Sunny and still at mid-morning, with backlit leaves at the woods’ edge looking even yellower than they are. The throb of a distant engine. Squirrel teeth chiseling open a walnut. A common yellowthroat pipes up.

After all-night rain, most of the stiltgrass in the meadow has fallen over, and many of the white snakeroot heads are bent low. And even as some leaves on the trees are turning yellow, others have never looked so bright green.
