Famous quotes containing the word country:
“I fasted for some forty days on bread and buttermilk
For passing round the bottle with girls in rags or silk,
In country shawl or Paris cloak, had put my wits astray,
And what’s the good of women for all that they can say
Is fol de rol de rolly O.”
—William Butler Yeats (1865–1939)
“No people require maxims so much as the American. The reason is obvious: the country is so vast, the people always going somewhere, from Oregon apple valley to boreal New England, that we do not know whether to be temperate orchards or sterile climate.”
—Edward Dahlberg (1900–1977)
