Shanghai Modern – Even when it comes to washing the streets down in 1932

Since its earliest days as a treaty port Shanghai always used sprinklers on its streets – a big help when horse and cart was the main conveyance and equine pee was a major problem that needed washing away. 1932 though and Shanghai does away with its old horse and cart watering carts and introduced motorised sprinklers. Just in time too – when trouble with the Japanese came and the Settlement needed defending the American Marines turned the sprinkler cart into their water wagon.
