Famous quotes containing the words signal and/or head:
“Change begets change. Nothing propagates so fast. If a man habituated to a narrow circle of cares and pleasures, out of which he seldom travels, step beyond it, though for never so brief a space, his departure from the monotonous scene on which he has been an actor of importance would seem to be the signal for instant confusion.... The mine which Time has slowly dug beneath familiar objects is sprung in an instant; and what was rock before, becomes but sand and dust.”
—Charles Dickens (1812–1870)
“It was always startling to discover so plain a trail of civilized man there. I remember that I was strangely affected, when we were returning, by the sight of a ring-bolt well drilled into a rock, and fastened with lead, at the head of this solitary Ambejijis Lake.”
—Henry David Thoreau (1817–1862)
