in Thoreau’s Journal:

Yesterday having been a rainy day, the air is now remarkably clear and cool and you rarely see the horizon so distinct. The surface of the earth, especially looking westward, —grass grounds, pastures, and meadows, — is remarkably beautiful.

I stand in Heywood’s pasture… leaning over the wall, look westward. All things — grass, etc. — are peculiarly fresh this season on account of the copious rains.
