chunk: After flying in a great storm for several days, the group crash-lands on a cliff-bound, volcanic, unknown island, described as being located at 34°57′S 150°30′W, about 2,500 kilometres (1,600 mi) east of New Zealand. They name it "Lincoln Island" in honor of their president, Abraham Lincoln. With the knowledge of the brilliant engineer Smith, the five are able to sustain themselves on the island, producing fire, pottery, bricks, nitroglycerin, iron, a simple electric telegraph, a home on a stony cliffside called "Granite House", and even a seaworthy ship, which they name the "Bonadventure" (in honor of Pencroff, the driving force behind its construction). They also manage to figure out their geographical location.
