Chicago, Oct. 29. -- Dispatches received here yesterday by the owner of the schooner PENSAUKEE, which sailed from here on the 18th with 35,500 bushels of wheat, for Buffalo, state that the vessel was sunk in the St. Clair River, six miles above the entrance to the St. Clair Flats Canal. The tug which was towing the PENSAUKEE became disabled, and to prevent collision with her the schooner's anchors were let go. The water is shallow at that place, and the anchor fluke tore a hole in her bottom, with the result stated. The wheat belongs to B. P. Hutchinson, the big dealer of this city.
