The crickets sang...

From Hush, Hush, It's Sleepytime,
illustrated by Mel Crawford, 1968

An excerpt:

     The crickets sang in the grasses.  They sang the song of summer's ending, a sad, monotonous song. "Summer is over and gone," they sang.  "Over and gone, over and gone.  Summer is dying, dying."

     The crickets felt it was their duty to warn everybody that summertime cannot last forever.  Even on the most beautiful days in the whole year -- the days when summer is changing into fall -- the crickets spread the rumor of sadness and change.

~ from Charlotte's Web, 

written by E.B. White

Of course, the season of summer doesn't actually end for another month still, but I always think of it as being over when school starts back up again.  I love this passage from Charlotte's Web, and how White personifies the crickets when he writes of them warning everybody, spreading rumors, and singing sad songs.  Who knew the noise an insect makes could convey so much?
