Famous quotes containing the words crop and/or milk:
“The prairies were dust. Day after day, summer after summer, the scorching winds blew the dust and the sun was brassy in a yellow sky. Crop after crop failed. Again and again the barren land must be mortgaged for taxes and food and next year’s seed. The agony of hope ended when there was not harvest and no more credit, no money to pay interest and taxes; the banker took the land. Then the bank failed.”
—Rose Wilder Lane (1886–1968)
“In marble halls as white as milk,
Lined with a skin as soft as silk,
Within a fountain crystal-clear,
A golden apple doth appear.
No doors there are to this stronghold,
Yet thieves break in and steal the gold.”
—Mother Goose (fl. 17th–18th century. In marble walls as white as milk (Riddle: An Egg)
