The daily exchange. [volume] (Baltimore, Md.) 1858-1861, 1861-03-21

From KEY WEsr.-Key West, March l2-No
synopsis of President Lincoln's message has vet
come to hand. The utmost anxiety exists here to
learn the position of the President and his future
policy as regards the Florida forts.
The garrison at Fort Taylor remain, as last re-
ported in good health and spirits. They are look
ing for reinforcements by the Daniel w ebster from
Texas. The steamer from New York and Fortress
Monroe, with the ornaments of Forts TAYLOR and
jefferson, is now over due.
There are no vesses-of-war at the present mo-
ment stationed at Key West. The city is perfectly
quiet, and the people seem Opposed to calmly await
the denouement of events. The federal authorities
holding the Notifications will have undisputed
sway.
The U. S. mail steamer Magnolia, Crowell, ar
rived from New Orleans the 9th and returns to-.
day. 1t is reported that this is the last trip to be
made by this line. Such, trust, is not the case
Should they be withdrawn mail facilities are
gone, and the only dependence will be the uncer-
tain of transient vessels and the Havana fishing
smacks.
The coast survey schooners, Agassiz and Bailey
have arrived at Fort Jefferson. They are to leave
soon for the North. Major Towers, of the United
States engineers, and Lieut.. Gilman, of Fort Pick
ems fame, arrived from Havana on the 9TH inst and
left in the transport schooner Tortug3s for Fort
Jefferson on the 9th. Lieut. Gilman is en- route
for Fort Pickens, Pensacola.
The U. 5. revenue cutter Appleton, Lieutenant
Randolph, sailed for Havana on the 4th, with Capt
W. F. Smith, U. S. Top. Engrs., as passenger.
THE "BLAcK PRINcE,' the new English iron-cased
screw frigate-the companion, as it may be term
ed, of the Warrior-was successfully launched on
the 9th, from the building-yard at Govan, south
bank of the Clyde. The spectators were very nu-
merous, and great excitement prevailed. The
graceful and easy movement of the vessel down
the ways into the water was the theme of general
remark. There was no lurch or unsteadiness in
her whole progress into the river. Several of the
checking chains and cables were never put to the
strain, and the noble-.ooking vessel was rounded
and brought to right position in the river, with
out jerk or accident of any kind. The Black Prince
has the following general dimensions: Length
extreme about 420 feet; length between perpendic-
ulars, $50 feet; breadth extreme, So feet; depth
from spar deck, Az feet; and builders measure
ment, GLIB tons. She has been constructed to
carry 40 guns, 81 of which to be placed on the
lower and on the upper deck. 1t is supposed
that the vessel will be mounted with 6S-pounder
longrange guns, but it is probable that ultimately
Armstrong l00-pounders or rifed guns will be in
troduced About 2l3 feet of each side of the ves-
sci is rendered invulnerabe by shot or SHE'LL by ar
NOR plates of wrought iron, from Is to 16 feet long,
to broad, and ~ inches thick, each averaging
upwards of tons. Their edges are planed, and
they are fitted together with tenon and groove
Joints. The moulded depth of the vessel is Al feet
The plates cover p feet in depth of the top
Sides 16 of which will be exposed above the water
line the armor thus descending about feet below
the surface of the water. The figure head, which
represents Edward the Black Prince in complete
suit of armor of the period, has been carved from
a built block of wood, l6 feet in length.
A CALCULATION ABOUT THE CoTToN CRoP.-The
following calculation of the probable yield of the
cotton crop for the next ten years, is given by the
Mobile Advertiser, for the purpose of showing the
sautary effect of the proposed export duty at
is not an exravagant estimate that the cotton crop
of the eight States, during the next ten years, will
increase forty per cent. But when to this is added
the consideration that, in the event OF the Border
States standing aoof from the South, an increased
emigration hither of the citizens of those States
with their families of slaves, is sure to take place,
we may safely disregard the four and "a half per
cent of the crop which is produced in those States
ana base our calculations upon the former entire
crop OF the United States. On that basis, the er-
pecfdton OF future crops in the Confederate States
is as follows:

The Advertiser estimates that in the year 1874
the sum of ST. l6l, 597 would have to be prov;ded
for, while the duty would yield So 9I 400 or nearly
three times the necessary amount

The Alexandria Gazette say; Many of the stories
set afoat recently about emigration from Virginia
to certain other States, said to be all CANNON.
The probability is that the emigration will be to
Virginia. Our State is the best, greatest, safest
land on the continent of America.
