On Friday, as “the Archer”, Grand Canal passage [passenger] boat, was proceeding from Dublin, Miss Gibson, of Parsonstown, one of the passengers, fell from the landing place, leading to the state cabin, into the canal, between the 11th and 12th locks. The boat was going rapidly at the time, and the lady was whirled under the water, and would inevitably have been drowned, but for the heroic decision of a young gentleman, son of Captain Brennan, of Strangford, county of Down, who instantly jumped from on board, and with the assistance of the master of the boat, and a countryman, rescued her from her impending fate.
