No. 576.

Mr. Frelinghuysen to Mr. Valera .

Sir: Referring to your note of the 15th instant, communicating a report of fresh movements against the peace of Cuba, I have the honor to say that, as appears by letters of the 17th instant and later, the Attorney General and the Secretaries of the Treasury and Navy Departments have given strenuous instructions to their officers in and about Key West (some of which have already been carried out), to the end of preventing by all possible methods the threatened violation of our neutrality laws.

Accept, &c.,
