This is a story from the Great Explorers collection.
Here are the stories of nine great adventures and the lives of the men who took part in them. They pushed back the frontiers of man's knowledge of the world by their vision, courage, and sheer doggedness. They were very different people, from bold adventurers facing the unknown with enjoyment to careful, more scientific individuals. Their journeys are placed within their historical context, but also contain the words of the men themselves.
