Mr. Foster to SeƱor Bolet Peraza.

Sir: I have the honor to acknowledge the receipt of your telegram of the 14th instant, asking that the steamer South Portland should be detained until the arrival of your principal witness to prove her violation of the neutrality laws of the United States.

In reply, I have the honor to state that I have transmitted a copy of your telegram to the Secretary of the Treasury, who will take proper action.

Accept, sir, etc.,
