At the time of the Spanish American War, our giant water oaks were still a very popular building material for ships. When people first saw these trees, it was believed they had a corner on the world furniture market... trouble was they split apart when the wood cures. But just before throwing in the towel, someone put the idea of 'wet' and 'water oak' together and thus launched Jacksonville into a brisk ship building locale.
