Famous quotes containing the word branches:
“Think how stood the white pine tree on the shore of the Chesuncook, its branches soughing with the four winds, and every individual needle trembling in the sunlight,—think how it stands with it now,—sold, perchance, to the New England Friction-Match Company!”
—Henry David Thoreau (1817–1862)
“...there is hope for a tree, if it is cut down, that it will sprout again, and that its shoots will not cease. Though its root grows old in the earth, and its stump dies in the ground, yet at the scent of water it will bud and put forth branches like a young plant. But mortals die, and are laid low; humans expire, and where are they?”
—Bible: Hebrew, Job 14:7-10.
“What are the roots that clutch, what branches grow
Out of this stony rubbish?”
—T.S. (Thomas Stearns)
