I'm France and other countries oyS-
ter cultivation has been carried on for
long time, and, in fact, there is reason
to believe that in the days of the
Caesars attention was given 10 this
matter. The French government in
1851 made experiments in spat culture
by strewing shells on the bottom
"Oyster culture by this method is

''The term fry, as used by me, means
free swimming embryo. The existence
of the embryo is divided up into three
stages. First, there is the egg. which
when fertilized passes through its
early stage from three to ten hours.
and then becomes fry. The next stage
is when the fry settles and fastens it,
self TO some object, makes its home
for life, and then it becomes spat. The
fry swims until it finally meets some
object to which it can attach itself.
Once fixed, its wandering existence
is at an end
you see these Shells" said the SCI
enlist, taking up a number of small
oyster shells. These l took from
buoy poles at Cohasset. There you see
these little specks," he continued,
pointing out tiny little dots on the
shells-so small as hardly to be visible
They are little oysters, or spats. L

croscope."
One of the shells was adjusted under
the glass and the specks at once APP
peared to the eye as mollusks of quite
respectable size.
You could range 500 OF the eggs or
fry in the space of an inch," said the
scientist. The oyster lives "a hours
as a free swimming embryo. Then it
begins to form its valves. and, if it has
not attached itself, sinks to the bot
tom and perishes there" >

when left to natures processes, very
larger" asked the reporter.
THE losses prior to fixation are very
great. By enroomusly increasing the
cultch or spatting surface, however,
we can reduce the loss to the mini
mum. Prof. Moebius made a calcula-
ton as to the oysters of Europe, that
only one egg out of ], 400, 900 ever comes
to maturity. As the American oyster
is fully four times as prolific, the losses.
under natural conditions, are rela-
lively much greater. The oyster has
a great many enemies, such as the
drills and star fishes. Then they are
often so crowded that thousands are
killed"
HAS observation shown that there
is need of recourse to artificial cul-
ture to keep up the supply?"
"The results of last years investiga-
tions by the Fish Hawk showed that.
We found that nearly all the oysters
were understood. The beds were by
no means exhausted, but they were
so closely fished that they were not
given time to recuperate. We exam
med oysters at over 90 different points
in the Chesapeake"
The next time you eat an oyster
stew, think of the amount OF scientific
work which is required to keep our
