MISSION TO ST. DOMINGO.

The late mission of the Hon. John Hogan, of Illinois, to the Island of St. Domingo, has been made the subject of comment in the public journals. Mr. Hogan is now here, and has made, or is about to make his report, on the subject of his mission, to the President of the United States. From a remote period, as is well known, before Mr. Hogan was selected for this important service, the Haytians, who had usurped the island, and for a long period, during which period they had exercised the most arbitrary and exterminating warfare against the Spanish inhabitants, causing large numbers to abandon their homes and property, and seek refuge in foreign countries. Vast numbers emigrated to the United States, and their descendants are now among the most respectable of our citizens. A large body of the Spaniards, however, remained on the Island, notwithstanding these persecutions, and finally, in 1844, succeeded in shaking off the oppressive yoke. The new government established by them is similar, in its prominent features, to that of the United States.

From all the information which Mr. Hogan has been enabled to collect, we learn that he is fully of the opinion that the Dominican government will be able to maintain their independence, and that they will ultimately be recognized by European governments. The probability is, indeed, that a very few years will not elapse, before they will extend their control over the whole island; and for the moral and physical condition of the Haytians is such that they cannot hope for any length of time to contend single-handed with the Dominicans.

The American people, for many reasons, when this subject is properly understood, will feel a deep interest in the results. Independently of the light as soon as the Dominican government shall be established, the descendants of those formerly belonging to the French refugees, will undergo a change—or rather the descendants now residing in the United States, who will not only return to the island of their fathers, will necessarily bring back with them American ideas, principles, and it is but reasonable to suppose that St. Domingo will, through these causes, ultimately become essentially American.

In a commercial point of view the success of the Dominicans is a matter of the very highest importance to the United States. With a government like our own established in the island, the sympathies of the people will naturally be with us—and our trade with St. Domingo will ultimately be vastly increased. In a military and naval point of view, the acknowledgment of her independence by the United States is equally important.

The mission of Mr. Hogan, it will thus be seen, is one of far more importance to the United States than has been generally supposed. The duties of the mission, I understand, have been discharged with signal ability, and with entire satisfaction to the government. It seems to be the impression of all who have given the subject the proper degree of investigation, that Congress should act promptly in this matter, and in accordance with the undoubted interests of the American people.
