CANADA RESTORES FRENCH FORTRESS: In the l8th Century when France ruled in the New World; Cape Breton Island played a key role in coastal defenses. Fort Louisbourg was a mighty citadel that changed hands many times between the English and the French as they fought for control of Quebec and Eastern Canada. Now the Fort is being restored and frogmen are recovering artifacts from beneath the waters near the redoubt where many ships were sunk. The Canadians hope to have the restoration completed in time for Canada's Centennial Year in 1967.
