Nowadays, there are a lot of different sorts of transport: from bicycles to trains, from sport cars to jets and other.
But at the same time, people don't think about the way they are travelling, the most important is to travel from one place to another.
However, history has seen a lot of revolutionary kinds of transport and one of them is steamboat, powered by the steam, that has won the hearts of many Americans.
Over the history, many people tried to construct a steamboat but only in 1807 The Clermont has accomplished this goal and made a voyage. After that the steamboat has was rising and became a very famous kind of transport in terms of water travelling and even became a symbol of the Misisippi.
Currently, no one uses steamboats in their daily life but it still remains to be a significant part of the history.
