After two days’ travel, the girls began to realize that Canada is quite empty. At school, they had learned that most Canadians live   71   a few hundred kilometres of the USA border, and Canada’s population   72   only slightly over thirty million, but now they were amazed   73   see such an empty country. They went through a wheat-growing province and saw farms   74   covered thousands of acres.   75   dinner, they were back in an urban area, the busy port city of Thunder Bay at the   76   of the Great Lakes. The girls were surprised at the   77   that ocean ships can sail up the Great Lakes. Because of the Great Lakes, they learned, Canada has more fresh water   78   any other country in the world. In fact, it has one-third of the world’s total   79  water, and   80  of it is in the Great Lakes.
