Mr. Harvey to Mr. Seward.
Sir: It will be seen by the enclosed copy (in translation) of a note from the Duke de Soulé, and the royal portario which accompanies it, that the hope and confidence which I ventured to express in my No. 250 as to the effect of a note addressed to him on the 14th instant, regarding the movement and designs of certain piratical cruisers, were not merely speculative. This government seems to have been awakened to a sense of its responsibility, and the consequences that might result from a neglect of plain and upright duty.
A great point will be gained if these hostile cruisers can be effectually shut out of the retreats which they seek at the mid-ocean islands, to recruit and equip for the destruction of our commerce, and I believe this last measure will be effective for that purpose. But if any other proceeding or precaution shall be suggested by experience as necessary, it will be my duty to urge it promptly and firmly.
The United States sloop-of-war St. Louis sailed yesterday (Sunday) morning, bearing the official despatches of this government on the subject to all the civil governors of the different islands.
I communicate, also, herewith, a copy of my reply to the Duke de Soulé.
I have the honor to be, sir, your obedient servant,
Hon. William H. Seward, Secretary of State.
