Steamboat Mount Pleasant.—There is great reason to fear (says the New York Commercial Advertiser) that this boat is lost, and that all on board have perished. She sailed from New York about 5 o'clock on the afternoon of Tuesday, the 10th instant, for Philadelphia. The wind then came up fresh from the north, and increased to a gale before midnight. The probability is that she rolled her boiler overboard and foundered. We learn that the boat she carried was too small to hold her crew, even if they had the opportunity of using it. The Mount Pleasant had been purchased by Messrs. McMain and Schober, of Philadelphia, to run to Lewistown, Delaware. Mr. McMain was on board with a crew which he brought on from Philadelphia. We can only learn the name of one of them, Captain Clifton, the pilot. The engineer, Erastus Hilton, was from Albany, where he has left a wife and two children.
