aigaiu—The Madrid Gazelle, of the 21st inst., publishes a decree

"reincorporating" San Domingo with Spain. The Ministry, in an address to the Crown, declare that slavery, the " inevitable evil" of the other colonies of Spain, will never be re-established in the island, but the Dominicans "will joyfully accept the administrative organi- zation the Queen may deem proper to establish." It is possible that these promises may be kept to the ear, and that the Captain-General of San Domingo may find it as profitable to compel the whole popu- lation to work for the State as to re-establish slavery. The tempta- tion to every officer to enrich himself by conniving at the slave trade will however, as in Cuba, be almost irresistible. The legality of General Santana's act is questioned in France, as the Constitution gave him no power to sell the republic ; but that is an idle discussion. Conquests are never legal, and this is a conquest, the conquerors being called in by a faction of the conquered. The true point is the nature of the guarantees taken from Spain against slavery, and on this point we fear England has been remiss. The Haytien Govern- ment is reported to be both indignant and alarmed, while Ha ties envoys have been sent to Paris to demand the protection of the Emperor.
