“The City of New York is like an enormous citadel, a modern Carcassonne. Walking between the magnificent skyscrapers one feels the presence on the fringe of a howling, raging mob, a mob with empty bellies, a mob unshaven and in rags.”
—Henry Miller (1891–1980)
“The Indian remarked as before, “Must have hard wood to cook moose-meat,” as if that were a maxim, and proceeded to get it. My companion cooked some in California fashion, winding a long string of the meat round a stick and slowly turning it in his hand before the fire. It was very good. But the Indian, not approving of the mode, or because he was not allowed to cook it his own way, would not taste it.”
—Henry David Thoreau (1817–1862)
