Famous quotes containing the words annual and/or yield:
“Time that scatters hair upon a head
Spreads the ice sheet on the shaven lawn;
Signing an annual permit for the frost....”
—Philip Larkin (1922–1986)
“A book should contain pure discoveries, glimpses of terra firma, though by shipwrecked mariners, and not the art of navigation by those who have never been out of sight of land. They must not yield wheat and potatoes, but must themselves be the unconstrained and natural harvest of their author’s lives.”
—Henry David Thoreau (1817–1862)
