‘Like an ox’s breath’
“But what would interest you about the brook,
It's always cold in summer, warm in winter.
One of the great sights going is to see
It steam in winter like an ox's breath,
Until the bushes all along its banks
Are inch-deep with the frosty spines and bristles--
You know the kind. Then let the sun shine on it!"
— From “The Mountain,’’ by Robert Frost
