Famous quotes containing the word country:
“Roosevelt could always keep ahead with his work, but I cannot do it, and I know it is a grievous fault, but it is too late to remedy it. The country must take me as it found me. Wasn’t it your mother who had a servant girl who said it was no use for her to try to hurry, that she was a “Sunday chil” and no “Sunday chil” could hurry? I don’t think I am a Sunday child, but I ought to have been; then I would have had an excuse for always being late.”
—William Howard Taft (1857–1930)
“Thus, far from the beaten highways and the dust and din of travel, we beheld the country privately, yet freely, and at our leisure.”
—Henry David Thoreau (1817–1862)
