in Thoreau’s Journal:

Methinks the truly weather-wise will know themselves––& find the signs of rain in their own moods––the aspect of their own skies or thoughts & not consult swallows & spiders–– 

I incline always [to] questions about the weather without thinking.  Does a mind in sympathy with nature need a hygrometer?  [Entry for August 26, 1852:  Rain Rain.]
