Famous quotes containing the words process and/or brass:
“To exist as an advertisement of her husband’s income, or her father’s generosity, has become a second nature to many a woman who must have undergone, one would say, some long and subtle process of degradation before she sunk [sic] so low, or grovelled so serenely.”
—Elizabeth Stuart Phelps (1844–1911)
“You could almost see the brass on her gleaming,
Not quite. The mist was to light what red
Is to fire. And her mainmast tapered to nothing,
Without teetering a millimeter’s measure.
The beads on her rails seemed to grasp at transparence.”
—Wallace Stevens (1879–1955)
