 New York, Oct. 17.-The official trial of the battleship Maine was made on Long Island souhd this sfternoon. It demonstrated to the board and to the proprietors of the Quintard iron. works of this city, who built the machinery, that the vessels engines will make the 5000 collective indicated horse power called for in the contract with the navy department and somethingDver. <
 The Maine left the anchorage off the Pequot house, att the entrance of the London harbor, at noon. When the anchor was at the bow she turned in half her length and headed out through the Race and then eastward toward Block Island. Her manoeuvering pleased Captain Bunce and his aides exceedingly. When off Watch Hill, south east of Fishers Island, the helm was put over and turning in the arc of a great circle toward Montauk Point, she swung around to the westward and headed back through the Race. The wind from the westward was fresh and gave promise of an increase.
 When Race Rock light was abeam at 1:50 the trial, begun twenty minutes before, was fairly under way The duties of the engineer judges called for the taking of data showing the develop ment of power in the main engines as regarded by diagrams taken from indi- cators at both ends of the three cylin- ders, and also on the auxiliaries named in the contract as we'll as the steam pressure at the boilers and at the en- zines, the number of revolutions per minute, the amount of force draught and other factors to determine the re- suit.
 These observations by the trial board were taken in eight periods of ten min- utes each during the four hours. At the end of the four hours (5:30 p.m.), off Stamford light, a final reading of the indicators was made. During the four hours under forced draught the general average of steam pressure was Al pounds at the boilers, and not far from the designed average of 135 pounds at the cylinders, the propellers making 127 revolutions per minute on sustained average during the four hours, the vacuum being approximately twenty six inches.
 As the ship got further up the sound toward New York the wind increased until the cloud of spray from the bow wave were at times thrown over the flying bridge. The temperature at the cylinders under the protective deck in the engine room was 180 degrees, and on an average of 146 degrees, while in, the fire rooms it was from 1S0 degrees to 115 degrees. ' The. president of the official board, Chief Engineer Ayres, at the close of the run had nothing but praise for the ap- parent results attained and the smooth ness with which everything had passed off. He said the members of his corps would be busy at the navy yard work ing out the data for several days, and that the full report would go to Chief Engineer Melville at Washington about the middle of next week.
 Although the trial was for horse power, the speed of the Maine was also noted. For twenty-five miles her av- craze speed was about 15.ss knots per hour, and with the allowance for tide the result Is 7.25.
 The trial ended, the ship came on to the end of the sound, and shortly after 8 o'clock the anchor was dropped of Whifestone, and Chisf Melville and other guests, with members of the trial board, took the train for New York.
