In spring, you can feel life stirring in the barest twigs and the silhouetted catkins look as if a diminutive duck has run across the sky. One day the twigs are just beginning to thicken and brighten and bulge; by the next they are covered in pincer-paired leaves and pale, lime-white or pink-tinged blossoms. There is nothing tentative about these vernal explosions. When the days are longer, it is all sap and fresh smells, and the liquid calls of birds hidden in the drifts of thicker foliage. The bark has been through it all before, but the craggy faces of cherry tress seems less pinched in the bright light. By early November, when it is all dank and dark, the woods have a different taste, which does not quite match the ember-fall, sugar-brown shaken leaves.
