After a long mild stretch of winter the weather has turned properly cold now, and the ground is freezing in the woods. Last night it was minus three and today it is minus five in the afternoon. There is the sound of the wind lifting the branches of an oak tree. The moon is visible in the east and we have a low sun moving across the southern sky. The season has been mild and the spring plants have come up too early, so they now have to suspend their activity and sleep again through the cold weather.
