Loss Of A Steamer - The steamer Commodore Barrie, Captain Patterson, from Niagara for Kingston, with a cargo of flour, was completely wrecked on the night of Saturday last, off Presque Isle. The Commodore Barrie and the schooner Canada having come in collision, during the night, the former was so much injured that she afterwards sunk. The Captain, crew and passengers remained on board as long as there appeared to be any prospect of the steamer being saved; and at last they were obliged to go on board the Canada, and proceed with her to Kingston, where they arrived in safety, on Sunday afternoon. The Commodore was owned by a joint stock company at Kingston; was chartered by D. Bethune, Esquire, and others, and had on board five hundred barrels of flour belong to Mr. Smith, of Youngstown, N.Y.. She was an old boat, having been on Lake Ontario since 1834; she was of light build - and we are happy to add, that there were no lives lost. Moreover, the Commodore is the first steamer that has been lost on Lake Ontario. Every effort was made to save the vessel and cargo. The Royal Mail steamer Princess Royal, Captain Colcleugh, on her passage up from Kingston, on Monday last, traversed the lake in every direction, and succeeded only in discovering a part of the forward rail, and two barrels of flour. Since the loss of the Commodore, the wind having been chiefly about W.N.W., the cargo must have drifted to the south shore. - Tor. Col.
