Welland Canal

The breach which at present interrupts the navigation of that canal detains some seventy vessels with their cargoes and threatens them with a Winter's berth in the interior of Canada. The break itself will, as we understand, be repaired in a few days, and the ice, should it form, will be cut through; but there is another difficulty still more formidable. At the point where the canal enters Lake Ontario, the action of the waves has thrown up a sand bar which can be dredged out in calm weather only, and without the removal of which no vessel can escape. Any wind, and particularly one from the Northwest, would render dredging entirely out of the question. The chances are about even for and against getting the vessels out this Winter. Should there be a failure to effect this, the cargoes must be stored to await the opening of Spring navigation, which will occasion serious inconvenience and loss. The propeller Ontario, with a load of produce from Cleveland, lies near the break. We are glad to learn that her accident some time since in Cleveland harbor did no injury to her hull.--Efforts of the most energetic kind are making to extricate the numerous craft thus caught in the Welland Canal, and we trust they will prove successful.--Rochester American.
