Hudson River potentate is looked forward to with great interest.

"CENTRAL" REPORTS.

VANDERBILT received the Declaration of War with seeming calm. On the
departure of the Erie Emissary, however, his fortitude forsook him; he
threw himself on the neck of a baggage porter and wept aloud. At a late
hour this evening a trusted agent left here for the _Tribune_ office. He
is said to have held a long conference with Mr. GREELEY, the particulars
of which have not transpired. It is supposed by many to portend an
alliance, offensive and defensive, between the King of Central and the
Philosopher of Printing-House Square.

FROM ERIE.

Activity is the order of the day here. Col. FISK'S $20,000 team went to
the front this morning. They are to be broken into the turmoil of war by
being led gently to and fro, before a Supreme Court injunction. A
Central spy, who was captured during the day, was immediately tried by
court-martial, and sentenced to be suspended from the flag-staff on top
of the building. He was executed at noon, a copy of the _Tribune_ being
tied to his feet, to add force to his fall and curtail his sufferings.
From legal documents found in his possession, the wretched being is
supposed to have been a minion of the law. The Narragansett and Long
Branch boats are being rapidly got ready for active service. Their
armament will consist of Parrott guns of large calibre. FISK says that
VANDERBILT will hear those Parrotts talk.
