Famous quotes containing the word marks:
“Now only a dent in the earth marks the site of these dwellings, with buried cellar stones, and strawberries, raspberries, thimble-berries, hazel-bushes, and sumachs growing in the sunny sward there.... These cellar dents, like deserted fox burrows, old holes, are all that is left where once were the stir and bustle of human life, and “fate, free will, foreknowledge absolute,” in some form and dialect or other were by turns discussed.”
—Henry David Thoreau (1817–1862)
