FROM HAYTI AND ST. DOMINGO.

—The Boston Traveller of the 28th ult. notices the arrival of the Mary Chilton, from Hayti. The accounts by the Chilton are up to the 29th of March; and her commander, Capt. Skirvan, states that Soulouque's army was at least 15,000 strong, and that he had taken measures to prevent the cowardice of his soldiers by ordering those who exhibited any signs of wavering to be instantly shot down. Some think that he will enter St. Domingo without the firing of a gun; others that a bloody battle will ensue. Capt. Balcom gives some curious statements in regard to the mortality of the new regiments, &c. He says that the government stores are opened twice a week, when the canaille is called in for their coffee, which should be, according to the law, equally divided. Many, however, in the rush die—as, in one case mentioned, one man got 15,000 pounds, another 2000, and a third 4000. The Haytien officers are, evidently, not averse to a bribe.

The New York Herald gives the news brought by the Sarah Jane and the Mary and Elizabeth, whose arrival is mentioned by our correspondent "Indicator." The Herald says:

'There were two arrivals at this port, yesterday, from the island of Hayti: the brig Sarah Jane, Capt. Washburn, with dates from the city of St. Domingo to the 29th of March; and the schooner Mary and Elizabeth, Capt. Smith, from Maragone, whence she sailed on the 7th of April. We are indebted to Captains Smith and Washburn for papers, and for verbal information in regard to the affairs of the island. It seems that the war between the Haytiens and the Dominicans has commenced right earnestly. The city of St. Domingo was placed under martial law, about the 22d ult., and all the men of the city who were capable of bearing arms were mustered and marched out, under their President, to meet the Haytien President Soulouque, who, with his black army, was supposed to be advancing towards the city. A battle took place on the 18th of March, which resulted disastrously to the Dominicans, they having lost 42 men killed, a great number wounded, and prisoners, and several pieces of artillery—the towns of San Juan and St. John falling into the hands of the Haytiens. The force of President Soulouque was constantly increasing; a body of 700, from Jacmel, passed through Maragone on the 2d inst., on their way to Port-au-Prince and head-quarters, while others were gathering from all quarters. A decisive battle was expected to take place soon; and the chances of success appear to be in favor of the Haytiens. A flotilla, consisting of five war-vessels, with 500 troops on board, recently left St. Domingo for Azua, where it was thought a severe battle would be fought.... The U. S. sloop-of-war Albany arrived at St. Domingo on the 10th, and left for Aux Cayes on the 13th; officers and crew all well. The U. S. sloop-of-war Germantown was daily expected at St. Domingo.'
