Famous quotes containing the word shells:
“The only fruit which even much living yields seems to be often only some trivial success,—the ability to do some slight thing better. We make conquest only of husks and shells for the most part,—at least apparently,—but sometimes these are cinnamon and spices, you know.”
—Henry David Thoreau (1817–1862)
