After Apple Picking by Robert Frost

"Essence of winter sleep is on the night" Line 7

 I like that this line prelude to the character falling asleep. With the words sleep and snow in the same sentence, I am made to think of soft pillow and drowsiness. This line gives an insight into the thought that the character is going to fall asleep and that way you know before it happens. It makes the poem interesting in a way.
