Famous quotes containing the words original and/or owners:
“The inspired scribbler always has the gift for gossip in our common usage ... he or she can always inspire the commonplace with an uncommon flavor, and transform trivialities by some original grace or sympathy or humor or affection.”
—Elizabeth Drew (1887–1965)
“The work of the miner has its unavoidable incidents of discomfort and danger, and these should not be increased by the neglect of the owners to provide every practicable safety appliance. Economies which involve a sacrifice of human life are intolerable.”
—Benjamin Harrison (1833–1901)
