“How the cold creeps as the fire dies at length
How drifts are piled,
Dooryard and road ungraded,
Till even the comforting barn grows far away,
And my heart owns a doubt
Whether ‘tis in us to arise with day
And save ourselves unaided.”
—Robert Frost (1874–1963)

—François Rabelais (1494–1553)

“Farmers in overalls and wide-brimmed straw hats lounge about the store on hot summer days, when the most common sound is the thump-thump-thump of a hound’s leg on the floor as he scratches contentedly. Oldtime hunters say that fleas are a hound’s salvation: his constant twisting and clawing in pursuit of the tormentors keeps his joints supple.”
—Administration in the State of Arka, U.S. public relief program (1935-1943)
