Department their resignations, 'which were refused. Their
names will, probably, be struck from the list as dismissed)
as in the recent cases of several officers of the army -under
similar circumstances.

The National Volunteers last night passed a resolution
severely denouncing the military operations of the Govern-
ment, and expressing sympathy with the Secessionists. It
is said these volunteers are several hundred strong.

Another despatch from the Federal capital, of the
same date, says ;
Information continues to be received from private sources
of secret plots in various localities in Maryland and ir-
ginia, having in view the seizure of the public property and
even persons, the highest officers of the Government.
Though these accounts are not generally credited, they are
believed in official quarters, and hence the precautionary
movements. At all events they are considered necessary, no
one knowing what turn events may take during the preva-
lent excitement.

Information from what 'are deemed reliable sources was
received last night to the effect that the Secessionists of
Delaware, whose head-quarters are reported to be in Vir-
ginia, were about to make a sudden attack upon Fort Dela-
ware, opposite Delaware city, for which they were prepar-
ing last month. Immediate steps were taken by the
Secretary of War to prevent the consummation of the plot.
The Virginia Commissioners returned to Richmond to-
day. They were cautious in expressing their opinions
relative to the President's reply,
Senator Douglas called on the President to-night. He
had an interesting conversation on the present condition of
the country. The substance of it was, on the part of Mr.
Douglas, that while he was unalterably opposed to the Ad-
ministration on all its political issues, he was prepared to
sustain the President in the exercise of all his constitutional
functions to preset ye the Union, maintain the Government,
and defend the Federal capital. A firm policy and prompt
action were necessary. The capital of our country was in
danger, and must be protected at all hazards, at any ex-
pense of men and money. He spoke of the present and the
future, without reference to the past.
The interview of Judge Douglas with the President was
not only exceedingly gratifying to both, but is the subject
of much rejoicing by the friends of Mr. Douglas here.
Colonel Ellswoith intends to raise a regiment of picked
men in Illinois, who will be armed with an improved rifle
and sabre, and uniformed and equipped for the Zouave
drill. Every company will have one or more commissioned
and non-commissioned officers, thoroughly competent to
teach the Zouave drill, and the regiment will be hurried
through with all possible despatch. Colonel Ellsworth has
special instructions from the Government with regard to
the matter.

The news from all parts of the States gives evi-
dence of the greatest excitement everywhere, and
arming, recruiting, and other warlike preparations
were going on.
