Third. The right to intervene may be justified by the very serious injury to the commerce, trade and business of our people, and by the wanton destruction of property and devastation of the island. Fourth. Aid which is of the utmost importance. The present condition of affairs in Cuba is a constant menace to our peace and entails upon this Government an enormous expense. With such a conflict waged for years in an island so near us, and with which our people have such trade and business relations; when the lives and liberty of our citizens are in constant danger and their property destroyed and themselves ruined; where our trading vessels are liable to seizure and are seized at our very door by warships of a foreign nation, the expeditions of filibustering that we are powerless altogether to prevent, and the irritating questions and entanglements thus arising--all these and others that I need not mention, with the resulting strained relations, are a constant menace to our peace and compel us to keep on a semi-war footing with a nation with which we are at peace. THE DESTRUCTION OF THE MAINE. These elements of danger and disorder already pointed out have been strikingly illustrated by a tragic event which has deeply and justly moved the American people. I have already transmitted to Congress the report of the Naval Court of Inquiry on the destruction of the battleship Maine in the harbor of Havana during the night of the 15th of February. The destruction of that noble vessel has filled the national heart with inexpressible horror. Two hundred and fifty-eight brave sailors and marines and two officers of our navy, reposing in the fancied security of a friendly harbor, have been hurled to death, grief and want brought to their homes and sorrow to the nation. The Naval Court of Inquiry, which, it is needless to say, commands the unqualified confidence of the Government, was unanimous in its conclusions that the destruction of the Maine was caused by an exterior explosion--that of a submarine mine. It did not assume to place the responsibility. That remains to be fixed. In any event the destruction of the Maine, by whatever exterior cause, is a patent and impressive proof of a state of things in Cuba that, is intolerable. That condition is thus shown to be such that the Spanish Government cannot assure safety and security to a vessel of the American navy in the harbor of Havana on a mission of peace and rightfully there.
