in Thoreau’s Journal:

Has been a dew which wets the feet. & I see a very thin fog over the low ground… 

This is the gray morning––the sun risen–– a very thin mist on the landscape––the falling water smooth– Far below a screaming jay seen flying against the bare stems of the pines. The young oaks on the plain the pines stand here and there–the walls in Conantum pastures seen in the sun the little groves on the opposite side of the river lit up by it while I am shade–these are memorable & belong to the hour.
