THE NEW FIELD TELEGRAPH.

THE NEW FIELD TELEGRAPH.
Yesterday, Telegraph Engineer Rogers, of New
York, put in operation on the other side of the
river his newly invented telegraphic cordage or
insulated line, for field operations, and it proved
eminently successful, giving entire satisfaction in
the manner in which it operated It's run off reels
upon the ground with great rapdity, (as required
for instant use across streams, through woods or
over any localities. 1t is worthy of note that the
heaviest artillery may run over this Rogers cord
age without damaging its effectiveness in the least.
1t differs in many respects from the field telegraph
used by Louis Napoleon in the Italian war, and
embraces many advantages OF convenient and GER
tain operation under any possible circumstances
that (Louis Napoleon's) which contributed SO
signally to the success of the French arms.
ALEXANDRIA, June 2l.-lt is very apparent to those
who acquainted with the Potomac, Rappahan-
mock and York rivers. and other points heChesa
peake that the Southern forces led by experienced
resigned engineers and naval officers preparing
batteries at various places on those rivers, which,
before aware, will totally close their navi-
gation-that of the Potomac in particular. Thus
far they have had all the opportunities they could
desire for the purpose, and are availing themselves
of them, no doubt, most effectively. The United
States, meanwhile, doing-what? Sending a
little cockboat, a miserable she'll of river
steamboat, to pop a few guns at them-getting the
boats well peppered, and the men killed.
THE FUTURE OF CorroN.-If the American war,
and blockade, and bankruptcy, and loss of slave
labor should raise the price of cotton wool much
as is feared, and if this staple is made to pay the
cost of the on both sides by an immense export
duty, we shall then see the pressure which is to
make India do its part in the family of nations
Dearth is the great stimulus of industry, whether
in corn, wine cotton. Dearth will soon test the
value of any calculation to the frendliness of
climates and the capacity of soils. Lord Broug ham
tells US that the British West Indies will grow any
quantity of cotton. We shall see whether it be so
v hen the American blockade has doubled the price
and left US uncertain whether to keep the mills
open. Unless the Omitted States" settle their diff
ferences, or agree to disagree and divide the land
between them, they will see the great Indian Pen
insula fretted with railways and canals, and dis
charging at every outlet piles of ootton worthy of
Charleston or New Orleans. AS to the West In
dies, the producing power of Jamaica must depend
on the population, and the iEducement it NAV
have to do regular work. 1t is not generally be-
lieved to be formidable rival to the SotheIn
States But who shall say what changes will not
take place in the course of the next few years.
Here we have India reconquered, the Chinese Em-
pire in the process of dissolution, the Old World
sick at heart, and now the United States at the
end of their brief history. ALI the countries of the
world are newly opened, and all the currents of
population set flowing here and there, where a
vacuum is to be filled, an accumulation discharged
or a channel to be found. Under these circum-
will be tied to one spot. 1t will follow labor, cap
ital and enterprise. After what we have seen of
is growth in the States, in Egypt, and even in In
dia will not venture to say where next it will
establish itself.-London Times.
