Mr. Seward to Mr. Sanford.

No. 136.]

Sir: I have received your despatch of July 14, No. 203, which announces the arrival of the Niagara at Antwerp, and her early departure from that port on a cruise for the Florida. That pirate, when last heard from, was capturing unarmed vessels near our coast. The vessels which we sent out in chase have, thus far, failed to find her.

I am, sir, your obedient servant,

WILLIAM H. SEWARD.

Henry S. Sanford, Esq., &c., &c., &c., Brussels.
