AUSTRIA AND PRUSSIA.

FRANKFORT, April 23.—After the ratification of
the treaty between Austria and Prussia, the Ger-
manic Diet will receive a communication on the
subject of the war, and will proceed to consider it
at the second sitting after the Easter holidays.
The Constitutionnel has the following on the
treaty of alliance of Austria and Prussia :
The treaty of alliance between the Courts of Berlin and
Vienna is a fact on which there at present remains no
doubt, and although this document has not yet been pub-
lished, public opinion, which takes a lively interest in it,
has penetrated the signification of it. In Germany, all
persons agree in saying that the treaty establishes
between Austria and Prussia an offensive and de-
fensive alliance, with respect to existing circum-
stances, and to the eventualities of the war which
is commencing. One of the difficulties which
might embarrass the action of Austria was the
fear of seeing some part of her territory menaced while
she was engaged on the Danube in a direct conflict
with Russia. It appears that the treaty of Berlin con-
tains on this subject a mutual guarantee, and that this
guarantee embraces such of the provinces of the two
States as are placed out of the pale of the confederation.
We are assured that the treaty of alliance contains also
clauses which fix the measure of the armed co-operation
Prussia is to afford to Austria in the case provided for.
Europe cannot do otherwise than rejoice at seeing these
two Governments in accord, to follow in the war, which
menaces their interests still more directly than those of
the other Powers, a line of policy in conformity with.
the interests of all. Now that the question of the
understanding between the German Powers is regulated,
we express wishes that that accord shall lead as soon as
possible, and in express terms, to a junction with the
alliance which France and England have just concluded.
It is in conducting hostilities with ensemble and with
energy that we may hope to lighten the burden and
abridge the duration of them.
A private letter from Vienna, in Spener's Jour-
nal, contains the following statistics of the troops
which Austria has under arms, in readiness to act
on the Servian and Wallachian frontiers

" At the beginning of Februaiy, the 9th corps d'armee,
under Lieutenant-General Count Schaffgotsch, part of
which garrisoned the capital, was pushed to the south
frontier of the Banat. These were followed ere long by
a second army corps, formed from the troops of the first
army, quartered in Bohemia, Moravia, and Austria
(Proper). Each of these corps formed a total of 25,000,
or 50,000 in all. At the beginning of March, the third
army, cantoned in Hungary and Transylvania, was
mobolised. It consists of the 10th and 11th army corps,
under command of the Archduke Charles Ferdinand
and Lieutenant-General Count Wengersky, in Hun-
gary, and of the 12th army corps in Transylvania, com-
manded by Prince Schwarzenberg. The amount of
these three corps may be taken at 80,000 mon, the half
of which, with 20,080 Grenz' troops, and 12,000
cavalry, are added to the south frontier army. So that
of the remainder of the Grenz battalions, dislocated
along the Croatian frontier upon the right flank of the
grand army, the total will amount to more than 160,000
combatants, ready to advance at a moment's notice.
But the preparations for Eastern eventualities do not
terminate here. Dalmatia, a point of great importance,
is occupied by 20,000 men. Provision has also been
made for an efficient reserve. This consists of half the
10th, 11th, and 12th army corps, about 40,000, and of
the 6th army corps quartered in the Venetian territory.
So that the south corps (Schaffgotsch's), including the
reserve, and the corps in Dalmatia under Lieutenant-
General Mamula, present an effective force of 260,000
men ready for action in the East, and this independent
of all other corps echeloned in divers parts of the
monarchy."
As the words " armies," and " army corps," em-
ployed in these details, may give rise to confusion,
it may not be irrelevant to observe that the Aus-
trian military establishment is divided into four
armies, subvided into thirteen army corps thus :-
ISIT ARMY— Ist army corps, head-quarters at Prague;
2d ditto, bead-quarters at Brunn ; 3d ditto, head-
quarters at Gratz ; 4th ditto, head-quarters at Vienna.

10th ditto, head-quarters in West Hungary ; 11th ditto,
