A river caught fire four times. The first fire was an accident. The second fire was a warning. The third fire was a spectacle and people came from the city to watch it burn. The fourth fire was quiet and small and nobody saw it because it happened at four in the morning and the only witness was a man who had come to the river to drown himself. He saw the flame on the water and changed his mind. He went home. The river kept burning. It is still burning now but you have to come at the right hour to see it.
