Every fresh condition of light brings out new features. They are not the same in the morning and the afternoon; sunshine makes them very different from a gray sky; and heavy rain, which hangs still in drops from every leaf and twig, changes them still more. This time the tree-trunks were the most noticeable feature. Thoreau speaks of rain waking the lichens into life, and we saw this as never before. Not only does it bring out the colors and give a brightness and richness they show at no other time, but it raises the leaves--if one may so call them--makes them stand out fresh. The beeches were marvelous with many shades of green, and of pink, from a delicate blush over the whole tree, to bright vermilion in small patches. The birches, "most shy and ladylike of trees," were intensely yellow; some lovely with dabs of green, while others looked like rugged old heroes of many battles, with great patches of black, and ragged ends of loosened bark fringing them like an Indian's war dress, up to the branches. Every hollow under the trees had become a clear pond to reflect these beauties, and lively little brooks rippled across the path, adding to the woods the only thing they lacked,--running water. Instinctively our feet turned up the path to the oven-bird's nest, so narrow that we brushed a shower from every bush. There he was, singing at that moment. "Teacher! teacher! teacher!" he called, with head thrown up and wings drooped. And then while we looked he left his perch, and passed up between the branches out of our sight, his sweet ecstatic love-song floating down to delight our souls. Surely, we thought, all must be well in the cabin among the dead leaves, or he could not sing so. Yet life had not been all rose-colored to the little dame whom we had surprised several days before, bringing great pieces of what appeared to be lace, to line the nest she had made so wonderfully. We had watched her, breathless, for a long time, while she went back and forth carrying in old leaves, softened, bleached, and turned to lace by long exposure, arranged each one carefully and moulded it to place by pressing her breast against it, and turning round and round in the nest. Curious enough she looked as she alighted at some distance, and walked--not hopped--to her little "oven," holding the almost skeletonized leaf before her like an apron, so busy that she did not observe that she had visitors. Then came a day when, on reaching our usual place, we found that an accident had happened. The dainty roof was crushed in, and the poor little egg, for which such loving preparations had been made, lay pathetically on the ground outside the door. My comrade crept carefully up, raised the tiny roof to place, and with deft fingers put a twig under as a prop to hold it, then gently laid the pretty egg in the lace-lined nest.
