...Thoreau's Journal: 05-May-1859
Am struck by the beauty of the yellow birches, now fairly begun to be in bloom, at Yellow Birch, or Botrychium, Swamp. It is perhaps the handsomest tree or shrub yet in bloom (apparently opened yesterday), of similar character to the alders and poplars, but larger and of higher color. You see a great tree all hung with long yellow or golden tassels at the end of its slender, drooping spray, in clusters at intervals of a few inches or a foot. These are all dangling and incessantly waving in the wind, —a great display of lively blossoms (lively both by their color and motion) without a particle of leaf. Yet they are dense enough to reveal the outline of the tree, seen against the bare twigs of itself and other trees. The tassels of this one in bloom are elongated to two or three times the length of those of another not in bloom by its side. These dancing tassels have the effect of the leaves of the tremble. Those not quite open have a rich, dark, speckled or braided look, almost equally handsome. Golden tassels all trembling in the gentlest breeze, the only signs of life on the trees. A careless observer might not notice them at all. The reawakened springy life of the swamp, the product of its golden veins. These graceful pendants, not in too heavy or dense masses, but thinly dispersed with a noble moderation. Great vegetable chandeliers they stand in the swamp.
