Application having been made to the Government by R. B. Forbes, to have “letters of marque” issued to the propeller Pembroke, about to sail for China, Secretary Welles, in a letter of this date, writes that Congress has not authorized the issue of such papers against the Confederate States, and that if it had done so it would have been an admission of what the Confederates assume — namely, that they are an independent nationality. But the Secretary also thinks that, under the second clause of the Act of August 5, 1861, “letters permissive, under proper restrictions and guards against abuse, might be granted.” --(Doc. 63.)

The Council approved of the recommendation, and appointed Commissioners to make a treaty of alliance with the Southern Government.
