The blockade.
--Our correspondence from the seaboard represents that Lincoln's blockade of our ports is in full operation. The following is Commander Pendergrast's notice to captains of steamers:
U. S. Flagship Cumberland
I hereby call attention to the Proclamation of his Excellency Abraham Lincoln, President of the United States, under date of 27th, 1861, for an efficient blockade of the ports of "Virginia" and "North Carolina," and warn all persons interested that I have a sufficient naval force here for the purpose of carrying out that proclamation.All vessels passing the Capes of Virginia coming from a distance, and ignorant of the proclamation, will be warned off, and those passing Fortress Monroe will be requested to anchor under the guns of the fort, and subject themselves to an examination.
