[Translation.]

Mr. Tassara to Mr. Seward.

The undersigned, her Catholic Majesty’s minister plenipotentiary, has just received information that a vessel (her name Pancas or Poncas) intends to leave to-night or to-morrow from New London as a privateer against Spain.

The undersigned begs the Secretary of State to give the necessary orders to stop said vessel. A telegraph from the Secretary of the Treasury to send the revenue cutter stationed at New London would secure her for information. More particulars will be sent directly to the State Department.

The undersigned avails of this occasion to reiterate to the honorable Secretary of State of the United States the assurances of his highest consideration.

GABRIEL G. TASSARA.

Hon. William H. Seward, &c., &c., &c.
