An evening swim from a rowboat ended Monday night in the death of Wilbur Montmorency, 22, of Clinton township, who drowned in an effort to overtake the boat which drifted out into the lake with Miss Kathleen Clark of Beamsville. Montmorency, who had attended the Calvary Gospel Church service and picnic in Clinton on the lawn of his parents, had gone out in the rowboat with Miss Clark. When the boat was some 100 yards offshore, Montmorency plunged into the lake for a swim. While he was swimming, Miss Clark lost one of the oars. A strong swimmer, Montmorency retrieved the oar and then attempted to overtake the boat which was being carried out into the lake by a strong offshore wind. Meanwhile, Rev. Mr. Benson of Calvary Gospel Church, accompanied by another man, obtained a motor boat and went to the rescue of the pair. They were approaching Montmorency when he suddenly disappeared under the waters. They reached Miss Clark, who by this time had drifted a mile out in the lake.
