Famous quotes containing the word period:
“We are in a period when old questions are settled and the new are not yet brought forward. Extreme party action, if continued in such a time, would ruin the party. Moderation is its only chance. The party out of power gains by all partisan conduct of those in power.”
—Rutherford Birchard Hayes (1822–1893)
