I helped push a lock gate or two for boats passing through, while I was sitting on the bench by the lock. Some men came to trim branches by the canoe portage spot, before the weir. I didn't think they had planted this toy, while pruning, but having hung around there, looking for birds - a heron, ducks and moorhens or a cormorant liked to be on the weir - it was only then that I spotted it for the first time, stuffed in a metal tube. Strange I hadn't noticed it before.
