In 1858, a French engineer, Aime thome de Gamond, arrived in England with a plan for a twenty-one mile tunnel across the English Chanel. He said that it would be possible to build a platform in the Centre of the Chanel. This platform would serve as a port and a railway station. The tunnel would be well-ventilated it tall chimneys were built above sea-level. In 1860, a better plan was put forward by an Englishman, William low. He suggested that a double railway tunnel should be built. this would solve the problem of ventilation, for if a train entered this tunnel, it would draw in fresh air behind it. forty-two year later a tunnel was actually begun. if, at the time, the British had not feared invasion, it would have been completed. Recently, there has again been great interest in the idea of a channel tunnel. if it is built, it will connect Britain to Europe for the first time in history.
