in Thoreau’s Journal:  

1 AM.  Moon waning.  To Conantum— A warm night.  A thin coat sufficient.  I hear an apple fall.  Meet a man going to market thus early.  There are no mists to diversity the night—its features are very simple. I hear no whippoorwill or other bird—  See no fire flies— Saw a whippoorwill? flutter across the road. Hear the dumping sound of frogs on the river meadow, and occasionally a kind of croak as from a bittern there. It is very dewy & I bring home much mud on my shoes. This is a peculiarity of night—its dews—water resuming its reign. Return before dawn— Morning & evening are more attractive than midnight.

I will endeavor to separate the tide in my thoughts, or what is due to the influence of the moon, from the current distractions & fluctuations. The winds which the sun has aroused go down at evening, and the lunar influence may then perchance be detected.

Of late I have not heard the wood-thrush.
