CUBA.
The people of the United States have been kept in a state of excitement during a portion of the last month by reports of a revolution in the Island of Cuba. It is not yet possible to discover very clearly, what are the facts, but it is certain, that there were insurrectionary movements commencing about the 4th of July, in several parts of the Island; that they were badly planned, and inefficiently executed, and that the whole attempt, having caused the ruin of a vast number of persons, is at an end, and has resulted in the firmer establishment of the Spanish authority.
