The small peterboat died out in the mid-nineteenth century, having evolved into the larger 'bawley' which could be around 30 feet long with sails. They were particularly popular around Leigh, where they were used for shrimp fishing. Meanwhile, growing pollution was driving fishing boats out of London altogether: by the end of the century, the Greenwich whitebait fisheries which had used these boats disappeared. (Ironically, for some time before that, the pollution in the water actually seemed to benefit the fish!) One of the city's characteristic craft thus vanished from its river.
