Water exposed to the sun's rays becomes tired and lazy, curls up and sleeps.

"I knew that my father transported hundreds of thousands of cubic metres of beechwood over long distances, never, however, during the day, but at nights and generally when the moon shone. The reason for doing it this way, as my father often explained, was because water exposed to the sun's rays is tired and lazy and therefore curls up and sleeps. At night, however, and especially in moon light, the water becomes fresh and lively and is able to support the logs of beech and silver fir which are in fact heavier than water."
