Famous quotes containing the words form and/or constant:

    In many places the road was in that condition called repaired, having just been whittled into the required semicylindrical form with the shovel and scraper, with all the softest inequalities in the middle, like a hog’s back with the bristles up.

    Henry David Thoreau (1817–1862)
