in Thoreau’s Journal:
This is a beautiful day, warm but not too warm, a harvest day (I am going down the railroad causeway), the first unquestionable and conspicuous autumnal day, when the willows and button-bushes are a yellowed bower in parallel lines along the swollen and shining stream. The first autumnal tints (of red maples) are now generally noticed. The shrilling of the alder locust fills the air. A brightness as of spring is reflected from the green shorn fields. Both sky and earth are bright. The first clear blue and shining white (of clouds). Cornstalk-tops are stacked about the fields; potatoes are being dug; smokes are seen in the horizon. It is the season of agricultural fairs. If you are not happy to-day you will hardly be so to-morrow.
