To appreciate the magnitude of Henry Hudson's discoveries, Mr. Rachlis precedes the itinerary with a picture of the times in which henry Hudson lived. From here, each successive voyage is launched -- the goal being a find a shorter passage to Chine. On his first voyage aboard the Hopewell, Hudson headed North toward the Pole. Unsuccessful, he repeated the attempt and again returned from Arctic waters. The third expedition for the Dutch East India Company abroad the Half Moon and the fourth for England aboard the Discovery were the most significant of Hudson's career. The events of all four trips, the sights and adventures reported, the stormy waters on which the men lived, both in and out of the vessels, are taken directly from log books and interpreted in clear informative style by the author. Students fascinated by this aspect of history will find this a well organized and detailed account. A World Landmark book.
