty
years this effort has been in progress
and only during the last year has
there been any indication OF success.

There ever has been a period in
which the demand for fish has aver
aged 50 great in proportion to the
population as now. This is partly due
to immigration and the influence Of
North Europe who have settled in
the Middle West. The observance of
Lent. as regards eating fish. is be-
coming each year more universal.

during this period than at other times
because there are larger quantities
and more varieties on sale in the
market.
This increase in the demand is be-
ing more than met by the increase
in production Of most kinds of fish.
While the supply of one or two va
%rieties is decreasing, the increase Of
other species more than equalize this
loss. A makerel investigation carried
on during the past year at the pc
cial request of the Board of Trade
and Master Mariners Association of
Gloucester, Mass, occupied a period of
six months. 1t resulted in much val

habits of this fish, their movements,

An interesting experiment in fish

coast. Over 1000 cod fish were
caught at various times during a
period covering four Years. They
were released, after being tagged with
q little numbered copper disc about
three-fourths Of an inch in length and
A small hole was punched in one end
and a thin, copper wire passed
through for attaching the tag to the
fish. The average weight Of the tag
was about equal to a silver dime. Most
of them were placed in the upper
part of the tail where the rays were
thickest and the tag less likely to be
torn out. The weight, length and
sex Of each fish was recorded with
Its unbe before it was released.
