During the last summer several vessels belonging to the merchant marine of this country, sailing in neutral waters of the West Indies, were fired at, boarded, and searched by an armed cruiser of the Spanish Government. The circumstances as reported involve not only a private injury to the persons concerned, but also seemed too little observant of the friendly relations existing for a century between this country and Spain. The wrong was brought to the attention of the Spanish Government in a serious protest and remonstrance, and the matter is undergoing investigation by the royal authorities with a view to such explanation or reparation as may be called for by the facts. The commission sitting in this city for the adjudication of claims of our citizens against the Government of Spain is, I hope, approaching the termination of its labors. The claims against the United States under the Florida treaty with Spain were submitted to Congress for its action at the late session, and I again invite your attention to this long-standing question, with a view to a final disposition of the matter. At the invitation of the Spanish Government, a conference has recently been held at the city of Madrid to consider the subject of protection by foreign powers of native Moors in the Empire of Morocco. The minister of the United States in Spain was directed to take part in the deliberations of this conference, the result of which is a convention signed on behalf of all the powers represented. The instrument will be laid before the Senate for its consideration. The Government of the United States has also lost no opportunity to urge upon that of the Emperor of Morocco the necessity, in accordance with the humane and enlightened spirit of the age, of putting an end to the persecutions, which have been so prevalent in that country, of persons of a faith other than the Moslem, and especially of the Hebrew residents of Morocco. The consular treaty concluded with Belgium has not yet been officially promulgated, owing to the alteration of a word in the text by the Senate of the United States, which occasioned a delay, during which the time allowed for ratification expired. The Senate will be asked to extend the period for ratification. The attempt to negotiate a treaty of extradition with Denmark failed on account of the objection of the Danish Government to the usual clause providing that each nation should pay the expense of the arrest of the persons whose extradition it asks.
