A time ball is a now obsolete time signalling device. It consists of a large, painted wooden or metal ball that is dropped at a predetermined time, principally to enable navigators to verify their marine chronometers from their ships offshore. Accurate timekeeping is one means by which longitude can be determined at sea.

“Once upon a time there were three little foxes
Who didn’t wear stockings, and they didn’t wear sockses,
But they all had handkerchiefs to blow their noses,
And they kept their handkerchiefs in cardboard boxes.”

I saw him rack up thirty-eight or forty
In one home game. His hands were like wild birds.”
