work on the 31st ult. There are said to be 12,000
men there.

It would seem that troubles are not at an end in
Baltimore. The mob made a hostile demonstration
upon the guard of the 12th and 13th Regiments
(from what State not reported), while protecting the
baggage, which had been thrown off the track by
the rioters. Cheers were given for Jeff. Davis, and
three shots were fired at the troops.
From St. Louis it is stated that the Unionists in
Missouri are determined to crush out Secession by
force, and that General Harney has been removed
from the command of that department, and General
Lyon appointed in his place.

The Baltimore American of May 31 says :
" There are said to be about 700 Marylanders at Harper's
Ferry and vicinity under arms, formed into a regiment and
temporarily organised with Colonel George H. Stewart,
jun., as commander. General Lee was expected to visit
Harper's Ferry yesterday, to examine the defences."

All the speeches made at the recent sitting of the
Massachusetts Peace Society were of such a belli-
gerent tone that it had been suggested that the
members should enlist for the war.

A despatch from Chambersburgh states that the
rebel troops which had been stationed on the Poto-
mac opposite Williamsport, had fallen back in the
direction of Martinsburgh. They numbered about
500, and had two small swivel guns. While sta-
tioned, opposite Williamsport their numbers had
been reduced by desertions to the number of 100,
and the smallpox had also made some ravages
among them. Their object in making a retrograde
movement was not known, but they probably con-
sidered their proximity to the Pennsylvania forces
disagreeab 'e.

The new Military Department of Kentucky to the
command of which Colonel Anderson has been ap-
pointed, embraces all the State of Kentucky, which

lies within 100 miles of the Ohio River. His head-
quarters for the present will be at Louisville.
The New York herald of the Ist inst. thus an-
nounces the suspension of the postal service in the
seceded States:—
" Let all our readers remember that from and after this
day the United States' mail service is suspen led in all the
Confederate revolted States, excepting those portions of
Eastern Virginia occupied by United States' troops, and the
loyal Western section of Virginia, the good people of which
have refused to pass into the service of Moloch, and are as
steadfast to the Union as the people of New York. The
Confederate States have adopted an independent mail sys-
tun-5 and 10 cent postagca on letters; but, as we under-
stand it, no letter to a party in a Confederate State, intended
to be transferred from the United States to the Confederate
mails at the boundary line, will be transmitted through the
United States' mails. Mail matter for these States, of every
description, will from to-day be sent to the dead-letter
office."
The Herald of the 31st ult. says

" From a careful calculation, wo are satisfied that the
force of Federal troops now in service at the diffeetnt points,
which may be considered seats of war, amount to fully
95,000, and this does not include the men in the various
camps whose location is not yet decided upon. Tbis force
is stationed and commanded as follows : No.

entire Cabinet tcok formal leave of Montgomery on Sunday
last, and proceeded to Richmond, where they are no doubt

son, and ex-Senator Wigfall, of Texas, has been appointed
his chief aide-de-camp. Gen. Beauregard is in command
at Norfolk.
