Famous quotes containing the word frost:
“On every tree a bucket with a lid,
And on black ground a bear-skin rug of snow.
The sparks made no attempt to be the moon.
They were content to figure in the trees
As Leo, Orion, and the Pleiades.
And that was what the boughs were full of soon.”
—Robert Frost (1874–1963)
