Mr. Fish, Secretary of State, to Mr. Robeson, Secretary of the Navy.

Sir: I have the honor to inclose herewith a transcript of a communication from the United States marshal for the southern district of New York, of yesterday’s date, and will thank you to inform me if a vessel subject to the orders of the Navy Department can, without detriment to the public service, be directed to assist the marshal in preventing the departure from New York, or that vicinity, of any unlawful expeditions in aid of the Cuban insurgents, to which the marshal refers, as believed to be in course of preparation.

I have the honor to be, &c.,

HAMILTON FISH.

Hon. Geo. M. Robeson,
Secretary of the Navy.
