Some importance seems to be attached to the seizure of
the blockade-runner Virgiaius six miles from Jamaica by the Spanish gunboat Tornado. The Virginias had 165 passengers on board, *chiefly insurgents, among them a son of Cespedes, the insurgent President, and they are all being tried as pirates at Santiago. With the Volunteers to overrule the Courts, they will all, of course, be executed ; but as they seem all to be Spanish sub- jects, there is no right of interference, except on grounds of humanity, which would be scouted as ridiculous. It is just possible, however, that the Captain-General's telegram may contain some mistake about the distance from Jamaica, and that the Virginias may have had American papers, in which ease the "stern resolve" of the Volunteers may be a little dangerous. Blockade-runners are not pirates. It is quite useless for Castelar to interfere, as the Volunteers have already announced to him in very decided terms that if he interferes with slavery they will proclaim. Don Carlos. It would be well for Spain if they did, andif he betook himself toreign in Cuba, but the United States might object.
