The undersigned has the honor to inform the Honorable Secretary of State that, having transmitted his communication by cable to the Government of His Catholic Majesty, he is now instructed to make the following demands: 1st. That the Federal Government shall deliver Señor Don Manuel Blanco, His Catholic Majesty's Consul at Charleston, S.C., alleged to be Leon Sangrado, a fugitive from justice from the Republic of Chili, to the undersigned, at the Legation of Spain at Washington, by or before the first day of February, proximo. 2. That the Federal Government shall address to the Government of His Catholic Majesty a formal and solemn apology for the insult offered by the arrest of said Blanco. And, in further proof thereof, shall, on said first day of February, at noon, cause the Spanish flag to be hoisted over Fort Columbus, in New York Harbor; Fort Warren, in Boston Harbor; the Navy Yard, in Washington; and at the mast-head of the flag-ship of the North Atlantic squadron--then and there to be saluted with twenty-one guns. I have the honor, etc., ANTONIO MANTILLA. The reply sent by Secretary Blaine to this peremptory demand was, as might be expected, an equally peremptory refusal. Thereupon the Spanish Minister demanded his passports, and with his Legation left the country. The passports of the American Minister at Madrid were at the same time forwarded to him, and he returned to the United States. Blanco was delivered to the Chilian representatives, and duly extradited, his wife accompanying him. The anti-administration newspapers commented with great severity upon the case, alleging that undue haste was manifested in forwarding the proceedings; that proper opportunity was not afforded the accused to establish his true identity; that the warrant of extradition was illegal, inasmuch as it had been issued by an Assistant Secretary of State during the absence of both the President and Secretary from Washington, and that, consequently, there had been in fact no real review of the proceedings by the Executive. The administration journals, on the contrary, found the extradition of the prisoner to be perfectly within the letter of the law; but were not inclined to say much on this point, preferring rather to applaud Mr. Blaine's new proof of a "vigorous foreign policy," as exemplified in the previously quoted correspondence with the Spanish Minister. * * * * * I.
