the Eastern Trust and Banking Company and the Consolidated Lake Superior Company had been. He also became president of the Waterbury Tool Company, which manufactured hydraulic equipment. His interest continued both in transportation projects and in the potential development of the area around Hudson Bay, where the Algoma Central had once been intended to stretch to. He advocated for another east–west transcontinental railway (the "North Railway") which would connect Montreal to James Bay and continue onward through the far north along the 60th parallel. Clergue was also an early lobbyist in the 1920s for the enlarging of the St. Lawrence navigational corridor, which would eventually proceed in the 1950s as the Saint Lawrence Seaway project, though he would not live to see it. During the First World War, he joined the board of Canadian Car and Foundry, where he worked to sell munitions to the Russian Empire. Finally, near the very end of his life, he attempted to sell Canadian railway equipment to Manchukuo following the Japanese invasion of Manchuria in the 1930s. Clergue died on January 19, 1939, in Montreal, and his remains were returned to the United States for burial at Mount Hope Cemetery in Bangor. Legacy Popular Canadian author Alan Sullivan's novel The Rapids (1920) is inspired by Clergue's life. In 1946, Sir James Dunn, the then owner of Algoma Steel, commissioned Sullivan to write Clergue's biography. Provisionally titled Before the Tide, it has never been published. Despite Clergue's dogged efforts to pursue integration of his various enterprises, they were ultimately broken apart piecemeal. While some, like the Gertrude and Elsie mines, did not survive the initial failure of the Consolidated Lake Superior Company at all, others survived in various forms even as the Lake Superior Corporation was unable to maintain its control of them. Clergue's pulp and paper mill was eventually acquired by the Abitibi Power and Paper Company in 1928, then by a succession of owners until its eventual closure in 2011. The Algoma Eastern Railway's 1930 lease to the Canadian Pacific Railway proceeded despite the Algoma Eastern earning a net profit in 1929, as the cash infusion from the lease was necessary to keep the Lake Superior Corporation afloat. The Algoma Central Railway evolved into the Algoma Central Corporation, and diversified into other transportation interests such as trucking and maritime shipping, as well as real estate.
