More maintenance going on, this time repairs to the ornate mill chimney of Saltaire's New Mill. It has scaffolding up one side and a scaffold framework at the top. I don't know what they are doing - pointing the stonework possibly? I wouldn't be surprised if they aren't clearing out all the bird droppings from the lantern at the top. Birds obviously roost and possibly even nest in the tower and there are always some flying in and out. I don't suppose it does the structure a lot of good over a long period of time.
