I have been reading about Turner’s connections with Brentford, Isleworth and Twickenham, and came across this etching, from 1819. It’s a view of the Thames at low tide, where the River Crane feeds into it. Isleworth Ait can be seen to the right of the picture. It is called Water Cress Gatherers, Rails Head Ferry Bridge. I have yet to come across any water cress along the river but it was identified (with some surprise) in a survey by The Crane Wildflower Explorers, some of whom I have now met as their gardens back onto the river.
