The Virginius, a steamer sailing from New York under American colors, was seized on her way from Jamaica to Cuba by a Spanish cruiser, the Tornado, on the ground that she was carrying men and munitions of war to the Cuban insurgents, and a large number of those on board were summarily executed by order of the Spanish authorities in that island. The intelligence caused much excitement, especially in the City of New York, which was the centre of Cuban interests in this country. An indignation meeting was held in that City, which was countenanced by persons of high character and position, and addressed by Hon. William M. Evarts and others in speeches of great intensity. Mr. Sumner, taking a view of the case which the sober second thought of the people approved, but which was not in accord with the passions of the hour, answered an invitation to attend the meeting by the following letter:—

Boston, November 15, 1873.

GENTLEMEN,—It is not in my power to be with you at your meeting to ask for justice in Cuba.

Allow me to add, that, longing for immediate Emancipation in this neighboring island, where Slavery still shows its infamous front, and always insisting that delay is contrary to justice, I do not think it practicable at this moment, on existing evidence, to determine all our duties in the recent case where civilization has received a shock.

It is very easy to see that no indignation at dreadful butchery—inconsistent with the spirit of the age, but unhappily aroused by an illicit filibustering expedition from our own shores, kindred to that of the Alabama, for which England has been justly condemned in damages—can make us forget that we are dealing with the Spanish nation, struggling under terrible difficulties to become a sister Republic, and therefore deserving from us present forbearance and candor. Nor can we forget the noble President, whose eloquent voice, pleading for humanity and invoking our example, has so often charmed the world. The Spanish Republic and Emilio Castelar do not deserve the menace of war from us.

If watchwords are needed now, let them be: Immediate Emancipation and Justice in Cuba!—Success to the Spanish Republic!—Honor and Gratitude to Emilio Castelar! and Peace between our two Nations! Bearing these in mind, there will be no occasion for the belligerent preparations of the last few days, adding to our present burdensome expenditures several millions of dollars, and creating a war fever to interfere with the general health of the political body.

I am, Gentlemen,

Your faithful servant,
