Interesting Intelligence from Hayti and St. Domingo.

By Captain McIntyre, of the schooner Enterprise, arrived on Monday night, in eleven days, from Cape Haytien, we have been furnished with the following items of news:—

The Emperor of the Republic of Hayti had issued an edict, to take effect on the 5th instant, that no foreign merchant should be permitted to do any business under $1800, Spanish, per year, in place of $600, as heretofore; or any foreign clerk, unless he paid $1000. No vessel will allowed to take more than five tons of wood per ton her cargo at the port. The export duty on coffee and logwood was 150 Haytien per cent, or 1 1-2 per cent instead of 50, as heretofore; and in the same ratio on all articles. He had fixed a price on all goods imported and exported. He was adding 50 more St. Domingo troops to those already in the island. Business was very dull.

We learn from Capt. McIntyre, that schooners Jane and Eliza, which arrived yesterday week from Port au Prince, confirm the late news of the total defeat of Soulouque; the news had just reached Port au Prince when the schooner left.

A meeting was about to take place, to take into consideration the better mode of defending the country against the Haytians. Logwood, American provisions are getting scarce. The Emperor of Hayti was expected on the 20th, destination supposed to be for Jacmel.

Orders had been given that the Emperor was to march on St. Domingo on the 20th, with the whole army, for the Spanish part of the island.

The United States frigate St. Lawrence was at St. Thomas waiting orders. The British brig of war Persian, was at Jacmel on the 24th, looking after British property.

PROCLAMATION.

Buenaventura Baez, President of the Dominican Republic, to the Haytians.

HAYTIENS!—The fleet belonging to the Republic of Dominica addresses you, in the name of his fellow-citizens, and in the solemn conduct of an act of war, which for nearly six years ago that we separated from you, and built up a separate government, you have constantly made war against us, pretending to force us again to be united to one. We may yet live as good neighbors, though two distinct nations. We have invited you to do this, by proposing a peace, which is necessary to us, as well as to you; but, up to this time, you have rather preferred to force you to leave your country to go into exile, or to be slaughtered, as so many of you as were unwilling. Recollect your suffering in the march through our desert, and the terrible disaster at Ocoa; re-enter into yourselves, for what can you achieve in a war where you have gained no glory, and where you have only spent your resources? We have always contented ourselves with defending ourselves against aggression; this is the first time that we have taken the offensive to make war upon you, and to show you that we can hurt you in your own homes. We make war upon you on your own soil—on your properties—on your persons; without a fleet, without any defence, offering yourselves an easy prey to flames and pillage. Our cities are going to disappear, and their inhabitants to be driven into the woods.

Haytiens! Our fleet, well armed, well equipped, well commanded, having numerous troops on board, has set sail to cruise on your coast and intercept your shipping. Watch, then, night and day, on the North, on the West, on the South. Drive your wives and children into the morasses, abandon your towns to the power of the flames and the rain—and then when you go into the woods to perish of hunger and misery, you may accuse your leaders, whose insane policy has brought all these sufferings already upon you. You suffer already, dreadfully, by the war; you have lost your resources, the country is in ruins through the tyranny you labor under. See, then, whether you will suffer this to continue, or whether you will not have peace; we wish to live in peace and happiness, each in his own territory, each under his own laws, under the government of his own choice; but if your rulers will not have it so, Well, then, be it so! Let all the blood that will be spilt fall upon those who cause it—not upon us, who will not force them to better measures.

By the President, BUENAVENTURA BAEZ.

Minister of War, J. E. AYBAR.

St. Domingo, Oct. 19, 1849.
