_Resolved_, That in view of this threatening evil, it is, in the opinion of this Chamber, the duty of our Government to issue at once a proclamation, warning all persons, that privateering under the commissions proposed will be dealt with as simple piracy. It owes this duty not merely to itself, but to other maritime nations, who have a right to demand that the United States Government shall promptly discountenance every attempt within its borders to legalize piracy. It should, also, at the earliest moment, blockade every Southern port, so as to prevent the egress and ingress of such vessels. (Immense applause.) _Resolved_, That the Secretary be directed to send copies of these resolutions to the Chambers of Commerce of other cities, inviting their co-operation in such measures as may be deemed effective in strengthening the hands of Government in this emergency. _Resolved_, That a copy of these resolutions, duly attested by the officers of the Chamber, be forwarded to the President of the United States. BLOCKADE RESOLUTIONS. _Whereas_, War against the Constitution and Government of these United States has been commenced, and is carried on by certain combinations of individuals, assuming to act for States at the South claiming to have seceded from the United States; and _Whereas_, Such combinations have officially promulgated an invitation for the enrollment of vessels, to act under their authorization, and as so-called "privateers," against the flag and commerce of the United States; therefore, _Resolved_, by the Chamber of Commerce of the State of New York, That the United States Government be recommended and urged to blockade the ports of such States, or any other State that shall join them, and that this measure is demanded for defence in war, as also for protection to the commerce of the United States against these so-called "privateers" invited to enrol under the authority of such States. _Resolved_, That the Chamber of Commerce of the State of New York pledges its hearty and cordial support to such measures as the Government of the United States may, in its wisdom, inaugurate and carry through in the blockade of such ports. A PROCLAMATION, BY THE PRESIDENT OF THE UNITED STATES OF AMERICA, BLOCKADING THE SOUTHERN PORTS. _Whereas_ an insurrection against the Government of the United States has broken out in the States of South Carolina, Georgia, Alabama, Florida, Mississippi, Louisiana, and Texas, and the laws of the United States for the collection of the revenue can not be efficiently executed therein conformably to that provision of the Constitution which requires duties to be uniform throughout the United States:
