Mr. Olney to Mr. Dupuy de Lôme.

No. 13.]

Sir.: I have the honor to state that the Acting Secretary of the Treasury has referred to this Department, under date of the 24th instant, a letter from the collector of customs at New Orleans of the 19th, giving the result of the investigation made by Inspector Nemours Cousin at the instance of the Spanish consul at that city, that an expedition was fitting out from St. Tammany Parish, La., to aid the insurrection now in progress in Cuba. A thorough investigation was made by Mr. Cousin along the entire coast of the section in question, including all places accessible by boats of small draft, but no evidence was found, I have pleasure in saying, of an attempt to violate the neutrality laws of the United States.

Accept, etc.,

Richard Olney.
