While the 'Rivers of England' was still in production, the engraver Thomas Lupton and Turner embarked on a similar series of mezzotints initially referred to as the 'Harbours of England', but termed the 'Ports of England' when published. Turner completed fourteen watercolours of what should have been a group of twenty-four and only three parts of the publication were issued. The work achieved a kind of completion in 1856 when all the watercolours associated with the project were finally engraved by Lupton and published accompanied by a text by John Ruskin. There are preparatory studies for several of the watercolours, such as that of Portsmouth.
