“Aug. 30. The clearness of the air which began with the cool morning of the 28th makes it delicious to gaze in any direction. Though there has been no rain, the valleys are emptied of haze, and I see with new pleasure to distant hillsides and farmhouses and a river-reach shining in the sun, and to the mountains in the horizon. Coolness and clarity go together.”
- Henry David Thoreau, 1854
