Marine Review (Cleveland, OH), 5 Nov 1899

J. W. Westcott of Detroit announces that in accordance with arrangements made by the Lake Carriers' Association with Duff & Gatfield of Amherstburg, changes in draught of water in the vicinity of the Lime-Kilns crossing, Detroit river, will be shown from the coal docks of Stanley B. Smith & Co. and the Cuddy-Mullen Coal Co. The figures on coal docks showing the stage of water will be illuminated by night. The same information may be obtained at the office of J. W. Westcott, foot of Woodward avenue, Detroit. No charge will be made for this service, but captains calling Duff & Gatfield by telephone will do so at their own expense.
