Simmer On The Cuban Question

New York, November 18. - The Tribinne to-morrow publishes the f ollowing letter of Senator Sumner, which was to have been read at the Cuban indignation meeting last night, but which the coiumittee state was received too late : BOSTON, November 10.

Nor can we forget the noble President, whose eloquent voice, pleading for humanity and invoking our example, has so often charmed' the world.
