Famous quotes containing the words pack and/or year:
“A man was to live in that egg-shell day and night, a mile from the shore.... Think of making your bed thus in the crest of a breaker! To have the waves, like a pack of hungry wolves, eying you always, night and day, and from time to time making a spring at you, almost sure to have you at last.”
—Henry David Thoreau (1817–1862)
“It had been cold since December. Snow fell, first,
At New Year and, from then until April, lay
On everything. Now it had melted, leaving
The gray grass like a pallet, closely pressed;
And dirt. The wind blew in the empty place.”
—Wallace Stevens (1879–1955)
