From October, or Autumnal Tints by Henry David Thoreau:
“By the sixth of October the leaves generally begin to fall, in successive showers, after frost or rain; but the principal leaf-harvest, the acme of the Fall, is commonly about the sixteenth. Some morning at that date there is perhaps a harder frost than we have seen … and now, when the morning wind rises, the leaves come down in denser showers than ever. They suddenly form thick beds or carpets on the ground, in this gentle air, or even without wind, just the size and form of the tree above. Some trees … appear to have dropped their leaves instantaneously…. Down they have come on all sides, at the first earnest touch of autumn’s wand, making a sound like rain.”
