Famous quotes containing the words solitary and/or tract:
“Wherever a man separates from the multitude, and goes his own way in this mood, there indeed is a fork in the road, though ordinary travelers may see only a gap in the paling. His solitary path across lots will turn out the higher way of the two.”
—Henry David Thoreau (1817–1862)
“My only companions were the mice, which came to pick up the crumbs that had been left in those scraps of paper; still, as everywhere, pensioners on man, and not unwisely improving this elevated tract for their habitation. They nibbled what was for them; I nibbled what was for me.”
—Henry David Thoreau (1817–1862)
