Manifests Destiny - The Princeton

In 18 forty is also the dawn of, not the dawn, but it's the early days of the steam age of ocean going. The very first steam vessels would have been 20 or 30 years before by this point. They were paddle wheel driven, aren't they still? And in this case, there is a new us Navy warship called the princeton that everyone in the navy is very excited about. It's a steam engine powered by anthracite coal, which is more effective furnace. So itsa more effective engine. Manifests destiny.
