A Port Dalhousie Vessel for Europe Direct. - We clip the following from the St. Catharines (C.W.) Journal: -- "Should there be water enough in the Canal (which is now let off most of the levels, to make the necessary repairs), on Wednesday next, Messrs. Muir will launch from their Dock, at Port Dalhousie, a fine 500 tons vessel; intended for the through European trade. She is named the Niagara of Montreal; her length is 148 feet; depth of hold 14 feet; and breadth of beam 26 feet 2 inches. Her model is a splendid one, and she is built in the most substantial and durable manner, with,we believe, copper fastenings and iron knees.
"She will be loaded at Hamilton early this spring, by Mr. Patton, of Quebec, with white oak, rock elm, staves and pine deals, and will probably sail direct for London, calling at Montreal to complete her load, which will be carried thither by another vessel, it being impossible for the Niagara to go through the lower Canals fully loaded.The Niagara will not probably return to this country until 1861, as we understand it is intended to put her into the Mediterranean trade. She may perhaps, make a trial trip to Oswego or Kingston, previous to sailing for Europe."
