The little purple flowers of the sourgrass begin to open as the sun emerges. A while later, another mass of cloud drags its shade across the land and the flowers close up again. This has been going on all afternoon. The sunlit times are astonishingly bright, and the cloudy times make dark threats of storm, but no more rain has fallen. But even the days darkest clouds are edged with brilliant white. It is all splendidly moody and pleasantly cool. This is perfect spring weather, and there has been too little of it this year. I don't even care of the rain splits the ripening cherries open. It's worth it just to see this moody sky and those great swaths of light and shadow sweeping the rumpled mountainsides.
