PLANTING AND CULTIVATION OF THE SEA

ANS, March Z0.-"hat the French call ''the
planting and cultivation of the sea-" and the Eng
lisn, less ambitious in speech would be content 10
call "the artificial raising of fish, is carried on in
france with a perseverance and success which
promise TO yie!d very valuable results, and at no
Instant GATE. The various operations of modern
piscicuture, due to the inventive genius of the
humble fisherman Remy, and zealously promoted
| by the labors of the interchangeable ii. Jacoues
Coste, under the joint auspices of the Imperial
government and of the Society Of Acclimation arc
r&Pialy REDUCED to system at once easE a If ANIL
apparently, to render the raising of fish as common
as that OF kline, sheep, wheat and potatoes,
rivers, lakes and ponds exhausted by the i'm
provident greed of fishermen and the destruction
OF the young Try, are stocked from the great rails
ing establishments founded in various departments
and the coast of the Channel, the Atlantic and the
Medlterranean are converted into oyster grounds
which threaten if their tenants continue to mnIti
ply as rapidly they are now doing, to ensure
Surelt OF that dainty for the entire population of
France.
THE FIRST ARTIFICIAL oYsTER-BED
The first OF the great artificial oyster-beds was
undertaken by NJ. Coste in 1857 in the hav of 81
Brlenne, on the northern coast of Britanny The
water Is there exceedingly deep, and the violence
OF winds and weather added greatly to the difficult
ties OF this novel attempt. But all these obstacles
were successfully overcome The entire surface of
the bottom of the bay forming the piscicultura
farm is covered with ascines, composed of branches
OF trees strongly lashed together and held down by
heavy stones. Between these fascines the he'd of
the sea is paved with oysters aud muscle shells
pieces of rock, tiles, fragments of pottery destined
to attract the spawn and afford to the Youngest
oysters a surface suitable to their DEVELOPMENT
FIsH-FARMs.
The success of the experiment at ST. Brienne has
led to the formation of similar s'fish-farms' at
Arcachon, the lie de Re, and in the roadstead of
Iouon, all OF which are now cultivated with unre.
hitting care. and promise, according to the reports
OF the periodic inspections to which they are sub
Jected by the agents of the government and by
those OF the Society of Accimation, to inaugurate
new era in the annals of ish-markets and to Gre
ate new and inexhaustibe source of national
wealth.
The last Investigations into the state of the oys
ter-beds of st. Brienne, carried on by members of
the Council General of the department of the Cotes
du Nord, under the direction of the captains of the
Chamois, Pluvier and Eveil of the French navy.
placed by the government at the disposition of the
commissioners charged to carry on the work of in
spection, have given results that have far surpassed
the most sanguine expectations of the advocates of
the new system. Every time the drag was applied
1t brought up over two thousand OYSTERS and each
of three fascines of row No. 10, sunk in 1852 and
just brought up for examination, was found to con-
tain twenty thousand young oysters from three to
live centimetres in diameter. These fascnes ex-
hibited in various towns of Brittany, created uni
versal amaZement, and will probably lead to the
establishment OF many new beds. They were SUBJ

New York, April 15 1861. I
To the People Of the City Of Net0 York:
As chief magistrate, representing the whole peo-
Pile, feel compelled at this crisis to call upon them
to avoid excitement and turbulence. Whatever
may be or may have been individual positions or
opinions questions of public polity let us remem-
Der that our country now trembles upon the brink
OF precpce, and that it requires patriotic and
honest effort to prevent its final destruction Let
us Ignore the past, rising superior to partisan
siderations and rally to the restoration of the Con-
sttution and the Union as they existed in the days
and in the spirit of our fathers. Whether this is to
be accomplished by fratricida warfare or by con-
cession, Cancellation and sacrifice, men may differ,
but all will admit that here at least harmony and
peace should prevail. Thus may we, under the
guidance OF Divine Providence, set an example of
peace and good will throughout our extended coun-
try In this spirit and with this view, call upon
the people of New York, irrespective of all other
considerations or preudices, to unite in obedience
to the laws in support of the public peace, in the
preservation of order and in the protection prop
erty. FERNANDO WooD, Mayor.
